Respiratory Control, -Stimulated by noxious gases, smoke, inhaled dusts…

- - - - the function of the brainstem within limits
        
        -Hyperventilation
        
        -Voluntary hypoventilation?
- - - - Response to PH
        
        Response to exercise
        
        -Cortex, impulses from limbs, increase temperature, resetting of CO2 reference level
        
        -Blood gases are normal
        
        -pH is normal except at heavy exercise
        
        Fall in pH with rise in PCO2 --> stimulate ventilation Metabolic acidosis have low pH, low
        
        Response to pH : Peripheral chemoreceptor (carotid chemorece ptors) --> central
        
        chemoreceptor (if the reduction is severe, central chemoreceptor may be stimulated)
      - -Hypoxic response curves. Note that when the Pco2 is 36 mm Hg, almost no
        
        -Only the peripheral chemoreceptors are involved.
        
        -The control becomes important at high altitude and in long-term
        
        hypoxemia caused by chronic lung disease.
    - - -The response is magnified if the arterial Po2 is lowered.
