The association between iPFT results and acute COVID-19
respiratory symptoms
Of the sixteen included cases, 7 infants (44%) experienced respiratory
symptoms (cough and/or dyspnea) during their COVID-19 illness. There was
no association between the presence of respiratory symptoms during the
acute COVID-19 illness and iPFT results (p>0.05 for all
evaluated indices). The one infant who had postnatal acute COVID-19
related ARDS had normal iPFT results at 2.7 months of age
(V̇maxFRC=119%predicted, FEV0.5=98%predicted,
FVC=93%predicted and TLC=105% predicted).
