Review questions: CPR

381. Describe the technique for providing ventilations by a lone rescuer?

Use of bag-mask ventilation is not recommended for a lone provider. When ventilations are performed by a lone provider, mouth-to-mouth or mouth-to-mask are more efficient. 

382. How does gastric inflation interfere with providing adequate ventilations?

Gastric inflation can elevate the diaphragm, restrict lung movement, and decrease respiratory system compliance.

383. What is the reason an oropharyngeal might be used in an unresponsive victim?  The use of oropharyngeal airways in patients with cardiac arrest, airways may aid in the delivery of adequate ventilation with a bag-mask device by preventing the tongue from occluding the airway. 

384. What are the indications for using a nasopharyngeal airway?

Nasopharyngeal airways are useful in patients with airway obstruction or those at risk for developing airway obstruction, particularly when conditions such as a clenched jaw prevent placement of an oral airway 

385. What are some indications for endotracheal intubation?

Indications for emergency endotracheal intubation are (1) the inability of the provider to ventilate the unconscious patient adequately with a bag and mask and (2) the absence of airway protective reflexes (coma or cardiac arrest). The provider must have appropriate training and experience in endotracheal intubation.
