BAROTRAUMA & DYSBARISMS #8

ARTERAIL GAS EMBOLISM:  (AGE)Most serious of all dive injuries – frequently fatal.
Second only to drowning in fatalities in sport divers.
Ruptured airways allow air bubbles to enter the pulmonary circulation and go to the left side of the heart.
From the left ventricle may migrate to the coronary or cerebral circulation.
Resulting in:
ACUTE MYOCARDIAL INFARCTION (AMI)
CEREBROVASCULAR ACCIDENT (CVA)
AGE usually presents within 10 minutes of the “burst lung”.

SYMPTOMS: 
CVA = neurological symptoms:
change in mood or affect
visual disturbances
hemiplegia or hemiparesis
unconsciousness

AMI = apnea – dyspnea
chest pain – chest pressure
dysrhythmia s – asystole

SUDDEN LOSS OF CONSCIOUSNESS BEFORE SURFACING IS AGE UNTIL PROVEN OTHERWISE

TREATMENT:  RECOMPRESSION!!!
100% O2 while transporting
Transport supine & MONITOR AIRWAY
