The respiratory system is the primary interface for inhaled compounds and the center for gas exchange in the body. Alveoli are tiny, balloon-shaped structures that allow the rapid exchange of oxygen and carbon dioxide between the lungs and pulmonary capillaries Fig. For gas exchange to occur, the molecules must be capable of traversing three structures: the alveolar epithelium, the interstitial space, and the capillary endothelium. If ventilation is reduced because of lung disease, or perfusion is decreased through small-vessel vasculitis, lung function is impaired. In addition, inhalation of foreign particles or infection can cause inflammation and mucus production, which may act as potential barriers to gas exchange if these secretions are found on the respiratory surfaces.

Bronchitis can be divided into two categories, acute and chronic, each of which has different etiologies, pathologies, and therapies.

Chronic bronchitis is a type of COPD chronic obstructive pulmonary disease. COPD is a group of lung diseases that make it hard to breathe and get worse over time. The other main type of COPD is emphysema. Most people with COPD have both emphysema and chronic bronchitis, but how severe each type is can be different from person to person. Chronic bronchitis is inflammation swelling and irritation of the bronchial tubes. These tubes are the airways that carry air to and from the air sacs in your lungs.

Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Diagnosis is often based on symptoms and physical examination. Risk factors for pneumonia include cystic fibrosis , chronic obstructive pulmonary disease COPD , sickle cell disease , asthma , diabetes , heart failure , a history of smoking , a poor ability to cough such as following a stroke , and a weak immune system. Vaccines to prevent certain types of pneumonia such as those caused by Streptococcus pneumoniae bacteria or that linked to influenza are available. Treatment depends on the underlying cause.

Bronchitis or Pneumonia?

Patient information : See related handout on acute bronchitis , written by the authors of this article. Cough is the most common illness-related reason for ambulatory care visits in the United States. Acute bronchitis is a clinical diagnosis characterized by cough due to acute inflammation of the trachea and large airways without evidence of pneumonia. Pneumonia should be suspected in patients with tachypnea, tachycardia, dyspnea, or lung findings suggestive of pneumonia, and radiography is warranted. Pertussis should be suspected in patients with cough persisting for more than two weeks that is accompanied by symptoms such as paroxysmal cough, whooping cough, and post-tussive emesis, or recent pertussis exposure. The cough associated with acute bronchitis typically lasts about two to three weeks, and this should be emphasized with patients. Acute bronchitis is usually caused by viruses, and antibiotics are not indicated in patients without chronic lung disease.

Bronchitis and Pneumonia

Bronchitis is a swelling of the bronchi, the airways that lead to your lungs. The most common symptoms are coughing and mucus, but you may also have wheezing, shortness of breath, chest pain, and a slight fever. Bronchitis is usually caused by cold or flu viruses, but occasionally a bacterial infection may be the culprit.

Is It Bronchitis or Pneumonia?

Acute bronchitis and pneumonia are often confused because they cause such similar symptoms. A cough that lasts for weeks or even longer are hallmarks of both illnesses.

Он знал, что это трюк. Корпорация Нуматек сделала очень крупную ставку на новый алгоритм Танкадо, и теперь кто-то из конкурентов пытается выведать ее величину. - У вас есть ключ? - сказал Нуматака с деланным интересом.

Увы, это было невозможно. Чаша быстро приближалась к нему справа. Люди отпивали по глотку вина, крестились и поднимались, направляясь к выходу. Хорошо бы помедленнее.

most often a bacterial or viral infection that causes swelling.
