Answer :
Final answer:
A high-pressure alarm on a mechanical ventilator can be caused by increased airway resistance, excessive secretions, and a disconnect in the ventilator circuit. Low tidal volume is not typically a cause for a high-pressure alarm.
Explanation:
The possible causes for a high-pressure alarm on a mechanical ventilator include, but are not limited to: A. Increased airway resistance, such as that caused by bronchoconstriction or airway obstruction, C. Excessive secretions, which can build up and block the airways, and D. Disconnect in the ventilator circuit, which would disrupt the intended flow of air into the patient's lungs. Option B. Low tidal volume is unlikely to cause a high-pressure alarm since low tidal volume usually indicates insufficient air reaching the lungs rather than an issue that would increase resistance or pressure in the system.
An allergic reaction that causes airways to swell can increase the resistance of the respiratory system, making it harder to breathe and potentially causing a high-pressure alarm on a ventilator.
