AEMT Airway Management and Ventilation 3

Question 1

Flow-restricted, oxygen-powered ventilation devices (FROPVDs) are contraindicated in:

Accepted Answer

Pediatric patients under 12 years old

Answer

FROPVDs deliver high pressures that can cause barotrauma in pediatric patients whose small airways cannot safely handle the flow rates.

Question 2

A non-rebreather mask (NRB) at 15 L/min delivers approximately what percentage of oxygen?

Accepted Answer

90–95%

Answer

A properly fitted non-rebreather mask at 15 L/min delivers approximately 90–95% oxygen to the patient.

Question 3

You are ventilating an apneic adult at 12 breaths/min with a BVM. After 2 minutes, EtCO2 climbs to 55 mmHg. You should:

Accepted Answer

Increase rate slightly or improve tidal volume to enhance CO2 clearance

Answer

A rising EtCO2 above 45 mmHg indicates hypoventilation; increasing rate or tidal volume will improve CO2 elimination.

Question 4

Which maneuver is appropriate for opening the airway of a trauma patient with suspected spinal injury?

Accepted Answer

Jaw-thrust without head tilt

Answer

The jaw-thrust maneuver opens the airway by displacing the mandible anteriorly without moving the cervical spine.

Question 5

A patient with a suspected tension pneumothorax shows tracheal deviation, absent breath sounds on the left, and JVD. Your immediate airway action is:

Accepted Answer

Maintain airway patency while your partner prepares for needle decompression

Answer

Tension pneumothorax requires needle decompression; your role is to maintain the airway while preparing for or performing that intervention.
