摘要： A method for calibrating a gas analyzer (1). A gas analyzer is calibrated by measuring the zero level of the analyzer (1). The level of the analyzer is measured, after a preceding reset, whenever a temperature variation (.DELTA.T) of an infrared sensor (14) included in the analyzer (1) or of a component thermally connected in a highly conductive manner thereto exceeds a predetermined threshold value (A), or the temperature variation rate (D) of the infrared sensor (14) of the analyzer (1) or of a component thermally connected in a highly conductive manner thereto exceeds a predetermined limit valve.

摘要： The invention relates to a method and apparatus for temperature compensation in gas analyzer equipment for transient error caused by temperature change. According to the method, a radiation source (1) is used for transmitting electromagnetic radiation through a gas mixture to be analyzed, the intensity of radiation transmitted through the gas mixture being analyzed is detected by means of a thermal detector (4) comprising a radiation detecting sensor element (16) and a reference sensor element (17) for generating an output signal proportional to the concentration of gas being analyzed, the temperature of said thermal detector (4) is measured either directly or indirectly, the measured detector temperature values are recorded as a function of time, and the output signal of the thermal detector (4) is temperature compensated by a correction term dependent on the temperature rate of change (DT) of the thermal detector. According to the invention, the uncorrected output signal V.sub.mass of the thermal detector (4) is temperature compensated by adding a correction term V.sub.comp dependent on the temperature rate of change (DT) of the thermal detector to said output signal.

摘要： A mechanism for authenticating a physiological sensor is disclosed. When a sensor is connected to a monitor, the monitor examines whether a first sensor-specific usage identifier of the connected sensor is consistent with a second sensor-specific usage identifier thereof. The first and second sensor-specific usage identifiers are indicative of the cumulative usage of the connected sensor, but may nevertheless be unequal. The first sensor-specific usage identifier is maintained in the sensor and the second sensor-specific usage identifier in a host memory external to the sensor. The use of the connected sensor is allowed when the examining indicates that the said two identifiers of the connected sensor are consistent, and rejected when the identifiers are inconsistent. The two identifiers are further updated in response to the use of the connected sensor in the patient monitor, thereby to keep the said identifiers consistent and updated for a subsequent use attempt of the sensor.

摘要： The invention relates to a patient monitoring device, especially to a pulse oximeter. For suppressing the effects of an interference source causing adverse modulation in one or more blood related signals input to the device, a power spectrum is derived for each blood related signal and the frequency of an interference source causing unwanted modulation in the blood related signal(s) is identified. A weight function is determined, in which the relative weight of at least one frequency is dampened, the at least one frequency depending on the identified frequency. The weight function is applied to the power spectrum(s), thereby to obtain at least one weighted power spectrum. A blood related parameter of the subject is defined based on the at least one weighted power spectrum.

摘要： A method for controlling alarms in a physiological monitoring apparatus, a physiological monitoring apparatus, and a computer program product for a physiological monitoring apparatus are disclosed. In order to decrease the number of nuisance alarms, the level of a physiological signal obtained from a subject is observed and signal morphology is determined for the physiological signal in response to detecting a change of the level of the physiological signal to a predetermined value range representing low signal values, thereby to obtain reference morphology for the physiological signal. Signal morphology is monitored if the physiological signal remains in the predetermined value range and alarms are suppressed as long as the signal morphology fulfills predefined criteria with respect to the reference morphology and the level of the physiological signal remains in the predetermined value range.

The apparatus comprises a sampling element having a wall which a compound to be analyzed is capable of penetrating. The apparatus also includes a pressure-difference producing element which, through the action of a pressure-difference, is capable of delivering a sample along a tube extending from the sampling element. The apparatus also includes an analyzer capable of performing an analysis on a sample drawn from the sampling element. The analyzer is in flow communication with the sampling element by way of the tube. According to the method, a mixture consisting of a medium and a compound drawn from the organ is delivered to the analyzer for a subsequent analysis, and at least some of the mixture is returned from the analyzer back to the sampling element.
