Upper airway obstruction condition in which sites of anatomic narrowing such as the hypo pharynx at the base of the tongue and the false and true vocal cords at the laryngeal opening are obstructed.

Vasogenic edema an accumulation of fluid in the cerebrum that is typically caused by an increase in capillary endothelial cell permeability and usually occurs near a tumor.

Ventilation-perfusion ratio (V/Q) the relationship between ventilation and blood flow in the lung that is measure by calculating the difference between the alveolar and arterial partial pressured of oxygen.

Ventricular septal defect a congenital malformation in which the wall between the left and right ventricles has a hole that allows blood to travel between the left and right ventricles potentially leading to congestive heart failure.

Vital capacity Maximal amount of air that can be taken in and exhaled with forceful expiration.

Von Willebrand disease an inherited disease in which the von Willebrand factor proteins that are made in the blood vessel and function to control platelet activity are abnormal or absent resulting in a tendency to hemorrhage.

Wheezing is a continuous, high pitched, whistling sound; it is significant for obstruction or tightness in the small airways.

Hemoglobin the iron-containing oxygen-transport metalloprotein in the red blood cells. Transports oxygen from the lungs to the rest of the body.

Hematocrit also called packed cell volume (PCV), is the proportion of blood volume that is occupied by RBCs. 47% in men, 42% in women.

Paroxysmal nocturnal dyspnea (PND) waking up suddenly during the night, feeling short of breath.

Parasympathetic nervous system division of the ANS cardiac muscle, smooth muscle, glandular tissue, “rest and repose”.

Ventilation, diffusion, perfusion, respiration 4 major processes occuring as you breathe.

Ventilation process of moving air into and out of the trachea, bronchi, and lungs

Diffusion process of moving and exchanging the oxygen acquired during ventilation and carbon dioxide waste across the alveolar capillary membranes.

Perfusion process of supplying oxygenated blood to the lungs and organ systems via the blood vessels.

Respiration process in which cells throughout the body use oxygen aerobically to make energy.

Tidal Volume is the amount of air that is exhaled after passive inspirations: this is the volume of air going in and out of the lungs at rest; in adults, this volume is approximately 500 cc.

Vital Capacity is the maximal amount of air that can be moved in and out of the lungs with forced inhalation and exhalation.

Forced vital capacity is the maximal amount of air that is exhaled from the lungs during a forced exhalation.

Forced expiratory volume in 1 second (FEV1) the maximal amount of air that can be expired from the lungs in 1 second.

Residual volume the volume of air that remains in the lungs after maximal expiration.

Total lung capacity (TLC) the total amount of air in the lungs when they are maximally expanded and is the sum of the vital capacity and residual volume.

Acute characterized by sudden onset

Aerobe An organism that lives in an oxygen environment

Ambulatory Able to walk

Anaerobe An ogranism that lives in an oxygen free environment

Anaplasia The irregular structural characteristics of a cell that identify it as a malignant cancer cell

Anomaly An abnormal occurance especially in reference to birth defects

Antiboiotic A chemical substance derivable from a mold or bacterium that kills microorganisms & cures infections

Antibody A protein produced by the body as part of its defense against foreign bacteria or blood cells

Antisepsis The prevention of sepsis by excluding or destroying microorganisms

Antiseptic A substance that kills or prohibits the growth of microorganisms

Asepsis Free from germs

Atrophy A wasting away or...
