“…Conversely, nonuniformly distributed pressure on the rib cage, or different values of upper and lower rib cage compliance [18], might account for constant upper to lower rib cage uncoupling throughout exercise. Unlike paradoxical movements of the lower rib cage at rest [19], during arm exercise [4] or during whole body endurance exercise [20], the minimal or null RC distortion during phonatory tasks might be better explained by coordinated activity of the respiratory muscles [17]. …”

“…Whether physical characteristics or gender per se dictate the breathing patterns during phonation in these patients has yet to be defined. The hyperinflation of the rib cage and abdomen in tandem represents the mechanical constraints to volume displacement in these patients [4]. However, deflationary activity of the abdominal compartment might not be able to reduce constraints on chest wall expiratory volume displacement if the rib cage is being dynamically hyperinflated.…”

Background: Breathing pattern description and chest wall kinematics during phonation have not been studied in male and female patients with chronic obstructive pulmonary disease. Objectives: We used optoelectronic plethysmography to provide a quantitative description of breathing pattern and chest wall kinematics. Methods: Volumes of chest wall compartments (rib cage and abdomen) were assessed in 15 patients while reading aloud (R), singing (SI) and during high-effort whispering (HW). Results: Relative to quiet breathing, tidal volume and expiratory time increased while inspiratory time decreased. The expiratory flow decreased during R and SI, but was unchanged during HW. In males, the end-expiratory volume decreased as a result of a decreased volume of rib cage during R, SI and HW and due to a decreased volume of abdomen during HW. In females, a decrease in end-expiratory volume was accomplished by a decrease in abdominal volume during R and HW. During R, the chest wall end-expiratory volume of the last expiration in females was to the left of the maximal expiratory flow volume curve (MEFV), with still substantial expiratory reserve volume available. In contrast, during SI and HW in females and during all types of phonation in males, chest wall end-expiratory volume of the last expiration was well to the right of the MEFV curve and associated with respiratory discomfort. Gender had a greater importance than physical characteristics in determining more costal breathing in females than in males under all conditions studied. Conclusions: Phonation imposes more abdominal breathing pattern changes in males and costal changes in females. Expiratory flow encroaches upon the MEFV curve with higher phonatory efforts and respiratory discomfort.

Background: Optoelectronic plethysmography (OEP) is a non-invasive motion capture method to measure chest wall movements and estimate lung volumes. Objectives: To provide an overview of the clinical findings and research applications of OEP in the assessment of breathing mechanics across populations of healthy and diseased individuals. Methods: A bibliographic research was performed with the terms “opto-electronic plethysmography,” “optoelectronic plethysmography,” and “optoelectronic plethysmograph” in 50 digital library and bibliographic search databases resulting in the selection of 170 studies. Results: OEP has been extensively employed in studies looking at chest wall kinematics and volume changes in chest wall compartments in healthy subjects in relation to age, gender, weight, posture, and different physiological conditions. In infants, OEP has been demonstrated to be a tool to assess disease severity and the response to pharmacological interventions. In chronic obstructive pulmonary disease patients, OEP has been used to test if patients can dynamically hyperinflate or deflate their lungs during exercise. In neuromuscular patients, respiratory muscle strength and chest kinematics have been analyzed. A widespread application of OEP is in tailoring post-operative pulmonary rehabilitation as well as in monitoring volume increases and muscle contributions during exercise. Conclusions: OEP is an accurate and validated method of measuring lung volumes and chest wall movements. OEP is an appropriate alternative method to monitor and analyze respiratory patterns in children, adults, and patients with respiratory diseases. OEP may be used in the future to contribute to improvements in the therapeutic strategies for respiratory conditions.

“…Essa falta de consenso pode ser explicada por três motivos: Existem evidências que permitem sustentar esta hipótese. Primeiro, semelhante aos nossos resultados, outros estudos já mostraram que o paciente com DPOC frequentemente apresenta um deslocamento maior no abdome do que na caixa torácica [3,26]. Segundo, alguns autores indicam que o paciente com DPOC que apresenta assincronia frequentemente contrai os músculos abdominais durante a expiração [60] e o relaxamento desses músculos é feito de forma gradativa durante a inspiração [5].…”

“…A ATA está presente em pacientes portadores de DPOC [3,[22][23][24][25] e parece estar associada com uma piora na obstrução do fluxo aéreo [20], maior sensação de dispneia [20,26] e um rápido padrão de hiperinsuflação durante o exercício [20]; determinando uma desvantagem mecânica que aumenta o trabalho respiratório e contribui para a limitação ao exercício nesses pacientes [24]. [30,32].…”
