Snippet: A possible way of allowing DPV for patients with different characteristics -particularly different tidal volume requirements and/or different lung compliance -is to alter the impedance (i.e. resistance or compliance) of the breathing loop to which they are connected, in order to share the delivered tidal volume more appropriately. Increasing the resistance in the inspiration tube for the patient with the higher lung compliance or requiring a lowe.....
Document: A possible way of allowing DPV for patients with different characteristics -particularly different tidal volume requirements and/or different lung compliance -is to alter the impedance (i.e. resistance or compliance) of the breathing loop to which they are connected, in order to share the delivered tidal volume more appropriately. Increasing the resistance in the inspiration tube for the patient with the higher lung compliance or requiring a lower tidal volume seems plausible. This is the subject of this paper. A team from Hospital Geel, Belgium, have been experimenting with the same technique [2], and a simulation study has been published from a group in (mostly) London, UK, in the last few days (SolÃs-Lemus et al, 2020) . This latter paper succinctly reviews previous work on DPV and the challenges involved.
