Rapid breathing can lead to a condition called hyperventilation. Hyperventilation occurs when a person breaths more rapidly than the body demands. When a person hyperventilates, the CO2 blood concentration (partial pressure) decreases below normal levels.

What to happens to breathing rate during jumping jacks?
Increases due to greater oxygen demands and a rising blood CO2 concentration (PCO2).
Does breathing rate increase or decrease when arterial PCO2 increases?
increases
What happens to Pco2 levels with hyperventillation?
When a person is hyperventilating, the PCO2 decreases. This is because a person is breathing enough to expel the CO2 out of the lungs making it decrease.
The strongest stimulatory effect on pulmonary ventilation is?
PCO2 of the blood. Co2 removal is the biggest reason for breathing.
What factors affect the release of oxygen from oxyhemoglobin?
-Decreased pH -Increased Temperature -Increased Pco2
What gas level does the body respond to more often to control breathing?
The body responds first to the partial pressure of carbon dioxide in the blood. PCO2)
Is Alveolar PCO2 identical to atmospheric PCO2?
No, it is higher or the CO2 would not move out of the lungs.
What regulates activities?
pco2
The relative PO2 and PCO2 in pulmonary arteries and veins and systemic arteries and veins?
Pulmonary artery/Systemic veins PCO2 = 45 PO2 = 40 Pulmonary vein/Systemic arteries PCO2 = 40 PO2 = 100
When PCO2 declines bronchioles?
constrict
What type of membrane used in po2 and pco2 electrode?
Teflon is used for the membrane of pco2 electrodes as it allows for the diffusion of co2 but not ions.
What are the units for pCO2?
mm Hg (mercury)
