Question

During pressure-targeted ventilation with a set pressure of 24 cm H2O, the patient coughs. The ventilator will do which of the following?

A) Inspiration will end immediately.

B) Inspiratory time will increase.

C) Inspiration will continue with the set pressure.

D) Inspiratory pressure will end at the maximum safety pressure.

Answer 1

The ventilator will continue inspiration with the set pressure when a patient coughs during pressure-targeted ventilation.

Step-by-step explanation:

When a patient coughs during pressure-targeted ventilation set at 24 cm H2O, the ventilator will typically react by option C) inspiration will continue with the set pressure. During a cough, there might be a transient increase in intrathoracic pressure, but the ventilator is designed to maintain the set inspiratory pressure until the predetermined inspiratory time is reached or until a maximum safety pressure threshold is exceeded. Modern ventilators have sophisticated algorithms to adapt to such situations and ensure consistent ventilation without causing harm to the patient. The inspiratory pressure does not end immediately nor does the time increase, and the set pressure is designed to stay constant unless safety limits are surpassed.
