BCEN- respiratory Questions and answers, 100% Accurate. VERIFIED. ventilation - -movement of air in and out of the lungs Diffusion - -the process by which molecules of gas move from an area of higher concentration to an area of lower concentration (alveolar and capillary). if ventilation & perfusion match you get diffusion. If they don't match- VQ mismatch Perfusion (Q) - -the process of transporting gases to the body (capillary) via the circulatory system. dead space ventilation - -alveoli receiving ventilation but not perfusion (pulmonary emboli) ... aka air no blood intrapulmonary shunting - -alveoli receiving perfusion but not ventilation (atelectasis, pneumonia) ... aka blood no air Cheyne-Stokes respiration - -pattern of breathing characterized by a gradual increase of depth and sometimes rate to a maximum level, followed by a decrease, resulting in apnea (cyclic crescendo) Central neurogenic hyperventilation - -a pattern of rapid and deep breathing caused by injury to the brain apneustic breathing - -Abnormal respiration marked by prolonged inspiration; accompanies damage to upper pons. kussmaul's respirations - -Respirations that are regular but abnormally deep and increased in rate, seen in metabolic acidosis (DKA), blowing off excess co2
