Over-the-counter nasal sprays or decongestants can also help air travelers to shrink the membranes and help the ears pop more easily. If you have allergies, take your medications at the beginning of your flight. You and your children should avoid sleeping during descent because swallowing may not occur often enough to keep up with changes in air pressure. Plus, babies cannot intentionally pop their ears, but sucking on a bottle or pacifier can help. You’ll know if it worked when you hear a pop, and your ears feel less plugged.īabies and children are especially vulnerable to ear blockage because their eustachian tubes are narrower than in adults. You can also try pinching your nose, taking a mouthful of air, blowing gently (not forcefully) against your pinched nose, then swallowing. Yawning, chewing gum, or sucking on hard candy can help, especially just before take-off and during descent. The simplest way to help clear your ears-particularly when flying-is to swallow. Also, any situation in which rapid altitude or pressure changes occur, such as air travel, riding in an elevator, diving to the bottom of a swimming pool, or scuba diving, can affect proper function of the eustachian tube. A stuffy nose leads to stuffy ears because the swollen membranes in the nose can extend into the eustachian tube and block it.

The most common cause of eustachian tube blockage is the common cold, but sinus infections and nasal allergies are also usual suspects. The eustachian tube is a membrane-lined tube about the width of a pencil lead that connects the back of the nose with the middle ear and helps maintain balanced air pressure on both sides of the eardrum. The common cold, sinus infections, and nasal allergies can also interfere because swollen membranes in the nose can extend into the eustachian tube and block it (see “What Causes Barotrauma?” below). This stretches the eardrum and causes pain and occasionally fluid. When the eustachian tube in your middle ear is blocked due to altitude or pressure changes (sometimes called barotrauma), air cannot be equalized, and a vacuum occurs. While they are usually minor annoyances, sometimes they can cause significant symptoms. It is always important to stay well hydrated before every dive, especially in deco diving.Ear problems are one of the most common medical complaints of airplane travelers and divers. Decrease your bottom time by a few minutes.

Keep the same times as for the air profile, even if you switch to EAN.

  • Add enriched air Nitrox (EAN) as a decompression gas starting on the deco stops to add oxygen to your decompression phase and speed up nitrogen elimination.
  • Ascent rates are one of the main keys to safe decompression.
  • Add time to the shallower deco stops (e.g., another two minutes at 20 and 30 feet), and follow the ascent rates that your instructor proposed.
  • If you are concerned about an increased risk of decompression sickness (DCS), you can consider options to make the dive more conservative, such as the following: I assume your instructor chose these times based on the dive tables of your training organisation or a commercially available dive planner. The dive profile is decompression (deco) diving, which requires decompression stops, and all these tables were developed for square profiles. The profile you describe is within the limits of currently available dive tables and is slightly more conservative than the U.S. Is this a safe profile, or should it be more conservative? Is that safe with regards to nitrogen buildup? I have an upcoming dive with the following profile:Įvery time above 130 feet includes a one-minute ascent. Our instructor wants us to dive an extended time at depth. I am currently taking a master scuba diver course.
