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 ...

Extracting Instantaneous Respiratory Rate From Multiple Photoplethysmogram Respiratory-Induced Variations [PDF]

Frontiers in Physiology, 2018
In this study, we proposed a novel method for extracting the instantaneous respiratory rate (IRR) from the pulse oximeter photoplethysmogram (PPG). The method was performed in three main steps: (1) a time-frequency transform called synchrosqueezing transform (SST) was used to extract the respiratory-induced intensity, amplitude and frequency variation ...

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 ...

Regularity of Respiratory Waveform Depends on Ventilation Parameters [PDF]

, 2020
Entropy is a nonlinear method for quantifying the regularity and order of a system. Entropy was originally born from thermodynamics and is now used in various fields, such as statistical mechanics and information ethics.

Assessment of neonatal respiratory rate variability

Journal of Clinical Monitoring and Computing, 2022
AbstractAccurate measurement of respiratory rate (RR) in neonates is challenging due to high neonatal RR variability (RRV). There is growing evidence that RRV measurement could inform and guide neonatal care. We sought to quantify neonatal RRV during a clinical study in which we compared multiparameter continuous physiological monitoring (MCPM) devices.

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

Quiet Time for Mechanically Ventilated Patients in The Medical Intensive Care Unit [PDF]

, 2016
Objective: Sleep disruption occurs frequently in critically ill patients. The primary aim of this study was to examine the effect of quiet time (QT) on patient sedation frequency, sedation and delirium scores; and to determine if consecutive QTs ...

ECG-Derived Respiratory Rate in Atrial Fibrillation [PDF]

IEEE Transactions on Biomedical Engineering, 2020
The present study addresses the problem of estimating the respiratory rate from the morphological ECG variations in the presence of atrial fibrillatory waves (f-waves). The significance of performing f-wave suppression before respiratory rate estimation is investigated.The performance of a novel approach to ECG-derived respiration, named "slope range" (

Sex differences in emotional concordance. [PDF]

, 2020
Emotions involve response synchronization across experiential, physiological, and behavioral systems, referred to as concordance or coherence. Women are thought to be more emotionally aware and expressive than men and may therefore display stronger ...

Effect of external PEEP in patients under controlled mechanical ventilation with an auto-PEEP of 5 cmH2O or higher. [PDF]

, 2016
In some patients with auto-positive end-expiratory pressure (auto-PEEP), application of PEEP lower than auto-PEEP maintains a constant total PEEP, therefore reducing the inspiratory threshold load without detrimental cardiovascular or respiratory effects.
