24
Q

What does AED stand for, and what two primary types do they come in?

Give details about both types.

A

Automated External Defibrillation

  • Fully automatic defibrillators; which analyze the patient’s cardiac rhythm, determine whether defibrillation is necessary, If necessary, deliver a shock
  • Semiautomatic Defibrillator: Analyzes patient’s cardiac rhythm, Determines whether defibrillation is necessary, If necessary, advises the operator to deliver a shock by pushing a button.

A

Airway
Breathing
Chest Compressions

37
Q

The initial process of chest compressions should begin with ______

A

30 compressions at a rate of 100 to 120 compressions/minute and a depth of 2 inches followed by the establishment of an airway and rescue breathing

38
