Abstract
Some preterm infants require nasal-CPAP for optimal lung function even if they are : Ie and without supplemental oxygen requirements, as indicated by the drop in oxygenation ••. ables, the development of tachypnea, retraction and flaring after discontinuation of CP AP .d being put back on CP AP later on because of apnea, bradycardia, marked respiratory stress and respiratory acidosis. 2) Stable preterm infants without extra-oxygen requirements could sustain periods of ,terruption of CP AP without increasing the frequency of apneas and bradycardias or uencing their blood pressure and heart rate or their clinical outcome. 3) Preterm infants respond to discontinuation of CP AP in one of two ways; either by . eveloping apneas and bradycardias or by dropping in their oxygenation associated with achypnea and retractions. 4) of the variables at baseline or at one hour can predict which infant need to put ;ack on CPAP. However, at six hours the drop in aJAP02 ratio, and the development of ~etraetions and flaring are indications for reinstitutuion of CP AP therapy. 5) Gaseous gastric distention is a common problems in preterm infants treated by nasal¬:CP AP. Early discontinuation of CP AP could reduce this problem. 6) Nasal-CPAP in the chronic phase of treatment at low pressure levels (5 em H20) does r not lead to hypoxia, or CO2 retention, or did it influence blood pressure or heart rate significantly, or increase the risk of pneumothorax in preterm infants
