Summary

The Bennett 7200 ventilator's "100% O2 suction" feature has significant lag and recovery times, potentially failing to prevent hypoxemia during tracheal suctioning. Delivered tidal volume also decreases during this function.

Area of Science:

  • Mechanical Ventilation
  • Respiratory Care
  • Critical Care Medicine

Context:

  • Tracheal suctioning is a common procedure for mechanically ventilated patients.
  • Hypoxemia is a significant risk during suctioning.
  • The Bennett 7200 microprocessor ventilator features a dedicated "100% O2 suction" mode.

Purpose:

  • To evaluate the actual performance of the "100% O2 suction" function on the Bennett 7200 ventilator.
  • To determine the lag and recovery times of the 100% oxygen delivery.
  • To assess the impact of this function on delivered tidal volume.

Summary:

  • Four Bennett 7200 ventilators were tested. Mean lag times ranged from 20.1 to 103.3 seconds, and mean recovery times ranged from 33.0 to 134.6 seconds.
  • These times varied based on initial tidal volume, ventilator rate, and fractional inspired oxygen settings.

Related Experiment Videos

  • Delivered tidal volume was reduced when the "100% O2 suction" mode was active, falling below preset levels.

    • Impact:

    • Findings indicate the "100% O2 suction" function may not reliably prevent suction-induced hypoxemia due to delays.
    • Clinicians must consider these performance variations when using this feature for hyper-oxygenation and hyper-inflation.
    • This study highlights the need for careful application of ventilator settings during tracheal suctioning to ensure patient safety.
