A finger pulse oximeter measures oxygen saturation level in the body without using needles or taking a blood sample. The metric shown on the screen (or the BodiMetrics App) reflects red blood cell oxygen saturation. The percentage gives doctors and medical advisors an indication of whether a person is within normal range on a blood oxygen meter or pulse ox level. Oxygen level may also help to determine if you require supplemental oxygen. The saturation number (a normal pulse ox number would be over 90-92%) is often referred to as SpO2.
Finger Pulse Oximeter
A finger oximeter is a simple, nonintrusive way to track blood oxygen saturation. The advantage of tracking blood oxygen using a mobile phone App is that you have historical data to see your SpO2 levels over time. See more about BodiMetric’s finger pulse oximeter ring here.
A wearable pulse oxygen meter is extremely helpful when monitoring oxygen levels throughout the day, during exercise, and at night during sleep. A sleep oxygen monitor is invaluable for helping individuals with sleep breathing issues (like sleep apnea). During sleep monitor oxygen levels and track them the next morning and over time. A blood oxygen sleep monitor allows the user to see trends that may affect their sleep. Using a comfortable oxygen sensor like a ring, ensures that the device itself is not causing additional sleep or comfort problems.
For respiratory illnesses, a lower than expected blood oxygen level (SpO2) may be an early indicator. If an unexpected drop in blood oxygen occurs, it may be a sign to seek medical attention. During the COVID-19 pandemic, studies have shown that patients may have low blood oxygen prior to other symptoms. Data collected from technology may be sent to medical professionals, often referred to as eHealth or Telemedicine. Doctor’s and nurses can help diagnose potential conditions remotely using cloud applications and data sharing.
