Once zeroing has completed, reconnect the airway adapter into the breathing
circuit, using the Getting Started instructions that are described earlier in this
section.
For the ISA (sidestream) CO2 module, zeroing is performed automatically by the
module by switching the gas sampling from the breathing circuit to ambient air.
This auto-zeroing is performed 1 to 3 times per 24 hours, and takes less than 3
seconds to complete. The zeroing procedure can also be initiated via the Zero Set
menu button in the Setup CO
menu, though this is not usually needed.

WARNING (ISA) – The ISA sidestream gas analyzer is intended for
use by authorized healthcare professional only.
WARNING (ISA) – Carefully route the sampling line to reduce the risk
of patient entanglement or strangulation.
WARNING (ISA) – Do not lift the ISA or the PPM3 monitor by the
sampling line as it could disconnect from the ISA or PPM3, causing
the ISA or PPM3 to fall on the patient.
WARNING (ISA) – Dispose Nomoline Family sampling lines in
accordance with local regulations for biohazardous waste.
WARNING (ISA) – Use only airway T-adapters with the sampling point
in the center of the adapter.
WARNING (ISA) – Do only use sample lines intended for anesthetic
agents if N
O or anesthetic agents are being used.

WARNING (ISA) – Do not use T-adapter with infants, as this adds 7
ml dead space to the patient circuit.
WARNING (ISA) – Do not use the ISA analyzer with metered-dose
inhalers or nebulized medications as this may clog the bacteria filter.
WARNING (ISA) – Since a successful zeroing requires the presence
of ambient air (21% O
and 0% CO
), ensure that the ISA is placed in a

well ventilated place. Avoid breathing near the ISA sidestream gas
analyzer before or during the zeroing procedure.
