Pulse Oximeters are a non-invasive way to measure the oxygen saturation of a patient's blood and pulse rate. In emergency medical care, pulse oximetry is a vital way to detect hypoxemia. It typically uses either a photoelectric unit or sensor that attaches to the finger, toe, or ear. Pulse Oximetry sensors can be disposable or reusable depending on provider preferences. QuadMed has Pulse Oximetry equipment from top brands like Masimo, Nonin, or Smiths.
