Cautions
Equipment may be damaged or cease to function properly if the items in this
Cautions section are not followed.
CAUTION:
• When administering anesthetic agents, incorrect agent
identification may occur when a mixture of two or more
anesthetic agents occurs in the sample circuit.
• Always verify your vaporizer setting when administering
anesthetic agents.
• Use only original Spacelabs Medical sampling lines and
accessories; other sampling lines may cause inaccurate
readings and malfunctions.
• The diameter of the scavenging system line must be two to
three times larger than the sample line tubing to avoid
changes in the operating pressure of the monitor, and
consequential inaccurate readings or internal damage.
• Route the scavenger hose so that it does not kink during
operation of the monitor. A kinked or partially kinked
scavenger hose can impair performance of the monitor.
• If the patient’s airway is configured with a closed
suctioning system, the airway adapter must be placed near
the suctioning system (on the ventilator side). This helps
to ensure that the sampling adapter is not impaired during
and after suctioning.
• Do not use cellular phones or other wireless
communications equipment near the analyzer.
!
• Check the disposable water trap regularly during monitoring.
Replace the water trap when full.
• Between patients, replace the sampling line and check the
disposable water trap. Replace the water trap when full.
• The Spacelabs Medical sampling lines are for single-patient
use only. Cleaning deteriorates the properties of the sampling
line, resulting in slower response time and more frequent
occlusions
• Before you administer nebulized drugs to a patient that is
connected to the multigas analyzer, you must disconnect the
sample line from the patient or stop the pump by using the
SUSPEND SAMPLING key.
• To facilitate disconnecting and reconnecting the sample line,
use a T-connector in the patient airway circuit and keep the
sampling suspended, until all nebulized drugs have cleared
from the patient’s airway.
