A measuring apparatus comprising: a measuring section which is configured to perform an invasive blood pressure measurement, and which is configured to detect that a predetermined abnormal condition occurs in a blood pressure during the invasive blood pressure measurement; a detector which is configured to detect whether or not a zero point calibration is being executed on a transducer that is to be used in the invasive blood pressure measurement; and a notification controller which, in a case where the blood pressure measured by the measuring section is in the predetermined abnormal condition, is configured to control whether an alarm is output or not, based on a detection state of the detector, characterised in that the notification controller is configured to select a first mode in which an alarm sound and an alarm message are output, a second mode in which the alarm sound is not output and the alarm message is output, or a third mode in which an alarm sound and an alarm message are 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, the elapsed time period has an initial set time period, a first set time period which is after the initial set time period, and a second set time period which is after the first set time period, the notification controller is configured to select the third mode during the initial set time period, and in a case where, at a timing of the first set time period, a blood pressure under measurement is lower than a first set value, the notification controller is configured to select the first mode, in a case where, at a timing of the first set time period, the blood pressure under measurement exists between the first set value and a second set value which is larger than the first set value, the notification controller is configured to select the second mode. a measuring section which is configured to perform an invasive blood pressure measurement, and which is configured to detect that a predetermined abnormal condition occurs in a blood pressure during the invasive blood pressure measurement; a detector which is configured to detect whether or not a zero point calibration is being executed on a transducer that is to be used in the invasive blood pressure measurement; and a notification controller which, in a case where the blood pressure measured by the measuring section is in the predetermined abnormal condition, is configured to control whether an alarm is output or not, based on a detection state of the detector, characterised in that the notification controller is configured to select a first mode in which an alarm sound and an alarm message are output, a second mode in which the alarm sound is not output and the alarm message is output, or a third mode in which an alarm sound and an alarm message are 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, the elapsed time period has an initial set time period, a first set time period which is after the initial set time period, and a second set time period which is after the first set time period, the notification controller is configured to select the third mode during the initial set time period, and in a case where, at a timing of the first set time period, a blood pressure under measurement is lower than a first set value, the notification controller is configured to select the first mode, in a case where, at a timing of the first set time period, the blood pressure under measurement exists between the first set value and a second set value which is larger than the first set value, the notification controller is configured to select the second mode. <EOS>
