IoT in Healthcare Market

What is IoT in Healthcare?

IoT technology in healthcare connects medical devices such as insulin pumps, wearables, and sensors to the internet for hassle-free data sharing. These devices gather a patient’s real-time health metrics and transfer them to healthcare providers to automate care. But what’s the importance of IoT in healthcare? What purpose does it solve?  

Well, to answer the above question, we will take an example. 

Suppose an elderly patient with chronic heart disease wears a smart patch that regularly monitors heart rate, blood pressure, and oxygen levels. This data is then automatically sent to their doctor’s system. If the patch detects a sudden drop in oxygen or a heart rate spike, the system instantly alerts the doctor. The doctor can then remotely assess the patient and intervene before a severe crisis occurs.

This presents the significant impact of IoT in healthcare with proactive and real-time monitoring. Additionally, it reduces hospital readmissions and allows for personalized, timely interventions. Ultimately, IoT for healthcare improves patient outcomes and quality of life.

How Does Internet of Things in Healthcare Work?

As we have discussed the role of IoT in healthcare, it’s also necessary to know how it functions. Understanding the functionality will give you a clear picture of how IoT connects medical devices and provides seamless communication between patients and healthcare providers.

There are various IoT devices used in healthcare (like glucose monitors or pulse oximeters) to gather patient data. This data then travels through Wi-Fi, Bluetooth, or 5G to cloud platforms. AI algorithms analyze trends, flag risks, and alert doctors. For example, a smart inhaler tracks asthma triggers and sends alerts to an IoT-powered healthcare mobile app that prompts patients to take necessary precautions. 

IoT implementation in healthcare processes includes many key steps. The essential steps are discussed below:

1. Data Gathering 

IoT medical devices gather complete healthcare data from patients by continuously monitoring them 24/7.
