1. Hypoxic drive

   Hypoxic drive refers to a regulatory mechanism within the respiratory system that balances breathing based on the levels of oxygen in the bloodstream. It is an alternate control system that becomes active in individuals with certain chronic lung diseases, such as chronic obstructive pulmonary disease (COPD). Normally, the respiratory drive is primarily controlled by high levels of carbon dioxide (CO2) in the blood, but in hypoxic drive, the respiratory centers in the brain become more responsive to low levels of oxygen (hypoxia). This shift in control can help maintain adequate oxygen levels in the blood even when the CO2 levels are high, allowing individuals with chronic lung diseases to tolerate higher levels of CO2. However, hypoxic drive can be compromised in some individuals with COPD, leading to hypercapnia (excess CO2 in the blood) and respiratory failure.

1. Hypoxic drive

   The hypoxic drive is a form of respiratory drive in which the body uses oxygen chemoreceptors instead of carbon dioxide receptors to regulate the respiratory cycle. Normal respiration is driven mostly by the levels of carbon dioxide in the arteries, which are detected by central chemoreceptors, and very little by the oxygen levels. An increase in carbon dioxide will cause chemoreceptor reflexes to trigger an increase in respirations. Hypoxic drive accounts normally for 10% of the total drive to breathe. This increases as the PaO2 goes to 70 torr and below, while hypoxic drive is no longer active when PaO2 exceeds 170 torr. The hypoxic drive is so weak that unconsciousness will develop before respiratory distress is noted and is therefore a risk for pilots flying at high altitudes. For this reason, supplemental oxygen is required by Federal Aviation Regulations for pilots flying above about 12,500 feet altitude in unpressurized airplanes. In the past, it was believed that in cases where there are chronically high carbon dioxide levels in the blood such as in COPD patients, the body will begin to rely more on the oxygen receptors and less on the carbon dioxide receptors. And that in this case, when there is an increase in oxygen levels the body will decrease the rate of respiration.
