Vascular Access and Monitoring Flashcards
A central venous catheter is inserted until the top resides where?
Just outside the right atrium and superior vena cava.
Which port on a CVC is used to monitor a patients CVP?
Use the distal port because it is the closest to the heart.
List types of CVC’s.
Tunneled, non-tunneled, implanted device (or port), and peripherally inserted central catheter.
List indications for central venous catheter placement.
Long term access, difficult access, hemodynamic monitoring, dialysis, administration of caustic medications, introduction of a transvenous pacemaker, and parental nutrition.
What are the three sites for CVC insertion?
Subclavian, internal jugular, femoral.
Following insertion of ALL CVCs a CXR (chest x-ray) is required?
NO. Subclavian and external jugulars need an x-ray, but femoral does not (couldn’t see it on chest x-ray anyways).
The gauge of the distal port on a non-tunneled CVC is?
Usually is a 16gauge. The other ports will be 18g if it’s a triple lumen.
Monitoring the CVP requires the transducer to be levelled at the what?
The phlebostatic axis.
List complications of CVCs.
Hematoma, infections, wrong placement, pneumothorax, air embolus, or loss of a guide wire.
List 2 indications to perform blood sampling via radial artery puncture.
Accessing patients current status, acid/base balance, confirm treatment plan, and to evaluate your current interventions.
List contraindications for radial arterial sampling.
A failed Allen’s test, trauma or burn to the site, to many attempts at the site, previous surgery, graft, or fistulas.
What volume of blood is required for your ABG sample via arterial puncture?
1 mL
What angle do you hold the needle at for arterial puncture?
30 to 45 degrees
What are indications for an arterial line?
Frequent lab testing including ABG’s, monitoring SPO2 and CO2 levels in patients with respiratory problems, the need for accurate continuous blood pressure monitoring, and can also be used in conjunction with ICP monitoring.
What are some complications related to arterial monitoring?
Pain, hematoma, hemorrhage, artery laceration and injury, arterial vasospasm, pseudoaneurysm formation, arteriovenous fistula, infection, limb ischemia, thrombosis/embolism, and nerve damage/neuropathy.
