What outcome arises during hyperventilation in diving seals relating to gas exchange?

💡 Explanation

When diving seals hyperventilate, increased oxygen uptake reduces carbon dioxide, causing blood pH to rise which reduces hemoglobins oxygen affinity because of the Bohr effect, increasing inert nitrogen uptake into tissues. Therefore a higher susceptibility to decompression sickness arises, rather than prolonged diving duration or enhanced narcosis, which require lower nitrogen or different physiological optimization.
