Fig. 1. A sample recording of the variations in intra-abdominal pressure (IAP),
central venous pressure (CVP) and total post caval vein blood flow
(
PC) during
ventilation (A) at rest and (B) running at 1.0 km h–1. During
expiration (Exp), IAP falls to near atmospheric pressure, and
PC increases. Peak
IAP and CVP and minimum
PC occur at the end
of inspiration (Insp). Inspired tidal volume was twofold higher during
exercise (46.23 ml kg–1) compared with rest (24.68 ml
kg–1). Buccal oscillations (movement of air in and out of the
buccal region) occur in alligators but do not contribute to gas exchange. Data
are from one alligator (mass 3.6 kg) and are representative of the trend in
all alligators tested. Scale bar in A, 15 s; B, 5 s.
