Adding supplemental oxygen

WARNING

•• Explosion hazard—do not use in the vicinity of flammable anesthetics.

•• Oxygen supports combustion. Oxygen must not be used while smoking or in the presence of an open flame.

•• Always ensure that the device is turned on and airflow generated before the oxygen supply is turned on. Always turn the oxygen supply off before the device is turned off, so that unused oxygen does not accumulate within the device enclosure and create a risk of fire.

The S9 VPAP Tx is designed to be compatible with the following levels of supplemental oxygen:

•• up to 15 L/min for CPAP, S, T, ST, ASV and PAC modes

•• up to 4 L/min for AutoSet, VAuto, iVAPS and ASVAuto modes.

At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration will vary depending on:

•• where the oxygen is introduced;

•• the pressure settings;

•• patient breathing pattern;

•• mask selection; and

•• leak rate.

Adding oxygen may affect the trigger and cycle reliability, delivered pressure, and the accuracy of the displayed leak, tidal volume, minute ventilation and alveolar ventilation.

To add supplemental oxygen:

1.Fit the ResMed Oxygen Connector Port to the air outlet of the S9 VPAP Tx and fit the air tubing to the oxygen connector.

2.Fit the oxygen supply tubing to the port on the oxygen connector.

3.Attach the other end of the oxygen supply tubing to an oxygen flowmeter.

4.Optimize the therapy device settings first, and then add oxygen if baseline saturation remains low.

5.Titrate oxygen according to institutional guidelines.

6.Determine an initial oxygen flow rate during wakefulness. Only increase oxygen during sleep when titration of pressure is complete.
