a) ECG

b) EEG

c) Defibrillator

d) Thermometer

note: please answer it in simple way and i prefer to answer them by computer

Answer 1

The probes used are based upon the different ranges these are given as :

For

a) ECG

We have the input of the probe for further steps

The input is in the range of 1-5 mV

Hence . ECG Probe range is 1 -5 mV

The probe used here is the 12-lead ECG which records the heart's electrical activity as different  waveforms of magnitude and frequency.

b)

EEG

100 microVolts

0.1 - 4 Hz

EEG probes are small metal discs usually made of stainless steel, tin, gold or silver covered with a silver chloride coating. They are placed on the scalp in special positions. These positions are specified using the International 10/20 system. Each electrode site is labeled with a letter and a number .

c)

Defibrillator

Made of polished, surgical-quality stainless steel, these paddles are overmolded with durable plastic. Various sizes are available .

1000 Volts

100 - 200 J for maximum 5 mili seconds

d)

Thermometer Probe is concerned with the temperature

-50 to 400 degree Celsius

3-5 mV
