A systematic check of the prongs position can reduce the risk of lung hyperinflation (till airleak) due to higher level of
CPAP from those ordered by the physician. Systematic checks also decrease the risk of lung derecruitment due to prongs
dislocation which results in low CPAP levels. Excessive levels of CPAP increases intrathoracic pressure which may
depress cardiac output (reduced pre-load due to obstructed venous return; direct effect on myocardial contractility).
