Av Fistulas And Grafts Part 2

is one of the leading causes of mortality and morbidity in dialysis patients and is leading cause of _________.

It is important that a properly functioning vascular access be maintained for a _______ term hemodialysis.

Graft failure can occur without any signs of clinical ________.

Causes of graft failure: * *_ of graft, fistula or surrounding area is very common ** at the arterial or venous anastomosis in graft stenosis is more common *_ of graft or fistula (clue: clot)

Ultrasound can be used for which of the following: (more than 1)

The closer to the graft is to the heart, the better it is.

With chronic dialysis, what are the 2 most common grafts?

Check all that apply to the typical areas of placement in loop grafts:

A lesser used site for grafts is the _ to the . It is also rarely in the ______ vessels (used as last resort)

Grafts within the subclavian vessels tend to get easily __ and _ in this area can become potentially fatal leading to PE or stroke.

Check all that apply to straight grafts:

Fistulas last longer than grafts.

Fistulas are and are known for term patency and complication rates.

In regards to fistulas, this is a side to side type of connection?

The most common autologous fistula for dialysis is _artery to vein.

Check all that apply to the basic protocol for grafts:

Check all that apply to the basic protocol for fistulas:

When fistulas are created it must ______. Veins need to toughen and expand to withstand the _ pressure of dialysis. Flow becomes __________.

Maturation of fistulas can take up to _ to _ weeks after creation.

Name another access that is used temporarily until the fistula is ready to be used:

With fistulas, the vein can feel lumpy and dilate due to increased pressures in the vein

This is palpable flow within the access (you feel vibration)

If there is no thrill felt, the graft is usually ________

Never take a _ __ on the arm of access, which could lead to failure

What is the range of frequencies (transducer) used for grafts or fistulas?

Evalutaion of an inflow artery should be of ______ resistance

Flow distal to anastomosis, should be of ______ resistance

You assess a graft or fistula for which of the following:

When measuring flow volume, the inside diameter or area of graft is measured in (without color) and in you sample the region from which the diameter was measured.

This is the measurement of instantaneous average or mean velocity over time

What are the units of flow volume (Q)?

What is the flow volume equation?

Flow volume is done only on:

Flow volumes cannot be done in _____ because size of vein is too small and easily change size with transducer pressure.

When speaking of graft flow volumes: poor dialysis is less than _, the normal range is -, and possible CHF is greater than _.
