122 Tables, Factors, and Formulas for Computing Respiratory 



TABLE 28. 



Calories per square meter of body-surface (height-weight formula) per hour, 



Aub and Du Bois standards. 



TABLE 29. 

 Formulas for predicting basal metabolism of males and females. (Dreyer.) 



Males: 

 C = 



0.1015 X A- 

 C = calories per 24 hours. 

 W = body- weight in grams. 

 A =age in years. 



Females: 



= 0.1125 x^- 1333 

 C = calories per 24 hours. 

 W = body- weight in grams. 

 A =age in years. 



TABLE 30. 



Weights of gases at C. and 760 mm. pressure, at sea-level and 45 

 latitude, and their equivalent volumes. 



1 liter of oxygen = 1 . 4292 grams 



1 liter of carbon dioxid = 1 . 9652 grams 



1 liter of nitrogen = 1 . 2542 grams 



1 liter of air = 1 .2928 grams 



1 liter of water vapor = 0.8 132 gram 



1 liter of hydrogen =0.09004 gram 



1 gram of oxygen = . 6997 liter 

 1 gramof carbon dioxid = 0. 5089 liter 

 1 gram of water vapor = 1 . 2440 liters

 Reciprocal value of weight per liter. 



Do. 



Calculated on the assumption that a gram 

 molecule of water vapor occupies 22.412 liters 

 at C. and 760 mm.,i. e., it acts as a perfect 

 gas.
