1

what is the PA cath used for

 

to assess LV function

 

2

the shaft markings on the PA cath are in what increments?

10cm

3

How for to the right atrium? right ventricle? pulmonary artery?

Subclavian

15 cm

25cm

40 cm

 

4

How for to the right atrium? right ventricle? pulmonary artery?

Right IJ

20 cm

30 cm

45 cm

 

 

5

How for to the right atrium? right ventricle? pulmonary artery?

Left IJ

25 cm

35 cm

50 cm

6

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

7

What is the pressure in the right atrium and describe the wave form

1-8mmhg

low aplitude

has a wave and v wave

8

the right atrial pressures equals what?

cvp

9

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

10

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)

11

what is normal PCWP 

6-12 mmHg

12

what does PCWP measure?

back pressure form the pulmonary veins

13

the PCWP is NEVER higher than what pressure?

PA diastolic pressure

14

what 3 heart measurments all have the values of 0-8mmHg and thus equal each other?

RAP=CVP=RVEDP

15

what 2 heart pressures have the value of 15-25 mmHg and thus equal each other

RVS=PAS = 15-25 mmHg

16

what is PAD pressure?

8-15 mmHg

17

what would happen to CVP and PCWP?

hypovolemia

 CVP low

PCWP low

18

what would happen to CVP and PCWP?

LV failure

 CVP normal/hig

PCWP high

19

what would happen to CVP and PCWP?

Cardiac tamponade

CVP high

PCWP high

20

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
