Let's say you are the person wearing Glass and you see someone pass out. Saying "OK GLASS, CPRGLASS" sets things into motion. You are instructed to check ABC (Assess Airway Breathing and Circulation). If no pulse can be detected, you say "OK GLASS, No Pulse!" If you do not know how to find a pulse, Dr. Assad adds that a way to detect a pulse using a regular camera has proven to be quite accurate and that this is being written into the program.
If there is no pulse, you are guided to do CPR, ironically by following the BeeGees song Staying Alive, which guides you through compressions at a rate of 100/min. A gyroscope makes sure that you are doing the compressions correctly. The program counts the number of compressions and the tine since you started them. Using GPS, the program calls 911 with your location and a text message is sent to the nearest hospital with the nearest data about your CPR activity.
Even saving one life makes writing this app worth it. It also shows you a side of technology that gets overshadowed by other unimportant things. Yes, you can post on Instagram a picture of your lunch, but you can also save a life.
