Abstract
A drug administration controller has a sensor that generates a sensor signal to a physiological measurement device, which measures a physiological parameter in response. A control output responsive to the physiological parameter or a metric derived from the physiological parameter causes a drug administration device to affect the treatment of a person, such as by initiating, pausing, halting or adjusting the dosage of drugs administered to the person.
Claims14
A drug administration method comprising:
- measuring at least one physiological parameter with a noninvasive optical sensor attached to a patient;
- deriving at least one parameter trend for each measured physiological parameter, the trend indicating if the at least one parameter for each measured physiological parameter is increasing or decreasing at a certain rate over a certain time;
- and
- controlling a drug administration device based at least on one of the at least one parameter trends,
- wherein the at least one physiological parameter includes perfusion index.

A drug administration controller comprising:
- at least one noninvasive optical sensor that generates at least one sensor signal in response to a physiological state of a living being;
- at least one physiological measurement device that generates measurements of at least one physiological parameter in response to the at least one sensor signal, said at least one physiological parameter including perfusion index;
- a rules-based processor that generates a control output in response to at least trends of the physiological parameter measurements, the trends indicating if the physiological parameter measurements are increasing or decreasing at a certain rate over a certain time;
- and
- a drug administration device responsive to one or more control outputs so as to affect the treatment of the living being including at least one of initiating, pausing, halting or adjusting the dosage of administered drugs.
