Procedures Flashcards
What are the 7 common vascular access procedures
Venepuncture
Arterial puncture
Cannulation
Central venous catheter
Seldinger technique
Cardiac catheterisation
Swan-ganz catheter
What are the functions of vascular access procedures
Inject drug or fluid
Withdraw samples of blood
What is the venepuncture procedure
Needle inserted into vein
Collect blood, administer fluids, medication
What is an arterial puncture procedure
Needle inserted into artery
Collect blood, measure O2and CO2 levels or pH
Commonly done in radial or femoral arteries
Helps assess lung function and body’s acid-base balance.
Where in what arteries are arterial punctures normally done
Radial or femoral artery
Why is an arterial puncture normally done
To asses lung function and acid-base balance
What is the cannulation procedure
Inserting thin tube- cannula into vein or artery- typically vein
Often in hand or arm
Used to administer IV fluids, medications or drawing blood
What is the central venous catheter procedure
Long thin tube inserted into large vein- usually internal jugular, subclavian or femoral veins
Provides access to bloodstream
Administers medications, fluids, nutrition and drawing blood
For patients that have small veins that are hard to access or who need long term treatment.
Commonly used during surgery or for patients receiving chemotherapy
When are central venous catheters typically used
When a patient has small veins
Is undergoing chemotherapy
Requires long term treatment
Where is a central venous catheter typically inserted into
Internal jugular, subclavian or femoral veins
When are central venous catheters commonly used
During surgery or chemotherapy
What is the seldinger technique
Method commonly used for inserting catheters
What is the cardiac catheterisation procedure
Thin flexible tube- catheter- inserted typically into femoral, radial or brachial arteries, and guided into heart
What are cardiac catherisations used for
Check for blockages or other issues in the hearts blood vessels or chambers
Deliver treatments like angioplasty- widen arteries
Or stent placements
What is the swan-ganz catheter also known as
Pulmonary artery catheter
What is the swan-ganz catheter procedure
Used to measure pressures in the heart and lungs
Commonly used in critically ill patients to monitor heart function, fluid balance and response to treatment
Where are swan-ganz catheters inserted
Jugular or subclavian vein
Pulmonary artery
