anesthesiologists at the university hospital have developed a new device for monitoring anesthesia the risk of waking up during an operation is particularly high when drugs are administered intravenously. one possible reason for this is that propofol concentration in the body cannot be measured yet. but in inhalation anesthetics the so-called blood gas partition coefficient describes this. the fact that the concentration of volatile anesthetics can be measured a measure of the concentration which i didn't have until now with propofol which is why the probability of over and under dosing is higher than with gas anesthetics. for. this new device is intended to remedy the situation the ed measures the concentration of propofol in the patient's body via his breath.
