and 4. Of the 250 recommendations in these guidelines, only 2 recommendations are supported by Level A evidence (high-quality evidence from more than 1 randomized controlled trial [RCT], or 1 or more RCT corroborated by high-quality registry studies.) reflex, and myoclonus/status myoclonus? 2. Arrests without a primary cardiac origin (eg, from respiratory failure, toxic ingestion, pulmonary embolism [PE], or drowning) are also common, however, and in such cases, treatment for reversible underlying causes is important for the rescuer to consider.1 Some noncardiac etiologies may be particularly common in the in-hospital setting. IV antiarrhythmic medications may be considered in stable patients with wide-complex tachycardia, particularly if suspected to be VT or having failed adenosine. Which statement about bag-valve-mask (BVM) resuscitators is true? The clinical signs associated with severe hyperkalemia (more than 6.5 mmol/L) include flaccid paralysis, paresthesia, depressed deep tendon reflexes, or shortness of breath.13 The early electrocardiographic signs include peaked T waves on the ECG followed by flattened or absent T waves, prolonged PR interval, widened QRS complex, deepened S waves, and merging of S and T waves.4,5 As hyperkalemia progresses, the ECG can develop idioventricular rhythms, form a sine-wave pattern, and develop into an asystolic cardiac arrest.4,5 Severe hypokalemia is less common but can occur in the setting of gastrointestinal or renal losses and can lead to life-threatening ventricular arrhythmias.68 Severe hypermagnesemia is most likely to occur in the obstetric setting in patients being treated with IV magnesium for preeclampsia or eclampsia. Resuscitation from cardiac arrest caused by -adrenergic blocker or calcium channel blocker overdose follows standard resuscitation guidelines. The controlled administration of IV potassium for ventricular arrhythmias due to severe hypokalemia may be useful, but case reports have generally included infusion of potassium and not bolus dosing. 1. Pulseless electrical activity is the presenting rhythm in 36% to 53% of PE-related cardiac arrests, while primary shockable rhythms are uncommon.35. Research on building emergency communications provides useful guidance on ways to communicate emergency information to improve public response and safety. While orienting a new medical assistant to the facility, you find a patient who is unresponsive in the exam room. Which technique should you use to open the patient's airway? Notably, when the QRS complex is of uniform morphology, shock synchronized to the QRS is encouraged because this minimizes the risk of provoking VF by a mistimed shock during the vulnerable period of the cardiac cycle (T wave). It does not have a pediatric setting and includes only adult AED pads. Rapidly intervening with patients admitted through emergency department triage C. Responding to patients during a disaster or multiple-patient situation D. Responding to patients after activation of the emergency response system When performed with other prognostic tests, it may be reasonable to consider bilaterally absent pupillary light reflex at 72 h or more after cardiac arrest to support the prognosis of poor neurological outcome in patients who remain comatose. It does not have a pediatric setting and includes only adult AED pads. To accomplish delivery early, ideally within 5 min after the time of arrest, it is reasonable to immediately prepare for perimortem cesarean delivery while initial BLS and ACLS interventions are being performed. Limited data are available from defibrillator threshold testing with backup transthoracic defibrillation, using variable waveforms and energy doses. In patients with confirmed pulmonary embolism as the precipitant of cardiac arrest, thrombolysis, surgical embolectomy, and mechanical embolectomy are reasonable emergency treatment options. One benefit to SSEPs is that they are subject to less interference from medications than are other modalities. Fire . Operationally, administering epinephrine every second cycle of CPR, after the initial dose, may also be reasonable. 3. Emergency response and disaster recovery. Medical Mini Guardian has the highest monthly fee ($39.95), and Bay Alarm Medical In-Home Preferred has the lowest monthly fee ($29.95) of our best PERS picks. Does preshock waveform analysis lead to improved outcome? All patients with evidence of anaphylaxis require early treatment with epinephrine. 2. The 2010 Guidelines recommended a 50% duty cycle, in which the time spent in compression and decompression was equal, mainly on the basis of its perceived ease of being achieved in practice. They may be used in patients with heart failure with preserved ejection fraction. Furthermore, the resource intensity required to begin and maintain an ECPR program should be considered in the context of strengthening other links in the Chain of Survival. Check for no breathing or only gasping; if none, begin CPR with compressions. You are providing high-quality CPR on a 6-year-old patient who weighs 44 pounds. Two RCTs of patients with OHCA with an initially shockable rhythm published in 2002 reported benefit from mild hypothermia when compared with no temperature management. All guidelines were reviewed and approved for publication by the AHA Science Advisory and Coordinating Committee and the AHA Executive Committee. When performed in combination with other prognostic tests, it may be reasonable to consider high serum values of neuron-specific enolase (NSE) within 72 h after cardiac arrest to support the prognosis of poor neurological outcome in patients who remain comatose. TTM between 32C and 36C for at least 24 hours is currently recommended for all cardiac rhythms in both OHCA and IHCA. It is reasonable for healthcare providers to perform chest compressions and ventilation for all adult patients in cardiac arrest from either a cardiac or noncardiac cause. In a trial that compared esmolol with diltiazem, diltiazem was more effective in terminating SVT. Compression rate and compression depth, for example, have both been associated with better outcomes, yet these variables have been found to be inversely correlated with each other so that improving one may worsen the other.13 CPR quality interventions are often applied in bundles, making the benefit of any one specific measure difficult to ascertain. Much of the published research involves patients whose arrests were presumed to be of cardiac origin and in settings with short EMS response times. Does targeted temperature management, compared to strict normothermia, improve outcomes? Cognitive impairments after cardiac arrest include difficulty with memory, attention, and executive function. 5. Historically, the best motor examination in the upper extremities has been used as a prognostic tool, with extensor or absent movement being correlated with poor outcome. In the rare situation when a lone rescuer must leave the victim to dial EMS, the priority should be on prompt EMS activation followed by immediate return to the victim to initiate CPR. When an IV line is in place, it is reasonable to consider the IV route for epinephrine in anaphylactic shock, at a dose of 0.05 to 0.1 mg (0.1 mg/mL, aka 1:10 000). On recognition of a cardiac arrest event, a layperson should simultaneously and promptly activate the emergency response system and initiate cardiopulmonary resuscitation (CPR). During cardiac arrest, if the pregnant woman with a fundus height at or above the umbilicus has not achieved ROSC with usual resuscitation measures plus manual left lateral uterine displacement, it is advisable to prepare to evacuate the uterus while resuscitation continues. When evaluated with other prognostic tests after arrest, the usefulness of rhythmic periodic discharges to support the prognosis of poor neurological outcome is uncertain. Accurate neurological prognostication is important to avoid inappropriate withdrawal of life-sustaining treatment in patients who may otherwise achieve meaningful neurological recovery and also to avoid ineffective treatment when poor outcome is inevitable (Figure 10).3. For an actuator that has an inside diameter of 0.500.500.50 in and a length of 42.042.042.0 in and that is filled with machine oil, calculate the stiffness in lb/\mathrm{lb} /lb/ in\mathrm{in}in. AEDs are highly accurate in their detection of shockable arrhythmias but require a pause in CPR for automated rhythm analysis. This concern is especially pertinent in the setting of asphyxial cardiac arrest. A 2015 systematic review found that prehospital cooling with the specific method of the rapid infusion of cold IV fluids was associated with more pulmonary edema and a higher risk of rearrest. 1. Team planning for cardiac arrest in pregnancy should be done in collaboration with the obstetric, neonatal, emergency, anesthesiology, intensive care, and cardiac arrest services. 3. If using a defibrillator capable of escalating energies, higher energy for second and subsequent shocks may be considered for presumed shock-refractory arrhythmias. The presence of undifferentiated myoclonic movements after cardiac arrest should not be used to support a poor neurological prognosis. Adenosine will not typically terminate atrial arrhythmias (such as atrial flutter or atrial tachycardia) but will transiently slow the ventricular rate by blocking conduction of P waves through the AV node, afford their recognition, and help establish the rhythm diagnosis. 4. Three studies evaluated quantitative pupillary light reflex. Both of these considerations support earlier advanced airway management for the pregnant patient. Agonal breathing is characterized by slow, irregular gasping respirations that are ineffective for ventilation. A recent systematic review found that no sonographic finding had consistently high sensitivity for clinical outcomes to be used as the sole criterion to terminate cardiac arrest resuscitation. When spinal injury is suspected or cannot be ruled out, rescuers should maintain manual spinal motion restriction and not use immobilization devices. Vasopressin alone or vasopressin in combination with epinephrine may be considered in cardiac arrest but offers no advantage as a substitute for epinephrine in cardiac arrest. What is the optimal approach to advanced airway management for IHCA? CT and MRI are the 2 most common modalities. All lay rescuers should, at minimum, provide chest compressions for victims of cardiac arrest. 2. We recommend that cardiac arrest survivors have multimodal rehabilitation assessment and treatment for physical, neurological, cardiopulmonary, and cognitive impairments before discharge from the hospital. 3. Seal the mask with two hands using the E-C technique. In patients who remain comatose after cardiac arrest, it is reasonable to perform multimodal neuroprognostication at a minimum of 72 hours after normothermia, though individual prognostic tests may be obtained earlier than this. In patients with -adrenergic blocker overdose who are in shock refractory to pharmacological therapy, ECMO might be considered. In cases of prehospital maternal arrest, rapid transport directly to a facility capable of PMCD and neonatal resuscitation, with early activation of the receiving facilitys adult resuscitation, obstetric, and neonatal resuscitation teams, provides the best chance for a successful outcome. 3. Which response by the medical assistant demonstrates closed-loop communication? Persons who enter the Main Accumulation Areas test the system by initiating a two-way conversation with Security each time they enter. Two randomized, placebo-controlled trials, enrolling over 8500 patients, evaluated the efficacy of epinephrine for OHCA.1,2 A systematic review and meta-analysis of these and other studies3 concluded that epinephrine significantly increased ROSC and survival to hospital discharge. 1. For synchronized cardioversion of atrial flutter using biphasic energy, an initial energy of 50 to 100 J may be reasonable, depending on the specific biphasic defibrillator being used. If a victim is unconscious/unresponsive, with absent or abnormal breathing (ie, only gasping), the healthcare provider should check for a pulse for no more than 10 s and, if no definite pulse is felt, should assume the victim is in cardiac arrest. In the PRIMED study (n=8178), the use of the ITD (compared with a sham device) did not significantly improve survival to hospital discharge or survival with good neurological function in patients with OHCA. Table 1. Cycles of 5 back blows and 5 abdominal thrusts. Throughout the recommendation-specific text, the need for specific research is identified to facilitate the next steps in the evolution of these questions. Unlike most other cardiac arrests, these patients typically develop cardiac arrest in a highly monitored setting such as an ICU, with highly trained staff available to perform rescue therapies. For cardiac arrest with known or suspected hyperkalemia, in addition to standard ACLS care, IV calcium should be administered. ACD-CPR is performed by using a handheld device with a suction cup applied to the midsternum, actively lifting up the chest during decompressions, thereby enhancing the negative intrathoracic pressure generated by chest recoil and increasing venous return and cardiac output during the next chest compression. Electrolyte abnormalities may cause or contribute to cardiac arrest, hinder resuscitative efforts, and affect hemodynamic recovery after cardiac arrest. A. Identifying and treating early clinical deterioration B. 1. Monday - Friday: 7 a.m. 7 p.m. CT A 2015 systematic review reported significant heterogeneity among studies, with some studies, but not all, reporting better rates of survival to hospital discharge associated with higher chest compression fractions. Lay and trained responders should not delay activating emergency response systems while awaiting the patients response to naloxone or other interventions. affect resuscitation outcomes? These recommendations are supported by the 2020 CoSTR for BLS.1. In a small clinical trial and several observational studies, waveform capnography was 100% specific for confirming endotracheal tube position during cardiac arrest. After successful maternal resuscitation, the undelivered fetus remains susceptible to the effects of hypothermia, acidosis, hypoxemia, and hypotension, all of which can occur in the setting of post-ROSC care with TTM. 6. CPR obscures interpretation of the underlying rhythm because of the artifact created by chest compressions on the ECG. Precordial thump is a single, sharp, high-velocity impact (or punch) to the middle sternum by the ulnar aspect of a tightly clenched fist. When Mr. Phillips shows signs of ROSC, where should you perform the pulse check? humidified oxygen? What is the optimal duration for targeted temperature management before rewarming? You do not see signs of life-threatening bleeding. Check for no breathing or only gasping and check pulse (ideally simultaneously). Adenosine is recommended for acute treatment in patients with SVT at a regular rate. WEAs are no more than 360 characters and include the type and time of the alert, any action you should take and the agency issuing the alert. Emergency drills are conducted in accordance with CF OP 215-4. An updated systematic review on several aspects of this important topic is needed once currently ongoing clinical trials have been completed. The toxicity of cyanide is predominantly due to the cessation of aerobic cell metabolism. Based on the training of the rescuers, and only if scene safety can be maintained for the rescuer, sometimes ventilation can be provided in the water (in-water resuscitation), which may lead to improved patient outcomes compared with delaying ventilation until the victim is out of the water. An exposure to patient blood or other body fluid. See Metrics for High-Quality CPR for recommendations on physiological monitoring during CPR. In patients with -adrenergic blocker overdose who are in refractory shock, administration of high-dose insulin with glucose is reasonable. This topic last received formal evidence review in 2010.5. -Adrenergic receptor antagonists (-adrenergic blockers) and L-type calcium channel antagonists (calcium channel blockers) are common antihypertensive and cardiac rate control medications. Beginning the CPR sequence with compression. 3. These recommendations are supported by the 2015 ACC/AHA/HRS Guideline for the Management of Adult Patients With SVT: A Report of the American College of Cardiology/AHA Task Force on Clinical Practice Guidelines and the Heart Rhythm Society.6, These recommendations are supported by the 2015 American College of Cardiology, AHA, and Heart Rhythm Society Guidelines for the Management of Adult Patients With SVT.6. Stop CPR, check for breathing and a pulse and monitor Mr. Sauer until the advanced cardiac life support team takes over. A clinical trial studied administration of magnesium in addition to sodium bicarbonate for patients with TCA-induced hypotension, acidosis, and/or QRS prolongation.5 Although overall outcomes were better in the magnesium group, no statistically significant effect was found in mortality, the magnesium patients were significantly less ill than controls at study entry, and methodologic flaws render this work preliminary. Management of acute PE is determined by disease severity.2 Fulminant PE, characterized by cardiac arrest or severe hemodynamic instability, defines the subset of massive PE that is the focus of these recommendations. outcomes? Other recommendations are relevant to persons with more advanced resuscitation training, functioning either with or without access to resuscitation drugs and devices, working either within or outside of a hospital. 3. Anticoagulation alone is inadequate for patients with fulminant PE. This cause of death is especially prominent in those with OHCA but is also frequent after IHCA.1,2 Thus, much of postarrest care focuses on mitigating injury to the brain. 2. 1. There is no evidence that cricoid pressure facilitates ventilation or reduces the risk of aspiration in cardiac arrest patients. Patients with 12-lead identification of ST-segment elevation myocardial infarction (STEMI) should have coronary angiography for possible PCI, highlighting the importance of obtaining an ECG for diagnostic purposes. 7. After immediately initiating the emergency response system, what is your next action according to the Adult In-Hospital Cardiac Chain of Survival? Findings in both animal studies and human case reports/case series on the effect of glucagon in calcium channel blocker toxicity have been inconsistent, with some reporting increase in heart rate and some reporting no effect. We recommend treatment of clinically apparent seizures in adult postcardiac arrest survivors. The duration and severity of hypoxia sustained as a result of drowning is the single most important determinant of outcome. Amiodarone or lidocaine may be considered for VF/pVT that is unresponsive to defibrillation. It is feasible only at the onset of a hemodynamically significant arrhythmia in a cooperative, conscious patient who has ideally been previously instructed on its performance, and as a bridge to definitive care. An irregularly irregular wide-complex tachycardia with monomorphic QRS complexes suggests atrial fibrillation with aberrancy, whereas pre-excited atrial fibrillation or polymorphic VT are likely when QRS complexes change in their configuration from beat to beat. Early high-quality CPR The nurse assesses a responsive adult and determines she is choking. You are alone and caring for a 9-month-old infant with an obstructed airway who becomes unresponsive. The combination of active compression-decompression CPR and impedance threshold device may be reasonable in settings with available equipment and properly trained personnel. It may be reasonable to administer IV lipid emulsion, concomitant with standard resuscitative care, to patients with local anesthetic systemic toxicity (LAST), and particularly to patients who have premonitory neurotoxicity or cardiac arrest due to bupivacaine toxicity. 4. 4. authorized emergency ambulance dispatch center for specific MPDS determinants in accordance with EMS Policy No. Chest compression depth begins to decrease after 90 to 120 seconds of CPR, although compression rates do not decrease significantly over that time window. Intracardiac drug administration was discouraged in the 2000 AHA Guidelines for CPR and Emergency Cardiovascular Care given its highly specialized skill set, potential morbidity, and other available options for access.1,2 Endotracheal drug administration results in low blood concentrations and unpredictable pharmacological effect and has also largely fallen into disuse given other access options. 2. Look for no breathing or only gasping, at the direction of the telecommunicator. This approach results in a protracted hands-off period before shock. Respiratory rate over 28/min or less than 8/min. In patients who remain comatose after cardiac arrest, we recommend that neuroprognostication be delayed until adequate time has passed to ensure avoidance of confounding by medication effect or a transiently poor examination in the early postinjury period. the functional capacity and safety of hospitals and the health-care system at large. Additional investigations are necessary to evaluate cost-effectiveness, resource allocation, and ethics surrounding the routine use of ECPR in resuscitation. Pharmacological treatment of cardiac arrest is typically deployed when CPR with or without attempted defibrillation fails to achieve ROSC. CPR indicates cardiopulmonary resuscitation. Administration of IV or IO calcium, in the doses suggested for hyperkalemia, may improve hemodynamics in severe magnesium toxicity, supporting its use in cardiac arrest although direct evidence is lacking. CPR is recommended until a defibrillator or AED is applied. The electric characteristics of the VF waveform are known to change over time. The topic of neuroprotective agents was last reviewed in detail in 2010. "The push has been to build up the experience of state teams to be able to respond quickly," she said. It may be reasonable to use a defibrillator in manual mode as compared with automatic mode depending on the skill set of the operator. The primary considerations when determining if a victim needs to be moved before starting resuscitation are feasibility and safety of providing high-quality CPR in the location and position in which the victim is found. You have assessed your patient and recognized that they are in cardiac arrest. Routine use of sodium bicarbonate is not recommended for patients in cardiac arrest. 5. Patient selection, evaluation, timing, drug selection, and anticoagulation for patients undergoing rhythm control are beyond the scope of these guidelines and are presented elsewhere.1,2. Postcardiac arrest care is a critical component of the Chain of Survival and demands a comprehensive, structured, multidisciplinary system that requires consistent implementation for optimal patient outcomes. Neuroprognostication that uses multimodal testing is felt to be better at predicting outcomes than is relying on the results of a single test to predict poor prognosis. Notably, in a clinical study in adults with outof- hospital VF arrest (of whom 43% survived to hospital discharge), the mean duty cycle observed during resuscitation was 39%. Routine administration of calcium for treatment of cardiac arrest is not recommended. *Red Dress DHHS, Go Red AHA ; National Wear Red Day is a registered trademark. Fever after ROSC is associated with poor neurological outcome in patients not treated with TTM, although this finding is reported less consistently in patients treated with TTM. The evidence for what constitutes optimal CPR continues to evolve as research emerges. Does avoidance of hyperoxia in the postarrest period lead to improved outcomes? The value of artifact-filtering algorithms for analysis of electrocardiogram (ECG) rhythms during chest compressions has not been established. Time taken for rhythm analysis also disrupts CPR. In a tiered ALS- and BLS-provider system, the use of the BLS TOR rule can avoid confusion at the scene of a cardiac arrest without compromising diagnostic accuracy. For patients with severe hypothermia (less than 30C [86F]) with a perfusing rhythm, core rewarming is often used. Rescuers may experience anxiety or posttraumatic stress about providing or not providing BLS. Hydroxocobalamin and 100% oxygen, with or without sodium thiosulfate, can be beneficial for cyanide poisoning. Alternatives to IV access for acute drug administration include IO, central venous, intracardiac, and endotracheal routes. 1. Cardiac arrest results in heterogeneous injury; thus, death can also result from multiorgan dysfunction or shock. 3. Before appointment, writing group members disclosed all commercial relationships and other potential (including intellectual) conflicts. The trained lay rescuer who feels confident in performing both compressions and ventilation should open the airway using a head tiltchin lift maneuver when no cervical spine injury is suspected. ECPR is a complex intervention that requires a highly trained team, specialized equipment, and multidisciplinary support within a healthcare system. outcomes? Which intervention should the nurse implement? 4. neurological outcome? The same anticonvulsant regimens used for the treatment of seizures caused by other etiologies may be considered for seizures detected after cardiac arrest. There are some physiological basis and preclinical data for hyperoxemia leading to increased inflammation and exacerbating brain injury in postarrest patients. and 2. As more and more centers and EMS systems are using feedback devices and collecting data on CPR measures such as compression depth and chest compression fraction, these data will enable ongoing updates to these recommendations. Arterial pressure monitoring by arterial line may be used to detect ROSC during chest compressions or when a rhythm check reveals an organized rhythm. In the presence of known or suspected basal skull fracture or severe coagulopathy, an oral airway is preferred compared with a nasopharyngeal airway. smell of smoke, visible flames, etc.) Which populations are most likely to benefit from ECPR? When significant CAD is observed during post-ROSC coronary angiography, revascularization can be achieved safely in most cases.5,7,9 Further, successful PCI is associated with improved survival in multiple observational studies.2,6,7,10,11 Additional benefits of evaluation in the cardiac catheterization laboratory include discovery of anomalous coronary anatomy, the opportunity to assess left ventricular function and hemodynamic status, and the potential for insertion of temporary mechanical circulatory support devices.
