While the device is doing this, the readings will keep fluctuating until it stabilizes. Some people require a longer time for the pulse oximeter to optimize its sensitivity. after you insert your finger and turn the power button on, please wait about 30 seconds for the readings to stabilize. Usually, the top number is the oxygen level and the bottom number is the pulse/heart rate.įollowing are some tips that will help you get accurate readings when using the pulse oximeter:
Hi Carla! For your information, the pulse oximeter registers your blood oxygen level and your pulse/heart rate. If it reads 95/24 what does that mean I’m not understanding the bottom number could you help me out In general, the height of the pulse bar graph should be at least 30% when a reading is taken. The height of the pulse bar graph correlates to pulse strength. It is a useful feature used to determine the reliability of a reading. Pulse bar graph is a visual representation of your pulse beat. In general, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. The normal pulse rate values for adults typically range from 60-100 bpm (beats per minute). Your PR reading is a measure of the number of times your heart contracts per minute.
People who live at high altitudes may display lower SpO 2 readings. A reading of 94% or less (at sea level) suggests that your blood oxygen saturation level is low. According to Mayo Clinic, an SpO 2 reading of 95% or more is generally considered to be a normal blood oxygen level*. Your SpO 2 reading is a measure of the amount of oxygen in your blood.
