Today, the diagnostic method involves the use of stethoscopes, imaging (x-ray, CT), spirometry, blood and/or sputum tests for the identification of respiratory problems. However, these techniques are subjective, expensive, time taking, and inaccurate.
ResAppDX-EU: An instant, easy to use Diagnostic Tool for Respiratory Diseases
ResAppDX-EU is an innovative mobile software-only tool used for the diagnosis of Lower respiratory tract infections in infants and children. It works on the principle of ResAppâs technology which is initially invented by Associate Professor Udantha Abeyratne at The University of Queensland. ResAppâs technology utilizes an artificial intelligence technique and constructs highly precise algorithms to diagnose and evaluate the acuteness of various chronic and acute respiratory diseases like pneumonia, asthma, bronchiolitis and chronic obstructive pulmonary disease (COPD). ResApp is an automated approach, in which the diagnosis is entirely based on the analysis of a patientâs audible sound of the cough, without the need for human interpretation or additional software.

Key features of this instant diagnostic tool include
- differentially diagnosis of respiratory disease,
- use of signatures in cough and breathing sounds,
- ability to comprehend new diseases from the new clinical dataset,
- use of additional accessories eliminated.
Significance of CE Mark certification
The CE Mark signifies that ResAppDX-EU complies with all the mandatory criteria of European Unionâs (EU) regulation to be classified as Class IIa medical device and allowing it to be sold in European Economic Area (EEA).
The authorization of CE Mark for ResAppDX-EU was well backed by collecting and analyzing the data from a clinical study namely Breath-Easy Pediatric clinical study conducted at Joodalup Health Campus, Perth, Australia and Princess Margaret Hospital, Perth Australia. The Breathe Easy study is double-blind, multicentric prospective study that determined the efficacy of this programmed cough-sound centric detection method to identify the common respiratory tract disorders in children. The data was collected and investigated from 585 patients with the age group between 29 days to 12 years. The study revealed spot on identification of common pediatric respiratory disorders in children by using this mechanized cough-sound analysis. The data further indicates that ResAPPâs unique and innovative technology excellently corresponds to the presently used standard-of-care clinical diagnosis. These results are recently been published in Respiratory Research, a peer-reviewed journal. The registration number of this trial is ACTRN12618001521213 and was listed in AU and NZ Clinical Trial Registry on 11th August 2019.
