Abstract
There is a high clinical demand to measure pulmonary artery pressure (PAP). However, existing solutions are either highly invasive or only allow for intermittent measurements by a trained clinician. Research at CSEM during the last years has revealed a potential alternative to measure PAP by means of electrical impedance tomography (EIT). Being low-cost and safe, EIT allows for the fully noninvasive and continuous measurement of PAP. This was first evaluated in a study on healthy volunteers, confirming its potential. More recently, these findings were corroborated in a second study on neonatal lambs where EIT-derived measurements were compared to the invasive gold-standard PAP reference over a large range of pressure values. These promising results pave the way towards a novel way of PAP measurement in clinical settings.
