Effects of a NO-donor on bubble formation and survival

	NO donor, 5 days (Group VI)		NO donor, acute (Group VII)

	Ismo	Water	Ismo	Water
Body weight (g)	310 ± 7	309 ± 10	308 ± 6	307 ± 6
Scan grade	0 (0–5)^§	5 (3–5)	0 (0–5)^§	5.0 (3–5)
Survival (min)	60 (15–60)^§	27 (2–39)	60 (23–60)^§	19 (8–60)

^§

P < 0.001, significantly different from its respective control group. Body weights are presented as mean ±s.d.; the rest of the data are given as median (range). Decompression time was 12 min for all groups. Ismo, isosorbid mononitrate.
