Which gas exchange inefficiency occurs when swim bladder volume change lags during rapid ascent?

💡 Explanation

When swim bladder volume lags during rapid ascent, the partial pressure of oxygen in the blood decreases relative to nitrogen due to inefficient Countercurrent Exchange at the gills reducing oxygen uptake, causing diffusion within the capillaries to slow. Therefore Hypoxia results via oxygen diffusion limitation, rather than hypercapnia, narcosis or toxicity which involve altered respiratory regulation .
