Brief Summary:
The aim of the study is to determine the feasibility of collecting respiratory parameters during recompensation following ADHF (Acute Decompensated Heart Failure)with non-invasive measurements. This could lead to a better understanding of how respiratory parameters may change during re-compensation therapy and could also be a comfortable method for patients.

Condition or disease Intervention/treatment Phase
Acute Decompensated Heart Failure (ADHF) Acute Cardiogenic Pulmonary Edema (ACPE) Device: non-invasive respiratory parameter measurements Not Applicable

Detailed Description:

The study is designed as a single-center, open, interventional, observational study according to clause §23b of the German Medical Device Act (MPG). The study will recruit 50 patients suffering from cardiogenic pulmonary congestion and edema including ambulant patients and patients of intensive care.

We will investigate whether respiratory parameters during re-compensation are related to the therapy effects and changes in pulmonary congestion status. This study will collect data in an observational and clinical setting in the re-compensation phase of ADHF.

Correlation between measured lung and respiratory parameters and standard clinical parameters characterizing stages of re-compensation will be undertaken. Standard clinical parameters may include diuretics and other cardiac medication dose frequency, weight, heart rate, respiratory rate, chest x-rays (when routinely performed), symptoms such as shortness of breath or fatigue, biomarkers such as brain natriuretic peptide (BNP), stroke volume, cardiac output, and oxygen requirements.

Primary Outcome Measures :
  1. Correlation between current standard clinical assessment of re-compensation and measured respiratory parameters [ Time Frame: about 3 months ]
    stationary as well as ambulant patients with acute decompensation receive clinical standard measurements and will be measured with the help of non- invasive technology such as respiratory profile and gaz analysis, bioimpedance spectroscopy. Patients will be measured at baseline and 2 times at ward if applicable and at 3 months follow up visit. Measurements will take 1:30 hours per visit.
