Question
1. Volume cycled ventilator has the throwback of:
(A) Potential hyper or hypoventilation
(B) May lead to excessive inspiratory pressure
(C) Guarantees the delivery of pre-set tidal volume
(D) Allows limitation of peak inspiratory pressure
2. Which of the following is not true?
(A) A hand accident touches a faulty device with leaking voltage/current is a macroshock
(B) Putting the phone charger into mouth will induce macroshock
(C) Macroshock is often associated with power distribution
(D) Electrical safety for macroshock is about the current path to the ground
3. What of the following is not true?
(A) Cardiac resynchronization therapy is also called bi-ventricular pacing. It has two pacing leads to pace left ventricle and right ventricle
(B) Pulsatile left ventricular assistant device is the clinical standard. It mimics the heart pump and generates detectable pulse waves
(C) DDI mode is better than DDD mode for patients with ventricular fibrillation
(D) Current is what actually defibrillates the ventricular fibrillation
Explanation / Answer
1.
B) The advantage of Assist control volume ventilation is guarantees delivery of set tidal volume (the amount of air delivered with each breath) and
Assist control (AC) volume ventilation may lead to excessive inspiratory pressures,it is a drawaback of volume cycled ventilator
2.
A) A hand accident touches a faulty device with leaking voltage/current is a macroshock
Macroshock is externally applied current spreads through out the body and Microshock is all the current applied
through an intracardiac catheter flows through the heart.
3.
B) Pulsatile left ventricular assistant device is the clinical standard. It mimics the heart pump and generates detectable pulse waves
