How Do You Measure Oxygen Saturation Using Pulse Oximeter?
• Select the appropriate pulse oximeter that fits your needs. Several different types of pulse oximeters are available. The most popular are portable handheld and fingertip pulse oximeters. • Plug oximeter into grounded wall outlet if the unit is not portable. If the unit is portable, ensure sufficient battery charge by turning it on before using. • Wash hands. This will reduce transmission of microorganisms and body secretions. • Place the probe onto your finger or earlobe, and turn the oximeter on. Adequate arterial pulse strength is necessary for obtaining accurate SpO2 measurements. • Your oxygen saturation level and pulse rate are displayed in seconds on a lighted display screen. A range of 95% to 100% is generally considered normal. If your oxygen level drops below 85% you should seek medical attention. Print out readings, and/or download them onto a computer if your oximeter has this capability.
