For a patient in unacceptable ventilatory status with high peak inspiratory pressures, which mode is the most appropriate?

• A. Pressure Support Ventilation (PSV)
• B. Volume-Controlled IMV with PEEP
• C. Pressure-Controlled CMV with PEEP
• D. Minimum Mandatory Ventilation (MMV)

Answer: (C)

In the context of a patient exhibiting unacceptable ventilatory status with high peak inspiratory pressures, the most appropriate mode to utilize is Pressure-Controlled Continuous Mandatory Ventilation (CMV) with PEEP. This mode allows for better control over the peak inspiratory pressures by delivering breaths at a set pressure rather than a set volume. It can be particularly beneficial in situations where the patient's lung compliance is poor, which is often the case when high peak inspiratory pressures are observed. Pressure-Controlled CMV helps to reduce the risk of barotrauma and ventilator-induced lung injury by limiting the peak inspiration pressure, allowing for safer ventilation. The addition of PEEP can help improve oxygenation and prevent alveolar collapse, which can further enhance the patient’s ability to exchange gases and recover from their current condition. Other modes, while they have their uses, may not be as fitting for this specific patient scenario. For example, Volume-Controlled IMV with PEEP would involve delivering breaths based on a predetermined tidal volume, which might exacerbate the issue of high peak inspiratory pressures if the underlying lung mechanics are already compromised. Pressure Support Ventilation (PSV) may not provide adequate ventilation for patients in a critical state or those who cannot initiate their own breaths
