SPYDA BIBS A robust oxygen mask for use in dry hyperbaric enviroments The SPYDA BIBS (Built in Breathing System) is designed to supply pure oxygen during therapeutic treatment in a hyperbaric chamber. It can also be utilised to provide an emergency breathing gas source should the chamber environment become chemically contaminated or experience a fire. It is an ‘overboard dump’ style BIBS; it has both supply and exhaust hoses. Exhaled gas is piped to the outside of the chamber thus preventing the potentially hazardous build up of oxygen which occurs when single hose units are installed. An increase in oxygen level above 21% equivalent at atmospheric pressure (0.21 bar ppO2) within a hyperbaric chamber can be a fire risk, and can also be detrimental to the health of the patient/diver if long exposure is experienced. The main use of BIBS masks is for therapeutic decompression commencing at 18m. The Spyda unit has been optimised to offer minimum breathing resistance at relatively low rates of breathing and shallow depths associated with this procedure.

Robustness and Practical Design Users are now demanding equipment that can withstand the bumps, bangs and physical abuse from day to day operations, yet still deliver first rate performance. The advanced polymer used for the main body is extremely robust and will undoubtedly provide longevity in service. The oral nasal is easy to remove and replace. This permits divers to have their own oral nasal, or otherwise permit easy biological decontamination. Testing The Spyda BIBS have been extensively tested and fully comply with ABS (American Bureau of shipping) standards under their latest rules for...
