PA lines Flashcards
purpose of PA line
direct assess of R heart function
indirect of L heart fnctn
indications
- assess CVs and response to therapy, pulm status and response, fluid requirements
- monitor of a PT with multi system failure
what is connected to the proximal port
Transduced CVP
RAP
R side preload
blue
- there is also a syringe for CO attached to blue CVP lumen
what is attached to the distal port
color?
the transducer for the PA- will read the pressures
yellow
what is a cortis
how do you measure
line that is introduced into vein
find the thick black line closest to the top of cordis, that is 50cm. every other small line is 10 cm
- *measure from top of cordis to first black line, subtract measurement from black lines and measurement to hub
ex. 50 - 8 = 42 cm - have TKVO running all the time
what is the significance of PAD and PCWP being 1-4 apart
then you can use the number taken from the PAD without having to inflate the balloon for that shift
only use the PAD for L sided Preload if….
- the PAD is normal
- if the wedge and PAD are within 1-4 of each other
- if there is no lung pathology
complications of PA insertion
- dysrhythmias
- pneumothorax
- balloon rupture
- ischemia/infarction
- artery rupture
- infection
- knotting
when to obtain a hemodynamic profile?
- baseline
- aid in diagnosis
- following any sudden change
- assess specific intervention
med titration, vnet changes, add/dc meds, volume/diuretics - ongoing trending
wedging the PA *****
- level/zero/ PT position
- assess waveform,
- 1.5cc air in balloon, inject SLOWLY
- watch wave
- inflate balloon with the minimal air needed to obtain PCWP wave
- hold 3 resp cycles or max 15 sec
- read PCWP at end-expiration
- allow balloon to deflate passively
cardiac outputs
- inject D5W or NS
- usually 10cc through proximal port
- fast and steady no longer 4 sec
- min of 3 CO’s within 10% of each other
- average values
if CO and CI are on the low side
then a good indicator of contractility
not if these numbers are on the high side
when is the ERO2 increased
then there is increased demand
if ERO2 is high what is SvO2
when are the possibly normal?
decreased. ERO2 high from demand and SvO2 lower from more being consumed
both could be normal (60-80 and 25-35) in sepsis
who removes the PA line?
MD
