Pulmonary System Flashcards
1
Q
What factors increase DLCO?
A
Exercise, increased alveolar PCO2, supine position
2
Q
What is the time course of TRALI?
A
Hypoxia and pulmonary edema within 6 hours of transfusion
3
Q
What percentage of patients have the RUL opening off the trachea?
A
2-3%
4
Q
How do you calculate dead space volume?
A
Bohr equation: Vd/Vt = (PaCO2 - PeCO2)/PaCO2
5
Q
What is the Bohr effect?
A
Shift of the oxyhemoglobin dissociation curve to the right in the presence of 2,3-DPG to facilitate oxygen unloading
6
Q
What is the Haldane effect?
A
Increased affinity for CO2 of deoxyhemoglobin compared to oxyhemoglobin
