a. Calculate the CMRR (in dB) of an EEG machine if the EEG output is 1.8 Vp.p (to a 100 jiVp-pEEG input) and the noise output is 0.02 mVp-p(to a 100 liV P-P noise input). b. Calculate the current density generated by an electrosurgery machine at 50W power if the current is dissipated in 0.5 m3 of tissue that has a resistivity of 1800 Qm? c. For a defibrillator to be capable of charging up to 3000 V and releasing 200 J of energy, what size capacitor is needed for the defibrillator design? d. Differential pressure transducer can be used to measure 1-minute volume. Sketch the apparatus and explain how this can be achieved. e. A patient recorded these respiratory measurements: tidal volume is 450 mL, inspiratory reserve volume is 2200 mL and expiratory reserve volume is 850 mL. The total lung capacity of the patient is 4650 mL and the functional residual capacity is 2000mL. Find the residual volume of this patient. f. A mass of oxygen gas occupies a volume of 5 L at 120°C. Calculate its volume when the temperature is reduced to 35°C. a.
