Android based warning system for the early detection of allergic reactions

This work proposes an Android-based platform to warn the medical staff of the onset of allergy reactions during a provocation test in a hospital. The portable system carries out the analysis of the heart rate variability for the early detection of allergic reactions in patients undergoing allergy provocation tests at hospitals. The proposal is composed of an ECG (electrocardiogram) acquisition system and an Android device (Smartphone, Tablet) that monitors and evaluates the results in real time, increasing the safety of allergic tests. At present, food and drug allergic tests are a major problem for patients because of their long duration and intrusion. However, the authors have designed an algorithm for detecting allergy reactions that have focused on reducing the time of the tests and the number of doses. This algorithm runs on an Android platform, and it is able to provide alarms for the medical staff if there is an allergy reaction. The proposed monitoring system is very suitable for the health monitoring during the provocation tests.
