O2 Transport


oxygen enters the plasma and maintains molecular struture and moves freely throughout the plasma Dissolve
Hemoglobin is bound with O2 Oxyhemoglobin
Hemoglobin id NOT bound with O2 Deoxyhemoglobin
Different amino acid, RBCs are sickle-shaped Sickle cell hemoglobin
Has a greater attraction to O2 Fetal Hb
Means attraction to like molecules Affinity
Pco2 level increases, oxyhemoglobin saturation decreases shifting curv to the right, Pco2 level decreases shifting curve to the left Bohr Effect
Effects of Pco2 and pH on the oxyhemoglobin curve Bohr Effect
Carbon monoxide is bound to hemoglobin Carboxyhemoglobin
cardiac output that moves from right side of heart to the left side without being exposed to alveolar oxygen Pulmonary Shunting
Has two major categories: anatomic shunts and capillary shunts Absolute Shunt
Also called true shunts Anatomic and Capillary shunts
Blood flows left to right side of heart without coming in contact with alveolus for gas exchange Anatomic shunt
A healthy lung normal anatomic shunting of cardiac output 3%
A shunt that can be treated with oxygen, is caused by aveolar collapse or atelectasis Capillary shunts
Pulmonary capillary perfusion is excess of alveolar ventilation, CAN NOT be treated with oxygen Relative shunt
