- Wearable devices provide patients with a convenient and non-invasive way to monitor their health from the comfort of their homes. This is especially beneficial for individuals who may have difficulty visiting a healthcare facility regularly.
Remote Monitoring in Healthcare
Remote monitoring involves the use of IoT devices and technologies to track a patient’s health status without requiring them to be physically present at a healthcare facility. This technology has been particularly valuable in managing patients with chronic diseases, the elderly, and individuals living in remote or rural areas where access to healthcare may be limited.
Types of Remote Monitoring Devices
- Smart Scales:
- Smart scales, such as the Withings Body+, allow patients to track their weight, body mass index (BMI), and other vital metrics. This data can be automatically uploaded to cloud platforms for doctors to review and provide guidance on weight management or nutrition.
- Wearable Vital Sign Monitors:
- Devices like the Philips Biosensor or VitalConnect patches allow patients to wear sensors that continuously monitor vital signs such as heart rate, respiratory rate, blood oxygen levels, and body temperature. This data is transmitted to healthcare providers for real-time monitoring and intervention when necessary.
- Home Monitoring Kits:
- Home monitoring kits, which include devices like digital thermometers, blood pressure monitors, pulse oximeters, and glucose meters, allow patients to check their health metrics at home and send the results to their healthcare provider.
