What’s Inside?

This case study describes the use of the RESP® Biosensor for daily home monitoring following hospital discharge for a severe asthma exacerbation. A man in his sixties, hospitalized for three weeks and intubated twice, was monitored at home with structured nine-minute recordings each morning and evening, which included normal breathing, deep breathing, and coughing. Recordings were analyzed by board-certified physicians for adventitious sounds such as wheezes and rhonchi, while the patient self-reported symptom severity.

Lung sound abnormalities decreased steadily in the first four days after discharge but then rose consistently over the following three days, leading to readmission on day seven. The patient’s subjective symptom scores also worsened in the two days preceding readmission, but increases in abnormal sounds were evident earlier.

This case highlights the feasibility and value of remote lung sound monitoring at home, showing how the RESP Biosensor can detect pre-symptomatic changes that may allow earlier intervention and potentially prevent costly hospital readmissions.
