RC\u2014AB asynchrony was calculated by the phase angile (PA) technique and compared to normal values (0\u201324\u00b0) derived from a separate group of 45 control children, matched for age and weight. Eighty\u2010two of the 110 patients had PSG as part of their evaluation for obstructive sleep apnea. There was a high association between the phase angles and the PSG results (<jats:italic>P<\/jats:italic> &lt; 0.01; Fisher's exact test). PSG was abnormal in 38\/82 patients (46%) and the phase angle was increased in 51\/82 (62%) (mean \u00b1 SD, 68\u00b0 \u00b1 39\u00b0; range 28\u00b0\u2013168\u00b0) compared to the normal controls (<jats:italic>P<\/jats:italic> &lt; 0.001). Fourteen of the 110 patients had bronchopulmonary dysplasia; of these, PSG and PA results agreed in six normal and seven abnormal studies and disagreed in only one (<jats:italic>P<\/jats:italic> = 0.002). Six of 110 patients had Down's syndrome; 5 of 6 had increased RC\u2014AB asynchrony, compared to 3 of 6 who had abnormal PSG. Eight of 110 patients were evaluated for central apnea and hypoventilation; PA was abnormal in 4 of 8, who also had abnormal PSG and in 1 with normal PSG. We conclude that RC\u2014AB measurement by the PA technique may be an important adjunct to the evaluation of breathing disorders during sleep in small children and it may be a good screening test for small children who need PSG.<\/jats:p>","DOI":"10.1002\/ppul.1950110211","type":"journal-article","created":{"date-parts":[[2007,3,6]],"date-time":"2007-03-06T15:29:12Z","timestamp":1173194952000},"page":"141-146","source":"Crossref","is-referenced-by-count":22,"title":["Rib cage to abdominal asynchrony in children undergoing polygraphic sleep studies"],"prefix":"10.1002","volume":"11","author":[{"given":"Yakov","family":"Sivan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sally Davidson","family":"Ward","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy","family":"Deakers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas G.","family":"Keens","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher J.
