The control of ventilation during exercise: a lesson in ...

· The Control of Ventilation During Exercise. During submaximal steady-state exercise, increases in ventilation are proportional to the increase in carbon dioxide production (V̇ co 2) and oxygen consumption (V̇ o 2).As such, this tight regulation of ventilation to metabolic rate ensures the homeostasis of the arterial partial pressure of oxygen (P a O 2), carbon dioxide (P a CO 2), and pH.

CO2 Control In School Classrooms - AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...
