Flashcards in Chapter 18 Deck (13):
1

Elevated CO2 in body

Hypercapnia

2

Mass balance equation

QO2=A(O2)-V(O2)

3

Mass flow equation

(O2)= CO*[O2]

4

Fick's equation

QO2=CO*(A[O2]-V[O2]

5

Bohr effect

Shift in hemoglobin oxygen saturation due to changes during exercise

6

Factors of Heme saturation

pH down sat down, temp up sat down, PCO2 up sat down, 2,3 DPG up sat down

7

CO2 transporters

Plasma, hemoglobin, bicarbonate

8

Carbonic anhydrase

Converts CO2 to bicarbonate in RBCs

9

Chloride shift

Exchanges Cl- for HCO3- in RBCs

10

Peripheral ventilation controllers

Temp, PO2, PCO2, pH

11

Glomulus cells

Cells that trigger ventilation increase

12

Central controller and where

CO2, medulla

13

Bicarbonate Equation

H2O+CO2H2CO3H+ HCO3-
