Can I get Ear Barotrauma from the SCORKL?Updated a year ago

An ear barotrauma occurs when a diver does not properly equalise the pressure in their ears with the surrounding water pressure. Common causes of an ear barotrauma are ineffective equalization techniques, congestion, exceedingly forceful equalizations, or skipped equalizations. 

                                                

Ear barotrauma can occur if the SCORKL is used improperly. To minimise the risk of ear barotrauma, equalise your ears before you feel pain or discomfort. Equalise your ears first on the surface and then constantly (every metres (few feet)) while descending by blowing gently against pinched nostrils.

 

If the pressure difference between the middle and outer ear is greater than about 140mbar (2 psi) a diver’s eardrum will be distorted to the point that they are likely to feel pain and discomfort. This pressure difference can occur by descending as little as 1-2 metres (3-6 feet) without equalizing. 

                   

If the pressure difference between the outer and middle ear is 350mbar (5 psi) or greater, an eardrum rupture is likely. This pressure difference can occur by descending as little as 3 metres (11 feet) without equalizing.
