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.

Inclusion criteria
✓. Males and females, ages 18-75
✓. Able and willing to provide written informed consent or not able to give informed consent because of mechanical respiration
✓. Diagnosis of acute or chronic decompensated heart failure with pulmonary congestion or edema
✓. Systolic blood pressure \>80 mm Hg at time of enrollment
✓. Resting pulse oximetry (SpO2) at the time of enrollment of at least 88% at 21% iron oxides (FeO2)
✓. Agreement to be measured with the study devices according to study protocol by patient or legal representative
✓. Left ventricular ejection fraction (LVEF) \< 40% in 3D- Echocardiography
Exclusion criteria
✕. Active participation in another interventional research study
✕. Surgery of the upper airway, nose, sinus or middle ear within the last 90 days
✕. Major medical or psychiatric condition that would interfere with the demands of the study or the ability to complete the study. For example, severe unstable chronic lung disease such as obstructive (FEV1/FVC ≤ 30%), or restrictive (FVC \< 50% predicted) lung disease, neuromuscular disease, cancer, or renal failure
✕. Unable to use PAP therapies due to physical issues (e.g. facial structural abnormalities) or cognitive issues (e.g. dementia)
