Pertussis Lungs And Breathing
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
Cardiology tests seem in clear but pulm CT scan of chest showed hyperinflated lungs and breathing function test was poor. What is next step?
Breathing sounds: With severe croup, you may hear stridor, which is an inspiratory sucking or squeaking sound. This is a sign of severe tracheal narrowing and warrants immediate medical attention. With pertussis, there are many coughs in a row (>5) which makes it hard to breath in between. Sometimes there's a whooping sound after the cough attack.

Passively relaxing these muscles allow exhalation. You can also force your breath out actively but this is not normally necessary. ...Read more

Chronic aspiration can cause pulmonary fibrosis (as one of the contributing theories/factors) even cause bronchiectasis or rupture of lung tissue. Barium swallow or direct visualization are few of the tests. ...Read more

Belly breathing: Breathing from the abdominal cavity is very helpful because even though it does not increase actual lung size, it gives lungs room to open up.
