An amazing song by Vampire weekend :]] (Made for Nick and Norah's Infinite Playlist). Lyrics: Ottoman couch, how handsome your furniture. Lovelier now, but dressed for a funeral.
Chronic Obstructive Pulmonary Disease (COPD) Definition: Arterial blood gases (ABGs) are diagnostic tests performed on blood taken from an artery which contains oxygen and carbon dioxide. The Purpose of the ABG. ABGs measure how well the lungs can provide adequate oxygen to the body and subsequently remove carbon dioxide. Analysis of blood gases helps evaluate a person's respiratory and metabolic status. ABGs also measure blood pH and the integrity of the body's acid-base balance.
Oxygen and carbon dioxide are two invisible gases in air. The secret to doing this job is BLOOD .The air in your alveoli sends oxygen into your blood. Your blood flows through a system of tubes called blood vessels. First, blood full of oxygen goes to your heart. Your heart is like a big pump. It sends the oxygen-filled blood whooshing off to all parts of your body.   The blood vessels that deliver oxygen are called arteries.
