Clinical value of rebreathing test in obstructive lung diseases.

The ventilatory response to CO2 inhalation, using rebreathing method, was studied in normal subjects and in patients with bronchial asthma and chronic obstructive lung disease. The patients with lung disease had flatter CO2 response curves. However, it the ventilation was expressed as a fraction of the maximal voluntary ventilation, the difference between normal subjects and patients disappeared. The reduced ventilatory response of these patients may be of mechanical origin and not depending on reduced CO2 sensitivity. The high lung volume of these patients may be the mean factor of the mechanical disadvantage of thoracomuscular system.

Simple parametrizations of maximum expiratory flow-volume curves.

Four elementary mono-compartmental lung models yield parametrizations of Maximal Expiratory Flow-Volume curves of normal subjects. The respective analytical functions are fitted to the measured curves and the mathematically derived ventilation indices are compared with standard measured data. While individual values of resistance and compliance seem devoid of a simple physical interpretation, their product indeed matches the models.

[Indications and limits in the use of digitalis in chronic cor pulmonale (author's transl)].

The analysis of the haemodymanic responses and the behaviour of many "contractility indices" of the right ventricle -- after acute intravenous injection of large doses of acetil-digoxin, in twelve patients with CPC caused by COLD with predominant clinical signs of emphysema (group A) or bronchitis (group B) -- showed an alarming, although transient, increase of the average pulmonary pressure (PAP), accompanied by rise of pulmonary arteriolar resistanced (RAP), especially in patients of the first group. In these cases a slow and cautious digitalization is required. It furthermore suggested that such treatment should start only after an efficient restoration of ventilation, in order to allow a good response of the heart to cardiocynetic treatment.
