Measurement of EtCO2
11.1 EtCO2 Measurement (Optional)
Sidestream CO2 Gas Measurement
Sidestream CO2 module can be fitted onto BT-750. Sidestream CO2 provides the function of
ETCO2 and the function to measure respiratory CO2 and respiration numbers using the small
filterline based on a small lumen type filterline. In the Sidestream CO2 type, the level is
measured through the cannula (non-tubing type) attached to the nose or a sampling line
equipped in the respiratory circuit (tubing type).
Caution
The maximum sampling rate of the nose tube is 50mL/min. The
product should not applied to patients who may experience
respiratory distress by the vacuum flow level.
To prevent infection of the medical staff by the patient’s respiration
sample, the outlet of BT-750 should be connected to the air
elimination system of the hospital.
Caution
The gas inspiring vacuum pressure (negative pressure) of the gas
elimination system should not exceed the pump outlet standard of
BT-750, 1mmHg. Excessive pressure will display the message of
“OCCLUSION” and it may damage the BT-750 product pump.
During zeroing, the air elimination system should be operating.
Waste from Microstream and CO2 filter should be treated as fatal
biological materials for the human body
Note
Connection of all tubes should be safe, and the nose cannula should
be kept away from the CO2-present area during the self test period
(including the outlet of the ventilator and the respiration of the user).
Range of Respiration Measuring : 0 ~ 150bpm
For the best accuracy, a warm-up of about 2 minutes is required.
Note
We do not use specific gas for calibration and manually operate “O”
Calibration.
When you adjust “O” calibration, connect it to the transducer and
monitor in the air. The patient may not connect it to the other gas.
Operate “
Menu → ZERO → YES” in order .
Use it after verifying “O” value at the window screen, otherwise the
measurement value would not be correct.
