General Anesthesia Flashcards
Irregular respiration
Enhanced reflexes
Disinhibition
Dec awareness of pain
Impaired consciousness
Analgesia
Unconscious
No pain reflexes
Regular respiration
Maintained BP
Surgical anesthesia
Severe respiratory and cardiovascular depression
Medullary depression
Measure of concentration of inhaled anesthetics
Partial pressure or tension
Measure of potency
