Fig. 2From: Optimization of sniff nasal inspiratory pressure (SNIP) measurement methodology in healthy subjectsMean maximal SNIP (± SD) obtained using different nostril techniques (n = 51). RNLO: right nostril, left occluded; RNLNO: right nostril, left non-occluded; LNRO: left nostril, right occluded; LNRNO: left nostril, right non-occluded. * denotes significant differences (P < 0.01) between RNLO vs. RNLNO and LNRO vs. LNRNOBack to article page
