Doctor insights on: Breathing Simulate Chronic Lung Disease Caused Smoking

Share

Lung (Definition)

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

How would breathing through a straw simulate chronic lung disease caused by smoking?

How would breathing through a straw simulate chronic lung disease caused by smoking?

Airflow resistance: Think of the lungs as a giant balloon. The critical point in the system is the neck of the balloon. The narrower the neck, the harder it is for air to flow in and out. In chronic obstructive lung disease the bronchial tubes are narrower due to mucous, swelling, inflammation and sometimes loss of support structures. The straw analogy relates to the airflow limitation through smaller tubes/airways. ...Read more

I was diagnosed with a chronic lung disease at age 10 and needed a transplant. Is it true that it can be hard to find lungs because of size?

Transplant center: The transplant center will list you for the allocation of the new donor lungs. The time that a patient remains on the list prior to finding a donor that is a good match varies and depends on a number of factors. Your age is only one of the factors. It also depends how many other kids your age are waiting. Once a good match is determined, the center moves quickly to perform the transplantation. ...Read more

How is chronic lung disease in infancy diagnosed?

How is chronic lung disease in infancy diagnosed?

The basic concept is that the baby is born premature and requires some form of respiratory support (oxygen, CPAP, mechanical ventilation) at one month of age or beyond 36 weeks corrected gestational age. Chronic lung disease outside of this definition is a less defined phenomenon. ...Read more

Keeping up with her medicines, if any, keeping her doctor's appointments and shots up to date, keeping your home and car smoke-free, and keeping her away from people who have infections are the best things to do to keep her lungs as healthy as possible. Her doctor will wean her oxygen down when it's safe. ...Read more

Why does airway obstruction in chronic lung disease lead to hypercapnia?

Why does airway obstruction in chronic lung disease lead to hypercapnia?

Not alwasy: The more inefficient the damaged lung becomes at eliminating co2 the more you have to work to breath and the more work the more co2 you make. Once co2 is up for a period of time your body stops responding to theco2 &switches to o2 for the drive. Thus co2 rises even more as the body stops response to co2. This makes o2 dangerous to use. Most COPD get no rise in co2. You need a blood test to know. ...Read more
