Indications for Use
The Nonin®Model 7500 Pulse Oximeter is a portable, tabletop device indicated for use in
simultaneously measuring, displaying, and recording functional oxygen saturation of arterial
hemoglobin (SpO2) and pulse rate of adult, pediatric, infant, and neonatal patients. It is intended for
spot-checking and/or continuous monitoring of patients during both motion and no-motion
conditions, and for patients who are well or poorly perfused.
Contraindication: Do not use in an explosive atmosphere or in the presence of flammable anesthetics or gases.
Warnings
Do not use this device in an MRI environment.
This device is not defibrillation proof per IEC 60601-1.
This device is intended only as an adjunct device in patient assessment. It must be used in conjunction with other
methods of assessing clinical signs and symptoms.
Oximeter readings of this device may be affected by the use of an electrosurgical unit (ESU).
Inspect the sensor application site at least every 4 hours to ensure correct sensor alignment and skin integrity. Patient
sensitivity to sensors and/or double-backed adhesive strips may vary due to medical status or skin condition.
Avoid excessive pressure to the sensor application site as this may cause damage to the skin beneath the sensor.
To avoid patient injury, use only Nonin-branded PureLight®pulse oximeter sensors. These sensors are manufactured to
meet the accuracy specifications for Nonin pulse oximeters. Using other manufacturers’ sensors can result in improper
pulse oximeter performance.
To prevent improper performance and/or patient injury, verify compatibility of the monitor, sensor(s), and accessories
before use.
No modifications to this device are allowed as it may affect device performance.
Do not use a damaged sensor. If the sensor is damaged in any way, discontinue use immediately and replace the
sensor.
