For new divers, mastering the art of equalization can be a daunting task. Equalization is the process of equalizing the pressure inside your ears, sinuses & mask to the surrounding water pressure. Failure to equalize properly can result in discomfort and, in some cases, serious injury. In this blog post, we'll provide you with essential tips to help new divers master the art of scuba equalization and enjoy their underwater adventures to the fullest.
Start with Proper Training
Before you embark on your scuba diving journey, it's crucial to undergo proper training with a certified instructor. A certified scuba instructor will teach you the essential skills and techniques, including equalization, to ensure your safety and enjoyment underwater. Invest in a reputable scuba diving course to build a strong foundation for your diving adventures.
Understand the Basics of Equalization
Equalization is balancing the pressure inside your ears and sinuses to the increasing water pressure as you descend underwater. The mechanics are simple. Your regulator delivers air to you at the ambient water pressure. Your sinuses and mask have air pressure that is LESS than the ambient water pressure, so they get "squeezed", By equalizing your airspaces, you are putting ambient pressure air into those spaces to prevent the squeeze. The two most common methods of sinus equalization are the Valsalva maneuver and the Frenzel maneuver.
- Valsalva Maneuver: Pinch your nose shut and gently blow against the closed nostrils. This action forces air into the Eustachian tubes, equalizing pressure. NEVER FORCE this technique as it can lead to middle ear injuries. If you are not successful, we always recommend you ascend slightly and try again,
- Frenzel Maneuver: This advanced technique involves closing the throat and using the tongue and throat muscles to control airflow. It's more efficient and recommended for scuba divers but takes some practice to execute successfully. The more you dive the easier this technique becomes.
Most of the tine we don't even consider equalizing your mask. However it is an airspace that needs consideration, The easiest and most common way to equalize your mask on descent is simply exhaling through your nose. If for some reason that does NOT work (perhaps you are congested on one side) you can always break the seal of your mask, let a little water in which will automatically equalize that airspace.
Professional equalization tips
Our instructors have trained hundreds of students and we've picked up a few tricks along the way:
- Snot rockets (closing one nostril and blowing out the other) does wonders to loosen sinuses.
- Wiggling your jaw and even rubbing underneath your ears can help equalization.
- Equalize BEFORE you feel any discomfort or pain.
- Cold water diving makes equalization more difficult so try to minimize up/down movement.
- Staying well hydrated makes equalization easier.
- Do NOT take decongestants before diving. If they wear off underwater you are setting yourself up for a reverse block.
- Don't ever force it. If you can't equalize, there is nothing down there worth a barotrauma.
Equalize Early and Often
One of the most important equalization tips for new divers is to start equalizing early in your descent and continue to equalize frequently. Don't wait until you feel discomfort or pain in your ears. Make it a habit to equalize every few feet as you descend to maintain equal pressure. Not only does this reinforce the habit, it "exercises" the muscles needed to make future equalization even easier. A fun fact is the deeper you go, the pressure "gradient" or "differential" becomes less, so you do not need to equalize as often.
Descending too quickly can make equalization more challenging. Take your time when descending and avoid rapid descents when working through any equalization issues. A slow, controlled descent allows your body to adjust to the increasing pressure gradually.
Equalizing While Ascending
Equalization when ascending is usually not required. As ascents should always be controlled and at a rate of no faster than 60' per minute, the higher pressure air should naturally escape. However, if you feel pain in your sinuses while ascending, STOP. There is a condition called a "reverse block" which means higher pressure air is trapped in an airspace and is extremely painful. If you ever find yourself with a reverse block, stop your ascent (provided you have ample gas) and try wiggling your jaw, equalizing and generally try to work the air out of your sinuses by using the above methods.
Tension and anxiety can make equalization more difficult. Relaxation is key to successful equalization. Focus on your breathing and remain calm throughout your dive. Tense muscles can constrict the Eustachian tubes, making it harder to equalize.
Seek Help If You Encounter Problems
If you experience equalization issues or discomfort during a dive, it's essential to signal your dive buddy or instructor. Ignoring problems can lead to more serious issues like barotrauma. Safety should always be your top priority. If you know you have challenges equalizing, be sure to use a line or visual reference on descents to assist in maintaining your depth while equalizing.
Equalization is a fundamental skill for scuba divers, and mastering it is crucial for a safe and enjoyable diving experience. With proper training, understanding of the techniques, and regular practice, even new divers can become proficient in equalization. Remember to equalize early and often, stay relaxed, and always prioritize safety. By following these essential tips, you'll be well on your way to exploring the underwater world with confidence and ease. Happy diving!
