In what position might a toddler with a history of tetralogy of Fallot naturally assume during play?

A toddler with a history of tetralogy of Fallot may naturally assume a squatting position during play due to the physiological mechanics associated with their condition. Tetralogy of Fallot includes four defects that can lead to decreased oxygenation and increased workload on the heart. When a child with this condition is active or experiences exertion, they may become cyanotic or have decreased blood flow to the lungs, which can trigger a compensatory response.

Squatting is a reflexive action that helps to improve blood flow and oxygenation. By squatting, the child can increase the systemic vascular resistance, causing more blood to flow to the lungs for oxygenation. Additionally, this position can assist in alleviating the effects of right-to-left shunting, which is characteristic of tetralogy of Fallot. Therefore, the squatting position provides both physiological benefits and a sense of comfort for the child, making it a natural choice during playtime.

The other positions, while possible, do not provide the same physiological reassurance or benefit for a child with tetralogy of Fallot during episodes of increased activity or exertion. For instance, sitting or being in the supine position does not promote increased vascular resistance like squatting does. The left lateral recumb
