Copd (Definition)

COPD may include chronic bronchitis, emphysema, or both. Chronic bronchitis is the production of increased mucus caused by inflammation. Bronchitis is considered chronic if you cough and produce excess mucus most days for three months in a year, two years in a row. Emphysema is a disease that damages the air sacs and/or the smallest breathing tubes in the lungs. ...Read more

Bronchoconstriction (asthma/copd) affects breathing out during expiration, but not breathing in during inspiration, how come?

Bronchoconstriction (asthma/copd) affects breathing out during expiration, but not breathing in during inspiration, how come?

Dynamic collapse: This is a fancy term of when airway pressure is more on the outside of your airways and collapses as you exhale. This pressure difference happens at different stages of exhalation in copd. With asthma there is narrowing of your airways from inflammation so this constricts the diameter and makes this worse. All due to airway pressure and "equal pressure point". Hope this helps! ...Read more

Is Chest expnasion of 5cm (currently 3cm while inhalation) while inhalation possible by deep breathing exercises using lung exerciser in 1-2 months?

Is Chest expnasion of 5cm (currently 3cm while inhalation) while inhalation possible by deep breathing exercises using lung exerciser in 1-2 months?

Chest expansion: Hello ~ your question as written is difficult to understand but if I do, you are asking if your lungs vital capacity will improve with deep breathing and lung exerciser. Yes it will but to a max predetermined by your body size When the chest gets bigger for body builders that is muscle on the outside and not much increase in lung volumes. If that does not answer resubmit question thx ...Read more

How can pursed lip breathing reduce the symptoms of an asthma attack?

How can pursed lip breathing reduce the symptoms of an asthma attack?

Obstruction...: In an asthma attack, there is airway obstruction so expiration becomes difficult and, eventually, there is an increase in carbon dioxide since it can't be expired. Pursed lip breathing prolongs the expiratory phase of respiration so that, potentially, more air and carbon dioxide can be exhaled. That way, there is more room for oxygen to be inhaled. ...Read more

My chest x-ray shows hyperinflated lungs. Can anxiety cause air trapping from poor breathing?

My chest x-ray shows hyperinflated lungs. Can anxiety cause air trapping from poor breathing?

NO: Air trappin is generally due to air OBSTRUCTION in the smaller lung (bronchial) tubes. S guess a VERY DEEP Breath ...held while the xray is taken could give an appearance of hyperinflation but Radiologist know the difference!!! BTW anxiety generally is associated with rapid shallow breathing...Hope this helps! Dr Z ...Read more

Why is breathing in during inspiration not affected by bronchoconstriction (asthma or copd)?

Why is breathing in during inspiration not affected by bronchoconstriction (asthma or copd)?

Pressure.: Long story...essentially, the pressure pushing upon the airways with expiration causes the airways to close upon themselves, causing air trapping which is one of the hallmarks of COPD and the other obstructive lung diseases. ...Read more

My Daughter is experiencing wheezing (worsened by: breathing in cold air, lying flat, exposure to secondhand smoke, in the evening, at night) .

My Daughter is experiencing  wheezing (worsened by: breathing in cold air, lying flat, exposure to secondhand smoke, in the evening, at night) .

Secondhand smoke: The most important intervention is the elimination of secondhand smoke. Children who live with smokers have a higher rate of asthma and more severe asthma symptoms. Secondhand smoke spreads throughout a living space so smoking must stop in entire living space. The car also needs to be smoke free. Follow up with doctor as child may still need medication for the wheezing. ...Read more

Difficulty breathing through nose related to snoring?

Yes: The airway ideally includes nasal breathing. When air goes through the nose and then behind the throat and into the lungs there is usually less obstruction. When your nose is blocked and you mouth breath there is more obstruction. ...Read more

Explain this? Lip pursing annoying habit can actually increase end-respiratory pressure (the eep of peep) and improve gas exchange in lungs. Thanks.

Recruitment: By increasing end expiratory pressure, you stent your airways more open and can recruit alveoli for better gas exchange. This is the basis for the classic "pink puffer" variant of copd. ...Read more

Can breathing in cold air damage your health?

Can breathing in cold air damage your health?

Possibly if you have: Asthma. Cold, dry air ^’s nasal mucus production & viscosity. Mucus is part of our body’s defense mechanism. It traps viruses & other particles. When the mucus is thick (sluggish) it makes removing viruses more difficult. Another function of the nose is to warm cold air before it moves to the lungs. Capillaries in the nose dilate to bring warm blood to the nares. As these tissues fill with blood. ...Read more

Lungs in fluid , problem in breathing and cuffing?

Lungs in fluid , problem in breathing and cuffing?

Several causes: Fluid in lungs can be due to several causes & it should be investigated by your doctor to determine appropriate therapy. Because the retained fluid in your lungs makes your lungs relatively stiff & makes it harder for oxygen to enter your body, it will lead to problems with breathing as the body tries to make up for this by breathing faster. Please consult a lung specialist for treatment. ...Read more
