Compression Arthralgia (also called compression pains<\/em>)\u00a0can onset as shallow as 60m\/200ft but becomes more significant as depth\/pressure increases. <\/p>\n\n\n\n The severity of compression pains is determined by:<\/p>\n\n\n\n There is also a varying level of individual susceptibility.<\/p>\n\n\n\n Compression arthralgia is typically associated with saturation divers at extreme depth<\/a>. However, it must be remembered that these divers typically conduct very slow compression (descent rates circa 1m per minute). \u00a0<\/p>\n\n\n\n Recreational technical divers would typically encounter much higher rates of compression during air or trimix<\/a> dives (descent rates circa 20-30m per minute). As a result, they provoke compression arthralgia at much shallower depths.<\/p>\n\n\n\n\n
