caused by gradient of low pressure pulmonary venous system (hypovolemia) and\/or increased airway pressure (PPV, cough, tension pneumo)<\/p>\n
<\/p>\n
2 cc of air injected into the cerebral circ can be fatal<\/p>\n
1 cc of air in the pulm vein can cause cardiac arrest<\/p>\n
<\/p>\n
injuries close to the hilium yield the highest risk b\/c the pulm vein (low pressure) is close to the large airways<\/p>\n
<\/p>\n
Probe positive PFO can allow conduit from venous air embolism<\/p>\n
<\/p>\n
paradoxical embolism can also occur in ARDS, pulm htn,<\/p>\n
ability of lungs to function as filter is exceeded at 0.35 cc of air per kg per minute<\/p>\n
<\/p>\n
blast injury can cause massive air embolism<\/p>\n
<\/p>\n
hemoptysis with circulatory and CNS dysfunction is sufficient for provisional diagnosis<\/p>\n
<\/p>\n
fundoscopic exam may reveal air in retinal vessels<\/p>\n
<\/p>\n
TEE can detect extremely small bubbles<\/p>\n
<\/p>\n
tympanic membrane should rupture if lung ruptures in blast injury<\/p>\n
<\/p>\n
spont vent is preferred, lung isolation if only one lung injured and ppv is necessary<\/p>\n
<\/p>\n
thoracotmy with hilar clamping has been used<\/p>\n
<\/p>\n
hyperbarics for SAE<\/p>\n
<\/p>\n
HFOV is preferred mode if there is bronchopleural fistula<\/p>\n
