Table 3.
Comparison of lymph transit times from hand to axilla (ttransit) in the same three healthy subjects in the absence and presence of pressure occlusion
| Subject | ttransit without cuff (min) | ttransit with cuff (min) | Increase in ttransit with cuff (-fold) | Ppump (mmHg) |
|---|---|---|---|---|
| A | 3 | 42 | 14.0 | 50 |
| B | 6 | 63 | 10.5 | 30 |
| C | 6 | 33 | 5.5 | 50 |
| Mean | 5 | 46 | 10.0 | 43 |
The pressure cuff around the upper arm was initially at 60 mmHg for 30 min, then reduced in steps (see Cuffed protocol, Methods). Corresponding estimate of lymphatic pumping pressure, Ppump, also shown.
