The Valsalva Maneuver has many applications and benefits when used correctly. When misused due to a prolonged or forceful application it can have several drawbacks also.
PADI always list the issue they consider primary to divers being the rupture of The Round Window but there can be more adverse effects.
If you ever see a diver attempting forceful Valsalva address the issue and help them work on their equilisation technique or underlying issues that may be causing them to feel they need to forcefully equalise.

Another question which you ca reference the constants listed at the top of every PADI physics exam. It states that every metre sea water the pressure increase is 0.1 ATM.
So the first part of the equation should be depth (35) multiplied by pressure (0.1). The answer should be in absolute pressure so we need to add the additional 1ATM that we start at from the surface. 35 x 0.1 + 1 =

Bethany has just completed her 50th and 51st logged dive with Divemaster, Min. Min sees during the check-in process that Bethany is already a PADI Advanced Open Water Diver, PADI Rescue Diver and has 5 PADI Specialty certifications – Wreck Diver, Underwater Navigator, Peak Performance Buoyancy, Deep Diver and Enriched Air Nitrox.
Min congratulates her after their first dive together and informs her she can now apply for the PADI Master Scuba Diver Rating which Bethany is very happy to hear.
Upon arriving back at the dive centre Min asks one of the Instructors, Cate to assist Bethany with the Master Scuba Diver application. To both of their disappointment, Cate informs them that they are mistaken and Bethany will have to complete an additional PADI Specialty certification with an instructor as they must verify ‘mastery’ for the Master Scuba Diver certification on the final open water training dive.
Is Cate correct?
"The PADI Master Scuba Diver rating isn’t a continuing education program but rather a recognition level based on training and experience; both of which Bethany has. This means that no additional dives are required for the certification and Min is correct in this instance.
All Cate has to do is verify the training: PADI Advanced Open Water Diver, PADI Rescue Diver and has 5 PADI Specialty certifications, and experience: 50 logged dives, and complete the online application for Bethany’s Master Scuba Diver rating."
