A ________ fracture occurs when the bone has broken through the skin.

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 result-ed in increased alveolar recruitment. c. High mean pressures caused by PC-IRV decreased cardiac output. d. Intrinsic PEEP caused by PC-IRV com-pressed the pulmonary capillaries.
