Numerous proctological procedures involve the jackknife posture. One of the riskiest positions is jackknife. Due to venous pooling in the lower limbs and chest, the patient's mean arterial blood pressure may decrease. The reduced diaphragm movement may lead to a decrease in cardiac output and respirations.
