RESPIRATORY CHANGES IN STRANDED BOTTLENOSE DOLPHINS ().

Lung function (breath duration, respiratory flow [], and tidal volume []), and end-expiratory O were measured in 19 adult bottlenose dolphins ( spp.) while at rest in water or beached for up to 10 min. The results show that inspiratory , expiratory , or inspiratory did not differ on land or in water.

Ventilation and gas exchange before and after voluntary static surface breath-holds in clinically healthy bottlenose dolphins, .

We measured respiratory flow (), breathing frequency (), tidal volume (), breath duration and end-expired O content in bottlenose dolphins () before and after static surface breath-holds ranging from 34 to 292 s. There was considerable variation in the end-expired O, and following a breath-hold. The analysis suggests that the dolphins attempt to minimize recovery following a dive by altering and to rapidly replenish the O stores.
