persistent tingling in her right arm and leg and right cheek. On the sixth day, she presented to her

Case 11 – Mild neurological symptoms after omitted decompression
resolved completely during recompression.
A 57-year-old male public safety diver with basic open-water certification made a series of two air
dives at an elevation of 1,100 ft (335 m) in a single day for a body recovery. The depths were 91
ffw (28 mfw) and 61 ffw (19 mfw), and the bottom time of the second dive was seven minutes
after which he made a rapid ascent and omitted required decompression but was asymptomatic
at the surface.
Upon awaking the following morning, 16 hours following his final dive, he noted mild right calf
tingling which gradually increased over the next 24-hours to the upper posterior aspect of the
right thigh and persisted for the next four days. On the fifth day, he presented to his local hospital
for evaluation, but the examining physician was unable to elicit any objective findings. The patient
was given surface oxygen for one hour without effect and was treated on a Table 6 without
extensions which resulted in complete resolution of symptoms within 10 minutes during his first
oxygen breathing period. The patient was discharged asymptomatic.
