The topic of gas emboli is miscellaneous enough to be fitted into the "misc" section of SAQs. The most likely causes include surgical mishaps, particularly cardiothoracic (and so it could have easily slotted into the cardiothoracic ICU section). If discussion were limited to cerebral arterial gas embolism, it could be classified as a predominantly neurological issue and parked in the neurology/neurosurgery section. These would be logical options. However the author of Deranged Physiology is unencumbered by logic, and had instead opted to put gas emboli into the Trauma/ Drowning section, as by far the most interesting cause of such emboli is decompression injury, and because it allows him to digress extensively on the topic of exposing humans to pressurised gas.
