Study for the Evaluation of a Non-invasive Hemodynamic Measurement in Heart Failure Patients

Conditions

ezCVP measurement — DEVICE
* Measuring device: non-FDA-cleared patient monitor (740E, Zoe Medical, MA, US), which has software to measure ezCVP. * Sensor: an FDA-cleared pulse oximeter sensor for adults (K012891: DS-100A, Nellcor, CA, US). * Cuff: an FDA-cleared NIBP cuff for adults (K080342: YP-713T, YP-714T or TP-715T, Nihon Kohden Corporation, Tokyo, Japan).

Track changes in non-invasive central venous pressure across hospital stay and relationship with readmission

Arm: Adult CHF subjects with initial high CVP
Adult subjects with congestive heart failure diagnosis who have an indicated high non-invasive estimated central venous pressure on first measurement after clinical unit admission.
Arm: Adult CHF subjects with initial low CVP
Adult subjects with congestive heart failure diagnosis who have an indicated low non-invasive estimated central venous pressure on first measurement after clinical unit admission.

Evaluate the difference between non-invasive CVP measurement at admission and at discharge [ Time Frame: 7 days ]
