Question

A mechanically ventilated patient is experiencing tachycardia with decreasing oxygen saturations while the high-pressure alarm is sounding with each breath. Delivered tidal volumes are set at 600 mL. Returned tidal volumes are 300 mL. Potential causes include which of the following?

1) leaky cuff
2) partially blocked endotracheal tube
3) partially dislodged endotracheal tube
4) unplugged capnograph sensor

Answer 1

The potential causes for a mechanically ventilated patient experiencing tachycardia with decreasing oxygen saturations while the high-pressure alarm is sounding with each breath and returned tidal volumes are less than delivered tidal volumes include a leaky cuff, a partially blocked endotracheal tube, and a partially dislodged endotracheal tube.

Step-by-step explanation:

The potential causes for a mechanically ventilated patient experiencing tachycardia with decreasing oxygen saturations while the high-pressure alarm is sounding with each breath and returned tidal volumes are less than delivered tidal volumes include:

1. Leaky cuff: A leaky cuff can allow air to escape, causing a decrease in delivered tidal volumes.
2. Partially blocked endotracheal tube: A partially blocked endotracheal tube can restrict the flow of air, resulting in decreased tidal volumes.
3. Partially dislodged endotracheal tube: A partially dislodged endotracheal tube can cause air to leak, leading to insufficient delivery of tidal volumes.

These potential causes should be investigated and addressed promptly to ensure the patient's ventilation needs are met.
