Comments on the study by Taniguchi and coworkers – proving Hippocrates is alive

First paragraph (this article has no abstract)

I read with interest the article by Taniguchi and coworkers [1] and its accompanying commentary by Adigüzel and colleagues [2] in Critical Care. I have some questions concerning the methodology of the study. Taniguchi and coworkers randomized the postoperative patients to two groups: automated pressure support (PS) mandatory rate ventilation (MRV) and manual PS. In the automated PS MRV group, the patient's expected respiratory rate (RR) was used as a guide to adjust the PS level, employing the algorithm of the Taema-Horus Ventilator^® (Air Liquid, France) in MRV mode. However, in the manual PS group the guide for adjusting the PS level was tidal volume/RR (which was kept less than 80 l), and adjustments were done manually every 30 minutes by intensive care staff.
