Question

Spontaneous breath modes include all of the following except:

A) pressure support ventilation (PSV)

B) continuous positive airway pressure (CPAP)

C) bilevel CPAP (BiPAP)

D) continuous mandatory ventilation assist-control

Answer 1

Spontaneous breathing modes, such as PSV, CPAP, and BiPAP, partially or entirely rely on the patient's breathing efforts. Continuous Mandatory Ventilation Assist-Control, however, controls the breathing cycle with a preset volume or pressure, not allowing for spontaneous breaths, thus it is not a spontaneous breath mode.

Step-by-step explanation:

The modes of spontaneous breath include those that allow the patient to control the breathing pattern to some extent. These modes include Pressure Support Ventilation (PSV), Continuous Positive Airway Pressure (CPAP), and Bilevel CPAP (BiPAP). However, Continuous Mandatory Ventilation Assist-Control is not classified as a spontaneous breathing mode because the ventilator completely controls the breathing cycle with a preset volume or pressure despite the patient’s own breathing efforts, allowing no room for spontaneous breathing effort.

Spontaneous breathing modes like PSV and BiPAP are designed to support the patients' own respiratory efforts, while CPAP maintains a steady level of pressure in a patient's airways to ensure they remain open, typically used in the treatment of sleep apnea. On the other hand, Continuous Mandatory Ventilation Assist-Control is a fully assisted ventilation mode where the ventilator provides full support to patient breathing, with no reliance on patient-initiated breaths.
