Children in this group were given the prone position after weaning from noninvasive mechanical ventilation and its effect on the physiologic symptoms of the children was examined.

Supine position group children were given supine position after weaning from noninvasive mechanical ventilation and the effects on physiologic symptoms were examined.

After the children in the prone position group were weaned from noninvasive mechanical ventilation according and started to breathe spontaneously, they were prone positioned and monitored for 120 minutes (2 hours) every 20 minutes (0.min, 20.min, 40.min, 60.min, 80.min, 100.min, 120.min) with a head-monitor for peak heart rate, oxygen saturation, respiratory rate and blood pressure.

Changes in the pulse rate of children will be measured and recorded at 20 minute intervals for 120 minutes after the position given to the children after weaning from noninvasive mechanical ventilation. The changes in the pulse rate values of the children between the age groups in the study in terms of minutes/pulse rate and the difference values between them according to minutes will be examined.

Changes in oxygen saturation values of children will be measured and recorded at 20 minute intervals for 120 minutes after the position given to children after weaning from noninvasive mechanical ventilation. The changes in % of oxygen saturation values of children between the age groups in the study and the difference values between them according to minutes will be analyzed.
