Pressure control settings for LTV

Postby Colleen54 » Sat Mar 05, 2016 5:25 pm

I was curious & want to understand what the guidelines are for the pressure control setting on Aubrey's LTV. Aubrey, sma type 1 has been at 18 since she was 1. She will be 3 in May. Is the pressure something That can stay the same as she grows or should that be increased? Thank you for any guidance.

Colleen,
Whether one is a new born or 80 years old you can give a normal breath (tidal volume) by applying about 18 cm H2O to the lungs. In a baby 18 cm gives about 100 ml and in an adult about 600 ml provided that the lungs have normal compliance. About 18 is fine but the "bottom line" is that the breathing rate and blood CO2 should be normal or else the settings probably need to be increased a bit.
