This study investigated the effect of noseclips on spirometric measurements in patients with a range of disease. Fifty-two patients (30 male; mean age 58.0 years, range 19-78; mean FEV\n                    <jats:sub>1<\/jats:sub>\n                    82.6% predicted, range 23.8-128.3%) performed measurements of VC, FVC and FEV\n                    <jats:sub>1<\/jats:sub>\n                    according to ARTP\/BTS guidelines (1994) using a wedge bellows spirometer (Vitalograph Model S, Bucks, UK). All patients performed two sets of measurements (with and without noseclips) in random order (Group 1 = noseclips first; n = 30; Group 2 (without noseclips first, n = 22). Tests were conducted by qualified physiologists. Measurements obtained with and without the use of noseclips were similar (mean differences FEV\n                    <jats:sub>1<\/jats:sub>\n                    -0.030 L SD 0.210 and -0.005 L SD 0.093 for Groups 1 and 2 respectively; FVC -0.007 L SD 0.109 and -0.040 L SD 0.117; VC 0.036 L SD 0.137 and -0.040 L SD 0.150) and were not dependent on patient group or previous test experience. Four patients had differences outside the 95% confidence limits for each parameter. There were no significant correlations between the differences with and without noseclips and severity of lung disease, age, smoking history, BMI or lung volume (all P &gt; 0.100). The within patient coefficient of variation did not depend on the testing method. Use of noseclips during spirometry does not systematically affect the results obtained or the within-subject repeatability. Marked individual differences highlight the importance of maintaining consistency in the method adopted for a particular patient.\n                  <\/jats:p>","DOI":"10.1177\/1479972306072889","type":"journal-article","created":{"date-parts":[[2007,2,6]],"date-time":"2007-02-06T07:48:31Z","timestamp":1170748111000},"page":"53-57","source":"Crossref","is-referenced-by-count":11,"title":["Is it necessary to use a noseclip in the performance of spirometry using a wedge bellows device?"],"prefix":"10.1177","volume":"4","author":[{"given":"C","family":"Newall","sequence":"first","affiliation":[{"name":"PAREXEL International, Northwick Park Hospital, Harrow, UK,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T M","family":"McCauley","sequence":"additional","affiliation":[{"name":"Lung Investigation Unit, University Hospital Birmingham Foundation Trust, Birmingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Shakespeare","sequence":"additional","affiliation":[{"name":"Department of Respiratory Physiology, University Hospital Coventry and Warwickshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B G","family":"Cooper","sequence":"additional","affiliation":[{"name":"Lung Investigation Unit, University Hospital Birmingham Foundation Trust, Birmingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2007,2,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.152.3.7663792"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1016\/S0954-6111(05)80346-4"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.05.00034805"},{"key":"atypb4","first-page":"29","volume":"31","author":"Verrall AB","year":"1989","journal-title":"J Occup Med"},{"key":"atypb5","unstructured":"Gilson JC, Hugh-Jones P.
