Advancements in Remote Photoplethysmography

Electronics
Advancements in camera technology over the past two decades have made image-based monitoring increasingly accessible for healthcare applications. Imaging photoplethysmography (iPPG) and remote photoplethysmography (rPPG) are non-invasive methods for measuring vital signs, such as heart rate, respiratory rate, oxygen saturation, and blood pressure ...

Photoplethysmography in the assessment of venous insufficiency [PDF]

Journal of Vascular Surgery, 1987
Photoplethysmography has been used simultaneously with ambulatory venous pressure measurements to study 32 patients. Of the 62 limbs studied, 24 were normal, 20 had primary varicose veins, and 18 had deep valvular incompetence. The results indicate that the photoplethysmographic refilling time can provide a good separation between the three groups when

Seminars in epileptology: Holistic management of epilepsy in adults with intellectual development disorders

Epileptic Disorders, EarlyView.
Abstract This seminar addresses the complexity of the management of epilepsy in adults with intellectual development disorders (IDD), advocating holistic and multidisciplinary care aligned with the learning objectives of the International League Against Epilepsy. Epilepsy is significantly more prevalent in people with IDD, presenting unique diagnostic,

Artificial intelligence for adaptive neuromodulation in drug‐resistant epilepsy

Epilepsia, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects nearly one third of people with epilepsy and is associated with substantial cognitive, psychiatric, and mortality burdens. For patients who are not candidates for resection or laser interstitial thermal therapy, neuromodulation therapies such as vagus nerve stimulation, deep brain stimulation, and ...

Wireless Photoplethysmography (PPG) Measurement with Pulse Wave Velocity (PWV) Method for Arterial Stiffness Evaluation

Jurnal Rekayasa Elektrika
Indications of symptoms of cardiovascular disease can be seen from the level of elasticity of the arteries. The Pulse Wave Velocity (PWV) method using PPG signal analysis is used to determine the level of arterial stiffness based on the time difference ...

Effect of epileptogenesis on hypercapnic cardioventilatory response in kainic acid rats

Epilepsia, EarlyView.
Abstract Objective Cardioventilatory failure is the leading mechanism proposed to underlie sudden unexpected death in epilepsy (SUDEP), which occurs predominantly at night in patients with generalized tonic–clonic seizures. Interictal hypercapnic cardioventilatory responses are suggested to be involved, as they are ablated in chronically epileptic ...
