Disposable Airway Pressure Manometers for Endotracheal Tube Cuff Inflation
This study aimed to assess the performance, accuracy, precision and repeatability of two single-use airway pressure manometers as a cost-effective alternative for inflation of endotracheal tubes with high-volume, low-pressure cuffs. The manometers were tested in a bench top model against a U-tube ma...

| description | This study aimed to assess the performance, accuracy, precision and repeatability of two single-use airway pressure manometers as a cost-effective alternative for inflation of endotracheal tubes with high-volume, low-pressure cuffs. The manometers were tested in a bench top model against a U-tube manometer. Eighteen units of each device were tested. Three consecutive measurements were performed at pressures of 20, 25 and 30 cmH<sub>2</sub>O each. The mean ± SD of the recorded pressures and maximum deviation from the target pressures were calculated for each device and each target pressure. For device A, the mean ± SD pressures were 19.6 ± 0.7, 23.6 ± 0.8 and 28.3 ± 0.8 cmH<sub>2</sub>O; for device B, the mean ± SD pressures were 19.3 ± 0.6, 24.3 ± 0.9 and 29.2 ± 0.67 cmH<sub>2</sub>O for target pressures of 20, 25 and 30 cmH<sub>2</sub>O, respectively. The bias for device A was −0.4, −1.4, and −1.7 cmH<sub>2</sub>O and for device B, −0.7, −0.7, and −0.8 cmH<sub>2</sub>O for target pressures of 20, 25, and 30 cmH<sub>2</sub>O, respectively. Both devices showed results comparable to those reported for commercial cuff manometers. They represent inexpensive tools that provide clinically sufficient accuracy, precision and repeatability for ETT cuff inflation between pressures of 20 and 30 cmH<sub>2</sub>O. |
