spirometer and the other to the water tap. Fill the flask to the mark and air will be
despatched from the flask into the spirometer. Close the clip and empty the flask.
10. A second line or reading should appear above zero volume line which should provide
a scale e.g 500ml air volume = height ?mm. This is the basis for defining the scale.
11. Set the valve to SPIROMETER and adjust the weight so that the float comes to rest
in the mid position.
12. If oxygen consumption is to be measured fill the nylon net bag with coarse soda
lime and place it in the container (front view, right hand side of the tank, unscrew
the wing nut and remove the cap).
13. Ensure there are no gaps between the net bag and the walls of the container.
Replace the cover and tighten.
14. Gently press down on the float to expel the air and turn the valve to ATMOSPHERE.
15. Connect the medical grade oxygen supply to the oxygen inlet (container, adjacent
to the wing nut tube) using pressure tubing.
16. Slowly turn on the oxygen supply. Oxygen will flow into the unit and raise the float.
When it contains about 2 litres turn off the supply set the valve to SPIROMETER and
press down on the float. This forces the oxygen out through the mouthpiece and
flushes the air out of the system. Do not allow oxygen to be discharged near a naked
flame.
17. Repeat the process, filling and flushing and then close off the oxygen supply and
turn the valve to ATMOSPHERE. If the cylinder is to be removed ensure a tube and
clip are left closing the oxygen inlet.
OPERATING INSTRUCTIONS
1. A two way valve is fitted. When this valve is set to ATMOSPHERE the breath-
ing tubes are open to the atmosphere and the spirometer is closed. The subject
therefore breathes normal atmospheric air. This position should be used when the
subjects first use the spirometer to enable them to become accustomed to it.
2. When the valve is set to SPIROMETER the subject takes in the oxygen contained
under the float, causing the float to fall. The expired gases pass through the soda
lime contained before returning to the float. The soda lime absorbs the carbon di-
oxide from the expired gases. The valve is set to this position when the spirometer
is in normal use.
Medical grade oxygen cylinder must only be used for respiration
purposes. Before using soda lime dust should be removed from it by
pouring the soda lime from one container to another in the open air.
