Flow-restricted, oxygen-powered ventilation devices (FROPVDs) are contraindicated in:
Answer: Pediatric patients under 12 years old
FROPVDs deliver high pressures that can cause barotrauma in pediatric patients whose small airways cannot safely handle the flow rates.
A non-rebreather mask (NRB) at 15 L/min delivers approximately what percentage of oxygen?
Answer: 90–95%
A properly fitted non-rebreather mask at 15 L/min delivers approximately 90–95% oxygen to the patient.
You are ventilating an apneic adult at 12 breaths/min with a BVM. After 2 minutes, EtCO2 climbs to 55 mmHg. You should:
Answer: Increase rate slightly or improve tidal volume to enhance CO2 clearance
A rising EtCO2 above 45 mmHg indicates hypoventilation; increasing rate or tidal volume will improve CO2 elimination.
Which maneuver is appropriate for opening the airway of a trauma patient with suspected spinal injury?
Answer: Jaw-thrust without head tilt
The jaw-thrust maneuver opens the airway by displacing the mandible anteriorly without moving the cervical spine.
A patient with a suspected tension pneumothorax shows tracheal deviation, absent breath sounds on the left, and JVD. Your immediate airway action is:
Answer: Maintain airway patency while your partner prepares for needle decompression
Tension pneumothorax requires needle decompression; your role is to maintain the airway while preparing for or performing that intervention.
When using a bag-valve-mask with two rescuers, the second rescuer's role is to:
Answer: Squeeze the bag while the first rescuer maintains a two-handed mask seal
Two-rescuer BVM technique has one provider maintain a two-handed E-C clamp seal while the second squeezes the bag, improving mask seal and ventilation volume.
