Central Venous Pressure in the Veterinary Patient (for Nurses)

A central venous catheter should not be placed in a patient who has a:

Leukopaenia

Thrombocytopaenia

Anaemia

Hypernatraemia

Conditions that may impact a Central Venous Pressure measurement include:

Right heart disease

Left heart disease

Broken heart disease

Temperature

Which law dictates how cardiac filling pressures relate to cardiac output?

Boyle’s Law

Starling’s Law of capillary

The Pressure Law

Frank-Starling mechanism

An increased central venous pressure suggests:

Hypovolaemia or increased venous compliance

Hypertension

Hypervolaemia or reduced venous compliance

Hypotension

A patient with a CVP of 5 cmH2O would be:

Hypovolaemic

Hypervolaemic

Normovolaemic

Potentially any of the above depending on other factors such as cardiac function and vessel wall compliance

When measuring CVP it is important to place the zero level at:

The point of the shoulder in lateral recumbency

The manubrium in lateral recumbency

The sternum in sternal recumbency

The right side of the chest in any position

When administering a fluid challenge, normovolaemia is suggested by a CVP rise of:

2 cmH2O with a return to baseline over 5 minutes

10 cmH2O with a return to baseline over 15 minutes

2 cmH2O with a return to baseline over 30 minutes

2-4 cmH2O with a return to baseline over 10-15 minutes

Choose the incorrect answer: Benefits of central venous lines include:

Delivery of large volumes of fluids

Monitoring of cardiac output in patients with left sided heart failure

Administration of chemotherapy drugs

Frequent blood draws in critical patients

The equipment used to measure CVP can include a:

Manometer

Thermometer

Hygrometer

Micrometer

Complications of central venous catheters do not include:

Haemorrhage

Air emboli

Haemabdomen

Arrhythmia
