如果你对人体生理有基本了解,你就知道我们的身体里有些空腔。当我们身体所处的压力发生变化的时候,比如我们进行水肺或者自由潜水的时候,这些空腔将受到压力的影响。尤其是我们的面部和耳部的空腔,如果在潜水的时候你不对这些空腔中充入额外的气体,你可能在这些部位受到挤压伤。目前在进行深潜时,最为高效和安全的耳压平衡技术,便是Mouthfill。

课程简介:

在这个两天的课程中,你将学习如何使用Mouthfill技术进行深潜。这个课程适合那些在心理和身体上已经准备好进行深潜,但是缺乏必要的耳压平衡技术和练习的人。

在这两天的课程中:你将学习以下技能:

  • 吐气下潜
  • Mouthfill和吐气下潜的结合练习

在这个课程中,你将学习以下理论知识:

  • 常见耳压平衡技术的机制
  • Mouthfill背后的机制以及如何完成有效的Mouthfill
  • 初学者常见的问题以及如何去克服

如果你已经有一定的深潜经验以及Mouthfill的练习,但是出现一些问题,比如漏气,空气控制不好,腹部紧张等等,这个课程再适合你不过了。

MOUTHFILL BANNER 6

COURSE SCHEDULE

VASALVA TECHNIQUE – Antonio Valsalva recorded middle ear pressurization in the 1700s. This simple equalization method is named in his honor. To use it, pinch your nose, close your mouth, and blow air from your lungs into your head space to force air into your middle ear. This technique works to depths of up to 30 meters; at greater depths, you will not have enough air in your lungs to use it. You will practice Vasalva and built a better understanding of this technique’s limit.

FRENZEL TECHNIQUE – Named after a Luftwaffe commander who developed this technique for World War II bomber pilots. It is accomplished by closing off the vocal cords, pinching your nostrils, and attempting to make a “guh” or “k” sound. This will elevate the back of your tongue and lift the Adam’s Apple, which in turn pushes air up into your middle ear. The Frenzel Maneuver is effective at depths of up to 40-50 meters but the risk of lung squeezes is pretty high. After doing 6-10 equalizations your mouth will be empty and you will need to reverse pack to bring some air back up. Competitive Freedivers don’t use Frenzel since Mouthfill equalization has been discovered.

TOYNBEE TECHNIQUE – In the Toynbee Manuever, the muscles at the back of the throat pull the Eustachian tubes open. To accomplish this, pinch your nostrils and swallow. You will hear a clicking or crackling noise. Like the Frenzel maneuver, the Toynbee maneuver works at depths beyond 30 meters and can be repeated.

VTO TECHIQNUE – Also known as the BTV maneuver, the VTO maneuver involves “Voluntary Tubal Opening” (Beance Tubaire Volontaire in French). It is less reliable than other methods; in fact only about 30% of those who try it are able to do it. In this equalization method, the soft palate muscles are contracted while muscles in the upper throat are used to pull the Eustachian tubes open. Its mechanics are somewhat like yawning with one’s mouth closed.

WET TECHNIQUE – A maneuver in which water is allowed to flood the sinuses, the Wet Equalization Maneuver is chiefly used by professional freedivers. It is challenging as there is an increased risk of drowning, and it takes correct training and practice to accomplish it. Do not try this method without appropriate instruction.

MOUTHFILL并不是一种独立的耳压平衡技巧,它是一种通过在口腔储存空气来辅助你的耳压平衡超过RV失效深度的技术。而失效深度就是你的肺部已经被压缩到不能在压缩(压缩到残气量体积),你无法再使用肺部的空气进行的耳压平衡的深度。而Mouthfill的原理就是在你达到RV深度前,将肺部的空气存到嘴里,然后利用口腔里的这些空气进行耳压平衡,而在Mouthfill之后,你就不再使用肺部的空气,你的会厌将全程关闭。这样也能避免在深处从肺部抽取空气造成的肺部挤压伤风险。

在这个课程中,你将知道各种Mouthfill技术的变形,并找到最适合你自己的一种。

During this course, equalization techniques may be combined and personalized, the important thing is to develop the ability to equalize comfortably and to know what will work best for you during freediving. If you scuba dive or freediver, you’ll find that you can use these same methods with reliability, increasing your safety and comfort throughout each and every dive.
