Shortness of breath (dyspnea) strikes deep at a person’s self-preservation instincts. The fear of suffocation commonly leads to a feeling of panic. The ability to diagnose and treat the condition depends upon past medical history, the ability to gather a good medical history of the acute condition and prompt evaluation of the patient’s physical findings.

How many asthmatics think their asthma is under control? If you are like most Canadians, 91 per cent believe so. Indeed, perception is not a mirror of reality.

From time to time I receive mail from readers asking about various medical conditions. One such letter contained numerous questions about asthma and lung disease that I wish to address in this column.

Take a regular diameter (pencil eraser) size straw and breathe through it while pinching your nose for five minutes. How many would be able to complete this task before gasping for air? Everyone understands the panic that envelops us when we cannot breathe. This universal response is one of our greatest fears. Despite this, an increasing number of people experience and live with the straw reality and are slowly suffocating to death.

Last week’s column reviewed how obstructive sleep apnea is more than just a problem of poor sleep. More than 90 per cent of obstructive sleep apnea sufferers remain undiagnosed and face real health risks.

Aside from the jokes and a partner’s resignation to a lifetime of disrupted sleep, snoring is not an issue that gets much airplay. Snorers, including the “I-don’t-snore” crowd, may have more than just a problem of annoying those within their noise radius.

Most people know the risks of cigarette smoking. They often employ many strategies to quit, often with lukewarm success. An understanding of the addictive nature and the associated habits and triggers of smoking is essential before attempting a smoking cessation program.

Asthmatics can suddenly crash and burn. Last week’s column made note that asthma is an inherently unstable disease. Some patients unknowingly play with fire by ignoring the symptoms. A good web site to determine the risk of asthma in children and adults is found at http://allergy.mcg.edu/home.html.

Asthma management continues to be a problem for some patients. This is borne out by the telephone call from a patient who frequently runs out of their Ventolin puffer. A review of their chart shows repeat monthly or bimonthly renewal requests; a red flag denoting poor asthma control.
