The MightySat Medical, an over-the-counter medical fingertip pulse oximeter, has received clearance from the US Food and Drug Administration (FDA) for use without a prescription, according to a press release from manufacturer Masimo.

The device is the first and currently the only medical fingertip pulse oximeter available directly to consumers without a prescription, and it includes the same technology used by many hospitals, according to the company.

Pulse oximeter use is important for patients with diagnosed breathing problems or lung diseases such as asthma, chronic obstructive pulmonary disease, lung cancer, flu, pneumonia, or COVID-19 to collect accurate data on arterial blood oxygen saturation that they can share with their health care providers, according to the company.

However, challenges of pulse oximeter use include measuring accuracy when patients are moving, measuring patients with poor circulation, and measuring patients with darker skin types. The MightySat Medical is designed to provide reliable measures of oxygen saturation and pulse rate across all patient groups, the manufacturers said. Head over to Medscape to read the full story.
