This work presents a stretchable elastomer optical fiber sensor incorporated into a belt for
respiratory rate (RR) and heart rate (HR) monitoring. Different materials and shapes of …

Background Classic spectral analysis of heart rate variability (HRV) in pediatric sleep apnea–
hypopnea syndrome (SAHS) traditionally evaluates the very low frequency (VLF: 0–0.04 …

Abstract Pediatric Obstructive Sleep Apnea (OSA) is a respiratory disease whose diagnosis
is performed through overnight polysomnography (PSG). Since it is a complex, time …

Pediatric obstructive sleep apnea (OSA) is a breathing disorder that alters heart rate
variability (HRV) dynamics during sleep. HRV in children is commonly assessed through …

The ideal moment to withdraw respiratory supply of patients under Mechanical Ventilation at
Intensive Care Units (ICU), is not easy to be determined for clinicians. Although the …

Background: Breathing pattern alterations change the variability and spectral content of the
RR intervals (RRi) on electrocardiogram (ECG). However, there is no method to record and …

In spite of the increasing prevalence of asthma worldwide, it often remains underdiagnosed
and untreated, causing permanent damage to lungs. In this scenario, early diagnosis and …

Heart rate variability (HRV) is a reliable measure of an individual's physical and mental
fitness. Monitoring HRV over time provides crucial indicators of various health issues and …

Advances in wireless networks and wearable electronic devices have enabled the
monitoring of massive physiological data for disease diagnosis. In this article, we aim to …

Background Patients with severe asthma often have uncontrolled disease and experience
mood disorders, particularly anxiety and depression. The autonomic nervous system (ANS) …
