Unobtrusive pulse rate monitoring by continuous video recording, based on remote photoplethysmography (rPPG), might enable early detection of perioperative arrhythmias in general ward patients. However, the accuracy an rPPG-based machine learning model to monitor during sinus rhythm and is unknown. We conducted a prospective, observational diagnostic study cohort with high prevalence (patients undergoing elective electrical cardioversion). Pulse was assessed rPPG via visible light camera ECG...
Mechanical ventilation is a lifesaving treatment for critically ill patients in an Intensive Care Unit (ICU) or during surgery. However, one potential harm of mechanical related to patient-ventilator asynchrony (PVA). PVA can cause discomfort the patient, damage lungs, and increase length stay ICU on ventilator. Therefore, automated detection algorithms are being developed detect classify PVAs, with goal optimizing ventilation. development these often requires large labeled datasets;...
ObjectiveThe corrected left ventricular ejection time (cLVET) comprises the phase from aortic valve opening to closure for heart rate. As a surrogate measure cLVET, carotid flow (ccFT) has been proposed in previous research. The aim of this study was assess clinical agreement between cLVET and ccFT dynamic setting.MethodsTwenty-five patients with severe stenosis (AS) were selected transcatheter replacement (TAVR). derived outflow tract (LVOT) common artery (CCA), respectively, using pulsed...
We provide new insights into the performance of camera-based heart and respiration rate extraction evaluate its usability for replacing spot checks conducted in general ward. A study was performed comprising 36 ICU patients recorded a total time 699 h. The 5 beats/minute agreement between camera ECG-based measurements 81.5%, with coverage 81.9%, where largest gap 239 min. challenges encountered monitoring were limited visibility patient’s face irregular rates, which led to poor camera-...
Determining the optimal timing for extubation can be challenging in intensive care. In this study, we aim to identify predictors failure critically ill patients with COVID-19.We used highly granular data from 3464 adult COVID multicenter Dutch Data Warehouse, including demographics, clinical observations, medications, fluid balance, laboratory values, vital signs, and life support devices. All intubated at least one attempt were eligible analysis. Transferred patients, admitted less than 24...
To explore if change in the extent of emphysema correlated with lung function, effect resection emphysematous tissue was studied by computed tomography (CT) densitometry. In addition, current authors how surgery-induced related to density control subjects. total, 30 patients (14 females; mean± sd age 59±10 yrs) severe before and 3 months after volume reduction surgery (LVRS), 48 moderate 76 subjects were investigated. Lung (15th percentile point) both lungs heterogeneity between 12...
Uncalibrated arterial waveform analysis enables dynamic preload assessment in a minimally invasive fashion. Evidence about the validity of technique patients with impaired left ventricular function is scarce, while adequate cardiac would be great value these patients. The aim this study was to investigate diagnostic accuracy stroke volume variation (SVV) measured FloTrac/Vigileo™ system function. In prospective, observational study, 22 ejection fraction 40 % or less undergoing elective...
Background and objectives Currently, no evidence-based criteria exist for decision making in the post anesthesia care unit (PACU). This could be valuable allocation of postoperative patients to appropriate level beneficial patient outcomes such as unanticipated intensive (ICU) admissions. The aim is assess whether inclusion intra- factors improves prediction deterioration ICU Methods A retrospective observational cohort study was performed between January 2013 December 2017 a tertiary Dutch...
For mechanically ventilated critically ill COVID-19 patients, prone positioning has quickly become an important treatment strategy, however, is labor intensive and comes with potential adverse effects. Therefore, identifying which intubated patients will benefit may help allocate resources. From the multi-center Dutch Data Warehouse of ICU from 25 hospitals, we selected all 3619 episodes in 1142 invasively patients. We excluded longer than 24 h. Berlin ARDS criteria were not formally...
Remote Photoplethysmography (remote PPG) enables contactless monitoring of the cardiac rhythm using video cameras. Prior research has shown feasibility video-based atrial fibrillation (AF) and/or flutter (Aflutter) detection in some scenarios, but most exclude patient movement. In this work, we investigate detecting these two arrhythmias a regular hospital environment an RGB camera, where patients were not limited movement during recording process. Data 56 was collected before and after...
Abstract Background The identification of risk factors for adverse outcomes and prolonged intensive care unit (ICU) stay in COVID-19 patients is essential prognostication, determining treatment intensity, resource allocation. Previous studies have determined on admission only, included a limited number predictors. Therefore, using data from the highly granular multicenter Dutch Data Warehouse, we developed machine learning models to identify ICU mortality, ventilator-free days ICU-free...
Point-of-care cardiovascular left ventricle ejection fraction (LVEF) quantification is established, but automatic tablet-based stroke volume (SV) with handheld ultrasound (HAND) devices unexplored. We evaluated a monoplane LVEF and LV tool (AutoEF) against computer-based (Tomtec) for SV quantification.
In this work, we investigated the feasibility of extracting continuous respiratory parameters from a single RGB camera stationed in short-stay ward. Based on extracted respiration parameters, further using features to aid detection atrial fibrillation (AF). To extract respiration, implemented two algorithms: chest optical flow (COF) and energy variance maximization (EVM). We used COF patient's thoracic area EVM facial area. Using capnography as reference, for average breath-to-breath rate...
The peak velocity variation within the carotid artery (ΔVpeakCCA) and left ventricular outflow tract (ΔVpeakLVOT) is derived from pulsed wave Doppler waveform may predict fluid responsiveness. aim of this study was to evaluate ΔVpeakCCA ΔVpeakLVOT against calibrated stroke volume (SVV) pulse pressure (PVV). Therefore, eighteen cardiac surgery patients were included in prospective observational study. measurements performed after induction anesthesia, a passive leg raise, at end surgery....
