Abstract
Disclosed are methods for facilitating medical and/or procedures that are performed without “general anesthesia,” which is also described in the specification as the state of patient “unconsciousness” resulting from a drug administered by an anesthetist or anesthesiologist. The methods safely and effectively provide and maintain drug infusions that do not push the patient into unconsciousness and/or general anesthesia. Methods according to certain embodiments of the invention include the use of parameters and/or values that correlate to drug delivery during a procedure, and a patient health monitor to measure and send signals regarding a patient health condition to a processor.

97. A method for sedating a patient in connection with the patient undergoing one or more medical and/or surgical procedures without general anesthesia, said method comprising:
-
connecting to a patient a drug delivery device capable of controllable drug delivery to the patient during said procedure, said drug delivery device being coupled to a controller which controls the delivery of drugs to the patient;
attaching at least one patient health monitor device to a patient, said health monitor device generating a signal reflecting at least one monitored physiological condition of the patient during said procedure;
delivering one or more drugs to the patient during said procedure with said drug delivery device;
said drug being delivered at a desired supply rate;
sending said signal from said health monitor device to said controller during said procedure, said signal communicating a present value reflecting said monitored physiological condition of the patient;
accessing parameters for said monitored physiological condition, said parameters indicating values for said measurements of said monitored physiological condition where said values correlate to levels of desired sedation during said procedure;
comparing said measurements reflected in said received signal with said parameters; and
modifying said desired supply rate of the drugs as necessary in response to said comparing in order to maintain said patient safely within said levels of desired sedation during said procedure. - View Dependent Claims (98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118)

119. A method of providing sedation without general anesthesia to a non-intubated patient in need thereof during a medical and/or surgical procedure with an electronic drug delivery apparatus, said method comprising:
-
coupling said drug delivery apparatus to said patient;
delivering a sedative drug to said patient with said a controllable drug delivery device, said delivery being at a drug delivery rate sufficient for said patient to approach but not enter general anesthesia during said procedure;
monitoring at least one physiological condition of the patient;
electronically comparing the physiological condition of said patient with information reflecting a safe physiological condition for patients during said procedure, and electronically controlling the drug delivery rate at which said controllable drug delivery device is delivering said drug during said procedure to maintain a safe physiological condition. - View Dependent Claims (120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143)

144. A method of sedation by a non-anesthetist of a non-intubated, patient in need thereof without general anesthesia during a medical and/or surgical procedure, said method comprising:
-
infusing said non-intubated patient in need of sedation during said procedure with a drug dosage that is insufficient to result in general anesthesia;
electronically sensing at least one physiological condition of the patient during said procedure and providing an electronic signal reflecting said condition;
electronically receiving said signal and controlling said infusion in response thereto to sedate said patient effectively without general anesthesia during said procedure. - View Dependent Claims (145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166)

167. A method for sedating or providing pain relief to a patient undergoing a medical and/or surgical procedure without general anesthesia, said method comprising:
-
connecting to a patient a drug delivery device capable of controllable drug delivery to the patient during a procedure, said drug delivery device being coupled to a controller which controls the delivery of the drugs to the patient;
coupling a monitor to the patient;
said monitor providing feedback indicative of the patient'"'"'s effective spontaneous ventilation;
communicating said feedback to said controller;
said controller receiving said sensed data from said sensor and accessing parameters indicating normal feedback ranges for effective spontaneous ventilation during said procedure;
controlling dosage of a delivered drug with said controller so as to maintain effective spontaneous ventilation of said patient; and
recording said feedback and said dosage electronically in a recording device connected to said electronic controller. - View Dependent Claims (168, 169, 170, 171, 172, 173, 174, 175, 176, 177)

178. A method of providing sedation by a non-anesthetist medical personnel to a patient in need of pain relief and/or sedation during a medical and/or surgical procedure, said method comprising:
-
coupling an electronic drug delivery device to said patient and delivering to said patient one or more drugs at a predetermined drug delivery rate to provide sedation;
coupling a monitor to the patient and providing feedback indicative of the patient'"'"'s spontaneous ventilation;
communicating said feedback to a processor connected to said monitor, said processor comparing said signal to parameters that define whether a given patient is spontaneously ventilating effectively while receiving said drug at said drug delivery rate, and said processor generating a signal reflecting the ventilatory status of the patient and indicating modifications of said drug delivery to maintain proper ventilatory functions during said medical procedure; and
using said feedback to control said drug delivery device to maintain effective spontaneous ventilation of the patient. - View Dependent Claims (179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189)
