(Elsevier Science IncNew York, 2017)
A Signal Processing Method for Respiratory Rate Estimation through Photoplethysmography
(Sciencie &Engineering Research Support Society (SERSC), 2018-02)
Monitoring of respiration is crucial for determining a patient´s health status, specially
previously and after an operation. However, many conventional methods are difficult to
use in a spontaneously ventilating patient. ...
Pre- and postoperative evaluation by photoplethysmography in patients receiving surgery for lower-limb varicose veins
(International Journal Of Vascular Medicine, 2014)
Objective. To evaluate the effectiveness of surgery in treating primary varicose veins in the lower limbs by photoplethysmography (PPG) and duplex mapping (DM). Method. Forty-eight lower limbs were clinically evaluated ...

Wearable device prototype for vital signs monitoring
(CASE, 2022)
Monitoring vital signs is a basic need in healthcare institutions. Due to the limited capacity of these facilities, wearable devices have emerged aiming to aid ambulatory monitoring and doctors’ daily activities. This work ...
Can We Assess Pulsus Paradoxus through Polysomnography in a Patient with Chronic Obstructive Pulmonary Disease and Sleep-Disordered Breathing?
(American Academy of Sleep Medicine, 2016)
Pulsus paradoxus (PP) is a decrease in systolic blood pressure greater than 10 mm Hg during inspiration that occurs in various medical conditions. Using polysomnography pulse oximetry signal, photoplethysmography variations ...
Respiratory rate estimation on embedded system.
(CASE, 2022)
We present the design, implementation, and results of an algorithm for respiratory rate estimation using respiratory induced frequency, intensity, and amplitude variation calculated from the photoplethysmography (PPG) ...
