A Patient Switched from Pressure-Controlled Continuous Mandatory Ventilation (CMV) with Positive

question 38

Multiple Choice

A patient switched from pressure-controlled continuous mandatory ventilation (CMV) with positive end expiratory pressure (PEEP) to pressure-controlled inverse ratio ventilation (PC-IRV) shows a good improvement in PaO₂ but a decrease in tissue oxygenation. Which of the following best explains this observation?

• A) High mean pressures caused by PC-IRV decreased pulmonary blood flow.
• B) Intrinsic PEEP caused by PC-IRV resulted in increased alveolar recruitment.
• C) High mean pressures caused by PC-IRV decreased cardiac output.
• D) Intrinsic PEEP caused by PC-IRV compressed the pulmonary capillaries.
