What is the medical term meaning voluntary increase in the rate and depth of breathing? What factors are most important in triggering the changes in breathing rate? Chemicals - most important are the concentrations of CO2, hydrogen  ions and O2 in the blood. Chemoreceptors are located in the  respiratory center, the carotid bodies and tâ¦he aortic bodies which  detect the levels.
Normal Respiratory Pattern. : Expiration more or less equal to inspiration in depth (amplitude); expiration longer than inspiration; rate (frequency) about 10-20 breaths/min. (Normal ranges listed vary from 13-18 breaths/min. to 5-22 breaths/min.).Hyperventilation.: Lowers the PCO2 in blood, which increases the blood pH. Expiration more or less equal to inspiration in depth (amplitude); expiration longer than inspiration; rate (frequency) about 10-20 breaths/min. (Normal ranges listed vary from 13-18 breaths/min. to 5-22 breaths/min.). Hyperventilation.
