Cardiac Assessment Can Be Performed Using Smartphone Application
Blood flow in a wrist artery can be assessed using a phone’s camera through a smartphone app, according to a report published on April 3, 2018.
Smartphone application works better than the conventional physical examination in the assessment of blood flow in a wrist artery for patients undergoing coronary angiography. This study will be beneficial to physicians to make decisions at the bedside. Due to the widespread availability of smartphones, it is being used as point-of-care diagnostics in clinical settings at a minimal or no cost. For instance, smartphones integrated with software or photodiode sensors along with infrared light-emitting diodes can be used to measure changes in blood flow.
A study was conducted to compare the use of a heart-rate monitoring application with the modified Allen test that is used to measure blood flow in the radial and ulnar arteries of the wrist. 438 participants were included in the study and were split into two groups; one group was assessed using the app and the other was assessed using the Allen test. When compared to the conventional method, 94% accuracy was exhibited by the smartphone app. Dr. Pietro Di Santo, lead author says that smartphones are not designed as medical devices, however, when they are used clinically, they have to be evaluated similar to all therapies and diagnostic tests. He further said, “When we designed the iRadialstudy we wanted to hold the technology to the highest scientific standards to make sure the data supporting its use was as robust as possible.”
At present, none of the regulatory bodies have certified the use of this application in healthcare. However, this study emphasizes the potential of smartphone-based diagnostics, which will help in clinical decision-making at the patient’s bedside.
