Purpose of arterial line
|
Continuous monitoring of BP
frequent measuring of ABGs |
Equipment needed (5)
|
Catheter
pressure bag (300 mm Hg) fluid for flush monitor pressure tubing with transducer |
4 A line complications
|
Thrombosis
embolism hemorrhage infection |
What to do for dampened waveform?
|
Aspirate blood to remove any possible clot
square wave test if still dampened check HR and NBP |
A line implications
|
Neutral wrist position
aseptic technique high and low alarms pinpoint pressure when catheter is removed |
CVP monitors what?
Can increase with and decrease with? normal level? |
-fxn of right side of heart (tells if blood flow to lungs is compromised) and preload of rt ventricle
- fluid administration and diuresis - 2-8 mm Hg |
PA aka swan ganz line :
PAWP measures: normal: |
Indirect measure of left ventricular end-diastolic pressure
6-12 mm Hg |
PADP
|
Read continuously
4-12 mm Hg |
PA line can tell if pt has:
|
Pulmonary HTN
|
PA can also measure
|
Afterload
CO (4-8 L) SV (60-100) |
Complications of PA lines
|
Systemic infection
air embolus pulmonary rupture/infarction ventricular arrhythmias |
Circulatory assist devices
|
Intraaortic balloon pump
ventricular assist device artificial heart |
ET placement
|
ETCO2
vent readings ABGs bilateral breath sounds |
Mechanical ventilation complications
|
Barotrauma
volu-pressure trauma alveolar hypotension alveolar hypertension VAP |
