Asphyxia Definition and Information

Definition of Asphyxia The inability of the LUNGS to take in air or conduct the OXYGEN-CARBON DIOXIDE EXCHANGE, depriving the body of oxygen. Asphyxia is a life-threatening emergency that requires immediate medical treatment. The emergency may occur as a consequence of water or other fluids in the lungs (drowning) that results in suffocation (inability of air to enter the […]

Interstitial Lung Disease – Symptoms and Treatment

Definition of Interstitial Lung Disease Interstitial Lung Disease is a broad term for chronic conditions that restrict the ability of the LUNGS to function properly, encompassing more than 150 diseases. Interstitial lung disorders, also called interstitial lung disease as a collective term, are typically obstructive, fibrotic (involve SCAR formation), and progressive. Many arise from occupational exposures such as […]

Tachypnea Definition

Definition of Tachypnea Tachypnea is an abnormally rapid RESPIRATION RATE. BREATHING is also usually shallow. The normal respiration rate for healthy adults is 15 to 20 respiratory cycles per minute. In tachypnea the respiration rate can be two to four times normal. Breathing may appear labored, and when the body is not able to meet its needs the person […]
