Difference between bronchial asthma, chronic bronchitis and emphysema in terms of lung?

Difference between bronchial asthma, chronic bronchitis and emphysema in terms of lung?

Difference...: Asthma is characterized by recurrent, reversible airway obstruction. Emphysema and chronic bronchitis are both forms of COPD and are characterized by irreversible airway obstruction usually caused by smoking. Now, COPD patients can also have a reversible airway obstruction component and asthmatics can develop an irreversible component over time so there is overlap in this definition. ...Read more

What is the capacity of asthmatic lungs vs non asthmatic lungs?

What is the capacity of asthmatic lungs vs non asthmatic lungs?

Lung capacity/asthma: Total lung capacity is the volume of air in the lungs at the end of maximal inspiration. Asthmatics can have higher lung volumes than normal people because their lungs become hyperinflated when they have attacks. They have trouble breathing all the way out, so the volume left over afterward, the residual lung volume, is also elevated. In severe asthmatics, fibrosis/scars can decrease volumes. ...Read more

Is there association between asthma, bronchitis, chronic sinusitis, respiratory tract infection and pulmonary hypertension?can they affect each other?

Is there association between asthma, bronchitis, chronic sinusitis, respiratory tract infection and pulmonary hypertension?can they affect each other?

Lung conditions : The conditions you mentioned affect lungs and linings of upper respiratory airways; they are apparently not inter-related. That said, some patients with chronic bronchitis may get frequent respiratory tract infections. One of the late and severe complications from chronic bronchitis can be pulmonary hypertension but there are other causes for the condition. ...Read more

Which of these are restrictive: obstructive pulmonary diseases are asthma, chronic bronchitis and emphysema?

Which of these are restrictive: obstructive pulmonary diseases are asthma, chronic bronchitis and emphysema?

Restriction: Airway "obstruction" refers to limitation of air flow through the airways. "restriction" refers to processes that keep the lungs from opening fully when you inhale. Restriction can result from fibrosis, or thickening, of the lung as with diseases like idiopathic pulmonary fibrosis. It can even be from something as simple as obesity or muscle weakness that keeps you from breathing deeply. ...Read more

In status asthmaticus, what is the cause of inspiratory wheezing?

In status asthmaticus, what is the cause of inspiratory wheezing?

Airway constriction: With any asthma attack, the airway is constricted, which increases the flow velocity and causes the noise, which we call wheezing. Of course the real problem is the increased work of breathing and decreased oxygenation. Medications open the airway, decreasing the flow velocity, reducing the noise and allowing you to breath easier. ...Read more

Are bronchial pneumonia and bronchitis with pneumonia the same?

Are bronchial pneumonia and bronchitis with pneumonia the same?

No: Pneumonia denotes infection in the lung parenchyma (lung tissue). Bronchits denotes infllamation in the bronchilal airway. Pneumonia is a more serious condition.

Asthma: Bronchial Asthma, asthmatic bronchitis and asthma are the same. A typical trigger of an acute asthma exacerbation (flare up) is the cold virus so sometimes asthmatic bronchitis is used by some clinicians.
