Lung function and the response to exercise were monitored in seven diver/welders who took part in a test saturation dive to 300 m for an average duration of 12 days; decompression took an average of nine days. Immediately after the dive the forced vital capacity was increased above base line by on average 0.51, the forced expiratory volume by 0.281 and peak expiratory flow rate by 0.71 s-1. There was no change in flow rate at small lung volumes (FEF 75% FVC). Recovery was complete and appeared to have a half time of 28 days. Transfer factor of the lungs for carbon monoxide (TlCO) was reduced by on average 9.6% after the dive but while partial recovery occurred, the values at one year were on average lower than those observed initially. The reason is unclear. One subject developed transient oxygen toxicity with stiff lungs and increased ventilation and cardiac frequency during submaximal exercise; a second subject developed similar changes but without accompanying symptoms. There is need for detailed physiological surveillance of people undertaking deep dives; this should be undertaken in circumstances that permit accurate measurements and full subject cooperation.
对7名潜水员/焊工进行了肺功能和运动反应监测，他们参与了一次至300米的试验性饱和潜水，平均持续12天；减压平均耗时9天。潜水结束后，用力肺活量平均比基线增加0.51，第一秒用力呼气量增加0.28升，呼气峰值流速增加0.71升/秒。小肺容积流速（FEF 75% FVC）无变化。恢复完全，半衰期似乎为28天。潜水后肺一氧化碳转运因子（TlCO）平均降低9.6%，虽然有部分恢复，但一年时的值平均低于最初观察值。原因尚不清楚。一名受试者在次最大运动期间出现短暂性氧中毒，伴有肺僵硬、通气增加和心率加快；另一名受试者出现类似变化，但无伴随症状。需要对进行深潜的人员进行详细的生理监测；这应在能够进行准确测量且受试者充分配合的情况下进行。
