Top 10 Applications of IoT in Healthcare
1. Remote Patient Monitoring (RPM)
IoT devices track patient vitals — heart rate, blood pressure, glucose — and send data directly to physicians.
Benefit: Early intervention and fewer hospital visits.
Example: Philips HealthSuite platform uses IoT wearables for chronic care management.
2. Smart Wearables
Devices like smartwatches and patches monitor fitness and detect anomalies such as arrhythmia.
Example: Apple Watch detecting irregular heartbeats through IoT-integrated ECG.
3. IoT-Enabled Hospitals (Smart Hospitals)
Hospitals use connected systems for patient tracking, energy management, and automated asset monitoring.
Example: GE Healthcare’s AssetPlus uses IoT sensors to monitor equipment in real time.
4. Chronic Disease Management
IoT helps monitor long-term conditions such as diabetes or COPD by collecting continuous data.
Benefit: Personalized treatment plans and better outcomes.
5. Smart Medication Dispensers
IoT-enabled pill dispensers alert patients to take medication and notify caregivers of missed doses.
6. Telemedicine & Virtual Care
IoT expands telehealth by enabling live data sharing between patients and doctors during video consultations.
7. IoT in Surgery & Robotics
Connected surgical tools provide precision and live data feedback during minimally invasive procedures.
8. Hospital Asset Tracking
IoT tags help locate critical medical equipment instantly, reducing time waste and losses.
9. Smart Ambulances
IoT-equipped ambulances transmit patient vitals to hospitals while en route, preparing ER teams in advance.
