When carbon dioxide (CO2) levels rise in the bloodstream, the respiratory rate typically increases. This response is triggered by the body's need to expel excess CO2 and maintain acid-base balance. The brain detects elevated CO2 levels through chemoreceptors, stimulating the respiratory centers to enhance breathing frequency and depth, thereby facilitating greater gas exchange in the lungs. This helps to lower CO2 levels back to normal.
Why does the respiratory rate change depending on age?
When the level of arterial carbon dioxide rises above normal, it can lead to respiratory acidosis, which is a condition where the blood becomes too acidic due to excess carbon dioxide. This can cause symptoms such as confusion, headaches, and breathing difficulties. It can also lead to complications if not treated promptly.

When the price level and the money wage rate change by the same percentage, the real wage rate remains constant at its full employment equilibrium level so employment remains constant and real GDP remains constant at "potential GDP" which is the quantity of real GDP at full employment.

The respiratory rate refers to the number of breaths a person takes per minute. For adults, a normal resting respiratory rate typically ranges from 12 to 20 breaths per minute. This rate can vary based on factors such as age, fitness level, and overall health. Monitoring respiratory rate is important, as significant deviations can indicate respiratory or systemic issues.
