Individual values of systolic pulmonary artery pressure (PAP) measured by three techniques (Doppler echocardiography, cardiac catheterisation with fluid filled Swan Ganz catheter, and micromanometer tipped pulmonary artery catheter while lying awake)
| Patient no. | Echo systolic PAP (mm Hg) | Catheter laboratory systolic PAP (mm Hg) | Ambulatory catheter systolic PAP (mm Hg) |
|---|---|---|---|
| 1 | 40 | 34 | 37 |
| 2 | 70 | 65 | 59 |
| 3 | 68 | 90 | 101 |
| 4 | 88 | 90 | 117 |
| 5 | 100 | 85 | 98 |
| 6 | 70 | 90 | 99 |
| Mean (SD) | 72.7 (20.4) | 75.8 (22.6) | 85.2 (30.4) |
The lying awake value from the micromanometer tipped pulmonary artery catheter was chosen because that is the posture in which conventional cardiac catheterisation measurements are made.
