Corrección de la Temperatura del Paciente
La temperatura del paciente puede introducirse en el analizador IRMA
TRUpoint si se desvía de 37°C. Los valores del pH y los gases sanguíneos
medidos se vuelven a calcular a la temperatura introducida (T) mediante las
siguientes ecuaciones:
pH = pH
(T) (37°C)
pCO = pCO
2(T)
Ecuación del pO
pO = pO *10
