A measuring device includes a measuring part that performs an invasive blood pressure measurement using a transducer and detects that a blood pressure measured by the invasive blood pressure measurement becomes a predetermined abnormal state during the invasive blood pressure measurement, a detecting part that detects whether or not a zero-point calibration of the transducer is being carried out, and a notification control part that controls whether or not to output an alarm based on a detection state of the detecting part when the blood pressure becomes the predetermined abnormal state.

Measuring device, method of measuring blood pressure, and program

A physiological information system includes: a plurality of physiological information sensors configured to acquire physiological information data of a subject being tested, and a physiological information processing apparatus communicatively connected to each of the plurality of physiological information sensors. The physiological information processing apparatus is configured to transmit a synchronous packet toward each of the plurality of physiological information sensors. Each of the plurality of physiological information sensors is configured to: acquire the physiological information data of the subject being tested; receive the synchronous packet transmitted from the physiological information processing apparatus or a trigger signal associated with the synchronous packet; start AD conversion processing for the acquired physiological information data when receiving the synchronous packet or the trigger signal; and transmit the physiological information data converted into digital data to the physiological information processing apparatus.

Physiological information system, physiological information sensor and physiological information processing apparatus

A patient monitor includes an interface configured to be connectable to a first sensor to measure first physiological information and to a second sensor to measure second physiological information, and a controller configured to actuate the second sensor to start a process for measuring the second physiological information in response to the first physiological information turning abnormal, the first physiological information being calculated based on a sensor signal acquired from the first sensor.

Patient monitor

A measuring apparatus includes: a measuring section which performs an invasive blood pressure measurement, and which detects that a predetermined abnormal condition occurs in a blood pressure during the measurement; a detector which detects whether or not a zero point calibration is being executed on a transducer to be used in the measurement; and a notification controller which, in a case where the blood pressure measured by the measuring section is in the predetermined abnormal condition, controls whether an alarm is output or not, based on a detection state of the detector. The notification controller can select a first mode in which an alarm sound is output, or a second mode in which the alarm sound is not output, based on an elapsed time period from a predetermined timing relating to the zero point calibration, and an output from the measuring section.
