I stumbled upon this presentation which deals how to approach to a problem of congenital heart disease. In a newborn or an infant . It is clearly a master piece . A life time experience of a pediatrician condensed in 130 slides . It is from Kerala .India.
To quote an example from this presentation.
When you want to rule out urgently a congenial cyanotic heart disease in the bed side * What will you do ?
What is hyperoxia test ?
Axminster 100 % O2 . Measure satutration.If the PO2 crosses 200 , virtually any cyanotic heart disease is ruled out.
If it is less than 150 , it is very much likely the baby has a CHD !
(* Echocardigram may not be available everywhere . Even if it is there it needs a certain expertise to do it new-born )
