Physiology of Surgery Flashcards
Provides information to the cardiopulmonary status of the patient
hemodynamic monitoring
Indications for arterial catheterization
continuous blood pressure monitoring or frequent arterial blood sampling
T/F there are no absolute contraindications to arterial catheterization
true
used to determine whether the patency of the radial or ulnar artery is normal. It is performed prior to radial cannulation or catheterisation
allen test
Most commonly used site for arterial catheterization because of dual blood supply, easy access, low complication rate
radial artery
Risk for catheters that have been in place for more than 4 days
infection
Potential complication of arterial catheterization resulting when the vessel has been punctured that causes a leak of blood into surrounding tissue that’s walled off
pseudoaneurysm
Indications for central venous catheterization
access for fluids/drugs, parenteral nutrition, and CVP monitoring
provides info about the relationship between intravascular volume and right ventricular function
CVP
Critical problem in seriously ill patients
determination of the proper amount of fluids and bloods necessary to maintain blood volume
Most common complication of central venous catheterization through subclavian vein
pneumothorax
Most common complication of central venous catheterization through internal jugular vein
puncture of carotid artery
Reflects ability of the cardiac pump to handle returning blood volume
CVP or right atrial pressure
What does a CVP between 0-3 indicate?
circulating blood volume is below the normal blood volume the heart can handle
What does a CVP between 8-20 indicate?
circulating blood volume is higher than the normal blood volume the heart can handle
