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.
Arterial Blood Gas Interpretation. (ABG) Arterial Blood Gas Analysis is used to measure the partial pressures of oxygen (PaO2), carbon dioxide (PaCO2), and the pH of an arterial blood sample. Oxygen content (O2CT), oxygen saturation (SaO2), and bicarbonate (HCO3-) values are also measured. A blood sample for ABG analysis may be drawn by percutaneous arterial puncture from an arterial line. The ABG analysis is mainly used to evaluate gas exchange in the lungs. It is also used to assess integrity of the ventilatory control system and to determine the acid-bas level of the blood. The ABG analysis is also used for monitoring respiratory therapy (again by evaluating the gas exchange in the lungs).
