Safety Precautions for Using the Equipment
Venous pulsations may cause erroneous low readings (e.g. tricuspid value regurgitation).
Loss of pulse signal can occur when:
The sensor is too tight.
The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.
There is arterial occlusion proximal to the sensor.
The patient is in cardiac arrest or is in shock.
The pulsations from intra-aortic balloon support can be additive to the pulse rate on the oximeter pulse rate
display. Verify patient's pulse rate against the ECG heart rate.
Misapplied sensors or sensors that become partially dislodged may cause either over or under reading of actual
arterial oxygen saturation.
Avoid placing the sensor on any extremity with an arterial catheter or blood pressure cuff.
High intensity extreme lights (including pulsating strobe lights) directed on the sensor may not allow the Pulse
CO-Oximeter to obtain readings.
The Pulse CO-Oximeter can be used during defibrillation, but the readings may be inaccurate for up to 20
seconds.
Before use, carefully read the sensor's Directions for Use.
Tissue damage can be caused by incorrect application or use of a sensor, for example by wrapping the sensor
too tightly. Inspect the sensor site as directed in the sensor's Directions for Use to ensure skin integrity and
correct positioning and adhesion of the sensor.
The Pulse CO-Oximeter is NOT intended for use as an apnea monitor.
To avoid cross contamination only use Masimo single use sensors on the same patient.
Unless otherwise specified, do not sterilize sensors or patient cables by irradiation, steam, autoclave or ethylene
oxide. See the cleaning instructions in the directions for use for the Masimo re-usable sensors.

Monitoring
(HCP-800/HCP-810, HPD-800/HPD-810)
Only one of either HCP-800/HCP-810/HPD-800/HPD-810 can be connected.
When using a sampling line for intubated patients with a closed suction system, do not place the airway adapter
between the suction catheter and endotracheal tube. This is to ensure that the airway adapter does not interfere
with the functioning of the suction catheter.
To prevent cross-infection, do not allow the sampling gas to return to the breathing system.
To protect the hospital staffs from unnecessary anesthetic agent when using the HCP-800/HCP-810, it is
strongly recommended to connect the exhaust hole to the gas exhaust system in the hospital.
Loose or damaged connections of the sampling line may compromise ventilation or cause an inaccurate
measurement of respiratory gases. Securely connect all components and check connections for leaks according
to standard clinical procedures.
Do not cut or remove any part of the sampling line. It could lead to erroneous readings.
If too much moisture enters the sampling line (i.e., from ambient humidity or breathing of unusually humid air)
when using the HCP-800/HCP-810, <Check Sample Line> will be displayed in the message area. Replace the
sampling line once this message is displayed.
Carefully route the sampling line to reduce the possibility of patient entanglement or strangulation.
Do not lift the HCP-800/HCP-810 by the sampling line, as the sampling line could disconnect from the
equipment, causing the equipment to fall on the patient.

readings and respiratory rate can be affected by sensor application errors, certain ambient environmental
conditions, and certain patient conditions.
