Gas Monitoring with Gas Module 3

Operations

WARNING: When using the Gas Module 3, the maximum sampling rate at the nasal cannula is 200 ml/min with an Adult/Pediatric water trap and 120 ml/min with a Neonatal water trap. This device should not be used on patients whose breathing could be impaired by this vacuum flow rate. NOTE:

The Gas Module 3 is equipped with automatic barometric pressure compensation.

NOTE:

The Gas Module 3 uses a fixed correction of 11 hPa to compensate for the influence of water vapor in the gas sample, when converting the gas readings to ATPD. An increase in the ambient H20 partial pressure to 30 hPa (i.e. 28 °C, 80% RH or 33 °C, and 60% RH) will cause a general error for all gases of only -2% REL.

Monitoring Anesthetic Gases, O2, N2O and/or CO2 NOTE:

To prevent moisture from entering the pneumatic system, ensure that the Gas Module 3 is always installed and operated in the horizontal orientation shown in all graphical depictions.

1. Turn on the Gas Module 3 and the bedside monitor, and configure the bedside monitor serial port to be used with the Gas Module. Hold the DISCHARGE key in while powering unit on. Set alarms as desired.

Operations

Gas Monitor Calibration - Passport 2®/Spectrum®/Spectrum OR™ Accuracy verification of the Gas Module 3 is recommended at one (1) year intervals or whenever gas readings appear to be in error. The date of the last successful mixture calibration appears at the bottom of the gas Calibration Menu. During the calibration session gas readings and all other gas functions are not available. Span calibration is a set of prompted commands that enables the operator to align the gas display(s) to specific gas concentration(s) within the Datascope Calibration Gas canister. Span calibration can be initiated by the operator any time the gas module’s readings are suspected to be inaccurate. Always verify accuracy using a full canister of Datascope approved precision calibration gas, after calibration is performed. Never use calibration gas that has expired, has a different concentration, or a canister that is indicating low pressure. The pressure indicator on the Datascope gas regulator must operate in the green zone during the entire calibration session. NOTE:

2.1.2.1

The Gas Module 3 must be fully warmed up before performing a gas calibration. For maximum accuracy, a warm-up time of 10 minutes is recommended.

Passport 2®/Spectrum® 1. Select Calibrate from the Gas Menu. The Calibration Menu opens. 2. Select Gas Selection from the Calibration Menu and choose the calibration gas type.
