General Information And Rules For Use Of The Optional Primedic; Tm Battery Pack - Primedic HeartSave AED Operating Instructions Manual

General information and rules for use of the optional PRIMEDICTM battery pack
Recommended protective distances between portable and mobile HF telecommunication devices and the PRIMEDIC
TM
The PRIMEDIC HeartSave is designed for use in an electromagnetic environment in which the HF interference is
controlled. The customer or user of the PRIMEDIC
the minimum distance between portable and mobile HF telecommunication devices (transmitters) and the PRIMEDIC
HeartSave – independently of the output power of the communication device, as shown below.

For transmitters with a maximum power rating that is not given in the table above, the distance can be determined by
using the equation that belongs to the respective column, whereby P is the maximum power rating of the transmitter in
Watts (W) according to the manufacturer of the transmitter.
NOTE 1 At 80 MHz and 800 MHz the higher frequency range is applicable.
NOTE 2 The ISM frequency ranges (for industrial, scientific and medical applications) between 150 kHz and 80 MHz are
6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz and 40.66MHz to 40.70 MHz.
NOTE 3 The purpose of the concordance levels in the ISM frequency bands between 150 kHz and 80 MHz and 2.5 GHz
is to reduce the probability of mobile/portable communication devices causing interruptions if they are unintentionally
brought into the vicinity of the patient. For this reason the additional factor of 10/3 is applied when calculating the
recommended safety distance in these frequency ranges.
NOTE 4 These guidelines may not be applicable in all cases. The spread of electromagnetic factors is affected by
absorption and reflections from buildings, objects and people.
14 General information and rules for use of the
optional PRIMEDIC
A Nickel-Cadmium battery pack (NiCd battery) has been selected to operate the
PRIMEDIC™ HeartSave, as this type of battery in practise has several advantages over
other types of batteries.
The NiCd battery has a high power density, i.e. with the same physical size, the
PRIMEDIC™ battery can provide much more defibrillation or has longer standby time
than, for example, a comparable lead battery.
Handling the NiCd battery is unproblematic. With a modern, microprocessor controlled
charge switch as used in the PRIMEDIC™ battery pack, it is possible to attain very
short charging times while at the same time, conserving the battery pack.
If the NiCd battery is only slightly discharged and then recharged over a longer period
of time, the typical "Memory" effect occurs. The practical consequence of this
"Memory" effect is that the battery, although it has a large nominal charging capacity,
behaves like a small battery with low capacity.
