What causes a Tet spell?
Tet spells are caused by a rapid drop in the amount of oxygen in the blood. Tet spells are most common in young infants, around 2 to 4 months old. Toddlers or older children might instinctively squat when they’re short of breath. Squatting increases blood flow to the lungs.
Why does squatting help in tetralogy of Fallot?
Squatting is a compensatory mechanism, of diagnostic significance, and highly typical of infants with tetralogy of Fallot. Squatting increases peripheral vascular resistance (PVR) and thus decreases the magnitude of the right-to-left shunt across the ventricular septal defect (VSD).

What is the treatment for a tet spell?
Place infants with hypercyanotic spells in the knee-chest position and give oxygen; sometimes, opioids (morphine or fentanyl), volume expansion, sodium bicarbonate, beta-blockers (propranolol or esmolol), or phenylephrine may help. Repair surgically at 2 to 6 months or earlier if symptoms are severe.
How do you treat cyanotic spell?
Management of Cyanotic Spells Management of spells is by intervening to increasing systemic vascular resistance, reducing systemic blood flow (increasing afterload) and at the same time reducing pulmonary vascular resistance and increasing pulmonary blood flow. (0.1mg/kg) as a slow bolus over at least 3-5 minutes.
Why do blue babies squat?
A child with TOF might have sudden episodes of deep cyanosis, called “hypercyanotic spells” or “Tet spells,” during crying or feeding. Older children who have Tet spells will often instinctively squat down, which helps to stop the spell.
What are squats?
Squatting is the action of occupying an abandoned or unoccupied area of land or a building, usually residential, that the squatter does not own, rent or otherwise have lawful permission to use. The United Nations estimated in 2003 that there were one billion slum residents and squatters globally.
Can hole in heart cause death?
A hole in the heart A rupture in the septum, the tissue between the heart’s pumping chambers, will almost always leak blood, further weakening the heart. Within several weeks, the affected heart muscle turns to scar tissue, which can cause heart failure or lead to death.
What causes a globular heart?
An enlarged heart may be the result of a short-term stress on the body, such as pregnancy, or a medical condition, such as the weakening of the heart muscle, coronary artery disease, heart valve problems or abnormal heart rhythms.
