A modification to the Maquet Flow-i anaesthesia machine for ICU ventilation

Andrew J Robinson; William London; Lazslo Kotan; Warwick Downing

The presented 'proof of concept' Bridge device holds the potential to allow conversion of many Maquet Flow-i machines currently under-utilised for their primary purpose into Intensive Care ventilators. It may thus help bridge that period of time while more purpose-built Intensive Care ventilators are manufactured. Local manufacture is available to New Zealand and near markets from RAM3D, but the CAD file is made available and allows the reader to replicate the Bridge locally and investigate manufacture by local engineering firms. Choice of material will depend on local manufacturing capability and available materials. This innovation is CC-BY 4.0 licensed and the authors welcome collaboration and clinical exploration of the modification by the wider Anaesthetics, Intensive Care, and Engineering communities.
