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.
