allergy tests are often used to diagnose asthma (WebMD‚ 2014). Spirometry and the methacholine challenge are two types of lung functioning tests. “Spirometry is a simple breathing test that measures how much and how fast you can blow air out of your lungs. It is often used to determine the amount of airway obstruction you have.” (WebMD‚ para. 4). “The methacholine challenge test may be performed if your symptoms and screening spirometry do not clearly or convincingly establish a diagnosis of asthma

volume of air which they can expire after a full inspiration. Age‚ sex‚ height‚ weight‚ the size and flexibility of the chest‚ muscular strength and physical training are factors which may singly or jointly affect the vital capacity (West 1920). Spirometry measures airflow from fully inflated lungs over time in liters (Petty 2002). The purpose of this study was to determine if vital capacity is affected by any of the following factors: gender‚ athlete or non-athlete‚ and position of measurement.

COPD which is Chronic Obstructive Pulmonary Disease is known as a condition that progressively makes it harder to breathe because the airflow into and out of the lungs is reduced. This usually occurs because the airways and air sacs lose their elastic quality‚ the walls between the air sacs are destroyed‚ the walls of the airways become swollen‚ or if the airways are clogged because they made more mucus than usual. Three main conditions of this disease are emphysema‚ chronic obstructive bronchitis

The Asthma Epidemic: Diagnosis‚ Treatments and Management‚ all prospects towards a better future Asthma is a multifactorial chronic disorder that has displayed a significant increase in prevalence and incidence worldwide over the past two decades‚ particularly in developed countries (Hazeldine‚ 2013). The World Health Organization estimates that 235 million people currently suffer from this common respiratory condition. Despite this growth‚ over that same period of time‚ global asthma mortality

and pursed-lip breathing (see Picturing a barrel-shaped chest). The healthcare provider will confirm a diagnosis of COPD with spirometry. Considered the gold standard for diagnosing and monitoring disease progression‚ spirometry is the most accurate and objective means to measure airflow limitation. It also helps to differentiate COPD from other pulmonary diseases. Spirometry includes measurement of forced vital capacity (FVC)‚ the maximal amount of air that can be rapidly and forcefully exhaled from

Asthma is a chronic inflammatory disease of the airway. The narrowing of air occurs due to the inflammation and excessive mucous secretion. Asthma is know to be the commonest diseases in childhood and in young adulthood. Mr Saunders suffering from asthma encounters exacerbation‚ which commonly means asthma attack or acute asthma leading to shortness of breath‚ wheezing and many other symptoms. Exacerbation refers to decline in expiratory airflow‚ which can bring mild to life threatening conditions

Psychology in Respiratory Therapy When I decided I wanted to be a respiratory therapist‚ I never imagined that I would be dealing with any psychological aspects. As I have learned more about the respiratory system and the patients that I will treat‚ I can see that I will deal with some psychological factors quite often. In respiratory therapy there are psychological factors that can affect a person’s ability to breath and their quality of breathing. A range of emotional factors including

The patient was apparently well until about 6 months prior to consult‚ when he began to experience dyspnea when walking more than 20 ft.‚ associated with chronic productive cough. No consult was done‚ no medications taken‚ and no weight loss reported. Three days prior to consult‚ the patient’s
