Mindray VS-900 - CO Display; Measuring CO

11-2
Measurement accuracy may be affected by the breath rate and inspiration/expiration
ratio (I: E ratio) as follow:

EtCO
2
value is within specification for breath rate ≤ 60 bpm and I/E ratio ≤ 1:1;
 EtCO
2
value is within specification for breath rate ≤ 30 bpm and I/E ratio ≤ 2:1.
Measurement accuracy is unspecified for breath rate larger than 60 bpm.

CAUTION
 Eliminate the exhausted gas before performing the measurement.
 Connect an exhaust tube to the gas outlet connector of the monitor to vent the
calibration gases to a scavenging system.
 Check that the alarm limit settings are appropriate before taking measurement.
To measure CO
2
, follow this procedure:
1. Select the appropriate sampling line according to the patient category.
2. Connect the sampling line to the gas sampling port of the mini water trap by
clockwise turning.
