A novel smartphone app for blood pressure measurement: a proof-of-concept study against an arterial catheter
Hofmann, Gregory; Proença, Martin; Degott, Jean; Bonnier, Guillaume; Lemkaddem, Alia; Lemay, Mathieu; Schorer, Raoul; Christen, Urvan; Knebel, Jean-François; Schoettker, Patrick (2022-06-21)Smartphones may provide a highly available access to simplified hypertension screening in environments with limited health care resources. Most studies involving smartphone blood pressure (BP) apps have focused on validation ... -
Accuracy of blood pressure measurement across BMI categories using the OptiBP™ mobile application
Caillat, Mary; Degott, Jean; Wuerzner, Arlene; Proença, Martin; Bonnier, Guillaume; Knebel, Jean-François; Stoll, Chloé; Christen, Urvan; Durgnat, Virginie; Hofmann, Gregory; Burnier, Michel; Wuerzner, Grégoire; Schoettker, Patrick (2022-12-31) -
Automated Pulse Oximeter Waveform Analysis to Track Changes in Blood Pressure During Anesthesia Induction: A Proof-of-Concept Study
Ghamri, Yassine; Proença, Martin; Hofmann, Gregory; Renevey, Philippe; Bonnier, Guillaume; Braun, Fabian; Axis, Alexandre; Lemay, Mathieu; Schoettker, Patrick (2020)BACKGROUND: Intraoperative hypotension is associated with postoperative complications and death. Oscillometric brachial cuffs are used to measure arterial pressure (AP) in most surgical patients but may miss acute changes ... -
Blood pressure measurements with the OptiBP smartphone app validated against reference auscultatory measurements
Schoettker, Patrick; Degott, Jean; Hofmann, Gregory; Proença, Martin; Bonnier, Guillaume; Lemkaddem, Alia; Lemay, Mathieu; Schorer, Raoul; Christen, Urvan; Knebel, Jean-François; Wuerzner, Arlene; Burnier, Michel; Wuerzner, Gregoire (2020-10-20)Mobile health diagnostics have been shown to be effective and scalable for chronic disease detection and management. By maximizing the smartphones’ optics and computational power, they could allow assessment of physiological ... -
Blood Pressure Monitoring Using a Smartphone Camera: Performance of the OBPM Technology
Sola, Josep; Proenca, Martin; Schoettker, Patrick; Lemkaddem, Alia; Braun, Fabian; Verjus, Christophe; Bertschi, Mattia; Kunz, Thierry (2018)While hypertension globally affects two out of five adults worldwide, there exists no easily-scalable technology to measure blood pressure out of the clinics. The idea of using smartphone sensors to estimate blood pressure ... -
Continuous non-invasive monitoring of blood pressure in the operating room: a cuffless optical technology at the fingertip
Solà, Josep; Proença, Martin; Braun, Fabian; Pierrel, Nicolas; Degiorgis, Yan; Verjus, Christophe; Lemay, Mathieu; Bertschi, Mattia; Schoettker, Patrick (2016-09-01)Abstract Routine monitoring of blood pressure during general anaesthesia relies on intermittent measurements with a non-invasive brachial cuff every five minutes. This manuscript provides first experimental ... -

Photoplethysmography-Based Blood Pressure Monitoring Could Improve Patient Outcome during Anesthesia Induction
Degiorgis, Yan; Proença, Martin; Ghamri, Yassine; Hofmann, Gregory; Lemay, Mathieu; Schoettker, Patrick (2022-10)During anesthesia, noncritical patients are routinely monitored via noninvasive cuff-based blood pressure (BP) monitors. Due to the noncontinuous nature of the monitoring, the BP values of the patient remain unavailable ... -
