The value of 4.0 g-cm/ml (= 2s) is discussed as a limit to a pathological increase. With a rise in breath volume, relative weight and also, marginally, the spontaneous resting breath frequency, a significant increase of ventilatory work of breathing in normal persons must be anticipated.ith a rise in breath volume, relative weight and also, marginally, the spontaneous resting breath frequency, a significant increase of ventilatory work of breathing in normal persons must be anticipated.
Family Systems Theory. The family systems theory is a theory introduced by Dr. Murray Bowen that suggests that individuals cannot be understood in isolation from one another, but rather as a part of their family, as the family is an emotional unit.
Family Systems theorists pay careful attention to the boundaries between family members, because such boundaries are exactly where problems tend to manifest. A boundary is a sort of psychological perimeter and definition that people draw around themselves, and around particular relationships they are involved in.
