WebMinute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels. Weba graphical recording of an organism's respiratory function, including volumes and capacities Tidal volume is the: volume of air inhaled/exhaled during normal breathing Ventilation (inhalation/exhalation) in humans and other vertebrates is primarily through flow from high to low pressure What is the physical process by which gas exchange occurs?
