The power transmission and conversion system of a ventilator is defined as which of the follow-ing?
 
  a. A mechanical device that produces gas flow to the patient.
  b. An electrical motor that is connected by a special gearing mechanism.
  c. The system that interprets the settings and produces or regulates the desired output.
  d. Internal hardware that changes electrical or pneumatic energy into mechanical en-ergy.

Question 2

A patient being transferred from a hospital to a skilled nursing facility requires mechanical venti-lation with a fractional inspired oxygen (FIO2) of 0.21. The skilled nursing facility has no piped in gases.
 
  Which of the following ventilators will be able to function in the skilled nursing facility without any extra equipment?
  a. Servoi
  b. LTV 1000
  c. Bird Mark 7
  d. Bio-Med MVP-10

Answer to Question 1

ANS: D
The power transmission and conversion system changes the energy from the power source into mechanical energy. The linear drive piston is a mechanical device that produces gas flow to the patient. The drive mechanism is an electrical motor that is connected by a special gearing mecha-nism. It is the control system that interprets the operator settings and produces or regulates the desired output.

Answer to Question 2

ANS: B
The type of ventilator that will be appropriate for this situation is one that is electrically con-trolled and powered with a built-in air compressor. The LTV 1000 fits this description. The Ser-voi requires both a high-pressure gas source and electrical power. The Bird Mark 7 is a pneumatic ventilator and will not be able to function in this situation. The Bio-Med MVP-10 is also a pneu-matic ventilator that won't function in this situation.
