WARNING
Warnings alert users to potential serious outcomes (death, injury, or adverse
events) to the patient, user, or environment.
Caution
Cautions alert users to exercise appropriate care for safe and effective use of
the product.
Note
Notes provide additional guidelines or information.
1.3.2 Warnings
WARNING:
Explosion hazard — Do not use in the presence of flammable anesthetics.
WARNING:
Shock hazard — Use only when connected to a grounded outlet to avoid
electric shock.
WARNING:
Before attempting to open or disassemble, disconnect the power cord to
avoid possible injury.
WARNING:
Use only Covidien-approved internal batteries.
WARNING:
The monitoring system is not defibrillator-proof. It may remain attached to
the patient during defibrillation or during use of an electrosurgical unit,
1-2 Service Manual
however, readings may be inaccurate during use in this environment and
shortly thereafter.
WARNING:
Supplemental oxygen will attenuate patterns of desaturation. A patient’s
respiratory compromise can be proportionally more severe before patterns
appear in the saturation trend. Remain vigilant when monitoring a patient on
supplemental oxygen.
WARNING:
Do not silence or disable audible alarms or decrease the volume of the audible
alarm if patient safety could be compromised. Do not dim or disable visual
alarms if patient safety could be compromised.
WARNING:
Ensure the monitoring system is clear of any obstructions that prevent
awareness of visual or audible alarms. Failure to do so may result in
inadvertently missing a visual alarm or an inaudible alarm tone.
Safety Information
WARNING:
Do not use any monitoring system, sensor, cable, or connector that appears
damaged. Remove any damaged equipment from service for inspection by a
qualified service technician.
WARNING:
Do not lift by the sensor or interface cable. The cable may disconnect,
potentially dropping the monitoring system on a patient or damaging
surface.
WARNING:
When installing the AC power cord, ensure the cord is carefully positioned to
prevent tripping and entanglement.
WARNING:
Do not spray, pour, or spill any liquid on the monitoring system, its accessories,
connectors, switches, or openings in the chassis, since this may cause damage
to the monitoring system.

WARNING:
1.3.3 Cautions
To ensure accurate performance and prevent device failure, do not subject to
extreme moisture, such as direct exposure to rain. Such exposure may cause
inaccurate performance or device failure.
The monitoring screen contains toxic chemicals. Do not touch a broken
enclosure or monitoring screen. Physical contact with a broken enclosure or
monitoring screen can result in transmission or ingestion of toxic substances.
No user serviceable parts inside.
Caution:
Federal law (U.S.A.) restricts this device to sale by or on the order of a
physician.
Caution:
When connecting the monitoring system to any instrument, verify proper
operation before clinical use. Both the monitoring system and the instrument
connected to it must utilize a grounded outlet. Any equipment connected to
the data interface must be certified according to the latest IEC/EN 60950 -1
standard for data-processing equipment, the latest IECEN 60601-1 standard
for electromedical equipment, or the latest IEC/EN safety standards relevant
to that equipment. All combinations of equipment must be in compliance
with Requirements for Medical Electrical Systems IEC Standard
60601-1:2007and the electromagnetic compatibility IEC/EN Standard
60601-1:2005. Anyone who connects equipment to the data interface is
configuring a medical system and, therefore, is responsible for ensuring that
the system complies with the Requirements for Medical Electrical Systems
IEC/EN Standard 60601-1-1:2007 and the electromagnetic compatibility IEC/
EN Standard 60601-1-2:2007. Accuracy may degrade if it is connected to
secondary I/O devices when the equipment is not connected to earth
reference.

Caution:
Observe electrostatic discharge (ESD) precautions prior to opening the chassis
or handling any internal components.
Caution:
Observe the required torque for tightening screws. Over-tightening can strip
out screw holes, rendering them useless.

1. Saturation accuracy varies by sensor type. Refer to the Nellcor™ Oxygen Saturation Accuracy Specification Grid at
www.covidien.com/rms.
2. Accuracy specifications were validated using measurements of healthy non-smoking adult volunteers during controlled
hypoxia studies spanning the specified saturation ranges. Subjects were recruited from the local population and comprised
both men and women ranging in age from 18-50 years old, and spanned a range of skin pigmentations. Pulse oximeter
SpO2 readings were compared to SaO2 values of drawn blood samples measured by hemoximetry. All accuracies are
expressed as ±1 SD. Because pulse oximeter equipment measurements are statistically distributed, about two-thirds of the
measurements can be expected to fall in this accuracy (A
3. Adult specifications are shown for OXIMAX MAX-A and MAX-N sensors with the Nellcor™ Bedside Respiratory Patient Monitoring System.
4. Neonate specifications are shown for OXIMAX MAX-N sensors with the Nellcor™ Bedside Respiratory Patient Monitoring System.
5. Clinical functionality of the MAX-N sensor has been demonstrated on a population of hospitalized neonate patients. The
observed SpO2 accuracy was 2.5% in a study of 42 patients with ages of 1 to 23 days, weight from 750 to 4,100 grams,
and 63 observations made spanning a range of 85% to 99% SaO2.
6. Specification applies to Nellcor™ Bedside Respiratory Patient Monitoring System oximeter performance. Reading accuracy
in the presence of low perfusion (detected IR pulse modulation amplitude 0.03% - 1.5%) was validated using signals
supplied by a patient simulator. SpO2 and pulse rate values were varied across the monitoring range over a range of weak
signal conditions and compared to the known true saturation and pulse rate of the input signals.
7. Motion performance was validated during a controlled hypoxia blood study. Subjects performed rubbing and tapping
movements 1-2 cm in amplitude with aperiodic intervals (randomly changing) with a random variation in frequency between
1-4 Hz. Applicability: OXIMAX MAX-A, MAX-AL, MAX-P, MAX-I, and MAX-N sensors.
