This narrative review by Hyfe's R&D team makes the case that continuous cough monitoring (CCM), powered by acoustic AI, transforms cough from a subjective symptom into a quantifiable digital biomarker.
This ERS 2025 abstract from Hyfe's R&D team validates the wear-detection algorithm built into the Hyfe CoughMonitor smartwatch against participant-reported wear status across 418 person-hours of data in ten participants.
Authored by Hyfe's R&D team, this review synthesizes work presented at the European Respiratory Society Congress 2025 and argues that objective cough monitoring has crossed a practical threshold, moving from experimental technique to deployable clinical endpoint.
This study asked whether the core components of BCST could be embedded in a digital therapeutic and paired with continuous, objective cough monitoring inside the CoughPro app.

Real-time continuous cough monitoring using wearable technology is a novel technique of quantifying disease severity in patients with chronic cough. Little is known about how daily objective cough count measured by such devices correlates with subjective assessment of symptoms in cough patients.
Patients with chronic cough were monitored the Hyfe CoughMonitor for 30 consecutive days and concomitantly recorded daily cough severity scores using the Cough Visual Analogue Scale (VAS). Objective cough count data collected was recorded and correlated with daily VAS scores.
12 Patients recorded a median of 93 coughs per day (range 3-637) with a mean (SD) cough VAS score of 43mm (24mm). There was no significant association between daily cough count and daily cough VAS score in any of the patients. Scatter plots demonstrating these relationships can be visualised in Figure 1 and the Pearson correlation coefficients can be seen in Table 1.
There is no association between daily objective cough counts and daily cough VAS scores, more work is required to find the optimal endpoint for responses to treatment for chronic cough.
