adversely affect the accuracy of the SpO2 readings.
•
Obstructions or dirt on the sensor’s red light or detector may cause a sensor failure.
Make sure there are no obstructions and the sensor is clean.
•
Any condition that restricts blood flow, such as use of a blood pressure cuff or
extremes in systemic vascular resistance, may cause a failure to determine accurate
pulse rate and SpO2 readings.
•
Hazards arising from software errors have been minimized. Hazard analysis conforms
to meet ISO14971: 2000 and EN60601-1-4: 1996. Significant levels of dysfunctional
hemoglobin, such as carboxyhemoglogin or methhemoglobin, will spawn an affection
of the accuracy of the SpO2 measurement.
•
The handheld pulse oximeter can monitor only one patient synchronously.
•
For routine equipment maintenance, please refer to the service procedures at the
associated section as indicated in the manual.
•
As to the other concerns for attention, please carefully look through the specific
chapter in this instruction.
Inaccurate measurements may be caused by:
•
Significant levels of dysfunctional hemoglobin (such as carbonyl - hemoglobin or
methemoglobin);
•
Intravascular dyes such as indocyanine green or methylene blue;
•
High ambient light. Shield the sensor area if necessary;
•
Excessive patient movement;
•
High-frequency electrosurgical interference and defibrillators;
•
Venous pulsations;
•
Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line;
•
The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia;
•
The patient is in cardiac arrest or is in shock;
•
Fingernail polish or false fingernails;
•
Weak pulse quality (low perfusion);
•
Low hemoglobin;
1.5 Electromagnetic Interference
This oximeter is designed and tested in compliance with the EMC standard, complying with
the international standard for the EMC of the electronic medical device - IEC 60601-1-2.
However, because of the proliferation of radio frequency transmitting equipment and other
sources of electrical noise in the health-care and home environments (e.g. cellular phones,
mobile two-way radios, electrical appliances) it is possible that high levels of such interference
due to close proximity or strength of a source, may result in disruption of performance of this
device.
This apparatus complies with the IEC 60601-1-2 international standard. The requirements of
this international standard are: CISPR11, GROP1, and CLASS B.
