electronRx will launch its pDx app at the HLTH 2025 conference in Las Vegas in October, offering patients with chronic respiratory diseases the ability to measure lung function at home using everyday devices such as a mobile phone, laptop or tablet.

The technology allows clinicians to remotely assess cardiopulmonary function, monitor disease progression and adapt treatment plans. By reducing the need for frequent hospital visits, the company said the tool could ease pressure on health systems while giving patients greater control over managing their condition.

The pDx app builds on electronRx’s earlier purpleDx platform, expanding access to laptops and tablets in addition to mobile phones. It adds questionnaires for patients, and real-time results for both patients and clinicians through a linked clinical dashboard. The platform is designed for use in conditions such as asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease and pulmonary hypertension, which together represent one of the leading causes of death worldwide.

Using the device’s camera sensors, the system captures blood flow biomechanics and translates them into digital biomarkers. These provide metrics including heart rate, respiratory rate and tidal volume. The information is transmitted in real time to healthcare providers, who can use the data to guide treatment decisions.

“electronRx is dedicated to transforming the lives of people living with breathing disorders. pDx represents a major step forward in personalised respiratory care and we very much look forward to demonstrating the technology at HLTH,” said Dr Bipin Patel, CEO and Founder, electronRx.

“The platform’s scalable architecture supports integration into existing care pathways, allowing for proactive intervention and reduced reliance on in-person visits. By facilitating continuous monitoring, pDx helps clinicians personalise care while improving patient adherence and reducing healthcare burden. Most importantly, it gives patients greater flexibility and control over their healthcare journey.”

The company said the tool has been engineered to medical-grade standards and is intended to improve therapeutic outcomes by ensuring drugs can be adjusted more dynamically to patient need.
