6 Performance Considerations
6.1 Performance Verification
Qualified service personnel are responsible for performance
verification procedures before the oximeter is used for the first
time in a clinical setting.
6.2 Oximeter Performance Considerations
There are some patient conditions that can affect the oximeter’s
measurements.

Dysfunctional Hemoglobins
Dysfunctional hemoglobins, such as carboxyhemoglobin,
methemoglobin, and sulfhemoglobin, 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 oximeter 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
SpO
2
if hemoglobin levels fall below 5 gm/dl.

Saturation
The oximeter displays saturation level between 1% and
100%.

Pulse rate
The oximeter displays pulse rate between 30 and 254
beats per minute (bpm). The sensor accuracy ranges do
not apply to pulse rates above 254 bpm.

Data update period
The data update period is two seconds typically, and 10
seconds in extreme conditions.
