Pulmonary shunting during alveolar hypoventilation in the dog.

abstract：BACKGROUND:Previous studies integrated opioid benefit and harm into one single function-the utility function-to determine the drug toxicity (respiratory depression) in light of its wanted effect (analgesia). This study further refined the concept of the utility function using the respiratory and analgesic effects of th...
