The inspiratory muscles can expand even more, which allows the diaphragm to continue contracting downwards, thus increasing lung volumes [46]. Compared with the standing position, the effect of gravity on abdominal viscera is less at sitting position and least if lying supine . In sitting, the diaphragm is restricted on intake capacity. Interpretative strategies for lung function tests. A total of 43 studies fully met inclusion criteria and were included in the review (Fig. [Tests of overall respiratory function: recent advances (1999-2004)]. Thus, in the majority of studies the more upright position was associated with increased FVC. The overall mean closing-capacity-to-FRC ratio in the supine and 30° Fowl-er’s positions were very similar, with mean closing-capac-ity-to-FRC ratio lower in the sitting position (see Table 2). According to ATS/ERS guidelines, PFTs may be performed either in the sitting or standing position, and the position should be recorded on the report. This influences the ability of the lungs to expand laterally but allows the diaphragm to descend and the lungs to expand inferiorly. 2005;98(2):512–7. Agostoni PG, Cattadori G, Guazzi M, Palermo P, Bussotti M, Marenzi G. Cardiomegaly as a possible cause of lung dysfunction in patients with heart failure. Among subjects with asthma, CHF, and obesity no statistically significant difference in FEV1/FVC was found between the different body postures [18, 27, 32, 42]. 2001;57(2):357–9. Level of evidence was assessed according to the American Academy of Neurology (AAN) Classification of Evidence for therapeutic intervention [14]. The authors attributed the difference in responses to variations in pulmonary circulation pressures. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. The actual relationship between standing height and vital capacity is due to not only to developmental genes but also to an individual’s diet and environment during the developmental period. Meysman M, Vincken W. Effect of body posture on spirometric values and upper airway obstruction indices derived from the flow-volume loop in young nonobese subjects. Methods: A search to identify English-language papers published from 1/1998-12/2017 was conducted using MEDLINE and Google Scholar with key words: body position, lung function, lung mechanics, lung volume, position change, positioning, posture, pulmonary function testing, sitting, standing, supine, ventilation, and ventilatory change. California Privacy Statement, Two researchers (SK., E-LM.) 2010;11(1–2):194–202. Hurtado & Fray [1933] found slight de- creases in vital capacity in the supine position. The change in DLCO was probably related to the change in alveolar blood volume, most likely due to differences in pulmonary artery pressure and heart dimensions [58]. J Adv Med Pharma Sci. This can be explained by several mechanisms. Seven studies compared FEV1/FVC for different body positions in healthy subjects [18, 19, 23, 24, 27, 28, 42]. Accessed 29 May 2018. In addition, the details of the intervention protocol were not clearly reported in some studies (Table 1) and due to the nature of the study assessors could not be blinded to patient position or outcomes from previous tests. Cookies policy. 2006;33(1):127–32. Keenan SP, Alexander D, Road JD, Ryan CF, Oger J, Wilcox PG. 2017;21(3):7–12. The position on orthostasis showed higher values of vital capacity regarding standing (mean change: 0.15 ± 0.03 L; p = 0.001), the supine to 45 (average difference: 0.32 ± 0.04 L; p = 0.001) and 0° (0.50 ± 0.05 L; p = 0.001). Townsend (1984) found slightly higher FEV1 and FVC values in standing subject than in sitting posture. 2011. http://tools.aan.com/globals/axon/assets/9023.pdf. 2015;101(2):239–41. Neurology. Epub 2016 Jan 1. PEF in different body positions was evaluated in 13 studies [3, 22,23,24, 31, 33, 45,46,47,48,49,50,51]. In some patients diffusion capacity improved in the sitting position and others showed no change or a decline. Accessed 29 May 2018. Studies assessing lung function using other criteria and those without statistical comparisons of lung function in different positions, those enrolling individuals < 18 years or on mechanical ventilation, published conference abstracts, and systematic reviews were excluded. Among those with obesity, FEV1 was higher in sitting vs. supine both before and after bariatric surgery [41]. Physiother Theory Pract. Wanger J, Clausen JL, Coates A, et al. Wade OL, Gilson JC. Cardiology. Respiration. These effects might have negative impact on diffusion capacity, opposing the positive effect of the increase in blood volume in the alveoli [57]. 2002;14(1):1–5. McCoy EK, Thomas JL, Sowell RS, et al. However, among patients with CHF, no difference in FRC between sitting and supine was reported [27]. Supine fall in lung volumes in the assessment of diaphragmatic weakness in neuromuscular disorders. Secondary data were collected from the medical records of each patient. The COPD sitting position is more accurate since it flattens the diaphragm, allowing more air to come in. Chest. Shikma Katz and Nissim Arish contributed equally to this work. Risk of bias was assessed as moderate in 41 studies and low in two. 2015;60(7):992–9. Vital capacity is diminished when lying on one’s back as the weight of the anterior wall of the thorax impairs expansion of the thorax, and the weight of the anterior abdominal will and abdominal viscera impair contraction of the diaphragm. Standing and sitting have been shown to lead to the highest lung volumes [72, 73]. Only 7/43 studies reported sample size calculations required to reach statistical power. One study [39] found that VC was higher in the sitting vs. supine position. Another group [37] reported no significant change in FEV1 between the sitting and supine positions for a pooled group of patients with SCI, but in the subgroup of patients with incomplete motor injury and in those with incomplete thoracic motor injury there was a decrease in the supine position.

One study [18] found DLCO to be higher in the sitting vs. supine positions while another study found no difference in DLCO between these positions [21]. standing position, and still lower in the recumbent po-sition. Leaning over squeezes your lungs, making them smaller, and decreasing your breathing volume. In patients with cervical SCI (tetraplegia), FVC and FEV1 increase in the supine vs. sitting position. Chest measurements were made by Livingstone [1928] who used radio- logical methods; he demonstrated that the capacity ofthe chest is least when Eur Respir J. 1980;61(6):347–56. As cardiac dimension increases, lung volume, mechanical function, and diffusion capacity decrease [61, 62]; thus, the heart weighs on the diaphragm while sitting and on one of the lungs while in a side-lying position. However, other studies [21, 24, 28, 40] did not find significant difference for FEV1 between sitting and supine, RSL, and LSL. De S. Comparison of spirometric values in sitting versus standing position among patients with obstructive lung function. When treating patients with heart, lung, SCI, neuromuscular disease, or obesity, one should take into consideration that pulmonary physiology and function are influenced by body position. 2014;193:43–51. 1971;3(4):141–50. In lung disease, particularly restrictive lung disease, the amount of air the lungs can hold can be dramatically increased, this causing vital capacity … Tsubaki A, Deguchi S, Yoneda Y. Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation.It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume.It is approximately equal to Forced Vital Capacity (FVC). J Phys Ther Sci. When performing pulmonary function tests, body position plays a role in its influence over test results. Spirometric values in sitting, standing, and supine position. BMC Pulm Med 18, 159 (2018). Article  Among healthy subjects, two studies [24, 56] found statistically and clinically significant improvement in DLCO in supine vs. sitting and one [57] found a trend towards increased DLCO in supine vs. sitting, however this difference did not reach statistical significance. (2004), reported that slumped posture significantly reduced the lung capacity, compared with that … Sitting is preferable for safety reasons to avoid falling due to syncope [2], and might also be more convenient because of the measurement devices and patient comfort. SK, E-LM, NA, AR, YZ contributed to data acquisition and analysis, and interpretation of the data.

Third, the back of the chair may limit thoracic expansion. Table S1. 2014. https://www.nhlbi.nih.gov/health-topics/study-quality-assessment-tools. This might be related to reduced FVC and alveolar damage in these patients. SK, E-LM, NA, AR, YZ critically reviewed and revised the manuscript for intellectual content. Diaphragmatic strength is negatively affected by the supine position, and intrathoracic blood volume is increased. Further research in this field is needed, including studies designed to evaluate lung function in a larger number of healthy participants as well as in individuals with a variety of medical conditions. Less oxygen means less energy. Martinez BP, Silva JR, Silva VS, Neto MG, Forgiarini Júnior LA. The three factors in body position changes have different strengths in changing lung capacities, body excise having the highest impact followed by body bending, then standing position. Manning F, Dean E, Ross J, Abboud RT. Terms and Conditions, First, while the kinematic analysis was performed in both sitting and supine position, the pulmonary function tests were performed in sitting position only. Peak nasal inspiratory flow and peak expiratory flow. Eur Respir J. 2016;54(2):160–3. Age may attenuate this increase [76]. Another study [18] found no significant difference in diffusion capacity between the sitting and the supine positions. Explaining the patient how to perform the test is key to get a good result. Seven studies evaluated the effect of body position on diffusion capacity; six included healthy subjects [18, 20, 21, 24, 56, 57], three included patients with CHF [18, 21, 58], and one included COPD patients [57].

Statistically significant differences in pulmonary function between the various body positions [3, 17,18,19,20,21,22,23,24,25,26,27,28, 30, 31, 33, 34, 37,38,39,40,41, 43,44,45,46,47,48, 50,51,52,53,54, 56]. Patient cooperation during lung function testing strongly influences results. Side-lying was reported to reduce DLCO in comparison to sitting in the third study [21]. Springer Nature. Eur J Appl Physiol. 1992;102(1):139–42. Lechtzin N, Wiener CM, Shade DM, Clawson L, Diette GB. However, we did not find a systematic review that integrates findings from studies involving non-mechanically ventilated adults to derive clinical implications for respiratory care and pulmonary function test (PFT) execution. Effect of body positions on lungs volume in asthmatic patients: a cross-sectinal study. PEmax was higher in standing vs. supine, in standing vs. sitting and RSL, in sitting vs. supine [54], and in sitting vs. supine and RSL [46]; however, the differences reported in those studies were not clinically significant. This may be related to changes in lung volumes with positions. Eur Respir J. 2016;52(1):36–47. Abdominal surgery; Capacidade vital forçada; Cirurgia abdominal; Complicações pós-operatórias; Forced vital capacity; Posicionamento do paciente; Positioning the patient; Postoperative complications. Indian J Allergy Asthma Immunol. In most studies involving healthy subjects or patients with lung, heart, neuromuscular disease, or obesity, FEV1, FVC, FRC, PEmax, PImax, and/or PEF values were higher in more erect positions. The study populations included healthy subjects (29 studies), lung disease (nine), heart disease (four), spinal cord injury (SCI, seven), neuromuscular diseases (three), and obesity (four). The effect of sitting, standing and supine position on ventilatory functions has not been well studied in healthy subjects. Changes in body position can affect several measurements of pulmonary function. http://www.iapsmupuk.org/journal/index.php/IJCH/article/view/108. In side-lying positions, the heart weighs on one lung, compressing both airways and lung parenchyma, reducing alveolar blood volume, and causing ventilation/ perfusion mismatch. Among asthmatic patients, FEV1 was higher in the standing vs. supine position, a statistically and clinically significant change; however, there was no significant difference between sitting vs. supine, RSL, and LSL positions [30]. 2000;140(5):e24.

In contrast, diffusion capacity, as assessed by DLCO, increases in the supine position in healthy subjects while the effect in CHF patients is thought to depend upon pulmonary circulation pressure. 2005;26(3):511–22. Effect of supine posture on respiratory mechanics in chronic left ventricular failure. In one study, FVC was reported 200 ml higher in sitting vs. RSL and LSL [21], and in the other two studies FVC was higher in sitting vs. supine by 350–400 ml, which has clinical significance [18, 27]. In patients with ALS, supine FVC is a test of diaphragmatic weakness [65] that predicts orthopnea [25] and prognosis for survival [66, 67]. Four studies included subjects with lung disease [29,30,31,32]. Chang SC, Chang HI, Liu SY, Shiao GM, Perng RP. In addition, the expiratory muscles are at a more optimal region of the length-tension curve and thus are capable of generating higher intrathoracic pressure, potentially generating higher expiratory pressures and pushing air through narrow airways at high speed, which results in higher PEmax, PEF, and FEV1. Most studies in this systematic review of 43 papers evaluating the effect of body position on pulmonary function found that pulmonary function improved with more erect posture in both healthy subjects and those with lung disease, heart disease, neuromuscular diseases, and obesity. doi: 10.7860/JCDR/2016/16164.7064. Palermo P, Cattadori G, Bussotti M, Apostolo A, Contini M, Agostoni P. Lateral decubitus position generates discomfort and worsens lung function in chronic heart failure. N Engl J Med. Among those with cervical SCI, FVC was higher in the supine vs. sitting position [17, 33, 34]. One study found that VC was higher in the sitting vs. supine position. Respir Med. Understanding the influence of body position can give healthcare professionals better knowledge of optimal positions for patients with different diseases. The effect of body position on vital capacity was evaluated in six studies of healthy subjects [21, 24, 28, 39, 43, 44]. This mechanism is especially important in patients for whom the diaphragm is the main muscle for breathing, since their intercostal and abdominal muscles are inactive due to SCI. Global initiative for asthma (GINA): Global strategy for asthma management and prevention (2018 update). However, another study [44] found that VC was higher in the supine vs. sitting position, but only in females. 2003;97(6):647–53. When standing, gravity pulls the mediastinal and abdominal structures down, creating more space in the thoracic cavity, which allows further expansion of the lungs and greater lung volumes [74]. Another study in asthmatic patients reported FEV1 to be higher in standing vs. sitting, supine, RSL, and LSL, and in sitting  vs. supine, RSL and LSL [31]. Clipboard, Search History, and several other advanced features are temporarily unavailable. The differences were not clinically significant. However, in patients with cervical SCI, as well as those with thoracic injury in one study [36], there was an increased FVC in the supine vs. sitting, while in those with thoracic or lumbar injury FVC was higher in the sitting position [37].

Spirometry in the supine position improves the detection of diaphragmatic weakness in patients with amyotrophic lateral sclerosis. J Appl Physiol. Since the venous return to the thorax increases in supine position, the vital capacity and the total lung capacity may decrease. hard for diaphragm to move down What happens … Epub 2014 Sep 28. Nevertheless, it is important to note that in these debilitated patients with SCI, even a small change in FVC is probably clinically significant. (2) Two or more body positions compared, including at least the sitting or standing position.

Although these are not interventional studies, strictly speaking, we have chosen to assess them as “before and after intervention,” wherein the posture/position change is the maneuver of interest. Effects of posture on postoperative pulmonary function. A summary of study characteristics, including the positions studied, outcome measures, and main results according to the study population, is shown in Table 2. Diaphragm is the major muscle of inspiration, responsible for some two-thirds of the vital capacity. Gianinis HH, Antunes BO, Passarelli RC, Souza HC, Gastaldi AC. This is a pity, as we know that a drop in vital capacity (VC), when a patient goes from sitting to supine position, is a sign of diaphragm paralysis. The review included only adult subjects and it is therefore not possible to generalize the results to children and adolescents. A cross-sectional study conducted between August 2008 and January 2009 in a hospital in Salvador/BA. 2005;40(5):385–91. The instrument used to measure vital capacity was analogic spirometer, the choice of the sequence of positions followed a random order obtained from the draw of the four positions. Effects of body positions on respiratory muscle activation during maximal inspiratory maneuvers. Three studies included subjects with congestive heart failure (CHF) [18, 21, 27]. On the average no statistically significant difference was found between the two positions. Valenza F, Froio S, Coppola S, Vagginelli F, Tiby A, Marenghi MC, Mozzi E, Roviaro GC, Gattinoni L. Minerva Anestesiol. The major findings were that forced expiratory volumes in one and in six seconds and forced vital capacity were significantly larger (p < 0.001) in the standing than in the sitting posture, with mean standing minus sitting differences ranging from +0.06 to +0.08 L for the 3 indexes. In most studies no difference was reported between sitting and supine [21, 24, 28, 43] or between sitting and RSL or LSL [21]. 2009;90(8):1414–7. J Appl Physiol. All authors reviewed the final version of the manuscript prior to submission and all accept responsibility for the integrity of the research process and findings. In patients with CHF, different patterns of the effect of posture on DLCO were observed [58]. Diffusing capacity of the lungs for carbon monoxide. Ventilatory changes following head-up tilt and standing in healthy subjects. Chest. (DOCX 63 kb), Table S2. independently and in consultation when questions arose. NLM In one study among all subjects with SCI, FEV1 was not significantly influenced by moving from sitting to supine [35], but patients with cervical injuries showed a tendency for increased FEV1 in the supine vs. sitting position while those with thoracic injuries tended towards increased FEV1 in the sitting position. Decreased FVC in more recumbent positions may reflect both increased thoracic blood volume due to gravitational facilitation of venous return, which is more important in patients with heart failure, as well as cephalic displacement of the diaphragm due to abdominal pressure in the recumbent positions, which is more important in obese subjects [59]. The authors wish to thank Shifra Fraifeld, a medical center-based medical writer and editor, for her editorial contribution during manuscript preparation. Studies that included subjects older than 60 years did not mention the cognitive function of participants, a factor that may influence patient cooperation. Many pedagogical accounts of breathing in brass players discuss the effect of different standing and sitting postures and though numerous opinions have been expressed about this (Frederiksen 1996; Gordon 1987; Snell 1988; Steenstrup 2004), none has so far been based on experimental evidence.It is often suggested that when standing, vital capacity is greater and breathing movements more …  |  The effects of different degrees of head-of-bed elevation on the respiratory pattern and drainage following thyroidectomy: a randomized controlled trial.

Forty-three studies met inclusion criteria. Ray and associates studied 43 … Background: Spirometry may be done either in sitting or standing position. Standing, sitting, supine, and right- and left-side lying positions were studied. The changes in body position can cause changes in lung function, and it is necessary to understand them, especially in the postoperative upper abdominal surgery, since these patients are susceptible to postoperative pulmonary complications. In healthy subjects, most studies showed an increase in DLCO in supine vs. sitting [24, 56, 57]. 2005;26(1):153–61.
