“…This may be because the commercial nose-clips are too large for the children's noses. It should be noted that in our former study of the expiratory portion of the curve 14 we did not find a significant difference between the values obtained with or without a nose clip.…”

“…We found that the success rate of 73% for duplicate forced inspiratory maneuvers was close to the range found in forced expiratory curves. 14 The reproducibility of parameters of two curves was satisfactory. The number of healthy children who succeeded in performing the test was sufficient to calculate reference equations of the various inspiratory indices.…”

“…As opposed to the expiratory portion of the flow volume maneuver, the inspiratory shape of the curve did not vary with age. In our previous study, 14 we found that the expiratory curve varied with age: the descending part of the expiratory curve changed from a convex profile (round-shaped, peak flow-volume curve) at younger ages, to linear decay in older children. This phenomenon is also described in infants 30 and is thought to be a reflection of the developmental processes of lung maturation (lung volume/airway ratio).…”

Summary. Introduction: Spirometry testing should include both expiratory and inspiratory measurements. Inspiratory forced maneuvers can demonstrate extrathoracic airway abnormalities, of which various symptoms may suggest asthma. However, the inspiratory portion of the forced flow/volume maneuver in young healthy children has not yet been described. Objectives: To document and analyze the forced inspiratory flow volume curve indices in healthy young children. Settings and Participants: Healthy preschool children (age 2.5-6.5 years) from community kindergartens around Israel. Methods: The teaching method included multi-target, interactive spirometry games and accessory games for inspiration (e.g., inspiratory whistle). Results: One hundred and fourteen out of a total of 157 children performed duplicate full adequate inspiratory maneuvers. Repeatability between two maneuvers was 5.6%, 4.0%, 5.1%, 7.3% for inspiratory capacity (IC), forced inspiratory vital capacity (FIVC), peak inspiratory flow (PIF), and mid inspiratory flow (FIF50). Inspiratory flow indices were significantly lower than the expiratory flow indices. The time to reach PIF was significantly longer (mean AE SD; 229 AE 21 msec) than the time to reach peak expiratory flow (92 AE 8 msec; P < 0.0001). The shape of the inspiratory curve was parabolic and did not vary with age. The formed predicted equations were in agreement with the extrapolated values for older healthy children. Conclusions: The majority of healthy young children can perform reliable maximum inspiratory flow volume curves. Our results provide a framework of reference equations for maximum inspiratory flow volume curve in the young children. The clinical applications of these equations have to be explored.

Forced expiratory maneuvers are routinely used in children, 6 years of age and older for the diagnosis and follow-up of respiratory diseases. Our objective was to establish normative data for an extensive number of parameters measured during forced spirometry in healthy 3- to 5-year-old children. Children aged between 3 and 5 years were tested in 11 daycare centers. Usual parameters, including FEV1, FVC, PEF, FEF(25-75), FEF25, FEF50, FEF75, and Aex were measured and analyzed in relation to sex, age, height, and weight. In addition, the same analysis was performed for FEV0.5 and FEV0.75. One hundred sixty-four children were recruited for testing including 87 girls and 77 boys. Thirty-five were 3 years old, 63 were 4 years old, and 66 were 5 years old. Overall, 143 children (87%) accepted to perform the test and 128 children (78%) were able to perform at least two technically acceptable expiratory maneuvers. Analyses using different regression models showed that height was the best predictor for every parameter. In conclusion, the present study confirms that most healthy 3-5 years old children can perform valid forced expiratory maneuvers. In agreement with other studies, we found that height is the most important single predictor of various parameters measured on forced spirometry. The present study is the first to establish normative values for FEV0.75, as well as to demonstrate that Aex can be easily performed in the majority of children aged 3-5 years. These are likely important parameters of lung function in this age range.
