What should be done when oxygen is restored after temporary loss during treatment?

When oxygen is restored after a temporary loss during treatment, resuming treatment at the point of interruption is the appropriate action. This is because effective treatment protocols for conditions such as decompression sickness or carbon monoxide poisoning involve closely monitored increments of oxygen exposure. Resuming from where treatment was halted ensures that the patient receives continuous therapy without unnecessary disruption, which is critical for the treatment to be effective and to minimize potential complications.

Going back to the point of interruption allows the patient to benefit from the therapeutic effects of oxygen as soon as possible, as any delay might result in worsened symptoms or inadequate treatment outcomes. Each treatment session is designed to progress toward specific physiological responses, and interjecting unnecessary pauses could hinder recovery.

In contrast, stopping all procedures or initiating a new dive cycle would likely cause delays in effective treatment. Completing an extra oxygen period is unnecessary and could lead to excessive oxygen exposure, which is also not aligned with standard protocols for treatment. Therefore, resuming treatment at the point of interruption is the most scientifically sound approach in this scenario.
