Abstract: In the elephant, there is concern that lateral recumbency (LR) impairs respiratory muscle and lung function resulting in clinically significant arterial hypoxemia. Using healthy adult female Asian elephants (Elephas maximus, n=6),
the hypothesis was tested that, given the O(2) binding characteristics of elephant blood, substantial reductions in arterial O(2) pressure (Pa(O(2))) in LR could be tolerated without lowering arterial O(2) content appreciably. Fifteen minutes of LR
decreased
Pa(O(2)) from 103+/-2 (upright, U) to 77+/-4 mmHg (P<0.05) and hemoglobin O(2) saturation (U, 97.8+/-0.1, LR, 95.3+/-0.5%, P<0.05). However, due to a recumbency-induced hemoconcentration, arterial O(2) content was unchanged (U, 18.2+/-2.4, LR,
18.3+/-2.1 ml O(2) per 100 ml). In addition, there was a mild hyperventilation in LR that reduced arterial CO(2) pressure (P(CO(2))) from 39.4+/-0.3 to 37.1+/-1.0 mmHg (P<0.05). These data indicate that the Asian elephant can endure at least short
periods of LR without lowering arterial O(2) content.
