If descent continues with an ear block, which two issues may arise?

In the scenario described, continuing descent with an ear block primarily leads to pain and eardrum rupture due to the inability to equalize pressure in the middle ear. When an ear block occurs, the pressure inside the ear becomes unequal compared to the outside environment. As a descent continues, this pressure differential can cause significant discomfort or pain as the eardrum is pushed inward. If the pressure imbalance persists, the eardrum may eventually rupture, leading to potential hearing loss and further complications.

This makes identifying pain and the risk of eardrum rupture as the primary issues arising from an ear block during descent clearly significant. Understanding the physiological mechanisms behind ear barotrauma helps emphasize the importance of proper equalization techniques while descending to avoid these severe outcomes.
