摘要:

Summary112 subjects, constituting a “non‐pulmonary” group, and 16 subjects, 9 males and 7 females, constituting an “atypical” pneumonia group, were investigated at various time in the course following the acute phase of the actual infection with series of cardiopulmonary function tests. The “non‐pulmonary” group consisted of convalescents after infectious diseases with no involvement of the lungs. In the “atypical” pneumonia group, most cases had suffered from “primary atypical pneumonia” with lesions in the lungs probably of interstitial pneumonitis type. The x‐ray picture was normalized or almost normalized at the time for investigation.2The rate of work at a pulse rate of 170/min. (W170) was in the “non‐pulmonary” group normal or almost normal. W170in the “atypical” pneumonia group was in relation to heart volume somewhat low. Slight to moderate orthostatic reactions as well at rest in standing as during work in sitting were a little more frequent in the “atypical” pneumonia group.3The pulmonary function was in the “non‐pulmonary” group as a whole in close agreement with earlier normal materials.4The static lung volumes in the “atypical” pneumonia group were slightly reduced and certain distrurbances in the mechanics of breathing could not be excluded.Alveolar ventilation was normal in most cases. The diffusion capacity of the lungs was reduced at rest and during exercise as well in absolute terms as in relation to BSA and mid‐capacity.Anatomical shunts ranging from 6 to 15 % of cardiac output were found. The lung function was not impaired to such a degree

摘要:

SummaryPulmonary diffusion capacity (DLCO), membrane diffusion capacity (DM) and pulmonary capillary blood volume (VC) have been studied in 8 subjects at various times in the course following the acute phase of “atypical” pneumonia. The x‐ray picture was, at the time of investigation, in most cases normalized or almost normalized.Alveolar ventilationand distribution of inspired gas was within normal limits in all cases.Anatomical shuntsranging from 4 to 22 per cent of cardiac output were found.The membrane diffusion capacity(DM) was decreased in most cases, both in absolute terms and in relation to the mid‐capacity of the lungs.The capillary blood volume(VC) was found to vary considerably, being either normal or

摘要:

Summary9 subjects, 3 males and 6 females, were investigated in the course following “atypical” penumonia with a series of cardio‐pulmonary function tests at two occasions with an average time interval of 23 weeks. The first investigation was in eight cases carried out a few days or weeks after end of the acute infectious phase when the x‐ray picture was almost or entirely normalized and in one cases after 12 months.The rate of work performed at a pulse rate of 170 beats/min. (W170) was found to have increased considerably in relation to heart volume. The heart volume was not significantly different from, although lower than a normal material at the first investigation and in fairly close agreement with this normal material at the second one. Moderate orthostatic pulse reactions were found in some cases at the first investigation, but were almost absent six months later.The static lung volumes were found to be somewhat low at the first, but within normal limits at the second investigation.Alveolar ventilation was within normal limits at both investigations.Nitrogen wash‐out index was likewise found to be within normal limits at both investigations, although somewhat higher at the first test occasion in some cases.The diffusion capacity for carbon monoxide was shown to be somewhat low in relation to predicted normal value at both investigations at rest and during exercise as well in absolute terms as in relation to midcapacity, indicating that the membrane diffusion capacity was more or less affected.The anatomical shunts, which were higher than normal in all cases at the first investigation, were found to have decreased considerably in all cases but two.Oxygen transport during exercise was at the first investigation in some cases mainly limited by circulatory factors alone or in combination with diffusion disturbances and/or venous admixture due to anatomical shunt. At the second investigation about six months later these factors were hardly of a magnitude as to have a limiting effect on oxygen transport during exercise although, in most cases, still not n
