Peter Safar, MD

6. Despite advances in medical science
Sudden Death continues to increase
Advances in modern medical science (including
Emergency Medical Services) have helped to prolong
life and reduce the number of deaths from many “killer”
health problems. But the problem of sudden cardiac
death has continued to go virtually unchecked.

7. BUT THANX TO BIOMEDICAL

What you cannot measure you cannot control

22. Electrical safety testing
It is essential to ensure safe
operating standards for any
product that uses electricity.

a product to conform
to safetystandards pro
mulgated by safety and standard
agencies such as
UL, CE, VDE, CSA, BSI, CCC and
so on.

23. ELECTRICAL SAFETY TESTS

tests such as the high voltage test (also called as Dielectric
voltage-withstand test or high potential test),
 Mains Voltage
 Dual Lead Voltage
 Dual Lead Leakage
 Current Consumption
 Insulation Resistance Test,
 Ground (Earth) Bond & Ground Continuity Test & Leakage
Current Test (also called as Line Leakage Test, Earth

32. Effects of Electric
Current on Human
Body

33. Effects of Electric Current on Human
Body
•Threshold of perception of electric
shock is about 1mA
•Tingling sensation is felt when
contacted with electrified object
through intact of skin
•As magnitude of alternating current is
increased
– Tingling sensation leads to
contraction of muscles
– Muscular contraction increases
– Finally value of current is
reached where grip of current
cannot be released

34.  Let -go- current: the max. current at which the subject
is still capable of releasing a conductor by using
muscles
 Here individual can withstand with no serious effects
 Average let go current for males- 16mA, females-10.5mA,
approx. 9-6 mA for both.
Hold-on-type: A current level higher than let go
current, the subject looses ability to control his own
muscle action and unable to release grip on the
conductor
 Such currents are very painful and hard to bear
 Physical injury is caused b currents in range of 20-100mA
A very high currents (6 amperes and above) lead to
 Temporary respiratory paralysis
 Serious burns

35. Recommendations of IEC
International Electrotechnical
Commission (IEC) said:
 Continuous medical equipment current
should not exceed 100 uA
 Should be with in a frequency range of 0
to 1kHz
 In abnormal situations recommended
max. current is 500 uA
 Should be in a frequency upto 1 kHz
 Above 1 kHz max increases is
proportionally with frequency
