Abstract
|
|
|
The physical activity generally decreases after one receives some kind of major thoracic surgery, such as lobectomy or thoracoplasty.
It is the purpose of this report to estimate the physical activity of such patients by examining the cardiopulmonary functions to a known work-load (exercise), and to compare the results with that of healthy persons.
Method:
43 patients were divided into six groups according to the kind and degree of the chest operation, and their ventilatory capacity, blood pressure and heart rate were measured in the resting, light, moderate, and heavy exercise states. The exercise was made by stepping up and down the stairs of 20cm, 30cm, and 40cms height, and from these the amount of external Work was calculated.
The internal work was calculated from \ 02, one litter of V´02 was taken to be equivalent to 4.83 calories and one calorie to be equivalent to 426.4 Kgm-m of work.
14 healthy persons Were examined in a similar way as a control group. Results and Discussion:
In the resting states, there were no significant differences in the ventilatory capacity between the control group and patient groups. The heart rates were increased significantly in VI and VII groups.
During light exercise, the ventilatory capacity was increased in most cases. This increase was higher in the patient groups than in the control group.
The highest recording Was in group VII.
During moderate exercise, the ventilatory capacity was higher than in the resting and light exercise states. In all groups vE Was increased, and highest recording Was in group IV, V, and VI.
During heavy exercise, the ventilatory capacity was higher than in the previous. As before the recording was higher in the patient groups.
In group VII, four out of six patients could not tolerate the heavy exercise.
In group VI and VII, Where there were large amount of lung tissue defects, pulmonary ventilatory
Capacity, and cardiac work was markedly increased, ie, the internal work increased and the work efficiency decreased.
In group VI and VII, the maximum physical ability vas moderate exercise. They could not tolerate heavy exercise because of the decrease in cardiopulmonary function.
