INFLUENCE OF THE EXPIRATORY PRESSURE LEVELS ON THE ALVEOLAR RECRUITMENT OF THE HEALTHY SUBJECTS.
Few studies have analyzed the effect of different well-defined PEP levels on lung function since the majority of clinical trials use PEP mask and a pressure «fork».

The objective of this study is to find out if there is a common level of PEP to be applied which allows optimization of alveolar recruitment, objectivity by tomography by electric impedance, for all subjects. The study was carried out on 14 healthy participants, 7 men and 7 women, aged 22 to 30. Participants had a exhale against four resistors of different values, determined by the tension of the spring, 5, 10, 15 and 20cmH20. The measurement of alveolar recruitment during the experiment was carried out by an electrical impedance tomograph. Each participant reacted differently to the PEP levels, but by comparing the responses of the pulmonary function, it is noted that the individual characteristics can influence the alveolar recruitment, whatever the level of resistance applied. It would be interesting to investigate, on a larger sample and with several groups of participants with low inter-individual variability, whether there is a correlation between individual characteristics and the potential for alveolar recruitment. This would optimize care by adapting it to each subject. Există puține studii care au analizat efectul diferitelor niveluri de presiune expiratorie pozitivă (PEP) bine definite asupra funcției pulmonare, deoarece majoritatea studiilor clinice utilizează mască PEP şi o „furcă" de presiune. Obiectivul acestui studiu este de a afla dacă există un nivel comun de PEP care trebuie aplicat, care permite optimizarea recrutării alveolare, relevate prin tomografie de impedanță electrică, pentru toți subiecții. Studiul a fost realizat pe 14 participanți sănătoşi, 7 bărbați şi 7 femei, cu vârste cuprinse între 22 şi 30 de ani. Participanții au expirat împotriva a patru rezistențe de valori diferite, determinate de tensiunea arcului, 5, 10, 15 şi 20cmH20. Măsurarea recrutării alveolare în timpul experimentului a fost efectuată de un tomograf de impedanță electrică. Fiecare participant a reacționat diferit la nivelurile PEP, dar prin compararea răspunsurilor funcției pulmonare, se observă că recrutarea alveolară poate fi influențată de caracteristicile individuale, indiferent de nivelul de rezistență aplicat. Ar fi interesant de investigat, pe un eşantion mai mare şi cu mai multe grupuri de participanți cu variabilitate interindividuală scăzută, dacă există o corelație între caracteristicile individuale şi potențialul de recrutare alveolară. Acest lucru ar optimiza tratamentul prin individualizarea lui la fiecare subiect. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
