What is the method of ventilation that allows breathing spontaneously at two levels of positive pressure?

• A. Adaptive Pressure Ventilation (PAV)
• B. Continuous Positive Airway Pressure (CPAP)
• C. Pressure Regulated Volume Control (PRVC)
• D. Airway Pressure Release Ventilation (APRV)

Answer: (D)

Airway Pressure Release Ventilation (APRV) is the method of ventilation that allows for spontaneous breathing at two levels of positive pressure. In this mode, the patient can breathe spontaneously during the periods of release, which is set at a lower pressure, while there is also a higher pressure maintained during the therapeutic phase. This dual-pressure system facilitates both ventilation and oxygenation while allowing the patient control over their spontaneous breathing. The approach is particularly beneficial for patients with conditions such as Acute Respiratory Distress Syndrome (ARDS), as it promotes lung recruitment and gas exchange. The design of APRV allows for an extended time at higher pressures and a brief release phase, effectively improving lung mechanics and oxygenation.
