*The Hypertoxic Test
- Determine arterial blood gas in room air
- Administer 100% O2 for 10 minutes
- Repeat blood gas. If PaO2 <150 mmHg (±20 kPa) one can assume central mixing is occuring
In the majority of cyanotic heart lesions the PaO2 should not exceed 10 kPa
Prostin E
A 1/4 tablet is given initially every hour p.o to keep the ductus open in all suspected congenital cyanotic heart lesions.
