ACLS Airway Management & Ventilation 2

Question 1

What is the primary sign of gastric inflation during bag-mask ventilation?

Accepted Answer

Increasing abdominal distension

Answer

Gastric inflation is identified by progressive abdominal distension and can lead to regurgitation and aspiration.

Question 2

What is the recommended pre-oxygenation approach before attempting endotracheal intubation in ACLS?

Accepted Answer

Non-rebreather mask at 15 L/min for 3 minutes

Answer

A non-rebreather mask at 15 L/min for at least 3 minutes maximizes oxygen reserve by denitrogenating the lungs before intubation.

Question 3

What is the Sellick maneuver and its purpose during endotracheal intubation?

Accepted Answer

Backward pressure on the cricoid to occlude the esophagus and reduce aspiration risk

Answer

The Sellick maneuver applies backward pressure on the cricoid cartilage, occluding the esophagus to potentially reduce passive regurgitation during intubation.

Question 4

For a patient with a mature tracheostomy in cardiac arrest, what is the first step in airway management?

Accepted Answer

Attempt ventilation directly through the tracheostomy stoma

Answer

Ventilation through a mature tracheostomy stoma provides the most direct access to the trachea and should be the first approach.

Question 5

During CPR, a sudden and sustained rise in ETCO2 from 15 to 40 mmHg most likely indicates:

Accepted Answer

Return of spontaneous circulation (ROSC)

Answer

A sudden sustained rise in ETCO2 is a reliable indicator of ROSC, as restored cardiac output delivers significantly more CO2 to the lungs.
