Emergency Kit Finger Pulse Oximeter
A pulse oximeter is a medical device that measures heart rate and the oxygen level in the blood, expressed as the percent of oxygen saturation. Pulse oximeters operate by shining light through the skin to the blood vessels below. These devices are routinely used in many health care settings and are available over the counter. High oxygen saturation — close to 100 percent — indicates that the red blood cells are fully loaded with oxygen from the lungs.
- Dependable and easy way to spot check oxygen and heart rate levels
- A simple one-button operation
- LED display makes it easy to see your readings
- Auto power off when you remove your finger for maximum battery life
- Padded with soft silicone
- Noninvasive and does not prick
Turn on the pulse oximeter by firmly pressing the power button. The screen should light up almost instantly.
Place the sensor — the part that opens and closes like a clothespin — on any finger, with the sensor screen above the fingernail. If the sensor does not have a screen, run the cable along the back of the finger or hand. Do not use the thumb because readings are less reliable than finger readings.
Wait quietly while the pulse oximeter acquires a signal. This may take 10 seconds or more, depending on conditions. Excessive movement during measurement can decrease the accuracy of the result or may cause an error message.
Look at the display to see the heart rate, usually indicated with a heart or pulsing light. The percent of oxygen saturation is typically indicated by the symbol “SpO2.”
Leave the sensor on for continuous monitoring. If only a single measurement is required, remove the sensor and press the power button to turn off the device.
A normal percent oxygen saturation reading is in the 95 to 100 percent range. In the event of a low oxygen saturation measurement, look for signs of respiratory distress. This includes shortness of breath, wheezing, difficulty breathing or a bluish discoloration of the face, lips or fingernails. Seek medical attention right away if the respiratory distress is a new or uncomfortable symptom. If the symptom gets worse, or if the pulse oximeter measurement is below 90 percent, seek medical attention
