CAUTION
Allowing dust, fluids or foreign objects to enter the Capnometer can cause permanent
damage to the device.
With the door open, attach a suitable patient airway adaptor (cannula) to the Capnometer socket of the
Capnometer. An adult nasal cannula is typically supplied but a range of cannulas and other adaptors are
available. Twist the cannula clockwise to insert and counter clockwise to remove. When inserting, ensure
the cannula is fully inserted by twisting it until it is finger-tight.
CAUTION
Always ensure the cannula is fully inserted and fully tightened. Failing to tighten the cannula
may result in the sample being diluted and an artificially low reading being produced.
CAUTION
Below the hole for the cannula inlet is a small hole for the Capnometer exhaust. Take care
not to block this hole (an error will be caused if it becomes blocked) and ensure that dust,
fluids or foreign objects do not enter it. Note that the Capnometer is not suitable for
connection to a gas scavenging system.
Attach the cannula or airway adaptor to the patient following the instructions printed onto the pack of the
adaptor. The Capnometer will start as soon as the probe is attached to the patient.
Applying a FilterLine set
The FilterLine set is intended for the CO
2
monitoring of intubated patients.
Before attaching the airway adapter to the breathing circuit, verify that the adapter is clean, dry and
undamaged. Replace if necessary.
Place the airway adapter at the proximal end of the airway circuit between the elbow and the ventilator
circuit wye. Do NOT place the airway adapter between the ET tube and the elbow as this may allow patient
secretions to accumulate in the adapter.
If pooling does occur, the airway adapter and sampling line must be replaced.
Applying a Smart CapnoLine oral/nasal cannula
The oral/nasal cannulas are intended for monitoring CO
2
in non-intubated patients.
Oral/nasal sampling cannulas are especially valuable for patients who are prone to mouth breathing, since
most (if not all) of the CO
2
is exhaled through the mouth. If a standard nasal CO2 sampling cannula is used
on such patients, the ETCO
2
values and capnogram displayed will be substantially lower than the actual CO
2
levels present in the patient’s expired breath.
Remove the cannula from the package. Verify that the cannula is clean, dry, and undamaged.
Replace if necessary.
6.4.2 Taking readings
Place the oral/nasal cannula onto the patient with two hands by first placing the prongs of the cannula into
the patient’s nostrils, then extend the lengths of the cannula around both sides of the patient’s face routing
the cannula tubing up to and then over both the patient’s ears.
Proceed to loop the tubing around the back of the ears and bring the tubing under the ears and back
towards where the patient’s chin and throat meet.
Holding the tubes together with one hand under the chin, slide the collar around the cannula up so it secures
both tubes of the cannula together firmly but comfortably under the patient’s chin
CAUTION
Dispose of Microstream ETCO
2
consumables according to standard operating procedures or
local regulations for the disposal of contaminated medical waste.
