Safety Information
WARNING
• Remove the airway sampling line from the patient’s airway while nebulized medications are being
delivered.
• Leakage in the breathing or sampling system may cause the displayed EtCO
2
values to be
significantly low. Always make sure that all components are securely connected.
• EtCO
2
values measured from the CO
2
module may differ from those of from the blood gas analysis.
• Route all tubing away from the patient’s throat to avoid strangulation.
• Inspect the airway adapter for a tight connection and proper operation before attaching it to the
patient.
• Squeezing or bending the sampling line during the CO
2
measurement may cause inaccurate CO
2
reading or no reading.
17.2 Preparing for Measuring CO
2
CAUTION
• Connect the gas outlet to the scavenging system when measuring CO
2
using the sidestream CO
2
module.
• To avoid blocking the airway, empty the DRYLINE II watertrap container whenever half full.
Replacing the DRYLINE II watertrap once a month is recommended.
• The watertrap has a filter preventing bacterium, water and secretions from entering the module.
Extended use could destroy the filter in watertrap and fail to stop the bacterium, water and
secretions entering the module, result in damaging the gas module and having infection risk.
NOTE
• Do not apply adult watertrap to the neonate patient. Otherwise, patient injury could result.
• To extend the lifetime of the watertrap and module, disconnect the watertrap from the module and
set the operating mode to Standby mode when CO
2
monitoring is not required.
• The emptying interval of the DRYLINE II adult/pediatric watertrap is 31 hours @ 100 ml/min, sample
gas of 37 °C, room temperature of 23 °C, 100% RH.
• The emptying interval of the DRYLINE II neonatal watertrap is 45 hours @ 70 ml/min, sample gas of
37 °C, room temperature of 23 °C, 100% RH.
17.2.1 Measuring CO
2
Using the Microstream CO
2
Module
CAUTION
• Do not apply adult watertrap to the neonate patient. Otherwise, patient injury could result.
• Connect the gas outlet to the scavenging system when measuring CO2 using the microstream CO2
module.
