We thank the readers for their interest in our article [1]. Bhattacharya et al. have pointed out a few issues; most of these were already addressed in the article. Following are our responses to the points highlighted [2].We agree with Bhattacharya et al. that if ultrasound of the lung and diaphragm was done in a large number of severe cases, the observation would have become a more interesting one. But as we have mentioned in the limitations of the study in the article, no patient with severe bronchiolitis severity score at admission could be enrolled in the study.We do agree with the point that ultrasound is an operatordependent procedure, However, in our study, we did look for the interobserver correlation (kappa statistics) where we found a very good agreement between the pediatrician and the radiologist. We did follow a standard six-zone longitudinal scanning protocol, from apex to the base of the lungs for doing lung ultrasound as mentioned in the "Materials and Methods" section [3].As we have already mentioned in our article, we did not use any oral or intravenous sedation during the procedure. We were able to keep the babies calm during ultrasound examination by allowing breastfeed or by using a pacifier.Your point is well taken. Since it was not our primary or secondary objective, we did not study the correlation between arterial blood gases and POCUS to plan the treatment protocol. It can be planned for future studies.
