An iPhone App to Discover Cardiac Rate
Recently, an iPhone app that measures breathing rate and heart rate function is developed and it becomes more and more popular. The developer uses the iPhone’s built-in video camera to monitor the heart rate. Patients can only use iPhones to monitor their health condition with no doctors at all times.
Many doctors praise this iPhone app for its excellent feasibility. It can transmit an accurate signal of the vital signs of a patient as a professional medical equipment. Details of the new technology is reported in the paper “Physiological Parameter Monitoring by Optical Recordings with a cell phone,” published online in advance of print, the journal IEEE Transactions on Biomedical Engineering.
This app provides patients with excellent amenities. Patients do not need to take additional medical equipment everywhere. They just take their iPhones and use the apps to discover their vital signs at all times. One of the advantages of cell phone surveillance is that it allows patients to make baseline measurements at any time, build a database that could allow for better detection of disease states.
The app’s primary developer is Chon is a specialist in signal processing. He is very famous in their own fields to create algorithms that can detect the patient’s vital signs by utilizing common medical equipment. To develop this program he has developed and optimized algorithm to allow the app to collect accurate data with the iPhone’s built-in camera. As the camera’s light penetrates the skin, reflecting the pulsating blood in the finger, the application is able to correlate subtle changes in color of the reflected light of changes in the patient’s vital signs. There are a couple of colleagues who are participating this app development, including Yitzhak Mendelson, associate professor of biomedical engineering, Domhnull Gran Quist-Fraser, assistant professor of biomedical engineering, and doctoral student Christopher Scully.
To verify data accuracy, they utilize standard medical equipment to detect different types of experiment content, such as breathing, heart rate, beat of the arteries and blood oxygen. Meanwhile, a group of people use mobile phone to try the same experiment content. While all units were recorded, were the volunteers through a series of breathing exercises while their vital signs were taken prisoner. Subsequent analysis of the data showed that the Chon new smart phone screen was as accurate as the traditional devices. While this study was done on a Droid, Chon said the technology is easily adaptable to most smart phones with a built-in video camera.
In addition to this, the Chon a plan to develop a new iPhone app to monitor atrial fibrillation because ventricular arrhythmias are the most obvious symptom of atrial fibrillation and app that monitors cardiac movement inspired him. “We are developing the program now, and we have started a preliminary clinical study with colleagues at UMass Medical School to use smart phones to detect atrial fibrillation,” Chon said.
excellent app has no iPad version and they do their best to develop and optimize for the iPad. We believe that patients can detect the beating of the arteries of the iPad a few days. They have applied for a patent for this iPhone app. “Imagine a technician in a nursing home who is able to enter the patient’s room, place the patient’s finger on the camera of a tablet, and in this one step capture all their vital signs,” Chon said. “We believe there are many uses for this technology to help patients find themselves, and to help clinicians care for their patients.”
