9               Factors that must exist
At least one of the following factors must exist before it can be said that, on the balance of probabilities, pulmonary barotrauma or death from pulmonary barotrauma is connected with the circumstances of a person's relevant service:
(1)          experiencing an episode of rapid change in the ambient pressure exerted by an envelope of gas or water surrounding the person whilst:
(a)          descending in an underwater dive;
(b)          surfacing from an underwater dive;
(c)          increasing in altitude whilst flying in an aircraft;
(d)          suffering loss of cabin pressure in an aircraft at altitude;
(e)          decompressing in a hypobaric chamber;
(f)           returning to surface air pressure after being in a hyperbaric chamber including hyperbaric oxygen therapy chambers;
within 24 hours before the clinical onset of pulmonary barotrauma;
(2)          receiving artificial ventilation at the time of the clinical onset of pulmonary barotrauma;
Note: artificial ventilation is defined in the Schedule 1 - Dictionary.
(3)          sustaining a blast injury involving the chest at the time of the clinical onset of pulmonary barotrauma;
(4)          undertaking a Valsalva manoeuvre whilst:
(a)          forcefully vomiting;
(b)          forcefully coughing;
(c)          giving birth;
(d)          performing positive anti-g straining manoeuvre;
(e)          suffering intractable hiccups; or
(f)           weight lifting at a gym;
within 24 hours of the clinical onset of pulmonary barotrauma;
Note: The Valsalva manoeuvre is exhaling air against a closed glottis (airway).
(5)          inability to obtain appropriate clinical management for pulmonary barotrauma before the clinical worsening of pulmonary barotrauma.
