Abstract
We have conducted a trial of a wireless device for continuous cardiopulmonary monitoring. Its performance, user acceptance and safety were assessed for monitoring in the patient's home. The study included 20 patients: six with chronic obstructive pulmonary disease, six with chronic heart failure, seven with atrial fibrillation and palpitations, and one with a snoring problem. The system recorded the heart rate and respiratory rate, blood pressure, electrocardiogram and body temperature. The results were transmitted automatically to a central monitoring station. The accuracy of the measurements was checked by a comparison system and also by conventional measurements performed by a nurse. The system was acceptable to patients and functioned satisfactorily in the home. An important facet of home telemonitoring may turn out to be its greater reliability in collecting objective data.
