Overview
Brief Summary
Pulmonary Artery Compliance measurements will be obtained with the Respirix device in patients with congestive heart failure decompensation. Echocardiogram, weight measurements, and BNP will also be gathered as independent measures of decompensation in the clinic. Pulmonary Artery Compliance measurements will be made daily during the hospital stay. Patients can continue using the device at home for the next 3 weeks. Each patient will serve as their own control and relative changes from their baseline will be recorded for each parameter.

Outcomes
Primary Outcomes
Diuretics resulting in fluid status changes in severely compensated CHF patients from hospital admit time to discharge and to follow up visit
Time Frame: Through study completion, up to 1 month depending on readmission
Comparing fluid management (diuretics) to daily CardioSpire's non-invasive Pulmonary Artery Compliance (nPAC) value over the time course from decompensation (at hospital admission) through compensation (discharge) and at their follow up visit, in congestive heart failure patients (CHF).
Fluid status based on weight changes in severely compensated CHF patients from hospital admit time to discharge and to follow up visit
Time Frame: Through study completion, up to 1 month depending on readmission
Comparing fluid management (through weight changes) to daily CardioSpire's non-invasive Pulmonary Artery Compliance (nPAC) value over the time course from decompensation (at hospital admission) through compensation (discharge) and at their follow up visit, in congestive heart failure patients (CHF).
Vasoactives resulting in fluid status changes in severely compensated CHF patients from hospital admit time to discharge and to follow up visit
Time Frame: Through study completion, up to 1 month depending on readmission
Comparing fluid management (vasoactives) to daily CardioSpire's non-invasive Pulmonary Artery Compliance (nPAC) value over the time course from decompensation (at hospital admission) through compensation (discharge) and at their follow up visit, in congestive heart failure patients (CHF).
Clinical congestion measurement changes in severely compensated CHF patients from hospital admit time to discharge and to follow up visit
Time Frame: Through study completion, up to 1 month depending on readmission
Comparing clinical congestion measurement (taken as standard of care) to daily CardioSpire's non-invasive Pulmonary Artery Compliance (nPAC) value over the time course from decompensation (at hospital admission) through compensation (discharge) and at their follow up visit, in congestive heart failure patients (CHF).
