Manual Purging

15 Monitoring Airway Flow, Volume and Pressure

Adult Mode

The system automatically purges the sensor tubing every ten minutes or less, depending on system conditions. In adult mode, the system will purge both sides of the line, one at a time, during each purge cycle. The higher the pressure, the more frequent the purging. This action anticipates increased moisture migration into the sensor tubing due to the increase in circuit pressure.

Neonatal and Pediatric Modes

The automatic purge cycles used in the neonatal or pediatric mode is fixed at every three minutes regardless of circuit pressure. Only one side of the sensor tubing will be purged during each purge cycle.

Unlike the adult purge mode, the neonatal or pediatric purge mode does not use the full force of the internal pump, but rather pressurizes an internal reservoir which is used for the purge. This minimizes the pressure delivered to the ventilator circuit, but does deliver a sufficient pressure to purge the sensor tubing.

Manual Purging

Occasionally, purging may be required in between the automatic purge cycles. The manual purge may be used as often as needed. Check the orientation of the flow sensor if repeated manual purge cycles become necessary.

To manually purge, press the Purge button on the module (marked by on international versions of the module) or select Purge in the Setup Spirometry window to initiate a combined purge and zero cycle.

Gas Compensation

Temperature and the proportions of individual gases influence the flow measurement. If values seem inaccurately high or low, check that the monitor is using the appropriate gas compensation. Gas compensation can be done using either manually entered gas concentrations or gas concentrations from the gas analyzer.

N O T E If you unintentionally switch the gas compensation to the incorrect setting, the accuracy of the measured flow and volume values may be significantly reduced. The tables below show examples of incorrect gas compensation settings and the resulting inaccuracies:
