Pulse Oximeters

Pulse Oximeters are monitors that provide real-time measurement of a patient’s pulse rate and arterial oxygen saturation (the oxygen-carrying capacity of the blood’s hemoglobin, expressed as a percentage; normal is in the high 90’s). A disposable or reusable probe is placed on the patient’s finger (optional probes can be used on ear or tongue for some units.) The probe emits an infrared light from one side of the finger and captures the residual light that passes through the finger on the other side. The probe transmits this data to the monitor, which calculates the oxygen saturation of the blood. Used for patients with respiratory problems, and is required by law whenever a patient is under anesthesia. 

Healthdyne 950 Finger Oximeter (HE950) Weighing only 2 ounces, this unit is 2.5 inches long. It provides instant blood oximetry and pulse readings on a 3-digit LED display, and runs on 2 AAA batteries. It is commonly worn around the neck on a cord; the batteries will last approximately 12 hours when used continuously. No printer or memory functions.
