Diving with Asthma

Written by Sheldon Hey


Continued from page 1

In this day and age where people do not want to take responsibility for their own actions,repparttar most prudent thing for a dive physician to do when an asthmatic walks into his surgery is to say "Bog off, you're unfit". This happens frequently, and who can blamerepparttar 114342 doctors? However, while it might be defensive medicine, it is not necessarily good medicine. Indeed, such subjective pronouncements often motivaterepparttar 114343 candidate to go to another doctor and lie about having asthma. There is now an alternative informed consent basis of assessment. Fundamentally, this means clearly and comprehensively explainingrepparttar 114344 risks of diving torepparttar 114345 candidate, and letting him make an informed choice about whether to proceed. However, there are some important provisos. Inrepparttar 114346 context of asthma, most dive physicians would agree thatrepparttar 114347 more activerepparttar 114348 asthma,repparttar 114349 greaterrepparttar 114350 risk in diving. Those candidates who suffer serious attacks, wheeze relatively often or who use reliever medications regularly, cannot be considered for diving, even on an informed consent basis, because rightly or wrongly,repparttar 114351 risks are perceived to be too high.

Onrepparttar 114352 other hand, previous asthmatics and milder cases may be subject to little extra risk, and it is reasonable to let them, as intelligent adults, make up their own minds onrepparttar 114353 matter. Every day of our lives we make decisions that inherently involve weighing risk against benefit. We choose to get on planes, we choose to play rugby, we choose to ride bicycles on busy roads, all because we deciderepparttar 114354 benefit outweighsrepparttar 114355 risk. There is no reason diving should be any different in this regard, although dive candidates are much less well-informed about its inherent risks than they are about these other intuitively obvious risk situations. It isrepparttar 114356 dive physician's role in this setting to sufficiently educate candidates so they can make an informed choice.

A sensible approach torepparttar 114357 asthmatic dive candidate is to first take a detailed history of his problem. The obvious active asthmatics are told they cannot dive, andrepparttar 114358 reasons are clearly explained. Asthmatics who have not experienced symptoms of asthma or have not used medication for years are usually able to dive without any special investigations.

The most problematic are mild asthmatics i.e. those candidates who wheeze once or twice a year when they have colds; or who wheeze a little inrepparttar 114359 spring when certain pollens are around, etc. With these candidates, a long discussion aboutrepparttar 114360 potential risks in diving implied by their asthmatic history, is usually followed with tests to check that neither exercise norrepparttar 114361 breathing of nebulised salt water (atrepparttar 114362 same concentration as sea water) provoke airway narrowing. If these tests are negative and patients exhibit a clear understanding ofrepparttar 114363 issues and wish to proceed, then we should be happy for them to dive. Unfortunately, to conduct and document this process properly is a time consuming and expensive exercise, but at least it's better than being told to "clear off" without so much as an explanation.

Currently, Hyaluronic acid injections are most commonly used aroundrepparttar mouth and on forehead wrinkles and smile lines and to enlarge, moisturize and “plump” lips. The entire injection process takes less than an hour, and requires repeat treatments every four months to a year. Hyaluronic acid treatments are more expensive than those using collagen (a syringe of Restylane or another Hyaluronic acid product might cost up to $500 as compared to around $373 for collagen) but HA injections last longer because they helprepparttar 114341 skin retain natural moisture. When injected,repparttar 114342 filler plumps uprepparttar 114343 skin by allowing it to attract and hold water. Side effects are much less likely with Hyaluronic acid than with collagen contributing to its attractiveness as an alternative treatment.

The possibilities seem endless for uses of Hyaluronic acid. In Japan, Daikin Industries is even offering an air conditioner that emits Hyaluronic acid fromrepparttar 114344 filter to moisturize skin. There are sure to be even more innovations and future ways to take advantage of Hyaluronic acid’s many health and beauty benefits.
