At the end of the dive we ascended and I experienced a reverse block in my right ear. I descended again until it was relieved and then very slowly started ascending again. I was not able to clear it for about 10 minutes. Several times I had to descend and then try to ascend again. Even when I managed to clear it such that I could surface without severe pain, my right ear was still very sore. The next day, I got an appointment with my primary care physician in the afternoon. He sent me to an ENT. The ENT said that the eardrum and Eustachian tube were fine. They performed a pressure test on both ears, as well as a hearing test. Everything appeared to be fine and my hearing was very good in both ears.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Comentario<\/h2>\n\n\n\n<p>A reverse block can happen even when everything else went well in a dive and this diver followed the correct procedure by re-descending to take the pressure off. By re-descending, then slowly trying to ascend in small steps, taking the time to let the trapped gas work its way out, this diver avoided a burst ear drum. This is another example where excellent buoyancy control can make the difference between avoiding an ear injury or suffering one. Remember, the correct hand signals for this are \u201cSomething is wrong\u201d followed by pointing at the problem ear.<\/p>\n\n\n\n<p class=\"has-text-align-right\">Peter Buzzacott, MPH, Ph.D.<\/p>","protected":false},"excerpt":{"rendered":"<p>A reverse block can happen even when everything else went well in a dive and this diver followed the correct procedure by re-descending to take the pressure off.<\/p>","protected":false},"featured_media":0,"template":"","dan_diving_incident_keyword":[],"class_list":["post-1574","dan_diving_incidents","type-dan_diving_incidents","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.0 (Yoast SEO v27.3) -
