Question 3

Which of the following is FALSE when discussing flowmeters?

1. A flowmeter controls the rate at which a specific gas is delivered.
2. The oxygen flowmeter should always be first (upstream) in the series of flowmeters to help prevent the delivery of a hypoxic mixture.
3. Flowmeter tubes are gas specific.
4. Excessive torque should be avoided when closing flowmeters.

Answer 3

2. The oxygen flowmeter should always be first (upstream) in the series of flowmeters to help prevent the delivery of a hypoxic mixture.
