Reply to Grocott HP, regarding their comment on 'Jet insufflator for cannot intubate cannot ventilate situation: An Indian Jugaad'

摘要

We thank Dr. Grocott for the insightful comments regarding our frugal innovation of jet insufflator for cannot intubate cannot ventilate situation.[1]Dr. Grocott suggests that the new commercially available device, the Ventrain.(Ventinova Medical B. V., Eindhoven, The Netherlands) exploits the Hagen–Poiseuille law for both jet inspiration as well as active expiration. The Hagen–Poiseuille law comments on the flow characteristics of a fluid or gas. The active expiration occurring in Ventrain is according to Bernoulli's theorem.[2]Our device provides the possibility of expiration as a passive process, which is not available with jet ventilators like Manujet III.The availability of devices such as Ventrain, Rapid O2, Enk oxygen flow modulator and Manujet III is still limited in India.
