Oximetry Considerations
Pulse Rates
The oximeter only displays pulse rates between 20 and 250 bpm. Detected pulse
rates above 250 bpm are displayed as 250. Detected pulse rates below 20 are
displayed as a zero (0).
Saturation
The oximeter displays saturation levels between 1% and 100%.
Patient Conditions
Dysfunctional Hemoglobins
Dysfunctional hemoglobins such as carboxyhemoglobin, methemoglobin, and
sulphemoglobin are unable to carry oxygen. SpO
2
readings may appear normal;
however, a patient may be hypoxic because less hemoglobin is available to carry
oxygen. Further assessment beyond pulse oximetry is recommended.
Anemia
Anemia causes decreased arterial oxygen content. Although SpO
2
readings may
appear normal, an anemic patient may be hypoxic. Correcting anemia can improve
arterial oxygen content. The oximeter may fail to provide an SpO
2
reading if
hemoglobin levels fall below 5 gm/dl.
OxiMax™ Pulse Oximetry Sensor Performance Considerations
Safety Information
WARNING
Pulse oximetry readings and pulse signal can be affected by certain ambient
conditions, sensor application errors, and certain patient conditions.
WARNING
Tissue damage can be caused by incorrect application or inappropriate duration of use
of an OxiMax pulse oximetry sensor. Inspect the sensor site as directed in the
Directions for Use.
WARNING
Use only Nellcor-approved OxiMax pulse oximetry sensors and pulse oximetry cables
when connecting to the OxiMax pulse oximetry sensor connector. Connecting any
other cable or sensor influences the accuracy of sensor data, which may lead to
adverse results.
WARNING
Failure to cover the OxiMax pulse oximetry sensor site with opaque material in high
ambient light conditions may result in inaccurate measurements.
