Indications for Use
Indications for Use The Nonin® Model 2500 Pulse Oximeter is indicated for use in measuring and displaying functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate for adult, pediatric, and neonatal patients. The device is intended for continuous monitoring and/or spot-checking of patients during both motion and no-motion conditions, and for patients who are well or poorly perfused.
Contraindications Do not use this device in an MR environment. Explosion Hazard: Do not use in an explosive atmosphere or in the presence of flammable anesthetics or gasses. This device is not defibrillation proof per IEC 60601-1.
Warnings This device is intended only as an adjunct 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 6 to 8 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. To avoid patient injury, use only with 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. As with all medical equipment, carefully route patient cabling to reduce the possibility of patient entanglement, strangulation, or injury to the patient. This device should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is necessary, the device should be observed carefully to verify normal operation. The use of accessories, sensors, cables, and power supplies other than those specified in the Parts and Accessories List may result in increased electromagnetic emission and/or decreased immunity of this device. This device must be able to measure the pulse properly to obtain an accurate SpO2 measurement. Verify that nothing is hindering the pulse measurement before relying on the SpO2 measurement. Operation of this device below the minimum amplitude of 0.3% modulation may cause inaccurate results.

Pulse Quality Display The Pulse Quality display (identified by the symbol) is a tricolor LED that blinks once for each detected pulse. The Pulse Quality display changes color to indicate changes in the pulse waveform signal that may affect the SpO2 data. It may blink green, amber or red. • Green indicates a good pulse strength signal. • Amber indicates a marginal pulse strength signal. To improve signal quality, reposition the sensor, try a different sensor type, reduce patient movement, or improve the site’s circulation. • Red indicates an inadequate pulse strength signal. While the Pulse Quality display is red, SpO2 and pulse rate values are not updated. After about 10 seconds, the values are replaced with dashes, indicating that readings are not possible.
Low Battery Indicator When batteries are critically low, the digital displays will go blank, and the Pulse Quality display will blink amber or red, but not green. After 10 minutes at critically low battery capacity, the pulse oximeter will shut off automatically.
Sensor Fault or Inadequate Signal Display If the device determines that a sensor fault exists (a sensor disconnect, failure, misalignment or incompatibility with the monitor) or if a pulse oximeter sensor signal is no longer detected, a dash (-) appears in the leftmost position of the SpO2 display. The readings that are displayed will freeze for 10 seconds if the pulse oximeter sensor fault or the inadequate signal continues. If the sensor fault or the inadequate signal is not corrected, the frozen readings and the dash in the leftmost position will be replaced by dashes in the middle of both the SpO2 and the Pulse Rate displays after 10 seconds. When the sensor fault or the inadequate signal is corrected, the SpO2 and pulse rate displays will return to normal operation.

Using the PalmSAT Pulse Oximeter
Using the PalmSAT Pulse Oximeter The Model 2500 PalmSAT is a digital handheld pulse oximeter that displays numerical values for blood oxygen saturation (%SpO2) and pulse rate. This device will typically operate for 80 hours continuously between alkaline battery replacements, or for 40 hours with the Model 2500B Rechargeable NiMH (Nickel Metal Hydride) Battery Pack (optional). The device requires no routine calibration or maintenance other than replacement of alkaline batteries or recharging the optional battery pack with the Model 2500C Charger Stand (refer to the Model 2500C Operator’s Manual). The pulse oximeter determines functional oxygen saturation of arterial hemoglobin (SpO2) by measuring the absorption of red and infrared light passing through perfused tissue. Changes in absorption caused by the pulsation of blood in the vascular bed are used to determine oxygen saturation and pulse rate. Pulse Oximeter Sensor Connector
