Fusion-Based Approach for Respiratory Rate Recognition From Facial Video Images

IEEE Access, 2020
The respiratory rate is an important vital parameter that provides information about persons' physical condition. In clinical practice it is currently only monitored using contact-based techniques, which can have negative effects on patients.

Mechanical Power during Veno-Venous Extracorporeal Membrane Oxygenation Initiation: A Pilot-Study

Membranes, 2021
Mechanical power (MP) represents a useful parameter to describe and quantify the forces applied to the lungs during mechanical ventilation (MV). In this multi-center, prospective, observational study, we analyzed MP variations following MV adjustments ...

Post-harvest quality of papaya coated with polivinilic alcohol and maize starch [PDF]

Ciência e Agrotecnologia, 2020
Climacteric fruits have short postharvest shelf life. Coating is an alternative to minimize fruit ripening and post-harvest losses. Maize starch (S) and polivinilic alcohol - PVOH (P), isolated or blended, can be used in the formulation of coatings ...

Performance of Contactless Respiratory Rate Monitoring by Albus Home^TM, an Automated System for Nocturnal Monitoring at Home: A Validation Study

Sensors, 2022
Respiratory rate (RR) is a clinically important predictor of cardio-respiratory deteriorations. The mainstay of clinical measurement comprises the manual counting of chest movements, which is variable between clinicians and limited to sporadic readings ...

Early detection of deterioration in COVID-19 patients by continuous ward respiratory rate monitoring: a pilot prospective cohort study

Frontiers in Medicine, 2023
BackgroundTachypnea is among the earliest signs of pulmonary decompensation. Contactless continuous respiratory rate monitoring might be useful in isolated COVID-19 patients admitted in wards. We therefore aimed to determine whether continuous monitoring
