Optimal technique for Deep Breathing exercises after cardiac surgery
Minerva anestesiologica, 2015Co-Authors: Elisabeth WesterdahlAbstract:Cardiac surgery patients often develop a restrictive pulmonary impairment and gas exchange abnormalities in the early postoperative period. Chest physiotherapy is routinely prescribed in order to reduce or prevent these complications. Besides early mobilization, positioning and shoulder girdle exercises, various Breathing exercises have been implemented as a major component of postoperative care. A variety of Deep Breathing maneuvres are recommended to the spontaneously Breathing patient to reduce atelectasis and to improve lung function in the early postoperative period. Different Breathing exercises are recommended in different parts of the world, and there is no consensus about the most effective Breathing technique after cardiac surgery. Arbitrary instructions are given, and recommendations on performance and duration vary between hospitals. Deep Breathing exercises are a major part of this therapy, but scientific evidence for the efficacy has been lacking until recently, and there is a lack of trials describing how postoperative Breathing exercises actually should be performed. The purpose of this review is to provide a brief overview of postoperative Breathing exercises for patients undergoing cardiac surgery via sternotomy, and to discuss and suggest an optimal technique for the performance of Deep Breathing exercises.

the immediate effects of Deep Breathing exercises on atelectasis and oxygenation after cardiac surgery
Scandinavian Cardiovascular Journal, 2003Co-Authors: Elisabeth Westerdahl, Tomas Eriksson, Birgitta Lindmark, Goran Hedenstierna, Arne TenlingAbstract:Objective—To investigate the effects of Deep Breathing performed on the second postoperative day after coronary artery bypass graft surgery. Design—The immediate effects of 30 Deep breaths performed without a mechanical device (n = 21), with a blow bottle device (n = 20) and with an inspiratory resistance‐positive expiratory pressure mask (n = 20) were studied. Spiral computed tomography and arterial blood gas analyses were performed immediately before and after the intervention. Results—Deep Breathing caused a significant decrease in atelectatic area from 12.3 ± 7.3% to 10.2 ± 6.7% (p < 0.0001) of total lung area 1 cm above the diaphragm and from 3.9 ± 3.5% to 3.3 ± 3.1% (p < 0.05) 5 cm above the diaphragm. No difference between the Breathing techniques was found. The aerated lung area increased by 5% (p < 0.001). The PaO 2 increased by 0.2 kPa (p < 0.05), while PaCO 2 was unchanged in the three groups. Conclusion—A significant decrease of atelectatic area, increase in aerated lung area and a small incre...

chest physiotherapy after coronary artery bypass graft surgery a comparison of three different Deep Breathing techniques
Journal of Rehabilitation Medicine, 2001Co-Authors: Elisabeth Westerdahl, Birgitta Lindmark, Stigolof Almgren, Arne TenlingAbstract:The effectiveness of three Deep Breathing techniques was evaluated in 98 male patients after coronary artery bypass graft surgery in a randomized trial. The techniques examined were Deep Breathing with a blow bottle-device, an inspiratory resistance-positive expiratory pressure mask (IR-PEP) and performed with no mechanical device. Pulmonary function and roentgenological changes were evaluated. Four days post-operatively there were signie cantly decreased vital capacity, inspiratory capacity, forced expiratory volume in 1 second, functional residual capacity, total lung capacity and single-breath carbon monoxide diffusing capacity in all three groups ( p < 0.0001). No major differences between the treatment groups were found, but the impairment in pulmonary function tended to be less marked using the blow bottle technique. The Blow bottle group had signie cantly less reduction in total lung capacity (p = 0.01) compared to the Deep Breathing group, while the IR-PEP group did not signie cantly differ from the other two groups.

preliminary study comparative effects of lung volume therapy between slow and fast Deep Breathing techniques on pulmonary function respiratory muscle strength oxidative stress cytokines 6 minute walking distance and quality of life in persons with copd
International Journal of Chronic Obstructive Pulmonary Disease, 2018Co-Authors: Jirakrit Leelarungrayub, Rungthip Puntumetakul, Thanyaluck Sriboonreung, Yothin Pothasak, Jakkrit KlaphajoneAbstract:Background Lung volume therapy with the Voldyne® device can improve lung volume and has a nonsignificant benefit on respiratory muscle strength via the slow Deep-Breathing technique (SDBT); whereas respiratory muscle training with a respiratory muscle trainer via the fast Deep-Breathing technique (FDBT) has produced a significant improvement in people with COPD. Thus, the aim of this study was to compare the efficiency of lung volume therapy with the Voldyne® device with the SDBT and FDBT on pulmonary function, respiratory muscle strength, oxidative stress, cytokines, walking capacity, and quality of life (QoL) in people with COPD. Methods A total of 30 COPD patient volunteers with mild (stage I) to moderate (stage II) severity were randomized into two groups: SDBT (n=15) and FDBT (n=15). Pulmonary function (FVC, FEV1, and FEV1/FVC), maximal inspiratory mouth pressure (PImax), oxidative stress status (total antioxidant capacity [TAC], glutathione [GSH], malondialdehyde [MDA], and nitric oxide [NO]), inflammatory cytokines (tumor necrosis factor-alpha [TNF-α] and IL-6), 6-minute walking distance (6MWD), and total clinical COPD questionnaire (CCQ) score were evaluated before and after 4 weeks of training. Results All the parameters had no statistical difference between the groups before training. The PImax, TAC, IL-6, total QoL score, and 6MWD changed significantly in the SDBT group after the 4-week experiment as compared to those in the pre-experimental period, whereas FVC, FEV1, FEV1%, FEV1/FVC%, PImax, TAC, MDA, NO, TNF-α, IL-6, 6MWD, and total CCQ score changed significantly in the FDBT group as compared to those in the pre-experimental period. The FEV1%, PImax, TNF-α, IL-6, and total CCQ score differed significantly in the FDBT group in the post-experimental period as compared to those in the SDBT group. Conclusion This preliminary study concluded that the application of incentive spirometry with the Voldyne® device via fast Deep Breathing possibly improved respiratory muscle strength and QoL and reduced inflammatory cytokines, MDA, and NO better than that via slow Deep Breathing among people with COPD.

effect of slow Deep Breathing on visceral pain perception and its underlying psychophysiological mechanisms
Neurogastroenterology and Motility, 2021Co-Authors: Ali Gholamrezaei, Ilse Van Diest, Ans Pauwels, Jan Tack, Johan W S Vlaeyen, Lukas Van OudenhoveAbstract:BACKGROUND Studies using somatic pain models have shown the hypoalgesic effects of slow, Deep Breathing. We evaluated the effect of slow, Deep Breathing on visceral pain and explored putative mediating mechanisms including autonomic and emotional responses. METHODS Fifty-seven healthy volunteers (36 females, mean age = 22.0 years) performed controlled, Deep Breathing at a slow frequency (6 breaths per minute), controlled Breathing at a normal frequency (14 breaths per minute; active control), and uncontrolled Breathing (no-treatment control) in randomized order. Moderate painful stimuli were given during each condition by delivering electrical stimulation in the distal esophagus. Participants rated pain intensity after each stimulation. Heart rate variability and self-reported arousal were measured during each condition. KEY RESULTS Compared to uncontrolled Breathing, pain intensity was lower during slow, Deep Breathing (Cohen's d = 0.40) and normal controlled Breathing (d = 0.47), but not different between slow, Deep Breathing and normal controlled Breathing. Arousal was lower (d = 0.53, 0.55) and heart rate variability was higher (d = 0.70, 0.86) during slow, Deep Breathing compared to the two control conditions. The effect of slow, Deep Breathing on pain was not mediated by alterations in heart rate variability or arousal but was moderated by pain catastrophizing. CONCLUSIONS AND INFERENCES Slow, Deep Breathing can reduce visceral pain intensity. However, the effect is not specific to the slow Breathing frequency and is not mediated by autonomic or emotional responses, suggesting other underlying mechanisms (notably distraction). Whether a long-term practice of slow, Deep Breathing can influence (clinical) visceral pain warrants to be investigated.

respiratory hypoalgesia the effect of slow Deep Breathing on electrocutaneous thermal and mechanical pain
The Journal of Pain, 2020Co-Authors: Imke Courtois, Ali Gholamrezaei, Ilse Van Diest, Johan W S Vlaeyen, Lukas Van Oudenhove, Hassan Jafari, Stefan LautenbacherAbstract:Abstract The aim of the study reported in this paper is to investigate the effect of slow-Deep Breathing (SDB) on self-reported pain, heart rate variability, and baroreflex sensitivity (BRS). These effects are examined in 3 separate experiments, each using a different phasic pain modality. For each experiment, different subjects were recruited. Eighty-three healthy female participants were instructed to breathe guided by a visual cue at a slow frequency (SDB: .1 Hz), and at a frequency close to the spontaneous Breathing frequency (normal paced Breathing, .2 Hz). Pain was induced during instructed Breathing using electrocutaneous (experiment 1, n = 31), thermal (experiment 2, n = 28), or mechanical stimuli (experiment 3, n = 24). Participants were requested to rate the intensity of each painful stimulus (Numerical Rating Scale) and subjective level of pleasantness, arousal, and dominance (self-assessment manikin). During the experiment, R-R interval, blood pressure, tidal volume, and end-tidal CO2 were continuously measured. Results for self-reported pain, self-assessment manikin, and physiological measurements were consistent across the 3 experiments. Although SDB significantly increased baroreflex sensitivity and heart rate variability, self-reported pain did not differ between Breathing conditions, regardless of pain modality. Other potential mechanisms or components should be considered such as behavioral modulators including relaxation and treatment expectation. Perspective Merely slowing down the Breathing frequency to .1 Hz is not sufficient to induce hypoalgesia, despite the significant physiological effects associated with SDB compared to spontaneous Breathing.

can slow Deep Breathing reduce pain an experimental study exploring mechanisms
The Journal of Pain, 2020Co-Authors: Ali Gholamrezaei, Johan W S Vlaeyen, Lukas Van Oudenhove, Hassan Jafari, Mathijs Franssen, Qasim Aziz, Omer Van Den Bergh, Ilse Van DiestAbstract:Abstract Slow Deep Breathing (SDB) is commonly employed in the management of pain, but the underlying mechanisms remain equivocal. This study sought to investigate effects of instructed Breathing patterns on experimental heat pain and to explore possible mechanisms of action. In a within-subject experimental design, healthy volunteers (n = 48) performed 4 Breathing patterns: 1) unpaced Breathing, 2) paced Breathing (PB) at the participant's spontaneous Breathing frequency, 3) SDB at 6 breaths per minute with a high inspiration/expiration ratio (SDB-H), and 4) SDB at 6 breaths per minute with a low inspiration/expiration ratio (SDB-L). During presentation of each Breathing pattern, participants received painful heat stimuli of 3 different temperatures and rated each stimulus on pain intensity. Respiration, heart rate, and blood pressure were recorded. Compared to unpaced Breathing, participants reported less intense pain during each of the 3 instructed Breathing patterns. Among the instructed Breathing patterns, pain did not differ between PB and SDB-H, and SDB-L attenuated pain more than the PB and SDB-H patterns. The latter effect was paralleled by greater blood pressure variability and baroreflex effectiveness index during SDB-L. Cardiovascular changes did not mediate the observed effects of Breathing patterns on pain. Perspectives SDB is more efficacious to attenuate pain when Breathing is paced at a slow rhythm with an expiration that is long relative to inspiration, but the underlying mechanisms remain to be elucidated.

The PImax, TAC, IL-6, total QoL score, and 6MWD changed significantly in the SDBT group after the 4-week experiment as compared to those in the pre-experimental period, whereas FVC, FEV1, FEV1%, FEV1/FVC%, PImax, TAC, MDA, NO, TNF-α, IL-6, 6MWD, and total CCQ score changed significantly in the FDBT group as compared to those in the pre-experimental period. The FEV1%, PImax, TNF-α, IL-6, and total CCQ score differed significantly in the FDBT group in the post-experimental period as compared to those in the SDBT group. Conclusion This preliminary study concluded that the application of incentive spirometry with the Voldyne® device via fast Deep Breathing possibly improved respiratory muscle strength and QoL and reduced inflammatory cytokines, MDA, and NO better than that via slow Deep Breathing among people with COPD.
