Deep learning for predicting respiratory rate from biosignals

Comput. Biol. Medicine, 2022
In the past decade, deep learning models have been applied to bio-sensors used in a body sensor network for prediction. Given recent innovations in this field, the prediction accuracy of novel models needs to be evaluated for bio-signals.

Weakly Supervised rPPG Estimation for Respiratory Rate Estimation

2021 IEEE/CVF International Conference on Computer Vision Workshops (ICCVW), 2021
Recent studies demonstrate that respiratory rate can be estimated from skin videos through analyzing the frequency domain attributes of their remote photoplethysmography (rPPG).

An Index Combining Respiratory Rate and Oxygenation to Predict Outcome of Nasal High-Flow Therapy.

American Journal of Respiratory and Critical Care Medicine, 2019
Rationale: One important concern during high-flow nasal cannula (HFNC) therapy in patients with acute hypoxemic respiratory failure is to not delay intubation.

Increasing Cardiac Rate by Tracking the Respiratory Rate

Pacing and Clinical Electrophysiology, 1984
Un stimulateur asservi qui utilise la fréquence venlilatoire comme capteur a été implunté chez 22 patients, dont 19 pour la stimulation ventriculaire et 3 pour la stimulation auriculaire. Le niveau d'exercice atteint en utilisant ce système a été toiijours supérieur à celui de la stimulation ventriculaire à fréquence fixe.

Respiratory Rate as a Determinant of Optimal Pacing Rate

Pacing and Clinical Electrophysiology, 1983
Des essais ont été faits dans ľutilisation des paramètres bialogiques pour déterminer la fréquence optimale de stimulation cardiaque. Dans cette étude, le rapport entre fréquence respiratoire et fréquence cordiaque a étéétabli chez 67 patients au cours de ľexercice.

Heart Rate and Respiratory Rate Monitoring Using Seismocardiography

2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021
Vital signs monitoring is critical for healthcare. Currently, at-home vital signs monitoring is obstructed by the complicated device, unaffordable cost, and inconvenience. In this study, we develop a simultaneous heart rate and respiratory rate monitoring technique that requires only one tri-axial accelerometer placing on the sternum.

RESPIRATORY RATES IN PEDIATRIC EMERGENCY PATIENTS

Southern Medical Journal, 1990
Respiratory rates are routinely measured in pediatric emergency patients. The normal range has not been established, and commonly reported ranges seem lower than those encountered in clinical practice. This prospective study selected subjects from pediatric patients presenting for care to a suburban emergency department.

Noncontact Monitoring of Respiratory Rate in Newborn Infants Using Thermal Imaging

IEEE Transactions on Biomedical Engineering, 2019
Monitoring of respiratory rate (RR) is very important for patient assessment. In fact, it is considered one of the relevant vital parameters in critical care medicine.
