“…Clinically, MIP is the most common technique in the assessment of inspiratory muscle strength, and MEP is the only test generally available for measuring expiratory muscle strength [ 20 ]. The portable spirometer used in this study is accurate and reliable when compared to formal laboratory-based spirometry [ 23 ]. The results, however, are highly dependent on subject motivation, and there might be leaks around the mouth during the performance, especially at higher pressures and in older subjects [ 20 ].…”

ObjectiveTo evaluate sarcopenic indices in relation to respiratory muscle strength (RMS) in elderly people.MethodsThis study included 65 volunteers over the age of 60 (30 men and 35 women). The skeletal muscle mass index (SMI) was measured using bioimpedance analysis. Limb muscle function was assessed by handgrip strength (HGS), the Short Physical Performance Battery (SPPB), and gait speed. RMS was addressed by maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) using a spirometer. The relationships between RMS and other sarcopenic indices were investigated using the Pearson correlation coefficients and multiple regression analysis adjusted for age, HGS, and SPPB.ResultsBoth MIP and MEP were positively correlated with SMI (r=0.451 and r=0.388, respectively, p<0.05 in both). HGS showed a significant correlation with both MIP and MEP (r=0.560, p<0.01 and r=0.393, p<0.05, respectively). There was no significant correlation between gait speed and either MIP or MEP. The SPPB was positively correlated with MEP (r=0.436, p<0.05). In the multiple regression analysis, MIP was significantly associated with HGS and SMI (p<0.001 and p<0.05, respectively), while MEP was related only with HGS (p<0.05).ConclusionThis study suggests that respiratory muscles, especially inspiratory muscles, are significantly related to limb muscle strength and skeletal muscle mass. The clinical significance of MIP and MEP should be further investigated with prospective studies.

“…In Western countries, the portable spirometer has demonstrated consistency that is similar to that of traditional pulmonary function equipment in the determination of various parameters. [9][10][11][12][13] However, scant evidence exists in relation to the reliability of portable spirometry for evaluation of Chinese patients. 14 In this study, we sought to validate the agreement of measurements obtained with portable versus traditional spirometers in a Chinese cohort.…”

BACKGROUND: In this study, we aimed to validate the agreement between pulmonary function measurements obtained with a portable spirometer and measurements obtained with conventional spirometry in Chinese pediatric and adult populations. METHODS: Pulmonary function testing was performed to evaluate subjects enrolled at Shanghai Zhongshan Hospital (n 5 104) and Shanghai Children's Medical Center (n 5 103). The portable spirometers and conventional devices were applied to each subject with a 20-min quiescent period between each measurement. Pulmonary function parameters of FVC, FEV 1 , peak expiratory flow, maximum expiratory flow at 25%, 50%, and 75% of FVC (MEF 25 , MEF 50 , and MEF 75 , respectively), and FEV 1 /FVC% were compared with intraclass correlation and Bland-Altman methods. RESULTS: A satisfactory concordance of pulmonary function was observed between spirometry measurements obtained with portable versus conventional spirometers. Intraclass correlation indicated excellent reliability (>0.75) for all pulmonary function indicators in pediatric and adult subjects. Significant positive correlations of all variables measured with different spirometers were observed (all P < .001). No significant bias was observed in either group, although limits of agreement varied. Funnel effects were observed for peak expiratory flow in pediatric subjects and for FVC, FEV 1 , MEF 50 , and MEF 25 in adult subjects. CONCLUSIONS: The portable spirometer is an alternative to the conventional device for the measurement of pulmonary function.

“…high-risk patients. Although the previous study had shown significant correlation between OS and LS for both forced FEV1 and FVC in patients with COPD (20), it should be also noted that there are patients at high-risk for pulmonary complications even if the spirometry data does not show low FEV1/FVC (8,23). Moreover, it is also great interests of pulmonary physicians whether both FEV1 and FVC of OS show significant association with those of LS in patients with a variety of pathologies.…”

“…For these reasons, some researchers have investigated potential clinical relevance of office-based spirometry (OS) that can be easily performed in outpatient office with less cost and time (19). Previous investigations demonstrated that OS parameters including expiratory volume in one second (FEV1) and forced vital capacity (FVC) had been significantly correlated with LS parameters (20) and OS was reportedly useful for screening of chronic obstructive pulmonary disease (COPD) (21). In a recent paper of Hudson et al in the Annals of Thoracic Surgery (22), the authors demonstrated that patients who had undergone preoperative OS had experienced similar major morbidity to those who had undergone preoperative LS after propensity score matching.…”
