Rapid increase of organic acid in the body?
Rapid increase of organic acids in the body you would expect to observe the increase in your heart rate. You would also observe increased alveolar ventilation, decreased blood pH and increased in blood pressure.
The central chemoreceptors will increase their firing rate in direct response to increases in the level of in the CSF resulting in ventilation?
carbon dioxide; increased
Why does pulmonary ventilation increase?
Pulmonary ventilation is the volume air that is breathed in or out in a single minute. It is the sum of the tidal volume (volume of air per breath) and the ventilation rate (the number of breaths per minute). For an individual's pulmonary ventilation to increase, there must be an increase in at least one of these two values. The individual can begin breathing deeper at the same rate (increasing tidal volume) or the individual can begin breathing faster at the same volume (increase ventilation rate) or both.
Is Alveolar PCO2 identical to atmospheric PCO2?
No, it is higher or the CO2 would not move out of the lungs.
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
How does exercise affect pO2 in the muscle cell?
Arterial po2 will not change because it's almost at maximum already. Venous po2 will decrease due to increased oxygen consumption by respiring muscle. Venous and arterial pCo2 will actually either stay the same or fall due to the increased ventilation stimulated by the increased Co2 production by respiring muscles. The increased pCO2 is detected by central and peripheral chemoreceptors and leads to increased ventilation, resulting in increased ventilation - causing pCo2 to remain normal or decrease. This mechanism cannot be used to explain the ventilation increase in light exercise because pCo2 hardly rises at all during light exercise, therefore the chemoreceptors may not be responsible for the mechanism resulting in increased ventilation,
The strongest stimulatory effect on pulmonary ventilation is?
PCO2 of the blood. Co2 removal is the biggest reason for breathing.
What is the effects of an increase in PCO2?
Plasma pH will Decrease
A 10 percent increase in the level of carbon dioxide in the blood will?
Will decrease the blood pH causing increased ventilation.
Does breathing rate increase or decrease when arterial PCO2 increases?
increases
Rapid increase of organic acid in the body?
Rapid increase of organic acids in the body you would expect to observe the increase in your heart rate. You would also observe increased alveolar ventilation, decreased blood pH and increased in blood pressure.
The central chemoreceptors will increase their firing rate in direct response to increases in the level of in the CSF resulting in ventilation?
carbon dioxide; increased
What factors affect the release of oxygen from oxyhemoglobin?
-Decreased pH -Increased Temperature -Increased Pco2
In COPD the PaCO2 will increase but the ventilation will not increase why?
ecause of air trapping and ineffective alveolar ventilation
How does increased ventilation rate affect arterial blood?
It will induce a respiratory alkalosis, as carbon dioxide is washed out of the blood by the increased ventilation rate.
Is hypoxia a cardiac arrhthmia?
Hypoxia-->pCO2 increase-->chemoreceptors are stimulated-->VMC stimulated-->trachyarrythmia
Hypercapnia causes minute ventilation to?
increase as the minute ventilation is the amount of carbon dioxide
