15 Monitoring Airway Flow, Volume and Pressure

Zero Calibration

• A volume waveform as displayed below on the left may be an indicator of an air leak:

Abnormal waveform due to leak

Normal waveform

 

In general, if MVexp or TVexp are significantly smaller than MVin or TVin, the tubing should be checked for leaks.

Zero Calibration

The zero calibration maintains the accuracy of the spirometry waves and numerics by regularly compensating for drifts within the measurement section. It is performed automatically without user interaction and takes about 2 seconds to complete. The automatic zero calibration is normally carried out every ten minutes. During warm-up or when the ambient pressure changes, this interval may be reduced to two minutes.

During the zero calibration the waveform is flat but the numerics remain on the screen. Typically, a zero calibration is started at the beginning of a respiration cycle, therefore a waveform may begin normally and then immediately become flat for the time of the zero calibration.

Zero Calibration

Automatic Purging

A double lumen connecting line (tubing) connects the flow sensors to the patient monitor. The M1014A Spirometry Module includes an automatic and manual purge feature which provides a flush of room air to keep the sensor tubing free from water condensation and patient secretions. This feature is available for the adult, pediatric, and neonatal modes. The purge will begin with the exhalation portion of the ventilator cycle.

N O T E • During the purge cycle the pump will be heard

•If the purge does not sufficiently clear the flow tubing lines, the flow sensor should be replaced

•With each purge cycle, a zero calibration is automatically performed
