Gasping for the Gold?Playing host to this year's summer Olympic games is one of the world's most polluted cities, a fact that might impact the performances of competitors, especially those with asthma, according to theAmerican Academy of Allergy, Asthma & Immunology(AAAAI). ���Not only will athletes have irritated eyes, but a good portion may have decreased potential to be competitive,��� said Timothy Craig, DO, FAAAAI, and chair of the AAAAI Sports Medicine Committee. ���Exercise can enhance the adverse effects air pollutants have on health. Rigorous exercise combined with pollutants can sometimes stimulate an asthma attack

Oxygen on the Go!by Rick Carter, PhD, MBA; James S. Williams, PhD; and Brian Tiep, MDSmaller, lightweight oxygen devices give patients new freedom���the primary goals are to address the underlying pathophysiology and to correct hypoxemia with supplemental oxygen. As the patient's care progresses from acute intervention, and the long-term need for supplemental oxygen is determined, the next decision focuses on the best oxygen delivery devices and configurations to prescribe. The clinician must address patient needs, costs, mobility, ease of use, access, time in ambulation per day, and other important life-preserving/enhancing considerations.

Transtracheal Oxygen DeliveryTranstracheal catheters were first introduced by Heimlich9,10and have been further improved and refined.11-13Transtracheal catheters deliver oxygen via a surgically placed hole in the neck. Hence, the decision to deliver oxygen in this manner requires several considerations on the part of the patient and clinician. First, minor surgery is required to place the catheter, and thus, a very small potential for complications exists. Second, the catheter requires some ongoing inspection and care on the part of the patient. The catheter should be checked daily for potential failure, breakage, and restricted flow. If these are suspected, the catheter can be replaced. Mucus can plug the catheter, and the patient must be willing and able to clean and troubleshoot the catheter when required. These concerns aside, transtracheal catheters offer patients a high-quality delivery system that is hidden from sight and provides significant oxygen savings as compared to standard nasal cannula. Additionally, transtracheal catheters can be coupled to pulsed-flow devices to further improve their efficacy.14Because transtracheal oxygen delivery bypasses the upper airway, questions concerning humidification have been raised, given the possibility of mucous plugging or mucous ball formation on the end of the catheter. Studies have demonstrated that at flows of less than 4 LPM via nasal cannula, humidification is generally not necessary.15However, for transtracheal delivery especially at high flow, humidification is recommended.Read more about >

Research May Point to Genetic Susceptibility to COPDA subset of genes might indicate a smoker's risk for COPD, according to new research out of Cornell University in New York."Despite the overwhelming evidence of cigarette smoking as the major risk factor for the development of COPD, the majority of long-term smokers remain healthy, strongly suggesting that genetic factors modify disease susceptibility to this environmental stress," the authors note.
