Basic CPR

Question 1

Open Chest Cardiac Compressions

Answer 1

(1) after penetrating chest trauma;
(2) in the perioperative period before or after cardiothoracic surgery;
(3) during cardiac arrest caused by hypothermia, pulmonary embolism, pericardial tamponade, or abdominal hemorrhage;
(4) in cases of chest deformity in which closed chest CPR is ineffective;
(5) in penetrating abdominal trauma with deterioration and cardiac arrest; and
(6) in blunt trauma with cardiac arrest.

Question 2

Common causes of airway obstruction in an unconscious patient

Answer 2

occlusion of the oropharynx by the tongue and laxity of the epiglottis

Question 3

Terminating Resuscitation

Answer 3

until the patient recovers spontaneous respirations and cardiac output, the rescuer becomes exhausted, or the patient is pronounced dead

Question 4

therapeutic use of electricity in cardiac arrest to depolarize the entire myocardium to eliminate ventricular fibrillation or nonperfusing ventricular tachycardia so that coordinated contractions can resume

Answer 4

Defibrillation

Question 5

application of a synchronized e trical impulse to convert a still-perfusing tachydysrhythmia back to a normal sinus rhythm.

Answer 5

Electrical cardioversion
