Vascular catheters and devices: Access to circulation for administration of drugs, resuscitative fluid, and nutrition; emergent venous access; obtaining blood samples; hemodialysis; and hemodynamic monitoring/support
Central venous catheter (CVC): Short-term drug/fluid administration; venous access
Peripherally inserted central catheter (PICC): Mid- and long-term central venous access
Tunneled central catheter
Long-term central venous access: Weeks-months
Port catheter (PC): Drug (chemotherapy), nutrition, fluid administration
Hemodialysis catheter (HDC): Hemodialysis, nutrition, transfusion, drug administration
Pulmonary artery catheter (PAC): Measurement of central venous, intracardiac, pulmonary arterial, and pulmonary capillary wedge pressures
Pulmonary capillary wedge pressure reflects left atrial and left ventricular end-diastolic volume
Intra-aortic balloon pump (IAPB)
Temporary mechanical hemodynamic support in patients with cardiogenic shock using counterpulsation
Aortic balloon inflates in diastole (↑ coronary and peripheral organ perfusion); deflates in systole (↓ afterload)
Impella heart pump: Transcatheter intracardiac ventricular assist device for short-term mechanical circulatory support (cardiogenic shock; left heart failure)
Impella RP: Right or biventricular heart failure
Extracorporeal membrane oxygenation (ECMO): Modified pulmonary/cardiopulmonary bypass for cardiorespiratory support in severe cardiac/respiratory failure
Veno-venous (VV): Primarily for gas exchange
Veno-arterial (VA): Gas exchange and hemodynamic support
CardioMEMS: Ambulatory heart failure monitoring
Pulmonary artery pressure and heart rate measurements
Daily wireless transmission of pressure readings
