![]() Repeat the steps as instructed if required by your healthcare provider or as part of your monitoring routine. Whether using a physical notebook or a designated app, keeping a record allows for effective tracking of readings over time. Step 6: Record resultsĬarefully record the obtained values and remove the pulse oximeter from the measurement site. Once the numbers on the screen cease fluctuating, take note of the displayed oxygen saturation level (SpO2 %) and heart rate (PR bpm). Step 5: Wait for stable readingsĪllow at least a minute for the pulse oximeter to provide stable readings. This positioning enhances the stability of the device, facilitating a reliable and precise reading. Sit quietly with your hand positioned below the level of your heart, keeping it motionless. Step 4: Maintain stillness and correct positioning Ensure that the nail faces upward and that the device is snug yet comfortable on the chosen site. Step 3: Secure the pulse oximeterĬlip the pulse oximeter onto the end of the selected finger, earlobe, or toe. Remove jewelry and fingernail polish from the chosen finger, as the presence of artificial nails or cold hands can impact the precision of the results. Step 2: Prepare the measurement siteīefore proceeding, eliminate any hindrances to an accurate reading. How is a Pulse Oximetry conducted? Step 1: Power on and verify batteriesīegin by turning on the pulse oximeter, ensuring that it is adequately powered with functional batteries to guarantee accurate readings¹. Moreover, it proves invaluable in determining the need for supplemental oxygen therapy or adjusting oxygen levels. During physical exams, sleep studies, or instances of distress such as shortness of breath, chest pain, or dizziness, this test aids in swift and accurate assessments. Its application spans from monitoring oxygen levels post-surgery to assessing responses to treatments or activities affecting oxygenation.įurthermore, pulse oximetry is crucial in diagnosing and treating respiratory and cardiovascular conditions. The versatility of pulse oximetry extends to various healthcare settings, including hospitals, clinics, and even home environments. Deviations from this range may signal potential lung or heart functionality issues or indicate underlying conditions like anemia, asthma, or pneumonia. This process calculates the oxygen saturation, represented as SpO2, or the percentage of hemoglobin in the blood carrying oxygen.Ī standard SpO2 range falls between 95% and 100%. This device emits two beams of light through the skin and subsequently measures the absorption of each wavelength by the blood. The pulse oximeter typically clips onto the patient's finger, earlobe, or toe, allowing for a seamless and convenient examination. Utilizing a small but sophisticated device known as a pulse oximeter, this test has become an indispensable tool in healthcare settings. Pulse oximetry, a pivotal medical test, is noninvasive and painless to gauge blood oxygen levels and heart rate.
