1. Indication of Right Heart Cath.
2. Normal Values of Pressure and Oxymetry data in
right heart cath.
3. How to prepare a patient for right heart cath.
4. How & when to collect sample for oxymetry
during cath.
5. Calculation of cath data
Preparation for Right Heart Cath….
• Data Collection Sheet
• Special Instruments:
• Heparinized 3 c syringe
 NIH Catheter
Berman Catheter
Pig Tail Catheter
Make ready a Cardiac Cath Data
Collection sheet.
Make Ready heparinized 3cc syringes
• Keep an extra 3cc Syringe.
NIH Catheter (5.2 Fr,100cm)
Berman Balloon Catheter (6Fr,90cm)

RA -- 80% MPA

RV – 95% PCWP

Calculations…..
• Qp/Qs =
• (Aorta Oxygen sat- Mixed Venous Oxygen Sat)
/
( PV Oxygen sat – MPA Oxygen Sat)
= (.98- .80) / (.98- .95)
= 6
• PVR =
• (Mean PAP – PCWP) / CO
• = (24- 6) / CO
• CO
• = (Wt X 3) / (Aorta Oxygen Sat – Mixed
Venous Sat) X 1.36 X Hb X 10
CO
= (Wt X 3) / (Aorta Oxygen Sat – Mixed Venous Sat) X 1.36 X Hb X 10
• = (40 x 3) / (.98-.80) x 1.36 x 10 x 10
• = 4. 8
• CO = O2 consumption / AV O2 conc difference
• O2 Consumption = Wt X 3 ml
• AV O2 conc diff = (Aorta O2 content-Mixed
venous O2 content) x 10
• Aorta O2 content= Aorta O2 Sat x 1.36 x Hb
• Mixed Venous O2 content= MV O2 sat x1.36x Hb
• PVR =
• (Mean PAP – PCWP) / CO
• = (24- 6) / CO
• = 18 / 4.8
• = 3.75
