Gastric Dilatation-Volvulus

Caudal vena cava occlusion

Diaphragm impingement

Reduced venous return from abdomen to heart

Hypovolemic Shock

Hypotension

Myocardial hypoxia and injury

Arrhythmia

Decrease movement of diaphragm

Low tidal volume

Hypoventilation

Portal Vein occlusion

increased rate of endotoxin released by gram - bacteria

reticuloendothelial system cannot detoxify leading to septic endotoxic shock

Respiratory Failure

Decrease cardiac output

Gastric ischemia

gastritis and gastric necrosis

absorption of bacteria + endotoxin into circulaton

hemorrhage

protein loss

perforation

Hypoperfusion
