Abstract
In order to avoid microaspiration and tracheal injury, the target for endotracheal tube cuff pressure is 25 to 30 cm H2O. To assess the effect of changes in body position on cuff pressure in patients; this quasi-experimental study was conducted on 30 patients in Qazvin hospitals. Cuff pressure was measured in six consecutive positions every two hour: immediately before and immediately, 15 minutes, and two hours after change positions. Data were analyzed at a significance level of 0.05. The right and left lateral/head up 30º and 45º positions for 15 minutes and two hours increased the endotracheal cuff pressure to values above the normal range. The changes in cuff pressure were statistically significant in the mentioned positions (P < 0.001). Minding that still minimal changes in patients’ positioning can result in potentially harmful cuff pressures.
