The invention relates to a control device for controlling the administration of propofol to a patient according to the preamble of claim 1 and to a method for controlling the administration of propofol to a patient according to the preamble of claim 4. With a method of this kind a bispectral index (BIS) target value is set which shall be, at least approximately, reached within a patient. A controller then computes a recommended infusion rate of propofol based on the target BIS value and further based on a measured propofol level of the patient for administering propofol to the patient. The controller herein comprises a model unit for computing the recommended infusion rate such that, using the model unit for determining the propofol sensitivity of a patient by means of a mathematical model taking into account the bispectral index (BIS) value and optionally the measured propofol level as input variables, the recommended infusion rate for administering propofol to the patient to achieve the BIS target value may be determined.

An index output device for appropriately evaluating the conditions of the patient under anesthesia. An index output device 100 includes an electric stimulation section 170, an acquisition section 180, a calculation section, and an output section. The electric stimulation section 170 is configured to apply an electric stimulus to a living body. The acquisition section 180 is configured to acquire a plurality of physiological responses from the living body in response to the common electric stimulus applied to the living body by the electric stimulation section 170. The calculation section is configured to calculate, from the plurality of responses of the living body acquired by the acquisition section, an index related to a level of muscular relaxation (TOF) and an index related to a level of analgesia (PIR). The output section is configured to output the indexes calculated by the calculation section.

An anesthesia ventilator, for the automated ventilation of a patient, includes an expiratory port and an inspiratory port for connecting a ventilation tube facing the patient for a breathing gas, a breathing gas delivery unit, at least one breathing gas sensor for detecting an anesthetic gas concentration, at least one pressure sensor for detecting a pressure of the breathing gas, as well as at least one computer. The computer is configured to actuate the breathing gas delivery unit as a function of the detected pressure of a preset desired pressure value. The computer is further configured to perform an adaptation of the desired pressure value as a function of the detected anesthetic gas concentration.

Method and systems are provided for monitoring neuromuscular blockade in patients during surgical procedures. The system and method utilizes a stimulator to provide stimulation to a nerve of the patient, such as train-of-four (TOF). Following such stimulation, the system and method monitors for muscle twitch reaction and, based upon the monitored muscle twitches, the system and method creates a neuromuscular blocking trend curve. The neuromuscular blocking trend curve provides an estimated time of recovery for the patient and provides the estimated recovery time to a clinician. The estimated recovery time allows the clinician to modify treatment of the patient to accelerate recovery if required.

A system for measuring a gas concentration, the system including: a first oscillator including a first surface for placement in a sampling location, wherein the first oscillator oscillates at a frequency greater than 20,000 Hz but less than 300,000,000 Hz; a first counter to accumulate a count of oscillations of the first oscillator; and a comparator to calculate a difference between the accumulated counts of the first oscillator and a reference, wherein the difference calculated by the comparator is sampled at a frequency of less than 100 Hz.

Methods are disclosed for determining a prognosis of a test patient following or during a surgical procedure. In some embodiments, the disclosed methods comprise forming a test data vector characterizing concurrent measures of mean arterial pressure (MAP), bispectral index (BIS), and standard minimum alveolar concentration (MAC) of the test patient from sequential time intervals during the surgical procedure. A K-means clustering procedure is performed on the test data vector and a plurality of reference data vectors characterizing concurrent MAP, BIS, and MAC measures for sequential time intervals during surgical procedures from reference patients with known clinical outcome. A prognosis of one or more post-surgical outcomes of the test patient is determined based on the known surgical outcome of reference patients in the cluster including the test data vector.

A method of monitoring respiration with an acoustic measurement device, the acoustic measurement device having a sound transducer, the sound transducer configured to measure sound associated with airflow through a mammalian trachea, the method includes correlating the measured sound into a measurement of tidal volume and generating at least one from the group consisting of an alert and an alarm if the measured tidal volume falls outside of a predetermined range.

A system and method for monitoring a patient suspected of experiencing a state of unconsciousness are provided. In certain aspects, the method includes assembling physiological data, obtained from a plurality of sensors placed on a subject, into sets of time-series data, separating, from the sets of time-series data, a plurality of electroencephalogram signals, and determining, from the plurality of electroencephalogram signals, at least one of frequency information and amplitude information. The method can also include identifying, using the at least one of the frequency information and the amplitude information, spatiotemporal signatures indicative of a likelihood of arousing the patient to consciousness by applying an external stimulus and generating a report indicating the likelihood of arousing the patient to consciousness by applying the external stimulus.

The present disclosure includes a medical monitoring hub as the center of monitoring for a monitored patient. The hub includes configurable medical ports and serial ports for communicating with other medical devices in the patient's proximity. Moreover, the hub communicates with a portable patient monitor. The monitor, when docked with the hub provides display graphics different from when undocked, the display graphics including anatomical information. The hub assembles the often vast amount of electronic medical data, associates it with the monitored patient, and in some embodiments, communicates the data to the patient's medical records.
