Comparison of apnoeic oxygen techniques in term pregnant subjects: a computational modelling study (2022)
Journal Article

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...

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...

Effect of variable pre-oxygenation endpoints on safe apnoea time using high flow nasal oxygen for women in labour: a modelling investigation (2021)
Journal Article

Background Studies of pulmonary denitrogenation (pre-oxygenation) in obstetric populations have shown high flow nasal oxygen therapy (HFNO) is inferior to facemask techniques. HFNO achieves median end-tidal oxygen fraction (FE′O2) of 0.87 after 3...

In Silico Modeling of Coronavirus Disease 2019 Acute Respiratory Distress Syndrome: Pathophysiologic Insights and Potential Management Implications (2020)
Journal Article

Objectives: Patients with COVID-19 Acute Respiratory Distress Syndrome (CARDS) appear to present with at least two distinct phenotypes: severe hypoxemia with relatively well-preserved lung compliance and lung gas volumes (Type 1) and a more conventio...

Effect of oxygen fraction on airway rescue: a computational modelling study (2020)
Journal Article

© 2020 British Journal of Anaesthesia Background: During induction of general anaesthesia, patients frequently experience apnoea, which can lead to dangerous hypoxaemia. An obstructed upper airway can impede attempts to provide ventilation. Although... Read More about Effect of oxygen fraction on airway rescue: a computational modelling study.

Mathematical and Computational Modelling in Critical Illness (2019)
Journal Article

Mathematical and computational modelling are assuming a prominent role in investigating the complex pathophysiological states and therapeutic strategies in critical illness. This editorial briefly illustrates the models of the respiratory and cardiov... Read More about Mathematical and Computational Modelling in Critical Illness.

High oxygen fraction during airway opening is key to effective airway rescue in obese subjects (2019)
Conference Proceeding

Apnea is common after induction of anesthesia and may produce dangerous hypoxemia, particularly in obese subjects. Optimal management of airway emergencies in obese, apneic subjects is complex and controversial, and clinical studies of rescue strateg...

Computer simulation clarifies mechanisms of carbon dioxide clearance during apnoea (2018)
Journal Article

Background Apnoeic oxygenation can come close to matching the oxygen demands of the apnoeic patient but does not facilitate carbon dioxide (CO2) elimination, potentially resulting in dangerous hypercapnia. Numerous studies have shown that high-flo... Read More about Computer simulation clarifies mechanisms of carbon dioxide clearance during apnoea.

Assessment of diaphragmatic thickness by ultrasonography in Duchenne muscular dystrophy (DMD) patients (2018)
Journal Article

Introduction In Duchenne muscular dystrophy (DMD) the assessment of diaphragmatic function is crucial because respiratory muscle weakness can cause respiratory failure. We aimed to noninvasively assess diaphragmatic function in DMD by measuring diap...

Investigating the effect of cardiac oscillations and deadspace gas mixing during apnea using computer simulation (2017)
Conference Proceeding

Gaseous mixing in the anatomical deadspace with stimulation of respiratory ventilation through cardiogenic oscillations is an important physiological mechanism at the onset of apnea, which has been credited with various beneficial effects, e.g. reduc...
