Study Notes
Central Venous Pressure (CVP) Overview
- CVP indicates the amount of blood returning to the heart and the heart's ability to pump that blood into the arterial system.
- Reflects right atrial pressure, providing insights into fluid status, cardiac function, and intrathoracic pressure.
Indications for CVP Monitoring
- Indicated for patients with volume overload, heart failure, or septic shock to assess fluid status.
- Useful in monitoring patients requiring fluid resuscitation or those on medications affecting cardiac output.
Absolute Contraindication for CVP Monitoring
- Absolute contraindication includes the presence of a known thrombosis in the central venous access site.
Relative Contraindications for CVP Monitoring
- Relative contraindications may include coagulopathy, infection at the insertion site, or severe anatomical abnormalities.
Challenges in Venous Access
- Inability to obtain venous access in emergent situations may arise from factors like extreme obesity, poor venous visibility, or anatomical variations.
