For example, some people need more oxygen when they sleep than when they are awake. The oximeter can be used to help see how much oxygen you need and when you may need it. If your oxygen level is low in the room air, you may be asked to use supplemental (extra) oxygen. However, your cells can become strained or damaged if low oxygen levels occur too many times. ![]() Having an oxygen level lower than this for a short time is not thought to cause harm. Most people need an oxygen saturation level of at least 90% to keep their cells healthy. Having a very low level of oxygen in your blood can also put pressure on your heart and brain. Oxygen is the “gas” that gets your body “in gear,” and if you’re low on “gas,” your body doesn’t function smoothly. This is important to know because when your oxygen level is low, the cells in your body may have difficulty functioning properly. If you have lung disease, your blood oxygen level may be lower than normal. The pulse oximeter digital displays were. Why is it important to monitor my blood oxygen level? This trial was designed with neither the medical nor recovery room staff aware of the oxygen saturation reading. Why is it important to measure your current oxygen level? ![]() If your home SpO2 reading is less than 90%, call your healthcare provider. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in a person’s blood. Some people with chronic lung disease or sleep apnea may have normal levels of around 90%. Pulse Oximeter Readings Chart Pulse oximeter readings normal rangeĪ normal oxygen level is usually 95% or more. Home pulse oximeters have long been used in primary care settingsmost usually for monitoring chronic lung disease and heart failure.22 Devices cost £15-35 (20-48, 17-40) when sold commercially, but substantial savings can be made on bulk purchases. The oximeter is not suitable to monitor patients continuously for long term. If the number consistently falls below this threshold, timely medical evaluation is warranted. Pulse oximeters: practicalities and cautions. The Fingertip Pulse Oximeter is intended to measure functional arterial oxygen saturation (SpO ) and pulse rate of adult, pediatric and adolescent patients in hospital, hospital type facilities, and in the home care envirorment. A SpO2 of 100% has zero effective clinical difference from a 96% reading.Īs a general rule of thumb, a person with respiratory problems who monitors their clinical condition at home will want to ensure that the SpO2 reading consistently stays between 90 and 92% or higher. Next, it is important to know when a change in the SpO2 reading becomes significant. There is no universal SpO2 number that indicates a person’s oxygen levels are healthy and ideal.įor an oximeter to be an effective tool, you will first need to know your baseline SpO2 and be aware that your baseline reading may be affected by pre-existing COPD, heart failure, or obesity.
