If abnormal readings are detected, the system can alert both the patient and the doctor to take immediate action. This type of monitoring improves patient safety and reduces the risk of emergencies. 2. Automated Medication Dispensing Medication errors are a significant concern in hospitals. IoT-enabled medication dispensers can automate the dispensing of drugs, ensuring that patients receive the correct medication at the right time. These systems can also track medication adherence, reducing the risk of under- or over-medication. Example: In a smart hospital, IoT-enabled medication cabinets ensure that only authorized personnel can access specific medications. When a nurse scans their ID badge, the system verifies the prescription and releases the correct medication, minimizing human error. 3. Smart Surgical Equipment In the operating room, IoT-enabled surgical tools can track their usage, monitor the health of the equipment, and even guide surgeons during procedures. Smart surgical instruments can provide real-time data on a patient’s condition, helping doctors make more informed decisions. Example: A surgeon performing a complex operation can use IoT-enabled tools that provide real-time feedback on tissue condition or tool positioning. This data can help ensure greater precision, reducing the risk of complications. 4. Smart Facility Management IoT isn’t just for patient care; it also plays a crucial role in the day-to-day operations of the hospital. Smart HVAC systems, lighting, and even beds can all be connected to an IoT network, optimizing energy use and ensuring that hospital resources are used efficiently. Example: A smart hospital uses IoT-connected sensors to monitor room temperature and air quality, automatically adjusting settings to ensure optimal conditions for both patients and staff. Additionally, maintenance alerts are sent automatically if any equipment needs servicing, preventing breakdowns. 5.
