What are the Problems Associated with Severe Acute Respiratory Syndrome (SARS) in a Naval Diver?

Research Paper Title

Severe acute respiratory syndrome in a naval diver.

Abstract

Severe acute respiratory syndrome (SARS) is a highly infectious, rapidly progressive, emerging disease.

Early diagnosis and preventive measures are key for treatment and minimization of secondary spread. In the context of the armed forces, aggressive containment measures are essential to prevent an outbreak.

In this study, the researchers present the first reported case, to their knowledge as of 2006, of SARS in a naval diver. The special physical requirements for divers and the potential complications associated with deep sea diving necessitate extensive investigation before certification of fitness for diving after SARS.

In the early recovery period, potential problems during diving are caused by inadequate lung ventilation in relation to exercise level and increased breathing resistance attributable to weak respiratory muscles, with corresponding risk of hypoxia and hypercapnia, as well as decreased ability to respond to non-respiratory problems during diving.

Problems in the late recovery period include increased risk of diving complications (such as pulmonary barotrauma) resulting from fibrosis and scarring within the lung parenchyma, which are known complications of SARS.

From their experience, the researchers suggest that computed tomographic scans of the thorax, lung function tests, and careful follow-up monitoring should play a vital role in the assessment of patients during the convalescent period, before certification of fitness to dive.
