Prolonged extracorporeal membrane oxygenation use as a bridge to lung transplantation: it is time for a national registry.

Abstract

Correspondence Although we cited reference 30 (cited here as reference 2) under Subjects in the Materials and Methods section, it might have been better to also cite it under Estimation of Sleep Duration in the Materials and Methods section. Altogether, we believed that the use of the actigraph along with the diary for the purpose of the two studies would be superior to the use of only a sleep diary. As Dr Kawada mentioned, sleep duration was a key factor in this study, 1 and the participants wore the actigraph for 7 days so we could measure the mean daily sleep duration. An actigraph (Actiwatch AW-Light; Mini Mitter or Koninklijke Philips Electronics NV) has been used in many reports. We believed that the use of the actigraph as described here was suitable for this study. We appreciate the comments of Dr Kawada. They enabled us to provide details of our method for calculating sleep duration that were only briefl y provided in our article. 1
