“…To evaluate the breathing pattern and thoracoabdominal motion, respiratory inductive plethysmography was used (Respitrace ® , Nims, Miami, FL, USA). This is a noninvasive method that requires little exertion by the participant; it has been shown to be accurate [22][23][24] and has been used in previous studies 3,5,7,[10][11][12][14][15][16][17][25][26][27][28][29][30][31][32] . Respiratory inductive plethysmography measurements are based on changes to the cross-sectional area detected by two inductance bands.…”

“…In relation to thoracoabdominal motion, the following were analyzed: rib cage motion (%RC); phase angle (PhaseAng), which reflected the delay between rib cage and abdomen excursions 4,5,12,14,15,27 ,29,30 ; inspiratory phase relation (PhRIB) and expiratory phase relation (PhREB), which reflected the percentage of time during one breath in which the rib cage and abdomen moved in opposite directions, respectively 29,30 .…”

Objective: To describe the breathing pattern and thoracoabdominal motion of healthy individuals, taking age and sex into consideration. Methods:The study included 104 individuals aged 20 to 39, 40 to 59, and 60 to 80 years (41 males and 63 females), with normal body mass index and spirometric values. Participants were evaluated at rest in the supine position, by means of respiratory inductive plethysmography. The following variables were measured: tidal volume (Vt), respiratory frequency (f), minute ventilation (VE), inspiratory duty cycle (Ti/Ttot), mean inspiratory flow (Vt/Ti), rib cage motion (%RC), inspiratory phase relation (PhRIB), expiratory phase relation (PhREB), and phase angle (PhaseAng). Comparisons between the age groups were performed using one-way ANOVA or KruskalWallis H, while comparisons between the sexes were performed using Student's t test or the Mann-Whitney U test, depending on the data distribution; p<0.05 was taken to be significant. Results: Comparison between the sexes showed that, in the age groups 20 to 39 and 60 to 80 years, women presented significantly lower values for Vt, VE, and Ti/Ttot than men, and there was no significant difference in the age group 40 to 59 years. Comparisons between the age groups showed that participants aged 60 to 80 presented significantly greater PhRIB and PhaseAng than participants aged 20 to 39 years, without significant differences in the breathing pattern. Conclusion:The data suggest that breathing pattern is influenced by sex whereas thoracoabdominal motion is influenced by age.Key words: respiratory physical therapy; assessment; breathing pattern; thoracoabdominal motion; healthy individuals.

“…Em outras palavras, os autores consideraram que os sinais respiratórios tinham padrão sinusoidal para aplicação dessa técnica. Desta forma, o método do ângulo de fase é baseado numa técnica de análise de sinais elétricos [48][49], subentendendo que os sinais dos compartimentos toracoabdominais sejam sinusoidais [7][8]36], embora na realidade os sinais de origem biológica como os sinais respiratórios da estrutura toracoabdominal sempre oscilam em um ritmo diferente daqueles estudados na engenharia elétrica [7,14,36,45].…”

“…O outro método mais encontrado na revisão da literatura foi o de relação de fase [3,36,[44][45][46], que independe da forma dos sinais [7,22,36,45]. A relação de fase consiste em determinar a razão de tempo em que os sinais de dois compartimentos se deslocam em direções opostas com relação ao ciclo respiratório.…”

“…No entanto, neste estudo, o método foi expresso em graus (º), assim como o método do ângulo de fase, para criar variáveis equivalentes e facilitar a comparação entre ambos. O valor em porcentagem foi transformado para uma escala de 0 a 180 graus utilizando-se uma regra de três [45] (ver equações na Figura 7).…”

Aim: To study the most effective body position for Heimlich maneuver. Methods: A choking simulation manikin was connected to a laryngeal model of a child or an adult, and a differential pressure transducer recorded the airway pressure and waveform during the maneuver. A konjac jelly was placed on the larynx to mimic complete supralaryngeal obstruction. The maneuver (five successive compressions) was carried out six times each in standing, prone, and supine positions. For cases of children, we added a supine position with a pillow under the back.Results: In the adult model, airway obstruction was more frequently relieved in the supine and prone positions than in the standing position (P < 0.001). In the child model, airway obstruction was more frequently relieved in the supine position, with a pillow, and in the prone position, than in the standing position (P < 0.001). Without relief, successive Heimlich maneuvers made the airway pressure increasingly negative (adult, from À21.9 AE 6.5 cmH 2 O to À31.5 AE 9.1 cmH 2 O in the standing position [P < 0.001]; child, from À15.0 AE 9.5 cmH 2 O to À30.0 AE 9. Conclusions: The Heimlich maneuver was more effective in the supine and prone positions. In children, the prone position may be most effective. Successive Heimlich maneuvers may be harmful when the airway is not relieved after the first compression.
