Risks from Electromagnetic Interference
Radios, cell phones, or other emitters in the immediate vicinity of the unit may affect the safe operation of
the same. For minimum distances from emitting devices see section 16 “Guidelines and Manufacturer’s
Declaration on Electromagnetic Compatibility (EMC)”, page 119.
Electrosurgery units with their high-frequency output voltages can be powerful sources of interference.
Other electromedical units are primarily affected not by emission of electromagnetic waves, as is usually
assumed, but, as described in section 5.1 “Risks from Stray Currents”, page 17, by HF leakage currents
which either spread via the power supply or are derived directly from the patient.
Monitors for vital signs may be affected in a particularly drastic manner. As these systems resume their
normal work after the end of the HF current activation, these brief disturbances will usually be tolerated.
In case of active implants such as cardiac pacemakers there is always the danger of damage or alteration of
the programming with unforeseeable consequences. Therefore, before electro-surgery on patients with
pacemakers a cardiologist should be consulted, and the following rules must be observed:
•
Such patients are to be monitored using suitable technology.
•
A defibrillator as well as an external pacemaker should be kept ready for use.
•
Select the lowest possible output power on the electrosurgery unit.
•
Do not use the active electrode of the electrosurgery unit closer than 15 cm to the implant or its
electrodes.
•
Wherever possible, use bipolar technology.
If the maxium® smart C causes interference with other units, contact the Martin Service Center,
see section 2.2 “Hotline”, page 10.

Risks from Pressure Vessels and Argon Gas Flow
5.6.1
Pressure vessels
Through their high internal pressure and weight, the cylinders in which argon is usually delivered form a
potential source of danger. Toppling or falling cylinders may lead to serious accidents, in particular when
the angle valve is struck off, resulting in uncontrolled pressure release. The safety and work guidelines for
the transport, storage, and setting up of such pressure cylinders, which apply to the other medical gases as
well, must be complied with.
Observe the following rules:
•
Never transport cylinders without protective cap!
After removal, keep the protective cap at a designated place in the vicinity of the pressure cylinder. If
the cylinder is set up on the maxium® smart Cart, it can be placed next to the pressure cylinder on the
floor of the cart.
•
Cylinders must be secured against toppling by suitable means!
When the cylinder is set up in the maxium® smart Cart, it can be secured with the belt provided for the
purpose.
•
Never open the angle valve if there is no pressure reducer connected!
