Bluetooth Health Data Profile (HDP) and Android 4.0 operating system

Imagine that you are a doctor and you have a patient with a heart condition. The patient is currently at a friend’s house and is experiencing problems. His Android phone notifies him of the possible problem. You open the alert and can see your patient’s real-time heart rate, blood pressure, blood oxygen levels and other vital statistics to help you determine the next steps. You decide that your patient is in danger and send an ambulance at the touch of a button and immediately call your patient. Your patient’s location is also known thanks to the GPS on your smartphone.

This scenario is quickly becoming a reality with a recent development in technology: the Bluetooth Health Data Profile (HDP). Bluetooth HDP is a new layer on top of the Bluetooth protocol stack that specifies a standard set of instructions for medical devices. The HDP Bluetooth device securely connects and transmits data to a smartphone or other receiver. The data can then be transmitted to a central health management application used by doctors, nurses, home care providers, etc.

It is true that there are thousands of medical devices that are currently Bluetooth enabled. However, until now there has been no standard set of instructions for exchanging data. This means that each device must have its own proprietary application to communicate. HDP Bluetooth devices will be able to communicate with applications developed to support the new standard. One big benefit for consumers is that we can buy a heart monitor from one vendor and a blood oxygen meter from another. Both devices can now communicate with the health management system chosen by your healthcare provider. This is good for the consumer because it gives us choice and doesn’t limit us to a single vendor solution. We are also able to choose best-in-class hardware and software and purchase them at competitive prices.

Why do we need a standard set of instructions? Imagine if the web didn’t use a standard set of protocols and technology to render web pages? This would mean that you would need a specific browser to view a website built on technology X and another for one built on technology Y. A web browser, such as Firefox, may or may not work with all websites. Due to these standards, we can use a browser to navigate the web.

Medical device manufacturers and healthcare management software developers will be the largest consumers of this technology. With an increasingly aging population, healthcare providers must find better ways to deliver quality care to their clients and scale with the increasing number of cases. However, there are others who can also take advantage of this technology. For example, manufacturers of cardiovascular equipment could use Bluetooth HDP to receive data from a heart monitor worn by the user and send it to the treadmill they are running on. The speed of the treadmill can be increased or decreased depending on the data received from the heart monitor and the type of workout. The heart monitor can also be used on any other treadmill in any other gym, as long as it is HDP Bluetooth enabled equipment.

The possibilities are endless for the implementation of Bluetooth HDP. Creative individuals and groups will, of course, push this technology to its limits.
