lactating, or patients with known psychiatric or neurological disease who are unable
to consent. Patients who do not have a functional peripheral IV as part of standard
care.
Vasoactive and Inotropic Agents
Inclusion Criteria:
- Hospitalized patients with central venous access and pulmonary arterial catheter in
place, requiring infusion of vasoactive and/or inotropic agents; Age >=18
Exclusion Criteria:
- Cardiac assist devices (intra-aortic balloon pump, ventricular assist devices, and
extracorporeal membrane oxygenation), ongoing ACLS, severe tricuspid regurgitation or
stenosis, patient with restrictive cardiomyopathies (cardiac amyloidosis), patients
receiving pulmonary vasodilators (nitric oxide, sodium nitroprusside, sildenafil),
atrial fibrillation, congenital heart disease, female patients who are pregnant or
lactating, or patients with known psychiatric or neurological disease who are unable
to consent. Patients who do not have a functional peripheral IV as part of standard
care.
Congestive Heart Failure
Inclusion Criteria:
- Patients presenting to Vanderbilt University Medical Center with the diagnosis of
congestive heart failure and present with symptoms of fluid overload; Age>=18
Exclusion Criteria:
- Cardiac assist devices (intra-aortic balloon pump, ventricular assist devices, and
extra corporeal membrane oxygenation), ongoing ACLS, active irregular heart rhythm,
patient with restrictive cardiomyopathies (cardiac amyloidosis), or constrictive

extra corporeal membrane oxygenation), ongoing ACLS, patients with restrictive
cardiomyopathies (cardiac amyloidosis) or constrictive cardiac disease (constrictive
pericarditis or cardiac tamponade), congenital heart disease other than foramen ovale,
repaired atrial or ventricular septal defect, female patients who are pregnant or
lactating, or patients with known psychiatric or neurological disease who are unable
to consent. Patients who do not have a functional peripheral IV as part of standard
care.
Patients undergoing Surgery
Inclusion Criteria:

line placement; Age >=18
Exclusion Criteria:

extra corporeal membrane oxygenation), ongoing ACLS, patients with restrictive
cardiomyopathies (cardiac amyloidosis) or constrictive cardiac disease (constrictive
pericarditis or cardiac tamponade), active irregular cardiac rhythm, congenital heart
disease other than foramen ovale , repaired atrial or ventricular septal defect,
female patients who are pregnant or lactating, patients with known psychiatric or
neurological disease who are unable to consent, or any other medical condition which,
in the opinion of the investigator, would place the patient at undue risk from
participation in the trial. Patients who do not have a functional peripheral IV as
part of standard care.
