AVA CERTIFICATION EXAM QUESTIONS
AND ANSWERS- MEASURING CENTRAL
VENOUS PRESSURE
Circulating blood flows into the right atrium - Answer-via the inferior and superior vena cava
Central Venous Pressure - Answer-the pressure in the right atrium
What determines how often the CVP measurement should take place? - Answer-The condition of the
patient and the treatment determines how often CVP is measured.
Critical unstable patients may need hourly CVP measurements.
Equipment required to measure CVP? - Answer-Indwelling central venous catheter
pressure manometer or transducer.
Manometers are commonly used on wards.
Accident and Emergency departments, High Dependency areas and Intensive Care units use transducers
for measuring - Answer-Central venous pressures
CVC insertion sites? - Answer-internal jugular vein
subclavian vein
, femoral vein
Measuring central venous pressure: 3 Insertion sites -
1 - Internal jugular veins - Answer-Number one:
frequently chosen
high success rate
low incidence of complications like pneumothorax
IJ veins are short straight and relatively large
catheter occlusion may occur related to head movement and may cause irritation in conscious patients.
Measuring central venous pressure: There are 3 CVC Insertion sites -
Number 2: Subclavian Veins - Answer-recommended as more comfortable for the patient
more recognizable anatomical landmarks
risk of pneumothorax due to it's position beneath the clavicle
Measuring central venous pressure: There are 3 CVC Insertion sites Number 3: Femoral Veins - Answer-
offers rapid emergent access such as cardiac arrest
placement near groin increases infection rates
uncomfortable when moving for conscious patient.
CVP is recorded where on the patient? - Answer-mid-axillary line which is found, with the
manometer arm or transducer level with the phlebostatic axis
The phlebostatic axis where the CVP is recorded is found where? - Answer-Where the fourth intercostal
space and
mid-axillary line cross each other
