Finger Pulse Oximeter Heart Rate SPO2 Blood Oxygen Meter Monitor

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 reliably enough correlated that the safe, convenient, noninvasive, inexpensive pulse oximetry method is valuable for measuring oxygen saturation in clinical use.The fingertip pulse oximeter model CMS-50DL is designed to provide an accurate, yet affordable, way for spot-checking blood oxygen saturation levels and pulse rate. A blood-oxygen monitor displays the percentage of blood that is loaded with oxygen. More specifically, it measures what percentage of hemoglobin, the protein in blood that carries oxygen, is loaded. Acceptable normal ranges for patients without pulmonary pathology are from 95 to 99 percent. This oximeter is designed for sports and aviation use mainly. Comes with a free carrying case and lanyard, this is
