简要总结
Infants will be monitored by TcCO2 during three consecutive time periods of one hour each on a high and low rate of NIPPV, when in a stable condition. NIPPV rate will start high/low, changed to low/high and switched back to starting rate.
详细描述
This will be a prospective, crossover observational study that will be performed at Rambam NICU.
Infants will be monitored by TcCO2 during three consecutive time periods of one hour each on a high and low rate of NIPPV, when in a stable condition.
NIPPV rate will start high/low, changed to low/high and switched back to starting rate.
