Medical Gas Connections and Pressure Regulators Quiz

The oxygen therapy unit consists of two main components: an oxygen cylinder and a regulator.

Oxygen therapy is only administered to assist with a casualty's breathing in Western Canada mine rescues.

Hydrostatic testing is not required for oxygen cylinders of any size.

A five-pointed star stamped at the top of the cylinder indicates that the hydrostatic test date can be extended by an additional five years.

In all jurisdictions, oxygen therapy is a mandatory part of first aid training.

Oxygen under high pressure can increase the flash points and ignition temperatures of petroleum products.

Medical-grade oxygen is supplied as a liquid instead of a compressed gas.

Medical oxygen cylinders should not be stored in a cool, well-ventilated place.

The sizes of oxygen cylinders include A, B, and C.

All cylinders should undergo hydrostatic testing as per the manufacturer's specifications.

All oxygen cylinders must be equipped with a pin-indexed medical post outlet.

When transporting cylinders, they do not need to be secured and capped.

The regulator assembly reduces the pressure of oxygen to between 30 and 60 psi.

Adaptors are not available to connect threaded and yoke-type connections together.

Using adaptors to fit a yoke-type regulator assembly onto a threaded cylinder is not recommended in a major emergency situation.

All oxygen delivery masks require extensive training except the one-time-use simple mask.

To use the CAREvent device for oxygen therapy, different steps need to be followed compared to a normal oxygen therapy unit.

The delivery hose and mask used with the normal oxygen therapy unit are not compatible with the CAREvent regulator.

One of the steps to administer oxygen is to ensure that there is a smoking area nearby.

After opening the cylinder valve gently and slowly, it is recommended to turn the flow control to the maximum flow rate.

It is important to ask the casualty about their experience with oxygen therapy before administering it.

All casualties requiring oxygen therapy should receive oxygen at a constant flow rate of 5 litres per minute.

Clearing any foreign material from the hose and mask is not necessary before administering oxygen.

Once comfortable with the mask, the elastic strap should not be placed behind the casualty's head.

An 'E' cylinder contains 3,540 liters of oxygen.

The 'K' cylinder can last for 17 hours and 30 minutes at a flow rate of 6 Lpm.

At 10 Lpm, an 'M' cylinder can last longer than an 'E' cylinder at the same flow rate.

An 'E' cylinder at 6 Lpm can last for more than 2 hours.

At a flow rate of 8 Lpm, a 'K' cylinder can last for less than 5 hours.
