A nurse is caring for a client receiving mechanical ventilation via an endotracheal (ET) tube. The high-pressure alarm is beeping, and the client is experiencing respiratory distress. The nurse is unable to determine the cause of the alarm. Which of the following actions should the nurse take?
A.
Re-evaluate the client for an ET cuff leak.
B.
Assess for disconnected tubing.
C.
Decrease the ventilator flow rate.
D.
Deliver breaths manually with a resuscitation bag.
The correct answer and Explanation is :
The correct answer is D. Deliver breaths manually with a resuscitation bag.
When a client on mechanical ventilation via an endotracheal (ET) tube experiences respiratory distress and the high-pressure alarm is sounding, immediate action is needed to ensure adequate oxygenation and ventilation. The high-pressure alarm is typically triggered by increased resistance in the airway or the ventilator circuit. Causes include airway obstruction (e.g., secretions, kinked tubing), bronchospasm, or problems with the ET tube (e.g., displacement or obstruction).
In this situation, the nurse must address the client’s respiratory distress first. If the nurse cannot quickly identify and resolve the cause of the high-pressure alarm, it is critical to manually deliver breaths using a resuscitation bag (bag-valve mask) to ensure the client continues to receive adequate oxygenation. This is a life-saving measure that buys time while the nurse investigates and resolves the issue with the ventilator or ET tube.
Manual ventilation provides the nurse with more control over the pressure and volume of air delivered to the client, which can be beneficial in cases of airway obstruction. If the ET tube is blocked by secretions or other causes, suctioning should be performed promptly.
Other options, such as re-evaluating for an ET cuff leak or assessing for disconnected tubing, are important, but they are not the immediate priority when the client is in distress. Decreasing the ventilator flow rate is inappropriate, as it would not address the cause of the high-pressure alarm and could worsen the client’s respiratory status. Therefore, manual ventilation with a resuscitation bag is the priority intervention until the cause of the high-pressure alarm is resolved and the ventilator can be safely used again.
