Journal Article
Ellis, R., Laviola, M., Stolady, D., Valentine, R. L., Pillai, A., & Hardman, J. G. (2022). Comparison of apnoeic oxygen techniques in term pregnant subjects: a computational modelling study. British Journal of Anaesthesia, 129(4), 581-587. https://doi.org/10.1016/j.bja.2022.06.021

Background Hypoxaemia during general anaesthesia can cause harm. Apnoeic oxygenation extends safe apnoea time, reducing risk during airway management. We hypothesised that low-flow nasal oxygenation (LFNO) would extend safe apnoea time similarly to...

Background: Optimal respiratory support in early COVID-19 pneumonia is controversial and remains unclear. Using computational modelling, we examined whether lung injury might be exacerbated in early COVID-19 by assessing the impact of conventional ox...

Pre-hospital continuous positive airway pressure after blast lung injury and hypovolaemic shock: a modelling study (2021)
Journal Article

Background In non-traumatic respiratory failure, pre-hospital application of CPAP reduces the need for intubation. Primary blast lung injury (PBLI) accompanied by haemorrhagic shock is common after mass casualty incidents. We hypothesised that pre-h...

Annals of Intensive Care, 11(1), Article 109. https://doi.org/10.1186/s13613-021-00904-7

Background: There is ongoing controversy regarding the potential for increased respiratory effort to generate patient self-inflicted lung injury (P-SILI) in spontaneously breathing patients with COVID-19 acute hypoxaemic respiratory failure. However,... Read More about High risk of patient self-inflicted lung injury in COVID-19 with frequently encountered spontaneous breathing patterns: a computational modelling study.

Ventilation strategies for front of neck airway rescue: an in silico study (2021)
Journal Article

Background. During induction of general anaesthesia a “can’t intubate, can’t oxygenate” (CICO) situation can arise, leading to severe hypoxaemia. Evidence is scarce to guide ventilation strategies for small-bore front of neck airways that ensure effe...
