Practical lab classes-breathing II Flashcards
What is STPD?
Standard Temperature and Pressure for a Dry Gas
What is the Haldane Transformation?
The assumption that only O2 and CO2 are exchanged in the lungs
What is assumes about non O2/CO2 gases in the Haldane Transformation?
They have the same volume in both inspiratory and expiratory gases
What is the haldane transformation use to caculate?
VI from VE
What property does N2 have that means the mass inspired is the same as expired?
It is metabolically inert
What is FIN2 in the haldane transformation?
Fraction inspired nitrogen
What is VI in the haldane transformation?
Total volume inspired
What is FEN2 in the haldane transformation?
Fraction expired nitrogen
What is VE in the haldane transformation?
Total volume expired
How can N2% be calculated for the haldane transformation?
100%-O2%-CO2%
How can RER be calculated?
Dividing CO2 production by O2 consumption.
What is the RER when CHO is the substrate?
1
What is the RER when fat is a substrate?
0.7
