CPRGlass, The augmented reality APP that can help you save a LIFE
We have recently seen Google Glass used for MEDED purposes, from tutorials on how to do medical procedures to the Telemedicine potential (Check Surgeon, Rafael Grossman’s work in “Inside The Operating Room With Google Glass” and “How Google Glass Is Changing Medical Education”) I am part of such projects and will continue to work on these aspects but in my opinion that is not the strongest point GLASS has. In order to see the potential of glass one needs to answer the following question. What is a smartphone without the applications you install? Answer-> A simple, and mundane phone that takes pictures and video. Therefore, a smartphone’s potential is directly linked to the apps the user has installed.
Same applies to GLASS. Many people do not understand the potential of glass in healthcare and that is the reason why I decided to develop CPRGlass. With the help of Chris Vukin and Thomas Schwartz from the evermed team (which is disrupting the conventional EMR model with GLASS technology) we have developed a prototype of an application that will help anyone perform the best CPR possible in a given situation.
In a recent article published in Resuscitation Urban concluded the following “Less than one fifth of surveyed laypersons know of Hands-Only™ CPR yet only three quarters would be willing to perform Hands-Only™ CPR even on a stranger. Efforts to increase layperson education are required to enhance CPR performance” This will be the most innovative effort you will see.
Before I get to how CPRGLASS works, I would recommend for you to watch the video created by The American Heart Association with Ken Jeong Hands-Only CPR(http://www.youtube.com/watch?v=n5hP4DIBCEE )in this video, the song Staying Alive marks the pace. The goal is to do 100 compressions per minute and the rythm of the song matches this pace. In addition, the hypothesis is, that the song could also help make the situation less stressfull. (This is just a hypothesis but future trials might help with this and other questions, remember this is just the initial prototype)
THE CPRGLASS SCENARIO
1) Person walking, witnesses someone passing out (syncope)
2) Individual says “OK GLASS, CPRGLASS”
A) Instructions appear ABC (Assess Airway Breathing and Circulation)
B) “OK GLASS, No Pulse!” * An algorithm developed by Hao-Yu Wu et al at MIT demonstrate how a normal camera can detect a pulse in a person with strong accuracy. We are looking incorporate such algorithm aka (which will be open source) ”Eulerian video magnification” to CPRGLASS for 2 reasons;
1) WIll help as an innovative method to assess if the compressions are adequate
2) Will be able to tell us if patient has regained pulse if we stop compressions, possibly, instead of even having to look for a
3) This triggers the following algorithm
A) Staying Alive Music starts which will guide you to do the compressions at a rate of 100/min. (Like AHA Video)
B) Gyroscope tells you if compressions are adequate enough by moving
C) Tracks TIME of CPR initiation and # of compressions given
D) Calls 911 with your GPS based location
E) Via GPS will try to find nearest AED which information is being obtained by crowdsourcing. Ex AED4US
F) Sends Txt Msg to nearest hospital with information regarding ungoing CPR for them to get prepared
* More functions, including live hangout with ED physicians will be mentioned in a later post.
