Asthma is a chronic respiratory disease that affects millions of people worldwide, in fact 25 million people in America alone suffer from asthma (Asthma & Allergy Foundation, 2022). A study published in the Journal of Asthma and Allergy found that using a wearable device to monitor asthma symptoms improved patient outcomes and reduced the number of emergency room visits. By providing real-time data on blood oxygen saturation levels and other vital signs, these devices can help patients manage their asthma symptoms more effectively and prevent serious complications (NIH, 2015). 

Using the OxyKnight® Watch with AsthmaGo™ can be particularly useful for asthma patients, as it can alert them when their blood oxygen saturation drops below a certain level. While this shouldn't be confused with being an indicator of an upcoming asthma attack or any acute symptoms, it can help asthma patients monitor the effectiveness of medications or treatments and lung damage over time. The OxyKnight® Watch is a smartwatch that tracks blood oxygen levels, heart rate, and other vital signs in real-time using continuous monitoring. The OxyKnight® Watch provides a simple and non-invasive way to assess the severity of asthma symptoms and adjust treatment accordingly.  

Disclaimer: Always talk to a doctor about if and when it is right for you to use an oximeter, and what your ideal oxygen saturation range is. Oximeters are not meant to be a sole diagnostic tool. You should always consult with your physician about results, medications, and treatment plans.
