O2 Transport
RESP
Question | Answer |
---|---|
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 |
