[Mechanics of breathing and contractility of myocardium of right ventricle in chronic bronchial obstruction (author's transl)].

The Reaction of the right ventricle on pulmonary hypertension in chronic bronchial obstruction is to be described. Limitation of myocardial contraction-capacity may be measured by - the index of contractility, - the tension-time-index of the right ventricle and - the tendency of systolic stain-pressure to reach diastolic pulmonary arterial pressure in time of maximal pressure-elevation-velocity.

[Basic-diagnostic-criterions of respiratory insufficiency--results of a community work of the working group "pathophysiology of breathing" (author's transl)].

11 laboratories of the working group "Pathophysiology of Breathing" cooperated with standardized methods to obtain generally admitted practical criterions for the definition of respiratory insufficiency. Function parameters of 2800 examined persons in different diagnostic groups were tested by manual statistical analysis and computed by data processing system. which were assessed with regard to their usefulness as criterions for respiratory insufficiency. The arterial O2-partial pressure proved to be the most crucial criterion of respiratory insufficiency permitting objective evidence of a manifest respiratory insufficiency by hypoxeamia under standard efforts with a bicycle-ergometer. The screening parameters of ventilation such as vital capacity and forced exspiratory volume are suitable as subjective rapid methods for a quantitative estimation of one type of respiratory insufficiency: the ventilation disturbance. Investigations, which were carried out with a higher apparatus expense like the estimation of residual volume, the functional residual capacity, and the arterial CO2-partial pressure permit the further differentiation of causes of the respiratory insufficiency and the separation between respiratory partial- and global insufficiency. The parameters of gas exchange: O2-consumption, respiratory quotient, and the screening parameter of cardiocirculation heart rate are not or only limited useful as criterions of respiratory insufficiency alone.

[Studies on the limitation of the body functional capacity by the pulmonary function in chronic bronchitic patients in the work process].

It is reported on first experiences (18 patients) with investigation of the breathing mechanism during ergometry for the quantification of the respiratory dyspnoea on exertion. The oesophagus-pressure-method is recommended as suitable method. The stopping of the load on account of dyspnoea in the number of patients which above all consisted of obstructive bronchitics was carried out at values for the total breathing capacity (Wtot) of 5 kpm/min and more.

[Spontaneous pneumothorax as an urgent internal problem].

92 cases of pneumothorax of the clinic for lung diseases Lostau and 35 cases from 9 county hospitals of the district Magdeburg were analysed. In the two groups a vast correspondence of the following data was found: average age of the patients (40.0 or 46.2 years), duration of stay in the ward (25.3/23.5 days), as urgent cases 11 or 8 patients, respectively, were hospitalised. Only in 5% of all cases a treatment on the conditions of an intensive therapy unit was necessary. Apart from the clinical and radiological basal diagnostics a measurement of the interpleural pressure by means of the pneumothorax apparatus is demanded. These values form the basis for a differentiated therapy of the pneumothorax: conservative attitude with sedation of cough of the patient in minimal pneumothoraces; withdrawal by means of the pneumothorax apparatus in more severe lung collapse, appearances of tension, lacking tendency to re-expansion of the lung after 3 days' conservative-medicamentous therapy; rubber-tube drainage when the withdrawal by means of the pneumothorax apparatus was ineffective for three times; surgical therapy when a 7 to 10 days' rubber-tube drainage was without success.
