Final answer:
The knee-chest position is recommended for hypoxic/cyanotic infants with Tetralogy of Fallot to improve blood flow to the lungs and decrease cyanosis.
Step-by-step explanation:
The knee-chest position is a recommended position for hypoxic/cyanotic infants with Tetralogy of Fallot. This position helps to improve blood flow to the lungs, increase oxygenation, and alleviate cyanosis. In this position, the infant's knees are brought up towards the chest, while the head is positioned lower than the chest. This helps to increase systemic vascular resistance and decrease venous return.
