Pulmonary artery catheter Flashcards
what is the PA cath used for
to assess LV function
the shaft markings on the PA cath are in what increments?
10cm
How for to the right atrium? right ventricle? pulmonary artery?
Subclavian
15 cm
25cm
40 cm
How for to the right atrium? right ventricle? pulmonary artery?
Right IJ
20 cm
30 cm
45 cm
How for to the right atrium? right ventricle? pulmonary artery?
Left IJ
25 cm
35 cm
50 cm
how to remembe the distancs to the right atrium? right ventricle? pulmonary artery?
know right atrium length
add 10cm for right ventricle
ad 15 cm for Pulmonary artery
What is the pressure in the right atrium and describe the wave form
1-8mmhg
low aplitude
has a wave and v wave
the right atrial pressures equals what?
cvp
What is the pressure in the right ventricle and describe the wave form
systolic 15-25 mmHg diastolic 1-8 mmHg
larger than atria (d/t increased pressure)
Downstroke WITHOUT dicrotic notch
What is the pressure in the pulmonary artery (include mean) and describe the wave form
systolic 15-25mmHg Diastolic 8-15mmHg
Mean 10-20mmHg
smaller than ventricular wave form
Diastolic step up
dicrotic notch present (pulmonic valve closure)
what is normal PCWP
6-12 mmHg
what does PCWP measure?
back pressure form the pulmonary veins
the PCWP is NEVER higher than what pressure?
PA diastolic pressure
what 3 heart measurments all have the values of 0-8mmHg and thus equal each other?
RAP=CVP=RVEDP
what 2 heart pressures have the value of 15-25 mmHg and thus equal each other
RVS=PAS = 15-25 mmHg
you inserted this swan-ganz in to the RIJ, for each location state:
where the tip of the catheter is located
how far the catheter has been inserted
and normal pressures
- A) right atrium, 20 cm, 1-8mmHg
- B) right ventricle 30cm, 15-25 / 1-8mmHg
- C) PA, 45cm, 15-25/ 8-15mmHg Mean 10-20mmHg
- D) PCWP 45-50cm, 6-12mmHg
