9m Pulse Oximeter

We are esteemed manufacturer and supplier of an advanced range of 9M Pulse Oximeter in New Delhi Delhi India. Pulse oximetry is a noninvasive method for monitoring a person's oxygen saturation (SO2). Its reading of SpO2 (peripheral oxygen saturation) is not always identical to the reading of SaO2 (arterial oxygen saturation) from arterial blood gas analysis but the two are correlated well enough that the safe convenient noninvasive inexpensive pulse oximetry method is valuable for measuring oxygen saturation in clinical use. In its most common (transmissive) application mode a sensor device is placed on a thin part of the patient's body usually a fingertip or earlobe or in the case of an infant across a foot. The device passes two wavelengths of light through the body part to a photodetector. It measures the changing absorbance at each of the wavelengths allowing it to determine the absorbances due to the pulsing arterial blood alone excluding venous blood skin bone muscle fat and (in most cases) nail polish. Reflectance pulse oximetry may be used as an alternative to transmissive pulse oximetery described above. This method does not require a thin section of the person's body and is therefore well suited to a universal application such as the feet forehead and chest but it also has some limitations.
