B30 Patient Monitor
1-4
NOTE:
−
This Monitor conforms to particular safety standard for multifunction patient
monitoring equipment to IEC 60601-2-49 with the exception of Sub- clause
51.103.1: A new technical alarm only triggers a visual indication, not the audible
alarm.
−
During silencing, all new alarms for the same reason and all alarms for a different
reason are indicated only visually.
WARNING In clinical conditions, caregivers are more likely to silence alarms when
they consider these alarms quietly cacophony and may distract and
overwhelm the clinicians. Appropriate visual textual message indicated in
B30 still work to direct the caregiver's attention to the unexpected situation
when alarms are silenced. However, the alarm silence function should be
carefully used, the clinical practitioner should check the monitor’s screen
frequently during silencing.
NOTE:
−
This Monitor conforms to particular safety standard for multifunction patient
monitoring equipment to IEC 60601-2-49 with the exception of Sub- clause
51.102.4: New PHYSIOLOGICAL ALARM(S) beginning after the activation of SILENCE/
RESET resume audio-visual ALARM manifestations
−
Refer to the exception of Sub- clause 51.103.1 for the same performance and
warning.
•
The invasive blood pressure parameter conforms to the IEC 60601-2-34 with the
exception of Sub-clause 51.300 and 51.207.4
NOTE:
−
The invasive blood pressure parameter conforms to the IEC 60601-2-34 with the
exception of Sub-clause 51.300: Both non-latched and latched alarms are
selectable for technical alarms.
−
Refer IEC 60601-2-49 item for monitor’s performance and warnings.

the audible alarm.
−
Refer IEC 60601-2-49 item for monitor’s performance and warnings.
•
The ECG parameter conforms to IEC 60601-2-27 with the exception of Sub-clause
50.102.8 a); 51.103.2; 51.103.3.4; 51.104.1 and 51.104
NOTE:
−
The ECG parameter conforms to IEC 60601-2-27 with the exception of Sub-clause
50.102.8 a): Frequency response: The output signal amplitudes are out of range at
Method A 40HZ and Method B
−
The ECG high-frequency response limit for monitoring filter and ST filter with 50 Hz
power supply frequency is 30 Hz, but not 40 Hz according the 60601-2-27.
WARNING In clinical conditions, the high-frequency response limit of 30 Hz for
monitoring filter and ST filter with 50 Hz power supply frequency is
adequately and safe for these lethal arrhythmia identification which are
available in B30. The diagnostic filter is recommended for diagnostic
purposes.
