Description:This instrument does two things: it counts the pulse rate (how fast the heart is beating) and measures how much oxygen is in the blood. Numbers appear on the face of the machine that tell the nurse the pulse rate and the percent of oxygen in the blood. The Digit Finger Oximeter is a Pulse Oximeter and Sensor in one unit providing fast, reliable SpO2, pulse rate and pulse strength measurements on patients from pediatric to adult. Its pocket-size with a large LED display, one button keypad and auto power shutdown after 8 seconds when not in use, makes it ideal for emergency, hospital or clinical environments, or for home use. The Digit Finger Oximeter is available in your choice of two color combinations.
