There is no doubt that pulse oximetry is one of the greatest advances in patient monitoring, it is a simple non-invasive method of monitoring the percentage of hemoglobin (Hb) which is saturated with oxygen. A pulse oximeter consists of a probe attached to the patient’s finger which is linked to the computerized unit. It displays the percentage of Hb saturated with oxygen together with an audible signal for each pulse beat, a calculated heart rate and in some models, a graphical display of the blood flow past the probe.
Audible alarms which can be programmed by the user are provided. Pulse oximeters detect the presence of cyanosis before they are noticed clinically. Its high degree of accuracy, coupled with ease of operation , pulse oximetry, or SpO2, has become the method of monitoring patients in the ICU, operating room, in out-patient facilities, triage centers or with any procedure where anesthesia is used.
Even when transporting patients under noisy conditions, for example in aircraft, helicopters or ambulances, and the audible tone and alarms may not be heard, but a waveform can be seen together with a reliable reading of oxygen saturation, thus giving a global indication of a patient’s cardio-respiratory status. Pulse Oximeters can be expensive. A good place to get new and used medical equipment at low costs is Oisto.com
