Maintaining an endotracheal tube (ETT) cuff pressure between 20 and 30 cm H2O helps prevent ventilator-associated pneumonia. Cuff pressures decrease over time due to many factors. Would an intervention of continuous ETT cuff monitoring with alarms help maintain the recommended pressure? Sole and colleagues studied 32 patients for 2 days (each serving as both control and intervention) and found the following:
Monitoring with intervention to add or remove air was effective in maintaining optimum cuff pressures twice as often as the control group (88.8% vs 48.3%).
The proportion of time cuff pressures were in optimum range was significantly higher on the intervention day versus the control day.
The number of interventions ranged from 2 to 14 per patient during the 12-hour intervention day.
Only small amounts of additional air (0.1–0.2 mL) were needed to maintain cuff pressure, so consider using a...
