Spirometry

track self-rated physical exertion (scale of 6-20) and the modified Borg Rating of Perceived Dyspnea was used to track self-reported breathlessness (scale of 1-4) For this investigation, an MC-TA-200V Metabolic Cart was used to collect pulmonary spirometry data while the subjects performed their exercise on a Monark 828E cycle ergometer. A Hypoxico HYP123 hypoxic generator was used in conjunction with a Douglas Bag to create an FiO2 of 13.8% and a PO2 of 101 mmHg compared to the fraction of…

Smoking and its effect on chronic obstructive pulmonary disease Elizabeth Thoms BIOL 2458, Brijesh Bridge, 10/11/15 Breathing should not be a difficult process, it is something that we do not even have to think about doing, it happens naturally and this should be the way it always is but unfortunately, for some people, this is not the case. Chronic obstructive pulmonary disease, better known as COPD is a disease of the lungs where air flow is reduced in the airways making it very difficult to…

A low spirometry is consistent with COPD but may not be specific to the disease because it may be caused by other lung disease or by poor performance during testing. Symptoms to look out for include chronic cough, sputum production, difficult labored breathing…

uncertain and given that we have no past chest imaging that Ron can recall, they either represent old changes or are progressive interstitial lung disease. The reassuring thing is that his relatively well-preserved lung function tests with his normal spirometry and only mild decrease in gas transfer factor and, as such, the findings are probably incidental and unlikely to be contributing to much to his shortness of breath on exertion. Ideally, a lung biopsy would help differentiate between old…

Cardiovascular Diseases (CVDs) represents an escalating public health issue, worldwide. Statistics indicate that cardiovascular disease is one of the leading causes of mortality worldwide. It accounts for a near 17.5 million deaths every year.1 Moreover, CVD is responsible for significant and alarming morbidity, disability and loss of work.In 2010, a study indicated that the cost of CVD in the United States of America was around $444 billion. It may also be pertinent to mention that the…

1 Chronic cough 2 Current smoker - 15-20 pack-year history 3 Gastro-oesophageal reflux disease/hiatus hernia 4 Diverticular disease 5 Osteoporosis Thank you for referring Jillian Whiffen, a 72-year-old lady who has previously owned a news agency and worked for a family business. Jillian currently smokes six cigarettes per day and keeps no pets. Regular medications are Nexium, Ostelin, Cardia, Crestor, Prolia infections and she was using Pulmicort a couple of months ago. Around three…

My interest in biology and chemistry stems from the fact it explains a world that’s not visible to the eye, but is a key role to life. This sparked my interest in the intricacy of the human anatomy and physiology which has me curious to the research required. The desire to pursue a career in helping others, but also to explore science at a greater depth. I believe biomedical science will enable me to broaden my perspective and give me a solid foundation of knowledge and skills required for…

When dealing with patients with Cystic Fibrosis it is important to know what education materials are needed for the patients and their families, whether it is in a hospital, a home, or in a specialized program. Some facilities in particular, will have educational materials online so that the patient’s families can print them out and review the material. The education materials will include instructions on how to perform the following: active cycles of breathing techniques, autogenic drainage,…

Asthma is a chronic (lifelong) lung disease that makes it harder to move air in and out of your lungs. With asthma, your airways' lining tends to always be in a hypersensitive state characterized by redness and swelling (inflammation). It's similar to how your skin becomes red, irritated and sensitive after a sunburn. With asthma, the airways in your lungs are often swollen or inflamed. This makes them extra sensitive to things that you are exposed to in the environment every day. When you have…

Thank you very much for referring your wife along for management of her asthma. As you are aware, she was first diagnosed with asthma at about the age of 17 or 18, but does believe that perhaps prior to that, there was some exercise-induced bronchospasm that had been left untreated. Since that time, she has been taking Ventolin only very occasionally and never more regularly than once or twice a week. Her normal triggers have previously been cold air, exercise, viral infections and sulfur.…
