Answer :
Final answer:
Excessive ventilation can be dangerous as it may reduce the surface area for gas diffusion, disrupt the balance of oxygen and carbon dioxide levels, create physiological shunt, increase the respiration rate, and can cause conditions like hyperpnea.
Explanation:
Delivering excessive ventilation can become dangerous as it might severely impact breathing. This happens because high ventilation rates may reduce the surface area available for gas diffusion, decreasing the amount of oxygen and increasing the carbon dioxide level in the blood. This situation creates 'anatomical' or 'physiological dead space' where no ventilation and/or perfusion occurs, impairing lung function
A physiological shunt may develop due to excessive ventilation if there's an infection or edema in the lung obstructing an area. This will decrease ventilation but won't affect perfusion, thereby changing the V/Q ratio and affecting gas exchange.
Hyperpnea, or the increased rate and depth of ventilation due to an increase in oxygen demand, is a condition that does not significantly alter blood oxygen or carbon dioxide levels, but can be harmful if caused by excessive ventilation.
The rate of respiration changes based on the ventilation rate. With high ventilation, the respiratory rate will increase while the volume of air per breath decreases causing an imbalance in oxygen and carbon dioxide levels in the body. This irregular breathing pattern can lead to unconsciousness or even fatal conditions if not treated promptly.
