 General anesthesia dramatically alters the function of the respiratory system.

 Changes result from the direct effects of the anesthetic drugs on the respiratory system and the indirect effects of recumbency.

 In the anesthetized recumbent horse, PaO2 can markedly decrease, and arterial CaO2 and DO2 may become critically impaired.These changes are greatest for horses in dorsal recumbency.Recumbency without anesthesia does not impair gas exchange to the same degree, indicating the role of the anesthetic drugs in this process.

 The magnitude of the decrease in gas exchange function of the lung does not vary greatly among anesthetic protocols.
