1. 3. The acute respiratory failure that can precipitate cardiac arrest in asthma patients is characterized by severe obstruction leading to air trapping. AEDs are highly accurate in their detection of shockable arrhythmias but require a pause in CPR for automated rhythm analysis. Other pseudoelectrical therapies, such as cough CPR, fist or percussion pacing, and precordial thump have all been described as temporizing measures in select patients who are either periarrest or in the initial seconds of witnessed cardiac arrest (before losing consciousness in the case of cough CPR) when definitive therapy is not readily available. This topic last received formal evidence review in 2010.5. β-Adrenergic receptor antagonists (“β-adrenergic blockers”) and L-type calcium channel antagonists (“calcium channel blockers”) are common antihypertensive and cardiac rate control medications. The majority of recommendations are based on Level C evidence, including those based on limited data (123 recommendations) and expert opinion (31 recommendations). There is no conclusive evidence of superiority of one biphasic shock waveform over another for defibrillation. Carbon monoxide poisoning reduces the ability of hemoglobin to deliver oxygen and also causes direct cellular damage to the brain and myocardium, leading to death or long-term risk of neurological and myocardial injury. The intent of precordial thump is to transmit the mechanical force of the “thump” to the heart as electric energy analogous to a pacing stimulus or very low-energy shock (depending on its force) and is referred to as, Fist, or percussion, pacing is administered with the goal of stimulating an electric impulse sufficient to cause depolarization and contraction of the myocardium, resulting in a pulse. In addition to standard ACLS, several therapies have long been recommended to treat life-threatening hyperkalemia. What is optimal for the CPR duty cycle (the proportion of time spent in compression relative to the Rescuers may experience anxiety or posttraumatic stress about providing or not providing BLS. 2. For a patient with suspected opioid overdose who has a definite pulse but no normal breathing or only gasping (ie, a respiratory arrest), in addition to providing standard BLS and/or ACLS care, it is reasonable for responders to administer naloxone. Verapamil is a calcium channel blocking agent that slows AV node conduction, shortens the refractory period of accessory pathways, and acts as a negative inotrope and vasodilator. Furthermore, many research studies have methodological limitations including small sample sizes, single-center design, lack of blinding, the potential for self-fulfilling prophecies, and the use of outcome at hospital discharge rather than a time point associated with maximal recovery (typically 3–6 months after arrest).3. 1. Each of the 2020 Guidelines documents were submitted for blinded peer review to 5 subject-matter experts nominated by the AHA. 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. Do prophylactic antiarrhythmic medications on ROSC after successful defibrillation decrease arrhythmia The use of an airway adjunct (eg, oropharyngeal and/or nasopharyngeal airway) may be reasonable in unconscious (unresponsive) patients with no cough or gag reflex to facilitate delivery of ventilation with a bag-mask device. This begins with opening the airway followed by delivery of rescue breaths, ideally with the use of a bag-mask or barrier device.

Energy setting specifications for cardioversion also differ between defibrillators.
