THE FEASIBILITY OF USING AN INSTRUCTIONAL VIDEO WITH FLOW VOLUME LOOP IN 4 AND 5 YEAR OLD CHILDREN

Background: Pulmonary function testing (PFT) in children aged 3-6 years is not easily achieved. PFT is important in the diagnosis and early treatment of pulmonary disease. Verbal coaching alone during testing is not sufficient in this age-group due to their short attention span. An instructional video which was developed in the pulmonary lab at Arkansas Children's Hospital (ACH), is followed by instructions from an experienced respiratory therapist so that these pre-schoolers can perform the forced vital capacity maneuver. Our study evaluates the efficacy of this instructional video in addition to the verbal coaching. Our hypothesis is that the use of this instructional video will decrease the time to obtain an acceptable forced expiratory flow-volume (FEFV) curve in pre-school children.

Methods: The pilot study was approved by the University of Arkansas for Medical Sciences (UAMS) Internal Review Board (IRB). Twenty, 4 and 5-year olds, from the Child Enrichment Center at ACH were enrolled. These children have not previously performed spirometry. They were randomly assigned before testing, 10 per group, to watch either the 4.5-minute instructional video (Group A) or a 4.5-minute cartoon video unrelated to the testing procedure (Group B). The period from the time each child entered the testing room until completion of the last test was measured. Spirometry was performed using the Eaglet Raptor Plus 4.08vs software by Ferraris Respiratory. The FEFV curve acceptance criteria that are employed in the ACH pulmonary lab were used for the purpose of this study.

Results: We compared Group A versus B: Mean age, 4.67/4.83 years; boys, 7/6; those producing acceptable FEFV curves were 6/4 within an average time of 11.33/9.75 minutes, and the number of trials to the first acceptable FEFV maneuver was 3.7/5 (P > 0.05, unpaired t test).

Conclusion: The instructional video seems useful in preparing pre-school children to perform spirometry. A study of a larger population that includes white and black boys and girls is needed to confirm our findings.
