Explanation / Answer
1. Hypoxia stimulates Hyperventillation.
Hypoxia is formation of low oxygen condtions in the body. Acute hypoxia stimulates the sympathetic system while depressing the parasympathetic nervous system. This change is sensed by the autonomic nervous system. It responds by increasing ventilation.
2. A common cause of hyperventillation is anxiety.
Hyperventillation refers to an increased breathing rate or over-breathing. More amount of ixygen is taken within the body than normal. As the result, carbon dioxide levels in the body may decrease as there is less time for the body to retain it. The body enters into a fighting mode when there is anxiety. Inhaling more oxygen will further incraese the anxiety or panic attack.
3. Drugs that depress the neurons that drive ventilation will cause hypoventilation.
Drugs such as opioids bind to the receptors on the neurons involved in ventilation preventing neurotransmitter release. As a result, oxygen saturation decreases in the blood, carbon dioxide levels will rise. Such an effect results in hypoventilation.
4. Hypoventilation causes the PaCO2 to increase.
When there is hypoventilation, the amount of oxygen inhaled is less. As a result, levels of carbon dioxide will rise in the body. In hypoventilation, PaCO2 will be more than 45mm Hg.
5. Depending on its location and the individual’s response, pain may cause either hypoventilation or hyperventilation.
During a heart attack, flow of oxygen to the heart reduces. Due to reduced oxygen levels in the heart, there may be muscle cramps in heart due to reduced blood flow, causing pain. Pain will result in increased blood flow to the organ, resulting in increased breathing.
Pain can cause an increase in skeletal muscle tension. This reduces total lung compliance, causes hypoventilation
6. The technical term for an increased PaCO2 is Hypercapnia.
Hypercapnia is a condition wherein there is increased level of carbon dioxide ib blood. As a result, the PaCO2, partial pressure of carbon dioxide will rise above 45mm Hg.
