only. Do not clean or disinfect these items. Reuse of these items may lead to inaccurate
gas measurements or patient injury.
• Verify that the patient’s breathing efforts and timing coincide with the CO
2
waveform on
the displays before completion of the patient setup.
• Always place the 3880 monitor in a well ventilated area. The calibration system
assumes that the ambient air will contain normal amounts of waveform CO
2
. If this
system is placed in an unventilated area that allows CO
2
to accumulate, the result could
be inaccurate zeroing of the CO
2
parameter resulting inaccurate patient readings.
• Use only
IRadimed approved sampling lines and accessories. Other accessories lines
may cause inaccurate readings and malfunctions. Refer to section 9.
• Do not connect the scavenging exhaust line to the patient breathing circuit. Risk of
patient cross-infection may occur.
! CAUTION
• The accuracy of the data collected is greatly influenced by the proper use, fitting and
maintenance of the sampling tubing, and nasal cannula or airway adapter. All fittings
must be fitted together securely to keep them from separating during the procedure and
to ensure proper sampling without the introduction of outside air.
• The sample-line has a filter preventing bacterium, water and secretions from entering
the module. After a long-term use, dust or other substances may compromise the
performance of the filter or even block the airway. In this case, replace the sample-line.
It is recommended to replace the sample-line when it is found leaky, damaged or
contaminated.
• Always discard the sample-line when it becomes filled with fluid. Accidental fluid ingress
into the monitor can affect the gas measurements.
• Do not block the gas exhaust port. Inaccurate gas measurements could result.
• Remove sampling line from patient airway whenever nebulized medications are being
delivered.
• Do not over-tighten the sampling line connection. Over-tightening this connection may
cause permanent damage.
NOTE
• It is recommended that the sampling line be changed after each patient use, or every 10
hours per patient.
• An internal leak may result in condensation within the system. If this is suspected,
please contact
IRadimed Technical Support.
6.3.1. Integrated CO
2
Only Option Overview
The measurement provides:
1. A CO
2
waveform (Capnogram).
2. EtCO
2
and FiCO2 values: the EtCO
2
value measured at the end of the expiration phase.
3. Airway respiration rate: the number of breaths per minute triggered from the CO
2
waveform.
