Prophylactic Nasal Irrigation to Facilitate Middle Ear Pressure Equalization in Experienced Scuba Divers
David F Colvard, MD Raleigh, NC
Objective: Middle ear squeeze caused by difficulty equalizing the pressure in ears during descent and ascent is among the most common problems in recreational scuba divers. Many divers use pre-dive oral or topical decongestants to help equalize pressure in their middle ears and sinuses. This study aimed to determine the efficacy and safety of the alternative of nasal irrigation prophylaxis among experienced divers to facilitate middle ear pressure equalization and reduce the use of decongestant medications.
Methods: Web-based "Before" and "After" questionnaires were taken by experienced scuba divers who had previously reported having difficulty equalizing their middle ears or having used oral or topical decongestants and who volunteered to use free samples of NeilMed's SINUS RINSETM irrigation system before diving. (Surveys were taken between Nov 2005 and Sep 2006.)
Results: One hundred male and female experienced divers completed both "Before" and "After" web-based questionnaires. Forty-four (44.0%) reported less nasal congestion after using SINUS RINSETM and ten (10.0%) reported more nasal congestion. Sixty-nine (69.0%) reported less frequent difficulty in clearing or equalizing their ears and five (5.0%) reported more frequent difficulty. Forty-one of 68 divers (60.3%) for whom use of oral decongestants were applicable reported decreased or discontinued use. Twenty-one of 38 divers (55.3%) for whom use of decongestant sprays or drops were applicable reported decreased or discontinued use. None reported increased use of decongestants in any form. Seventy-two (72.0%) would recommend the SINUS RINSETM system to other divers and three would not.
Conclusions: Experienced scuba divers continue to dive despite the medical relative risk of nasal congestion and difficulty clearing or equalizing their middle ears. Nasal irrigation can effectively and safely reduce nasal congestion and decrease the frequency and difficulty in clearing or equalizing their middle ears in many divers. Additionally, nasal irrigation can decrease the use of decongestants, both oral and spray or drops, and reduce the risk of rebound congestion and reverse middle ear squeeze during or after a dive when the decongestants might have worn off. A nasal irrigation system like NeilMed's SINUS RINSETM appears to be an economical, convenient, safe, and effective prophylactic alternative to decongestant medications for many recreational divers who choose to dive despite the medical relative risk of nasal congestion and difficulty clearing or equalizing their middle ears.

Some amount of mucus production from the nasal and sinus lining is normal. Allergies and infections will cause excessive mucus production. This will create nasal and sinus symptoms such as runny and stuffy nose and post nasal drip. When the nasal rinse is performed, you wash away mucus, allergy causing particles and irritants such as pollens, dust particles, pollutants and bacteria, thus reducing the inflammation of the mucus membrane. Normal mucosa will fight infections and allergies better and symptoms will be reducedand allow the Eustachian tube to function more normally.

The above study results were presented on September 27, 2007 at SAUHMA Conference - "Refresher Course in Underwater Medicine 2007" in Johannesburg, South Africa.

Demonstration video of SinusRinse
Who uses NeilMed's SINUS RINSETM irrigation system before diving?
Women's freediving record holder Mandy-Rae Cruickshank and many international competitive freedivers. While scuba divers have the luxury of taking their time to equalize the pressure in their middle ears, freedivers have to be able to equalize easily and instantly or they can't dive. Sinus and nasal congestion are a common problem faced by these athletes as they travel the world for training and competition. NeilMed's SINUS RINSETM irrigation system can dramatically shorten the time required for them to clear their heads for the next event.
April 30, 2008 - Mandy-Rae and her coach Kirk and others will be on
Oprah for a
full hour on Freediving.
Nasal saline irrigation
What is nasal saline irrigation?
Nasal irrigation is used when greater volumes of saline are needed, for example, when large mucus crusts build up or nasal/sinus polyps block mucus clearance.
To irrigate your nasal passages, a bulb syringe (used to clear the nasal passages of babies) can be used.
To make your own nasal irrigation solution, mix:
¼ tsp. of kosher or pickling salt
¼ tsp. baking soda
8 oz. of warm tap water
(1 tsp. of salt, 1 tsp baking soda per 32 ounces of water)
Sinus Rinse SystemPremixed salt packetsSince tap water may have some bacterial impurities, you may choose to use distilled water instead. Boil the distilled water and store in a refrigerator until you add the salt and baking soda.
Or, you can purchase the "Sinus Rinse" system available at most pharmacies, which comes with single use salt packets. The Sinus Rinse system may be easier and more comfortable to use than a bulb syringe.
How do I do saline irrigation?
Use 8-16 ounces of solution in each nasal cavity 1-2 times daily, or as often as is prescribed by your health care provider.
• Lower your head over a sink and turn your head so that your left nostril is down.
• Pour solution from the container into your right nostril.
• Water will drain from your left nostril into the sink.
• Gently blow your nose.
• Repeat the same process for other nostril.
Breathing through your nose during irrigation will prevent a mess and minimize the amount that enters the throat. You should use only enough pressure to move the solution to the back of your nose so it comes out though your mouth or nose. This should not cause major discomfort once you are used to it.
Prepare fresh solution each day and clean the Sinus Rinse bottle after each use.

"Beer While Diving? There have been recent assertions in scuba magazines, chat rooms and scuba forums that it’s OK to drink beer between dives during a surface interval. Some divers insist on drinking beer before, during and after their dives. Is there any danger in drinking alcoholic beverages and diving? The short answer is that by drinking alcohol before and during diving trips a diver severely endangers not only himself but his buddy!" (reprinted from April 2008 Ten Foot Stop)

Air Travel
Effective January 1, 2008, the Department of Transportation (DOT) through the
Pipeline and Hazardous Materials Safety Administration (PHMSA) will no longer
allow loose lithium batteries in checked baggage.
Learn more at
http://safetravel.dot.gov/.
Lithium-ion
batteries, often found in laptop computers, differ from primary lithium
batteries, which are often used in cameras. Some newer AA-size batteries are
also primary lithium.
While there is no explosion hazard associated with either kind of battery, the Federal Aviation Administration has studied fire hazards associated with both primary and lithium-ion cells, and their extensive research is publicly available. As a result of this research, the FAA no longer allows large, palletized shipments of these batteries to be transported as cargo on passenger aircraft.
The research also shows that an explosion will not result from shorting or damaging either lithium-ion or primary lithium batteries. Both are, however, extremely flammable. Primary lithium batteries cannot be extinguished with firefighting agents normally carried on aircraft, whereas lithium-ion batteries are easily extinguished by most common extinguishing agents, including those carried on board commercial aircraft.
TSA has and will continue to work closely with the FAA on potential aviation safety and security issues, and TSA security officers are thoroughly and continually trained to find explosive threats. TSA does not have plans to change security regulations for electronic devices powered by lithium batteries.

Survey of Skin and Scuba Divers in the December 2004 Indonesian Tsunami
This is a world-wide Internet survey of skin and scuba
divers who were in or on the water in the Indonesian tsunami on 26 December 2004
. There has been little or no published information regarding the effects of
natural disasters on divers. Drs. Tom Skalko and Carmen Russoniello of East
Carolina University and I are studying what that experience was like for divers
and how it has affected their lives since then. We need divers who were in or on
the water to help us by completing the survey.
Some of the survey
questions may be upsetting, even months after the tsunami. It will take about 10
- 20 minutes to complete. The survey will automatically skip past questions that
do not apply based upon answers to earlier questions. Results will be compiled
and completed as a group only. No individual identifying information will be
released to anyone. The risks of participating in this survey are considered
minimal.
If you were in or on the water in the tsunami or know of any skin or scuba divers who were in or on the water in the tsunami, then please ask them to go directly to the survey URL to complete the survey:

| ETYMOLOGY: | Middle English diven, from Old English d fan,
to sink; see dheub- in
Appendix I. |
| USAGE NOTE: | Either dove or dived is acceptable as the past tense of dive. Usage preferences show regional distribution, although both forms are heard throughout the United States. According to the Dictionary of American Regional English, in the North, dove is more prevalent; in the South Midland, dived. Dived is actually the earlier form, and the emergence of dove may appear anomalous in light of the general tendencies of change in English verb forms. Old English had two classes of verbs: strong verbs, whose past tense was indicated by a change in their vowel (a process that survives in such present-day English verbs as drive/drove or fling/flung); and weak verbs, whose past was formed with a suffix related to Šed in Modern English (as in present-day English live/lived and move/moved). Since the Old English period, many verbs have changed from the strong pattern to the weak one; for example, the past tense of step, formerly stop, became stepped. Over the years, in fact, the weak pattern has become so prevalent that we use the term regular to refer to verbs that form their past tense by suffixation of Šed. However, there have occasionally been changes in the other direction: the past tense of wear, now wore, was once werede, and that of spit, now spat, was once spitede. The development of dove is an additional example of the small group of verbs that have swum against the historical tide. |

Beginning with the June 2000 Bonaire Dive Festival, David F. Colvard, M.D., a private psychiatrist and clinical investigator in Raleigh NC, a divemaster, and a Sand Dollar Condominium Resort home-owner, has been conducting online surveys of thousands of divers around the world. His first study on diver panic in over 12,000 divers was sponsored by Rodale's Scuba Diving magazine and was supported by Drew Richardson at PADI. Dr. Colvard presented a poster and abstract at the 35th Undersea and Hyperbaric Medical Society Scientific Meeting in San Diego, CA, in June 2002. He and his wife Dr. Lynn Colvard wrote A Study of Panic in Recreational Divers for The Undersea Journal (Professional Journal of Professional Association of Diving Instructors), which was the feature article in the winter quarter 2003 issue. He has continued to conduct follow up online surveys of those divers and others on a variety of topics, including PTSD in the divers who survived the December 2004 Southeast Asian tsunami. Dr. Colvard recently completed a study of middle ear pressure equalization using SINUS RINSE™ for NeilMed Pharmaceuticals and represented the company at DEMA Show in Orlando. He has made several presentations to the staff of Divers Alert Network at Duke University Medical Center and is frequently quoted in Scuba Diving magazine and elsewhere. He hosts the website http://www.divepsych.com/ which provides evidence-based information for divers on psychological and stress factors in scuba divers. For fun David enters underwater photography competitions.
