Oxygen is stored in ___?___ tanks

Nitrous oxide

Essential Components of Anesthesia: 1. Analgesia - perception of pain eliminated 2. Hypnosis - unconsciousness 3. Depression of spinal motor reflexes 4. Muscle relation 5. Respiratory depression

Lipid Theory

Protein (Receptor) Theory

Binding theory

Phermacokinetics of lnhaled Anesthetics is dependent on: 1. Amount that rarches the brain 2. Partial Pressure of anesthetics 3. Solubility of gas into blood (blood:gas solubiliry coefficient) 4. Cardiac Output
