Every Six Months; Every 12 Months - GE Healthcare B30 User's Reference Manual

Safety checks for software
The GE Healthcare software design controls include performance of a risk analysis using
methods consistent with ISO 14971 Medical devices - Application of risk management to
medical devices.
The monitor software employs watchdog timers, self-monitoring activities (memory,
communication and sensor checks and so on), and power-on self-diagnostics (for example,
memory checksums). For example, for SpO
sensor and, if excessive sensor current is detected, the message 'Faulty probe' is displayed in
the SpO
removed from the display.

Every six months

Gas calibration
Perform gas calibration for airway gas monitoring according to the instructions in the relevant
section. If gas measurement is in extensive use, calibration is recommended every two
months.
NOTE: Do not wash or disinfect calibration gas sampling lines.
Conditioning the batteries
Condition batteries regularly to maintain after their useful life. This is best done on an external
charger. Condition a battery every six months or when the message 'Replace Battery x'
appears status. You can also check the status through
If you do not have an external charger, proceed according to the following instructions. NOTE:
You cannot condition batteries during patient monitoring. Always disconnect the modules first.
1. Continue normal battery use until the green bar of a battery charge indicator is less than
3/4 of the full height. After this, remove the battery. Continue monitoring with one battery
until its charge is less than 3/4 of the full capacity.
2. Insert both batteries and connect the monitor to the power supply. The monitor starts
charging both batteries, and the capacity indicators scroll accordingly. Keep charging the
batteries until both capacity indicators are full height.
3. Continue charging for another two hours. After this, check that the orange battery LED in
the front panel is no longer on. If it is, continue charging until it goes off.
4. Disconnect the monitor from the power supply and leave it on until the batteries run out
and the monitor switches off. Wait for another 15 minutes.
5. Reconnect the monitor to the power supply and turn it on. Continue charging the
batteries until both capacity indicators are full height and no longer scrolling.
6. Keep charging for another two hours. After this, check that the orange battery LED in the
front panel is no longer on. If it is, continue charging until it goes off to indicate that the
battery conditioning is complete.

Every 12 months

Preventive maintenance check
The annual check according to detailed instructions of the "Technical Reference Manual"
requires trained service personnel and appropriate testing tools and equipment.
Calibration check of temperature, NIBP and invasive blood pressures
Calibration check of temperature, NIBP and invasive blood pressures should be performed at
least once a year by qualified service personnel as a part of the Planned Maintenance, see
"Technical Reference Manual".
