Question

4. Which of the following is true about emergency jet ventilation?

A. It is important to start the pressure low so that no trauma is caused to the lungs.
B. A blender should be used to decrease the amount of oxygen to prevent lung damage.
C. It should be performed through a large catheter placed in the cricothyroid membrane.
D. It cannot be performed without a specific jet ventilator.

Answer 1

Emergency jet ventilation requires starting with low pressure to avoid lung trauma and can be performed through a catheter in the cricothyroid membrane.

Step-by-step explanation:

The correct statement about emergency jet ventilation is that it is important to start the pressure low to avoid trauma to the lungs. In emergency situations where a patient's airway needs to be manually ventilated, care must be taken to prevent lung damage by using appropriate pressures. Jet ventilation can be performed via a catheter placed in the cricothyroid membrane which is smaller than tracheostomy tubes, allowing for air to be delivered to the lungs at a controlled, high velocity when conventional ventilation through the mouth or nose is not possible.

Option A alludes to the importance of beginning with a lower pressure to prevent barotrauma, or lung damage due to excessive pressure. It is essential to recognize that even in urgent scenarios, gentle initiation of pressure is key to minimizing harm to delicate lung tissues.
