title: [Indirect evaluation of respiratory muscle strength with the help of markers of maximal inspiratory and expiratory pressure in the mouth of healthy individuals].
abstract: The aim of the study was the evaluation of respiratory muscle strength by measurement of maximal inspiratory (PImax) and expiratory (PEmax) pressures values. Results for 166 clinically normal subjects (79 female and 87 male) were obtained. The results were as follow: in woman PImax ranged 38-104 cm H2O, average 60 cm H2O, PEmax ranged 46-140 cm H2O average 87.5 cm H2O, in men PImax was 40-120 cm H2O, average 73.2 cm H2O, PEmax ranged 46-140 cm H2O, average 115.9 cm H2O. PImax was negatively correlated with age in both groups. There was no correlation between age and PImax or PEmax in both groups (p > 0.05). There was no correlation between PImax and PEmax and height in women group and men group treated apart. The correlation was found between PImax as well as PEmax and height for whole group (p = 0.00019). There were observed positive correlation between PImax, PEmax and weight in both (male and female) groups. The comparison of results of present study with those obtained in former studies reveals important differences of norms for different populations. The normal values of maximal inspiratory and expiratory pressures in the mouth (PImax, PEmax) should be qualified individually for studied population. The normal values recommended by producers of medical equipment might be inadequate for studied population.
