Atelectasis | NHLBI, NIH

Atelectasis can happen when there is an airway blockage, when pressure outside the lung keeps it from expanding, or when there is not enough surfactant for the lung to expand normally. When your lungs do not fully expand and fill with air, they may not be able to deliver enough oxygen to your blood. Atelectasis can happen at any age and for different reasons.

How the Lungs Work | NHLBI, NIH

Overview. Your lungs are a pair of organs in your chest. They have a spongy texture and are pinkish-gray in color. When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out).

Lung Inflammation: Symptoms, Causes, Treatment, More

Jul 02, 2020·Sometimes severe lung inflammation can seriously interfere with air and oxygen absorption into your lungs. This can cause effects of hypoxemia (low blood in the lungs) or hypoxia (low blood oxygen in the tissues), resulting in dizziness or loss of consciousness. You will need urgent medical care to manage these consequences.

Heart Rate and Oxygen Consumption | Livestrong

Oxygen consumption, abbreviated VO2, is a measure of the volume of oxygen used by the body. VO2, as described by Dr. Benjamin Levine, is based on the Fick equation, which says oxygen consumption is dependent on the product of oxygen delivery and extraction. Oxygen extraction considers the amount of oxygen in arterial blood that is sent to ...

Interstitial Lung Disease | American Lung Association

Interstitial Lung Disease (ILD) Interstitial lung disease (ILD) is an umbrella term used for a large group of diseases that cause scarring (fibrosis) of the lungs. The scarring causes stiffness in the lungs which makes it difficult to breathe and get oxygen to the bloodstream. Lung damage from ILDs is often irreversible and gets worse over time.
