Table 2. R-tymp compliance (ml), R-tymp peak pressure (dPa) and peak pressure difference after Valsalva manoeuvre (R-VdP) (dPa) in different experience groups of divers; 'professional' divers had higher compliance values (P = 0.004) and lower peak pressures (P = 0.01) compared to divers with lower experience; R-VdP was greatest in inexperienced divers (P = 0.02); 95% CI – 95% confidence interval .
| R-tymp compliance (ml) | R-tymp peak pressure (dPa) | R-VdP (dPa) | ||||
| Diving experience | Mean | (95%CI) | Mean | (95%CI) | Mean | (95%CI) |
| Inexperienced (n = 13) | 0.9 | (0.5 to 1.4) | 9.5 | (-17 to 36) | 39.3 | (-3.7 to 82.2) |
| Intermediate (n = 5) | 0.7 | (0.1 to 1.3) | -13.8 | (-42.3 to 14.7) | 13.4 | (-33 to 59.8) |
| Professional (n = 5) | 1 | (0.3 to 2.6) | -23.1 | (-53 to 6.7) | -6.9 | (-55.7 to 41.9) |
