Question

Quizplus · Accepted Answer

Squatting is a spontaneous compensatory mechanism used by older children with Tetralogy of Fallot to alleviate hypoxic spells. Squatting and its variants increase systemic resistance while decreasing venous return to the heart from the inferior vena cava. Squatting does not reduce chest pain, control dizziness, or improve headaches.
