Maintenance
Capnography Sensors
The capnography sensor and cable should be cleaned routinely, especially between patient uses.
Before cleaning, make sure the sensor is disconnected from the module and/or monitor. Sensors
and cable assemblies may be wiped down using a cloth or swab dampened in 70% alcohol or 10%
bleach solutions. Mild detergents may also be used initially to remove any residual buildup.
Sensors should be wiped immediately following cleaning with distilled water and then dried to
remove any cleaning residue.
Caution:
• Under no circumstances should sensors be immersed in a solution of any type.
• Do not autoclave the sensor.
• Never use solvents, acetone, or abrasive cleaning agents.
• Do not force the sensor onto the airway adapter.
• Avoid undue stress on the sensor head and the cable.
Note:
• After unpacking, keep the sensor container. When not in use, disconnect the sensor from
the module and/or monitor, clean, and place it into the container for safe keeping.
• Sensor exposure to cleaning agents should be limited to a maximum of 15 to 20 minutes.
Longer intervals of exposure could produce a slight dulling of the original surface finish.
Visually inspect the sensor, cable, and the airway adapters for any sign of physical damage. Verify
that the plugs and connectors are in good working condition and that the pins and prongs are not
bent. Use a cotton swab dampened with alcohol or a mild soap to carefully clean the windows of
the sensor head and the calibration cells. Always remove any damaged or questionable sensor or
airway adapter from service.
Mechanical Inspection
Verify that:
• the unit and all optional equipment are clean;
• all screws are tight;
• the case and connector pins are not damaged; and
• there are no frayed or pinched wires or cables.
Electrical Safety Testing
Safety testing protects the patient from electrical shock, especially micro-shock. It has been
determined experimentally that current values in the microampere (μA) range may cause fatal
arrhythmias in electrically susceptible patients. A patient is deemed electrically susceptible when
connected to monitoring equipment.
