Пиковая скорость выдоха и бронхиальное сопротивление у пациентов с внебольничной пневмонией

Пиковая скорость выдоха и бронхиальное сопротивление у пациентов с внебольничной пневмонией

Abstract

52 community-acquired pneumonia (CAP) patients were monitored peakflowmetrically with peak expiratory flow examination results analysis and correlation with bronchial resistance (Raw) identified by the method of bodyplethismography. When brought to hospital, 88,5% CAP patients had PEF below individual due value (IDV), which amounted to 59,27±2,16% IDV on average. Raw was registered within the due values (0,22±0,01 kPa·sec/l) even in the cases of an abrupt PEF decrease. The CAP patients' PEF decrease could not be the evidence of bronchial blockade, because there was no simultaneous Raw increase registered. PEF decrease during the acute CAP period must have been caused by extrapulmonary factors (general weakness, respiratory muscle weakness) resulting from intoxication.

У 52 пациентов внебольничной пневмонией (ВП) проведен пикфлоуметрический мониторинг с анализом результатов пиковой скорости выдоха (ПСВ) и сопоставлением их с бронхиальным сопротивлением (Raw), определенным бодиплетизмографически. У 88,5% больных ВП при поступлении в стационар ПСВ находилась ниже индивидуальных должных величин (ИДВ), в среднем 59,27±2,16% ИДВ. Raw регистрировалось в пределах значений должных величин (0,22±0,01 кПа·сек/л) даже в случаях резкого снижения ПСВ. Снижение ПСВ у больных ВП не могло свидетельствовать о нарушении бронхиальной проходимости, поскольку одновременного повышения Raw зарегистрировано не было. Снижение ПСВ в остром периоде ВП, вероятно, было обусловлено внелегочными факторами: слабостью дыхательной мускулатуры и интоксикацией.
