“…SNIP has a strong correlation with MIP; however, it usually is higher than MIP 37 . SNIP is considered a highly reproducible, volitional, easy to perform maneuver in children starting at the age of 6 years, with normative data, 37,38 where in the occluded nostril, the nasal pressure is obtained after forced inspiration from FRC 39 . There are notable limitations to the accuracy of SNIP in populations with severe obstructive disease or severe neuromuscular disease.…”

Progressive neuromuscular disease leads to muscle weakness or failure that produces loss of pulmonary function and clinical respiratory morbidity. Tracking pulmonary function in a practical and effective way is very important because it can help identify a stage of disease when a morbidity, such as inadequate airway clearance or respiratory failure, may be present. There are four general categories of pulmonary function outcome measures such as volume, flow, pressure, and gas exchange. These outcome measures have variable precision and accuracy in predicting clinical change, and practicality in performing them relative to age and condition. It is widely recommended to follow multiple measurements longitudinally and create an accurate and timely clinical picture. This manuscript will review the most commonly used and most practical measures for use in clinical practice and how they can help to assess morbidity, disease state, and help optimize patient management.

“…All children were asked to place the plug in the nostril, through which air passed more freely, and to perform a short, sharp inspiratory effort through the nostril, in the sitting position and with the lips closed 2 . This maneuver was performed near functional residual capacity, and a passive relaxation immediately after reaching the peak pressure was requested 11,19 . All children performed 12 maneuvers, with a 30 s rest between each.…”

Background Sniff nasal inspiratory pressure (SNIP) is a voluntary inspiratory maneuver measured through a plug occluding one nostril. The investigation of the number of maneuvers necessary to reach the highest peak of SNIP in pediatric populations has been inconsistent. Thus, our goal was to assess the reliability SNIP in healthy children aged 6 to 11 years and compare with regard to sex and age group, as well as to determine the adequate number of maneuvers. Methods This cross-sectional study included healthy children with normal pulmonary function. Were performed 12 to 20 maneuvers SNIP near functional residual capacity, with a 30 s rest between each. Reliability was tested using intraclass correlation coefficient (ICC), standard error of measurement (SEM), minimal detectable change (MDC), and Bland-Altman analysis for agreement. Results A total of 121 children (62 girls [51%]) were included. The ICC and corresponding confidence interval (CI) between the highest measure and the first reproducible maneuver was 0.752 (0.656–0.824), SEM of 10.37 cmH2O and MDC of 28.74 cmH2O. For children aged 6–7 and 8–11 years, the ICC (CI) was 0.669 (0.427–0.822), SEM = 10.76 cmH2O and MDC = 29.82 cmH2O, and 0.774 (0.662–0.852), with SEM = 9.74 cmH2O and MDC = 26.05 cmH2O, respectively. For girls, the ICC (CI) was 0.817 (0.706–0.889), SEM = 9.40 cmH2O and MDC = 26.05 cmH2O; for boys, 0.671 (0.487–0.798), SEM = 11.51 cmH2O and MDC = 31.90 cmH2O. Approximately 80% of the total sample reached the highest SNIP before the 10th maneuver. Conclusions SNIP demonstrated moderate reliability between the maneuvers in children aged 6 to 11 years. Otherwise, older children and girls reached the SNIP peak faster. Finally, results suggested that 12 maneuvers were sufficient for healthy children aged 6 to 11 years to achieve the highest SNIP peak.

“…SNIP involves a short sharp, voluntary inspiratory maneuver measured through a plug occluding one nostril while the sniff is performed using the contralateral nostril 5,11 . Because there is a signi cant learning effect on the performance of SNIP, several maneuvers are required, with a plateau usually reached after 5 to 10 measurements in adults 4 .…”
