Endotracheal suctioning (ETS) is performed by nurses to remove secretion and debris from the tracheobronchial tree trough mechanical aspiration. Different types of ETS procedures are currently used in caring intubated patients. Suction may lead to serious complications such as significant hypoxemia and cardiac arrest, if not performed properly. The purpose of this study was to determine the effects, if not performed properly. The purpose of this study was to determine the effects of ETS with hyperinflation on arterial blood gases and pH in patient after cardiac surgery. Experiments were carried out on 30 patients who mechanically ventilated after cardiac surgery. Procedure was performed with 3 lung hyperinflation volume (1.5*VT), then disconnecting ventilator from patient and after that, ETS was done twice at a total time of 15 seconds immediately. At the end of ETS, ventilator reconnected to patient. The samples of arterial blood were withdrawn (from radial artery canola) before hyperinflation (control), before and after ETS, and 30 seconds after suctioning. According to statically analysis ETS after hyperinflation results in PaO2 reduction and PaCo2 elevation. This results were significant (p=.001). It is needed to study more and find out the procedure that not creating problem in critically ill patients.
