Question
Which of the following are true regarding hyperventilation and exercise?
Hyperventilation helps to compensate for lactic acidosis
Hyperventilation begins as soon as lactate production increases
Hyperventilation facilitates diffusion of oxygen
Hyperventilation is facilitated by increased pulmonary capillary blood flow
Hyperventilation occurs when tidal volume and rate begin to increase

- A. B.Hyperventilation helps to compensate for lactic acidosis
- A. B.Hyperventilation begins as soon as lactate production increases
- A. B.Hyperventilation facilitates diffusion of oxygen
- A. B.Hyperventilation is facilitated by increased pulmonary capillary blood flow
- A. B.Hyperventilation occurs when tidal volume and rate begin to increase
A.correct
B.incorrect
Explanation / Answer
BFALSE ; When the hyperventialtion occurs due to accumulation of more lactate which causes alkalosis not acidosis . A TRUE ; when lactate production increases which tends to hyper ventilate by taking more breathing in short period of time, its due to change in pH levels in the blood B FALSE ; Oxygen concentration remains same, low Co2 levels are reported so the patient is given with rehabiltilation mask to increase CO2 levels, by re breathing A TRUE ; the blood flow in cappilaries are increased by 45mm Hg than normal when hyperventilation. A TRUE The rate and tidal volume increases, upon hyper ventilation the blood pressure increases and rate of repiration also increases.
