Grading of skin lesions according to lesion area (x ± SD).
| Lesion area (%) | n | Latent time to stage III lesion (min) | Average bubble grade |
|---|---|---|---|
| <30% | 4 | 56.3 ± 12.5 | 2.3 ± 0.9 |
| 30%~50% | 4 | 31.3 ± 13.2 | 2.9 ± 0.5 |
| >50% | 3 | 15.0 ± 5.0 | 3.6 ± 0.5 |
Skin lesions were observed in 11 swine decompressed from a simulated air dive to 40 m-35 min. Circulating bubbles were detected and scored. According to the area and/or latency to Stage III lesion, the bubble grade could be estimated.
