Changes in pulmonary elastic and resistive properties, and in maximum expiratory flow with increasing age, were first described 40 yrs ago, admittedly by small cross-sectional studies of young adults versus elderly subjects. A decreased vital capacity is an indication of restrictive lung disease where the lungs cannot expand completely. Explain how hyperventilation and hypoventilation alter levels of carbon dioxide in the blood. In addition, explain how it knows when to slow down your breathing rate. Clinical studies indicate that minute ventilation starts increasing exponentially once arterial PO2 is reduced to 60 mmHg. A persons stroke volume will also increase as an increase in blood plasma and blood volume occur and reduced heart rate which increases the diastolic filling time.
