question 38

Multiple Choice

• 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.
