1- Which of the following is true about anesthesia machine ?
- Desflurane vaporizer is heated to 39 C
- Halothane vaporizer at 39 C
- Rotameter is a variable pressure flow meter and variable orifice device for gases only
- O2 sensor is attached to inspiratory limb at the machine end
- Sodium hydroxide
- Barium hydroxide
- Calcium hydroxide
- Potassium hydroxide
- Rotameter reading may not affected by dirt inside the tube
- Rotameter reading may not get affected by static electricity
- The height to which bobbin rises indicates the flow rate
- A rotameter is variable pressure flowmeter
- Flow rates can be calculated
- Gives false high values at low flow rates
- Gives false low values at high flow rates
- Used for calculation of expired volume
- Reads bidirectional flow
- Cylinder is a part of high pressure system
- O2 flush delivers < 35 liters
- O2 flush delivers > 35 liters
- Pipelines is a part low pressure system
- Location of oxygen valve after the nitrous oxide valve
- Presence of a pin index system to prevent wrong attachment of the nitrous oxide and oxygen cylinders
- Location of a fail-safe valve downstream from the nitrous oxide supply source
- Incorrect attachment of anesthesia machines.
- Incorrect attachment of anesthesia face masks.
- Incorrect inhalational agent delivery
- Incorrect gas cylinder attachment
- 2, 5
- 1, 5
- 3, 5
- 2, 6
- Pin is present on cylinder
- Pin is present on machine
- Not effective if wrong gas is filled in cylinder
- Pin index of air is 2, 5
- Hole positions on cylinder valves
- O2
- CO2
- N2O

- Black cylinders with white shoulders
- Black cylinders with grey shoulders
- White cylinders with black shoulders
- Grey cylinder with white shoulders
- Pressure is 2200 psig
- Blue in color
