What should you do if there is a delay of less than 1 minute to the first deco stop?

In the event of a delay of less than 1 minute before reaching the first decompression stop, it is generally advised to disregard the delay. The rationale behind this recommendation is based on the understanding of how decompression theory works and the body's tolerance to brief delays. A minor delay, such as one that lasts under a minute, is typically not substantial enough to negatively affect the safety of the diver in terms of decompression sickness or injury.

The importance of adhering to proper decompression schedules cannot be understated, but minor variations that occur during ascent can often be managed without significant concern, especially at the early stages of decompression. Safety protocols prioritize stability and well-being, so in cases where delays are minimal, divers are trained to maintain their ascent pace and focus on the upcoming stops.

While it is beneficial to note any delays and maintain awareness of ascent timing, particularly for further dives, the immediate response to a brief interruption does not necessitate any corrective action such as increasing ascent speed or reporting to supervision. These actions are typically reserved for more significant delays that could impede a safe ascent.
