Burst suppression with identical bursts (suppression-burst ratio >50%) is a malignant EEG pattern indicating severe cortical injury post-arrest.

The BLS Survey, according to AHA guidelines, focuses on immediate life-saving actions for cardiac arrest. It involves quickly assessing for responsiveness, activating the emergency medical services (EMS) and retrieving an AED, initiating high-quality chest compressions to ensure circulation, and performing early defibrillation if a shockable rhythm is present. This sequence prioritizes rapid assessment and intervention.

An essential component of a dynamic and effective resuscitation team is having a single, clear team leader who directs actions, assigns roles, and ensures smooth communication. Multiple leaders can lead to confusion, conflicting instructions, and disorganization, hindering efficient patient care during a critical event. Clear roles, closed-loop communication, and knowing one's limitations are all vital for team success.

Adenosine 6 mg rapid IV push is the first pharmacological treatment for stable regular narrow-complex SVT.

For an adult patient in respiratory arrest who still has a pulse, the recommended ventilation rate using a bag-valve-mask is one breath every 5 to 6 seconds, which equates to 10 to 12 breaths per minute. This rate provides adequate oxygenation and ventilation without causing hyperventilation, which can negatively impact cardiac output and cerebral blood flow.

BP must be < 185/110 mmHg before alteplase administration and maintained < 180/105 mmHg for at least 24 hours afterward.
