• defibrillation
Dysfunctional hemoglobins such as carboxyhemoglobin,
methemoglobin, and sulphemoglobin are unable to carry oxygen.
SpO readings may appear normal; however, a patient may be
2
hypoxic because less hemoglobin is available to carry oxygen.
Further assessment beyond pulse oximetry is recommended.
Anemia causes decreased arterial oxygen content. Although SpO
readings may appear normal, an anemic patient may be hypoxic.
Correcting anemia can improve arterial oxygen content. The monitor
may fail to provide an SpO
The N-595 will display saturation levels between 1 and 100%.
The N-595 will only display pulse rates between 20 and 250 beats per
minute. Detected pulse rates above 250 bpm are displayed as 250.
Detected pulse rates below 20 are displayed as 0.
if hemoglobin levels fall below 5 gm/dl.
