A study for evaluating the feasibility of SenseGuard in assessing the respiratory condition change of hospitalized patients with exacerbation of COPD, by monitoring respiratory parameters. The study duration for each patient will start at the time of enrollment until the patient is released, or until the optional post-discharge follow-up visit.
The study will include at least one visit per day: The visit and measurement with SenseGuard will start prior to the first medical exacerbation treatment effect-onset given on each study day (by inhalation or IV). The measurement with SenseGuard will be done before and after treatment.
At the investigator discretion, additional two similar visits could be performed on the same study day, with or without the admission of the medical exacerbation treatment.
During the study, both the investigator and the patients will be asked to fill questionnaires to assess the patient's condition Additionally, measurements that are performed and collected as a standard practice or at the request of the medical personnel as part of patient's treatment course shall be documented and used as a reference for the study device assessment.
