Studies show that there are more benefits with weaning nCPAP by decreasing pressure than having alternating "time-on and time-off" nCPAP.

We wean by lowering the pressure gradually, in the preterm to as low as 2cm H20.

I know that many use 4cm H20 as a lower limit.

The argument for this is that the pressure measured in the pharynx is close to zero when CPAP is set lower than 4 cm H20 (thus believed to not have any positive effects).

Still, we see many babies that benefit from low pressure CPAP (2-3).

Do you know any studies that show negative effects using low pressures? (Theoretically, it could give increased breathing effort without any significant CPAP effect).

Adding to thread can someone tells me how much maximum pressure we can use on cpap

Usually we use CPAP up to 7 but when we use BiPAP pressures are higher (9-10)

Hi Urban, do you have some references on the CPAP weaning by pressure?
