individual using oxygen, and the remaining position
serves for testing hose and mask integrity. In the
EMERGENCY position, the control lever causes 100%
oxygen to be delivered at a safe, positive pressure. In the
NORMAL position, the lever allows delivery of normal or
100% oxygen, depending upon the selection of the diluter
control lever. In TEST MASK position, 100% oxygen at
positive pressure is delivered to check hose and mask
integrity.
