When diving with an enriched air computer, what is essential to remember about oxygen exposure limits?

When diving with an enriched air computer, it is essential to remember that oxygen exposure limits are absolute limits not to be exceeded. This is crucial because exceeding these limits can lead to oxygen toxicity, which can have serious and potentially life-threatening consequences. Oxygen toxicity can affect the central nervous system and cause symptoms such as visual disturbances, nausea, irritability, twitching, and even seizures at higher concentrations or prolonged exposures.

Enriched air dive computers are designed to help divers manage their exposure to oxygen by providing data on their dive profiles, including the percentage of oxygen in the gas mixture being used. These computers take into account factors such as the depth and duration of the dive, and they will alert divers when they approach the maximum allowable oxygen exposure limits.

Understanding that these limits are absolute helps ensure that divers plan their dives properly, monitor their depth and time, and make informed decisions to maintain safety throughout their diving experiences. Adhering to these limits is vital for the diver's health and safety, supporting the principle that safe diving practices must always be the foremost priority.
