When a lung collapses, the affected lung is unable to participate in gas exchange, leading to a decrease in pulmonary blood flow. This decrease in pulmonary blood flow results in a decrease in cardiac output (CO), stroke volume (SVI), and pulmonary vascular resistance (PVR). Central venous pressure (CVP) is not directly affected by a collapsed lung.
