Respiratory Care


The human respiratory system consists of the lungs and tubes associated with the lungs. It is located in the thorax, or chest. The thorax is surrounded by the ribs. The diaphragm forms the base of the thorax.
Contractions of the diaphragm and the intercostal muscles change the size of the thorax and, thus, cause air to move in and out of the lungs. The main job of the respiratory system is to get oxygen into the body and get waste gases out of the body. It is the function of the respiratory system to transport gases to and from the circulatory system. Some common respiratory problems are,

Sinusitis: Sinus infections are caused by infections from a pathogenic microorganism (virus, bacterium, or fungus), which grows within a sinus and causes intermittent blockage of the sinus ostium. Most people do not transmit sinus infections except for rare instances, Sinusitis is inflammation of the air cavities within the passages of the nose. Sinusitis can be caused by infection, but it can also be caused by allergies and chemical or particulate irritation of the sinuses. Sinus infection symptoms include sinus headache, facial tenderness, pressure or pain in the sinuses, fever, cloudy, discoloured drainage, and a feeling of nasal stuffiness, sore throat, and cough. Bacterial infection of the sinuses is suspected when facial pain, pus-like nasal discharge, and other symptoms persist for longer than a week and are not responding to over- the-counter nasal medications. A sinus infection is generally diagnosed based on the patient’s history and physical examination by a health care practitioner. Early treatment of allergic sinusitis may prevent secondary bacterial sinus infections. Bronchial asthma is a disorder that causes the airways of the lungs to swell and narrow, leading to wheezing, shortness of breath, chest tightness, and coughing. Asthma is caused by inflammation in the airways. When an asthma attack occurs, the muscles surrounding the airways become tight and the lining of the air passages swells. This reduces the amount of air that can pass by. In sensitive people, asthma symptoms can be triggered by breathing in allergy-causing substances (called allergens or triggers). Common asthma triggers include: animals (pet hair or dander), dust, changes in weather (most often cold weather), chemicals in the air or in food, Exercise, Mold, Pollen, Respiratory infections, such as the common cold, Strong emotions (stress), tobacco smoke, aspirin, and other non-steroidal anti-inflammatory drugs (NSAIDs) provoke asthma in some patients. Many people with asthma have a personal or family history of allergies, such as hay fever (allergic rhinitis) or eczema. Others have no history of allergies.

Allergic rhinitis and sneezing: Rhinitis refers to inflammation of the nasal passages. This inflammation can cause a variety of annoying symptoms, including sneezing, itching, nasal congestion, runny nose, and post-nasal drip (the sensation that mucus is draining from the sinuses down the back of the throat). Brief episodes of rhinitis are usually caused by viral respiratory tract infections (e.g., the common cold). Chronic rhinitis is usually caused by allergies, but it can also occur from overuse of certain drugs, some medical conditions, and other unidentified factors. For many people, rhinitis is a lifelong condition that waxes and wanes over time. Fortunately, the symptoms of rhinitis can usually be controlled with a combination of environmental measures and homoeopathic medications very effectively.

Bronchitis/cough: “Bronchitis”┬ásimply means an inflammation of the bronchus, the windpipe. This is usually caused by infection (viral, bacterial, fungal, etc.) or allergy, or both. This condition is widely prevalent throughout the world and is a frequent cause of Coughing is the most common symptom. The cough may be either dry (without mucus) or wet (with mucus), depending on the cause and severity. Allergic cough is often dry, while infective cough has a tendency to have mucus production. The symptoms of bronchitis may be listed as follows: cough (with or without mucus), fever, chest pain, difficulty breathing (dyspnea), throat pain, nasal congestion, Body ache, joint pain, and tiredness (usually due to infection) If there is an underlying cause of lowered immunity or a tendency to catch infection, or if there are factors such as smoking and environmental pollution, there may be a tendency to have recurrent bronchitis. Bronchitis seems to be slightly more common in women as compared to men, though the difference is not significant. It is more common among the younger age group as compared to the adult population.
