Abstract: Herein disclosed is a monitor, including: a measurement section that acquires measured values of a plurality of parameters showing a health state of a living body; a classification setting section that classifies a relationship among the measured values of the plurality of parameters into a plurality of types of detection states; a status setting section that respectively assigns any of a plurality of types of alarm statuses to the plurality of types of detection states; a state specifying section that specifies one of the plurality of types of detection states on the basis of the measured values acquired by the measurement section; and an annunciation section that outputs an alarm corresponding to the alarm status assigned to the specified detection state.

Abstract: A biological information monitoring apparatus operable to receive biological information measured by a detector adapted to be attached to a patient, and operable to display the biological information on a display, includes: a first display controller which displays an alarm on the display; and a second display controller which displays, on the display, first information which responses to the displayed alarm.

Abstract: A biological parameter displaying apparatus includes: a coordinate displaying unit which displays first coordinates in which a first biological parameter of a patient, which is measured by a first measuring unit, is set as an X-axis, and a second biological parameter of the patient, which is different in kind from the first biological parameter and which is measured by a second measuring unit, is set as a Y-axis; a plot data producing unit which produces first plot data, each of the first plot data being produced based on first measurement values of the first and second biological parameters which are measured at a same time or in a same time zone; and a plot displaying unit which plots the first plot data in the first coordinates.

Abstract: A biological information monitoring apparatus operable to measure biological information of a patient by detecting a biological signal of the patient, and operable to output an alarm, includes an alarm controller which changes the alarm. The alarm includes a first alarm of a first priority and a second alarm of a second priority. When a first condition is satisfied, the first alarm is output. When a second condition is satisfied after the first alarm is output, the alarm controller changes from the first alarm to the second alarm to be output.

Abstract: A biological signal measuring apparatus includes: a pressure sensor which measures a pressure in a living body; a respiratory sensor which measures respiratory information; and an outputting unit which detects an end-tidal based on the respiratory information measured by the respiratory sensor and which outputs a pressure value based on the pressure measured by the pressure sensor when detecting the end-tidal.

Abstract: A stimulator is adapted to electrically stimulate a muscle of a patient. A detector is adapted to detect a response of the stimulated muscle. A processor is operable to obtain a plurality of parameters indicative of muscle relaxation of the patient based on the detected response. A display is operable to display the parameters simultaneously while showing chronological changes thereof.

Abstract: An internal pressure measuring catheter is constituted by at least three lumens which are: an internal pressure measuring lumen whose distal end is open and whose proximal end is connected to an internal pressure measuring transducer; a position correcting liquid-charged lumen whose distal end is closed, in which a liquid is charged, and whose proximal end is connected to a liquid pressure measuring transducer; and a position correcting atmosphere-opened lumen whose distal end is closed and whose proximal end is open to the atmosphere. The adjoining surfaces of the distal end portions of the liquid-charged and atmosphere-opened lumens have a small hole through which the charged liquid can be brought into contact with the atmosphere through the atmosphere-opened lumen.

Abstract: Pressure measuring lumen allows a coarse pressure value of a subject to be read. A liquid filled lumen is allowed to pressure communicate with an atmosphere adjacent to a patient, through the use of a membrane and an atomosphere-opening lumen. A liquid pressure value read from the liquid filled lumen is used to adjust the pressure value to compensate for pressure changes induced by a positional change of the subject.
