How do you know which finger pulse oximeter* is right for your use?
10 Tips to Selecting the Right Professional Finger Pulse Oximeter:
- How accurate is the oximeter and are the accuracy claims backed by evidence, e.g., published papers?
- Will the oximeter work on a variety of patients, and does your oximeter specifically list accuracy for patients with low perfusion or dark skin tones?
- Can the oximeter handle a rugged environment? Will it still work after multiple drops and exposure to liquids?
- Will one device work for different patient size ranges, including very small pediatric up to large adult fingers, thumbs or toes, or will you need to buy two separate oximeters?
- Find out who offers the best warranty and has the best reputation for excellent customer service.
- Where is the oximeter manufactured, and who will you call if you have a problem with your oximeter?
- How long do you expect to use the oximeter? If your device doesn’t last, a lower upfront cost can result in a higher cost if you need to keep replacing it.
- Does the oximeter require calibration?
- Is the oximeter easy to use and does it have a bright LED display?
- Is the oximeter lead free?
A finger pulse oximeter is a valuable tool in any situation where a fast and accurate reading of blood oxygen saturation and pulse rates are needed. Finger pulse oximeters are intended for use by health professionals. Download this comparison chart to learn more about the durability, accuracy, and range of top finger pulse oximeters.
Test In Motion
A study comparing performance of a Nonin Medical finger pulse oximeter with PureSAT® technology and a CHOICE MMED finger pulse oximeter was conducted at a leading hypoxia research laboratory in a challenging condition: motion. Performance was determined using an industry standard breathe-down protocol of induced hypoxia in thirteen subjects. SpO2 values are compared to the gold standard which is CO-oximetry analysis of arterial blood samples. Motion was generated using a mechanical fixture with tapping and rubbing. Download a summary of the study to see the results.
Three finger pulse oximeters and one tabletop pulse oximeter were attached to a subject who was breathing for the first minute using a commercially available rebreather to induce hypoxia. The chart below illustrates that over the course of the test; only the Nonin Onyx and Nellcor pulse oximeters accurately tracked the subject’s desaturation down to 81-82% SpO2 and back up to 96% SpO2. See the Difference in this performance comparison video.
*A pulse oximeter is a noninvasive medical device used for measuring a patient’s oxygen level in the blood and pulse rate. These are important vital signs, and accurate readings are crucial.
