Patent number: 8463370Abstract: The invention relates to a method for monitoring a condition of a patient under anesthesia or sedation, whereupon one, two, three or more signals are acquired, and the signal(s) represent(s) cardiovascular and/or combined electrical biopotential on skull activity of the patient. From said signal or signals are derived or calculated at least two parameter values related to a quantity like waveform amplitude, waveform periodicity, waveform morphology, waveform variability, energy, power, signal complexity and frequency content. A predetermined mathematical index for probability of patient comfort is used, in which function said parameters are variables, and successively changing probability index values of said mathematical index is calculated.Type: GrantFiled: March 20, 2008Date of Patent: June 11, 2013Assignee: Instrumentarium CorporationInventors: Ilkka Korhonen, Marcus Johannis Van Gils, Markku Paloheimo, Arvi Yli-Hankala, Matti Veli Tapani Huiku

Patent number: 7848795Abstract: The invention relates to a mechanism for determining the depth of sleep of a subject. In order to obtain information about the continuum of the depth of sleep in a user-friendly way without a need for high computational power, EEG signal data is obtained from a subject, REM sleep periods of the subject are detected, and a measure indicative of irregularity in the EEG signal data is derived. Based on the measure and the depicted REM sleep periods, a sleep depth index and state information are produced, where the index is indicative of the depth of sleep of the subject and the state information indicates whether or not the EEG signal data is obtained during a REM sleep period. The detection of the REM periods may be based on a bioimpedance measured from EEG electrodes simultaneously with the EEG measurement or on EOG signal data measured from the subject.Type: GrantFiled: May 22, 2006Date of Patent: December 7, 2010Assignee: General Electric CompanyInventors: Pekka Meriläinen, Markku Paloheimo, Juha Virtanen, Hanna Viertiö-Oja, Petteri Lapinlampi

Publication number: 20100249539Abstract: A method and apparatus for determining an indicator of the level of nociception of a subject are disclosed. A parameter indicative of sympathetical activation in a subject is generated. To tackle inter-subject variability and to maintain low measurement delay with the help of reduced computational effort, changes in the parameter are monitored to detect a stable state of the parameter. Upon detection the stable state, a subject-specific scaling transformation intended to transform the parameter to an index on a predetermined index scale is determined. The scaling transformation is made dependent on at least one value detected for the parameter in connection with detection of the stable state. The scaling transformation is then applied to subsequent values of the parameter, thereby to transform the subsequent values to index values indicative of the level of nociception.Type: ApplicationFiled: March 26, 2009Publication date: September 30, 2010Applicant: The General Electric CompanyInventor: Markku Paloheimo

Publication number: 20080236581Abstract: Method in a patient ventilating system to be used for example in awakening a patient at the end stage of an anesthesia procedure in which a carestation comprising an anesthesia machine is used. The method comprises the steps of setting a target value for the patient end tidal CO2 (EtCO2), and performing increase of the patient end tidal CO2 to the set target value by automatically using a ventilator in the anesthesia machine, and keeping blood oxygenation continuously at a safe level.Type: ApplicationFiled: March 29, 2007Publication date: October 2, 2008Inventors: Borje Rantala, Markku Paloheimo

Publication number: 20080167540Abstract: The invention relates to a method for monitoring a condition of a patient under anesthesia or sedation, whereupon one, two, three or more signals are acquired, and the signal(s) represent(s) cardiovascular and/or combined electrical biopotential on skull activity of the patient. From said signal or signals are derived or calculated at least two parameter values related to a quantity like waveform amplitude, waveform periodicity, waveform morphology, waveform variability, energy, power, signal complexity and frequency content. A predetermined mathematical index for probability of patient comfort is used, in which function said parameters are variables, and successively changing probability index values of said mathematical index is calculated.Type: ApplicationFiled: March 20, 2008Publication date: July 10, 2008Inventors: Ilkka Korhonen, Marcus Johannis Van Gils, Markku Paloheimo, Arvi Yli-Hankala, Matti Veli Tapani Huiku

Patent number: 5482035Abstract: The invention relates to a method for anticipating a change occurring in the condition of a patient's organism before the condition of a patient reaches a critical point, the condition of a patient's organism being monitored by the application of an appropriate measuring method and the determinations according to said measuring method being effected at appropriate time intervals. The measuring results obtained on the basis of effected measurements, the number of which must be at least two, or quantities derived therefrom are utilized for predicting the future development of one or more measuring results and, if a measuring result according to the prediction indicates that a limit value representing a predetermined critical point is reached in the condition of a patient within a predetermined period of time, a warning signal is released indicating that this critical point is being approached.Type: GrantFiled: March 17, 1994Date of Patent: January 9, 1996Assignee: Instrumentarium CorporationInventor: Markku Paloheimo
