Minute Ventilation in Health and Disease
Minute volume is connected with tidal volume and breathing frequency using the following simple formula:
Average minute ventilation for a person changes throughout the day depending on many factors.
What about minute ventilation in people with chronic diseases?
For example, for people with mild forms of diabetes, asthma, COPD, heart disease, cancer, and many other conditions have about 12-18 L/min for their minute ventilation at rest indicating reduced CO2 values 24/7.
Therefore, they suffer from overbreathing. Detailed medical references can be found on pages of NormalBreathing.com.
However, breathing slower during exercise, with muscle relaxation, helps to increase arterial CO2 (most potent vasodilator), reduce heart rate and improve O2 delivery to body tissues.
