Hello readers:
ER Problems
In the years that I have edited this forum, the major difficulty that I have noted with ERs is that a misdiagnosis results and time is lost. As several responders noted, most physicians are not versed in the vagaries of DCS and problems result.
What Divers Know -- Or Should Know.
Certainly you can get DCS if you are within the tables. If the dive was really trivial and the gas loads were negligible (let us say, at most 2/3 of the NDL), then one should have a high index of suspicion that we are more likely than not dealing with a sprain or over exertion.
Doppler monitoring has shown that few bubbles are detectable in the blood about one hour post dive. Doppler ultrasound is not used to diagnose DCS unless the pain has just appeared. [It is most successful in laboratory settings.] A blood draw will likewise almost never have bubbles present. It is common lore, however, that the bends are the result of gas bubbles in the blood of a diver.
That is a big mistake but not an uncommon one. :nonono:

- Divers will be told that they do not have DCS because they were within the table limits.
- Divers will have their blood drawn, and DCS will be excluded as a diagnosis, because bubbles are not present in the blood sample.
