“…In many reports, authors show that suitable position changing affected oxygenation of blood increased gas stimulation, prevent decubitus ulcers and reduce urinary stasis (3). There are many studies showing that suitable position changing affects oxygenation of the blood and increases gas exchange in patients with cardiac or respiratory system problems (4,5,6,7,8,9,10). Proper positioning may promote oxygenation in a less traumatic, less invasive and less expensive manner than high-tech treatment such as intubation (11).…”

Objective: This study was planned to determine the effects of different position changes on hemodynamic parameters and dyspnea severity in patients with dyspnea. Methods: This was a quasi-experimental study, using a one-group, pre-test and posttest design. From March-December, 2015, 58 pulmonary service patients who had been hospitalized due to dyspnea and various respiratory diseases were assessed for dyspnea severity, oxygen saturation (SpO 2 ), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and respiratory rate (RR). Results: According to repeated measures variance analysis of patients in the prone and orthopnea position, there was no statistically significant difference between the measurement of dyspnea severity, O 2 saturation, SBP, DBP, and RR. However, the HR of patients increased in the prone position and dyspnea severity was shown to be reduced in the orthopnea position. Conclusion: Comparing all the positions given to the patients, it was found that towards the 15 th minutes, the orthopnea position had a positive effect on patients' mean dyspnea severity, SBP and O 2 saturation but a significant difference was observed only on the mean dyspnea severity. ÖZAmaç: Dispnesi olan hastalarda pozisyon değişiminin yaşamsal bulgular, oksijen saturasyonu ve dispne şiddeti üzerine etkisini belirlemek amaçlanmıştır. Matreryal Metot: Bu araştırma ön test ve son test tasarımı kullanılan yarı deneysel bir çalışmadır. Mart-Aralık 2015 tarihleri arasında göğüs hastalıkları servisinde dispne ve çeşitli solunum hastalıkları nedeniyle yatarak tedavi gören 58 hastanın dispne şiddeti, oksijen saturasyonu (SpO 2 ), sistolik kan basıncı, diyastolik kan basıncı, kalp hızı ve solunum hızı değerlendirilmiştir. Bulgular: Tekrarlayan varyans analizi sonuçlarına göre hastaların prone ve ortopne pozisyonunda dispne şiddeti, O 2 saturasyonu, sistolik kan basıncı, diyastolik kan basıncı ve solunum hızı istatistiksel olarak anlamlı farklılık göstermemiştir. Fakat hastaların kalp hızı prone pozisyonunda artış göstermiş ve dispne şiddeti ise ortopne pozisyonunda azalmıştır. Sonuç: Hastalara verilen tüm pozisyonlar karşılaştırıldığında, ortopne pozisyonunun 15. dakikasında hastaların ortalama dispne şiddeti, sistolik kan basıncı ve O 2 satürasyonunda pozitif bir etki olduğu fakat sadece ortalama dispne şiddetinde anlamlı bir fark olduğu saptanmıştır. Anahtar Kelimeler: Pozisyon değişimi, dispne algısı, hemodinamik parametreler, prone pozisyonu, ortopne pozisyonu

“…Breathing patterns during the arm bracing posture were not significantly different in previous studies as well. 10,24 From these results, the cause of decreased dyspnea with the arm bracing position may not be a change in breathing pattern (except for end-inspiratory lung volume, end-expiratory lung volume, and EFL), metabolic demand, and the improvement of hypoxia according to the change of posture but may instead be a decrease of EFL.…”

“…Therefore, as the hands or forearms are stabilized, the sternum, clavicle, and rib cage can be pulled upward by the scalene, sternocleidomastoid, and pectoralis major muscles. 9,10 As a result, we considered the possibility that dyspnea decreased because the inspiratory accessory muscles can work more effectively as respiratory muscles. Also, this mechanism is supported by the study of Cavalheri et al, 25 which showed that the arm bracing posture increased respiratory muscle strength.…”

“…Mechanisms to relieve dyspnea through arm bracing have been reported to increase the activity of respiratory accessory muscles and decrease the work of breathing by taking the load off of the thorax. 6,9,10 The arm bracing posture also increases lung volume. 11,12 No study has investigated whether it is possible to decrease EFL by decreasing airway resistance by bracing the arms, because airway resistance depends on lung volume.…”

Effects of Arm Bracing on Expiratory Flow Limitation and Lung Volume in Elderly COPD Subjects

et al. 2015

BACKGROUND: Although it is useful for COPD patients to relieve their dyspnea by bracing their arms, the relationships between the arm bracing posture and expiratory flow limitation (EFL) and lung volume are unknown. Whether arm bracing affects dyspnea, EFL, and lung volume in elderly COPD patients was investigated. METHODS: Sixteen elderly subjects (median [interquartile range] age 81 [77-85] y) with stable COPD (percent-of-predicted FEV 1 50.9 [31.3-64.9] %) and 16 agematched healthy subjects were studied. Breathing patterns, EFL, lung volume, S pO 2 , and heart rate during quiet breathing were randomly evaluated in 3 standing postures: erect, leaning forward, and arm bracing. Dyspnea was also assessed for each posture with a Borg dyspnea score at the end of the test. RESULTS: Lung volume was significantly higher with arm bracing than with the other postures in both groups (P < .05). Breathing patterns, S pO 2 , and pulse rate were not significantly different among the 3 postures in both groups. However, EFL and Borg dyspnea scores were significantly lower with arm bracing than with the other postures in COPD subjects (P < .01). CONCLUSIONS: The decreased EFL in the arm bracing position may be caused by breathing at a higher lung volume than in the erect position, which may be one of the factors relieving dyspnea in elderly COPD patients.

“…This posture is associated with a decreased lumbar lordosis, resuling in lengthening of erector spinae. So, the distance between xiphisternum and pubic symphysis is reduced resulting in shortening of abdominal muscles [34]. This approximation of ribs to the pelvis results in increased intra-abdominal pressure and makes difficult for the diaphragm to descend caudally during inspiration [35].…”

Background: Numerous studies in COPD have shown that deconditioning is a major contributory factor resulting in the reduced strength and endurance. However, most of the studies have assessed upper extremity and lower extremity strength. Upper extremity and lower extremity strength and endurance exercises are the mainstay of Pulmonary rehabilitation programme. However, core muscles strength assessment and strengthening are not included in pulmonary rehabilitation programme. Hence, there is a need to assess the strength of core muscles in COPD patients. Materials and Methods:This Cross sectional comparative observational study included 70 participants (35 COPD patients + 35 Healthy matched individuals). Patients with COPD and age, gender and BMI matched healthy individuals are recruited in study after taking their consent to participate in the study. Core muscle strength will be measured by Stabilizer's pressure biofeedback unit, with the help of Richardson and Jull's core muscle grading method. Wilcoxon signed rank test (non parametric test for paired sample) was used for the comparison of core muscle strength between study group and control group (Age, gender and BMI matched healthy individuals) At 95% Confidence interval, level of significance was 0.05.Results: There was a reduction in core muscle strength in Study group as compared to the control group which was statistically not significant, (p=0.105). Odds ratio of core muscle strength, showed the risk of having reduced core muscle strength in study group (COPD) was 5.66 times greater than that of control group (Matched healthy individuals). Conclusion:There is no statistically significant difference in the strength of the core muscles in patients with COPD as compared to the age, gender and BMI matched healthy individuals. However, odds ratio shows reduced strength of core muscle in COPD patients. It has moderate association with functional capacity and weak association with degree of obstruction and BMI in patients with COPD.
