This is a multi-site, international, prospective, non-blinded, non-randomized, observational study. This study aims to compare measurements from the VQm PHM™ to existing clinical measurements, assess safety of the device and determine effects that standard clinical events have on the VQm PHM™ measurements. This study does not include changes to clinical care based on measurements from the VQm PHM™. Each patient will serve as their own control.
