Brief summary
Chart review of patients who received hyperbaric oxygen therapy for cerebral decompression illness who also underwent SPECT brain blood flow imaging to see if SPECT brain imaging tracks and is consistent with the clinical condition of the patients.
Detailed description
SPECT brain imaging has been shown to be the most sensitive imaging modality for cerebral decompression illness. This study is a retrospective review of the PI's experience using SPECT brain imaging in the diagnosis and treatment of all phases of cerebral decompression illness over the past two decades. The purpose of the study is to see if the functional imaging is consistent with the clinical condition and cognitive testing. Chart review of symptoms, and physical exam findings will be compared before and after treatment to SPECT brain imaging radiological readings to assess concordance.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| SPECT brain imaging | Within one month after completion of hyperbaric oxygen therapy | Comparison of SPECT brain imaging chart copy of radiological reading before or early in the treatment history to SPECT brain imaging chart copy of radiological reading after treatment. Imaging will be scored as better, worse, or no change based on resolution of defects or improvement in pattern of injury. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Symptoms of cerebral decompression illness | Within one month after hyperbaric oxygen therapy | Chart reports of patients' symptoms of cerebral decompression illness before hyperbaric oxygen therapy will be compared to symptoms after hyperbaric oxygen therapy and rated as better, worse, or no change. |
| Abnormal physical exam findings | Within one month after hyperbaric oxygen therapy | Chart reports of abnormal physical exam findings before hyperbaric oxygen therapy will be compared to chart reports of physical exam findings after hyperbaric oxygen therapy and rated as better, worse, or no change. |
