(34 cards)
whats being measured in the right heart
RVEDP, CVP, RAP
whats being measured in the pulmonary system
PCWP, PASP, PADP, PAMP
where is pvo2 and svo2 measured
pulmonary
where is pulmonary and tricuspid function measured
right heart monitoring
whats being measured in the left heart
LVEDP, LV function, PAWP
where is CMO and SVR measured
left heart
what happens when the transducer is above midchest
every inch above pressure will be 2mmhg less than actual
what happens when the transducer is below midchest
every inch below pressure will be 2mmhg greater than actual
how long is the catheter
110 cm
distal port - where is it and where does it go
at the tip and pulmonary artery
distal port uses
measures PAP and PWP, obtains mixed venous samples, injects medications
balloon port where is it and where does it go
3 cm goes into pulmonary
balloon port uses
used for insertion
allows catheter to wedge for PCWP reading
thermistor - where is it and where does it go
4-5 cm from tip
used to check temp of blood
what ports are needed for CMO measurement
thermistor and proximal lumen
proximal lumen - where is it and where does it go
30 cm and opening is in right atrium
proximal lumen uses
reads RA pressure
administers drugs and fluids
samples blood
injects saline for CMO reading
where are the ventricular pacemaker bands
20 cm
where are the atrial pacemaker bands
30 cm
oxygen saturation port does?
measures venous saturation
atrial/ventricular port does?
cardiac pacing
continuous cardiac output measures
CMO
where must the catheter be located in the lungs
zone II
right atrium waveform normal pressure
2-6mmhg
