B What is a cough reflex?
Lung cancer Lung infections Doctors can perform a variety of tests to diagnose patients with chronic coughs. The tests are accurate and successful, but aside from a simple chest x-ray, testing is usually not necessary.
That's because people can often figure things out for themselves. But before you attempt to diagnose and treat yourself, review the red flags that call for prompt medical attention instead of a do-it-yourself approach below. If you're like most people with a lingering cough, consider these major causes: Postnasal drip also called the upper airway cough syndrome.
The human nose is more than the organ of smell. It is also the gateway to the lower respiratory tract. As such, its job is to condition the air passing through en route to the lungs.
The nose warms air that is cool, adds moisture to air that is dry, and removes particles from air that is dirty. The nasal membranes accomplish all three tasks by producing mucus that is warm, moist, and sticky. Although the nose is a guardian of the more delicate lungs, it is subject to problems of its own.
Viruses, allergies, sinusitis, dust particles, and airborne chemicals can all irritate the nasal membranes.
The membranes respond to injury by producing more mucus — and unlike normal mucus, it's thin, watery, and runny. All that mucus has to go somewhere.
When it drips out the nose, it's a nuisance. But when it drips down the throat, it tickles the nerves of the nasopharynx, triggering a cough. In some cases, the nose itself is to blame rhinitisbut in others, a prolonged postnasal drip lingers after a viral upper respiratory infection; some call this variety a post-infectious cough.
In typical cases, patients with postnasal drip cough more at night, and they are often aware of a tickling feeling at the back of their throats. But they can cough during the day, and their throats may be irritated and sore or perfectly fine.
The best way to find out if a chronic cough is the result of postnasal drip is to try treatment. Nonprescription decongestant or antihistamine tablets are the first step.
Most contain a decongestant such as pseudoephedrine or phenylephrine, an antihistamine such as chlorpheniramine or diphenhydramine, or a combination of the two.
In one form or another, these medications are generally effective and safe, but some people complain of a racing heart and souped-up feeling due to the decongestantwhile others feel sleepy due to the antihistamine.A smoker's cough is generally a wet cough that is productive of phlegm, which can be clear, white, yellow-green or blood tinged.
A smoker's cough can also develop due to chronic bronchitis. Chronic bronchitis is a progressive, recurring inflammation of the lungs, most often due to the damage that long-term smoking causes to the lungs. Stimulation of the cough receptors by dust or other foreign particles produces a cough, which is necessary to remove the foreign material from the respiratory tract before it reaches the lungs.
A long drawn and deep inhalation followed by a complete closure of the glottis, which results in a strong exhalation that suddenly punches the glottis open and sends a blast of air through the upper . N) Why was Cari plagued with a chronic smoker’s cough? Because Cari is a tobacco user this has caused the cilia in her respiratory transitions to go annoyed.
Which anatomic structures in Cari's respiratory system were initially involved? Why was Cari plagued with a chronic smoker's cough? Which damaging effects of tobacco smoke led to Cari's impaired respiratory defense mechanisms? How did pneumonia affect Cari's lung function?
Which anatomical structures in Cari’s respiratory system were initially involved? Nasal. Pharynx. Larynx. Trachea. Right and left primary bronchus.
Lungs. N. Why was Cari plagued with a chronic smoker’s cough? Because of the years that Cari smoked she has smokers cough which is the body’s way of trying to get rid of gunk in the lungs. The infection in Cari’s nasal passages and pharynx was able to spread into her sinuses due to the sinuses being a drainage area for the nasal passages.
B. What is the cough reflex? The cough reflex is used to clear sputum and irritants that are in the nasal passages and pharynx. There are cilia in her trachea that is moving mucus up from the lungs.
