Product type
A fingertip pulse oximeter is a non-invasive medical device used to measure the oxygen saturation level in a person's blood and their pulse rate. It typically consists of a small clip-like device that attaches to a fingertip and uses light sensors to detect the color of the blood, which changes based on oxygen levels. This device is commonly used in clinical settings, at home, and during physical activities to monitor respiratory function and overall health.
| Measurement range for SpO2 | 70% to 100% |
| Measurement range for pulse rate | 30 to 250 beats per minute |
| Display type | LED or OLED |
| Battery type | AAA or rechargeable lithium-ion |
| Weight | Typically under 100 grams |
| Operating temperature | 10°C to 40°C |
When selecting a fingertip pulse oximeter, consider the accuracy and reliability of the device, especially in clinical settings. Look for models that provide clear digital displays and have features such as adjustable brightness. It's also important to check the battery life and whether the device is portable for convenience. When requesting a quote, specify any required certifications, such as FDA approval, and inquire about warranty options based on expected usage levels.
