The signal separation also serves other purposes: a plethysmograph waveform "pleth wave" representing the pulsatile signal is usually displayed for a visual indication of the pulses as well as signal quality, and a numeric ratio between the pulsatile and baseline absorbance "" can be used to evaluate perfusion.

Oxygen saturation levels are an indicator of oxygen transportation in the body and point to whether oxygen is being supplied to the body, especially to the lungs in sufficient amounts. Matthes K 1935. Portable, battery-operated pulse oximeters are also available for transport or home blood-oxygen monitoring. A good guide to help understand this is the oxyhemoglobin saturation curve. fusion-header-layout-v2. It's important to know that saturation is a measure of the percent of rbcs which are carrying oxygen saturated. admin-bar. fusion-top-header. The oxygen levels in your blood tend to remain relatively consistent, even during exercise and sleep. layout-boxed-mode. Sure, in some patients you can use SpO2 as a guide, but it doesn't always reflect what's actually going on in the blood, such as in cases of patients with septic shock. com. side-header-right.。 。 。 。 。 。 。
