But a pulse oximeter reading is simply an estimate. When the capacity of the lungs to transport oxygen into the blood is impaired, blood oxygen saturation declines, potentially putting our organs in danger. Pulse oximetry has become so prevalent in the healthcare world that it is often regarded as one of the five major vital signs for understanding a person’s overall health (Chan et al. According to one scientific journal, "Pulse oximetry represents a useful diagnostic adjunct for assessing the severity of obstructive pulmonary diseases" (Dalbak et al, 2015). Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen. Normal pulse oximeter readings usually range from 95 to 100 percent. Using a continuous pulse oximetry monitor can help those diagnosed with such conditions to monitor their health—one of the many reasons to have a pulse oximeter at home. The perfusion index can also be an indication of how reliable the reading from the pulse oximeter is. Anesthesiology. Residents who are unable to pass the Basic examination will not be allowed to finish their training. That's why this book is a true must read for every anesthesiology resident. Pulse oximetry is a term that frequently appears online and in news reports in connection with COVID-19. A number of factors can impair the functioning or accuracy of a pulse oximeter. (Some people who are worried they may have—or fear contracting—COVID-19, have purchased pulse oximeters with the aim of monitoring their blood oxygen levels. It is common knowledge that an attenuated and/or inconsistent wave tracing generated by pulse oximeters displayed on intensive care unit monitors is an indication that the SpO 2 reading is unreliable or may become so, i.e., increased drop outs or false transient SpO 2 changes. Normal results on a pulse oximetry reading range between 96 and 100 percent of this maximum value. If your pulse oximetry readings fall below 90 percent of maximum, you enter a clinical state called respiratory failure, characterized by inadequate oxygen supplies to your vital organs and body tissue. Normal SpO2 is usually at least 95%. Oxygen saturation is a crucial measure of how well the lungs are working.

Don't triage with a pulse oximeter; Don't deny a SOB patient O2 while waiting for an SpO2; Don't forget to document all readings and changes on the PCR. Also, it does not provide as much information on other blood gases (e.g., carbon dioxide) as do tests that directly measure the blood. The pulse oximeter is a non-invasive device that is used to measure the oxygen level in the blood. It also helps in determining changes before they are clinically apparent. The masks are designed to be breathed through and there is no evidence that low oxygen levels occur. Pulse Rate: Pulse rate is nothing but the heart rate that indicates the number of times a heart beats per minute. Supplemental oxygen or other treatments might be needed. Due to the high importance placed on our everyday blood oxygen levels, it is important to understand what constitutes a normal SpO2 reading, along with average pulse rates. Today Pulse oximeter is a crucial part of every healthcare facility as well as emergency health transportation services.
