With the data available through a smartphone app, patients can manage their condition more effectively, while doctors can track trends remotely, adjusting treatments accordingly. 3. Respiratory Monitoring Wearable respiratory monitors are another breakthrough for patients with chronic obstructive pulmonary disease (COPD) or asthma. Devices like the Spire Stone track respiratory patterns, stress levels, and activity. By providing real-time feedback, these wearables help patients manage their breathing patterns more effectively and allow healthcare providers to monitor respiratory health remotely. 4. Sleep Monitoring Wearables have also made significant strides in sleep medicine. Devices like the Oura Ring or the Whoop Strap track not just how long a person sleeps, but also the quality of their sleep. They monitor various stages of sleep (REM, deep, and light), heart rate variability, and body temperature, providing comprehensive insights into a patient's overall health. This data can be crucial for diagnosing sleep disorders such as sleep apnea and for promoting better sleep hygiene. 5. Wearables in Elderly Care Elderly care has seen a particular benefit from wearable health technologies. Devices like the Lively Mobile Plus act as a combination of a health tracker and a medical alert system, allowing older adults to live independently while giving their caregivers peace of mind. These wearables can detect falls, track movement, and monitor vital signs, ensuring that seniors receive immediate medical attention when needed. Advantages of Real-Time Patient Monitoring 1. Early Disease Detection Wearables provide continuous data that can reveal early warning signs of potential health issues before they become severe. For example, a sudden increase in heart rate or changes in blood oxygen levels could indicate an impending cardiac event, prompting early medical intervention. Similarly, irregularities in glucose levels detected by a CGM can help prevent dangerous blood sugar fluctuations in diabetics. 2. Personalized Treatment The data collected by wearables allow doctors to provide highly personalized treatment plans based on the patient’s real-time physiological information. This level of customization is impossible to achieve with occasional office visits and traditional monitoring tools. 3. Increased Patient Engagement Wearables encourage patients to take an active role in managing their health. Many patients become more mindful of their behavior, including diet, exercise, and sleep, when they can visualize their progress and see how lifestyle changes impact their health metrics. This increased engagement can lead to better overall health outcomes. 4. Remote Patient Monitoring One of the greatest advantages of wearable health tech is its ability to support remote patient monitoring (RPM). Especially during the COVID-19 pandemic, RPM became essential for minimizing in-person visits while still delivering quality care. Devices like Fitbit Health Solutions and BioIntelliSense BioSticker provide physicians with accurate, real-time data that they can use to monitor and treat patients from afar. 5.
