Contact-free measurement of heart rate, respiration rate, and body movements during sleep

Contact-free Estimation of Respiration Rates during Sleep

A 5.8GHz multi-channel Doppler radar bio-motion sensor for contact-less and convenient measurement of respiration rate in the home was developed and used to measure respiration of a subject. This paper reports on the accuracy of the non-contact sensor respiration rate estimates obtained using signal processing methods compared to a gold standard reference of expert manually scored respiration r...

Oscillations of heart rate and respiration synchronize during poetry recitation.

The objective of this study was to investigate the synchronization between low-frequency breathing patterns and respiratory sinus arrhythmia (RSA) of heart rate during guided recitation of poetry, i.e., recitation of hexameter verse from ancient Greek literature performed in a therapeutic setting. Twenty healthy volunteers performed three different types of exercises with respect to a cross-sec...

Heart rate variability during nap sleep.

Benzodiazepine hypnotics increase heart rate during sleep.

The cardiovascular effects of benzodiazepines administered intravenously as preoperative sedatives have received considerable study, but sleep laboratory research on benzodiazepines administered orally as hypnotics has not focused on assessment of cardiovascular changes. Analysis of heart rate (HR) data collected in sleep laboratory studies on the effects of 0.5 mg of triazolam (Halcion) and 30...

changes in body temperature, respiration, heart rate and certain serum biochemical parameters of sheep during summer heat stress in jiroft

background: sheep are a form of investment and a quickly liquidatable resource, particularly in traditional and low income production systems. tropical and long warm-season regions always affect sheep production negatively. methods: in this experiment 15 female and 7 male sheep were chosen and their body temperature, heart rate, respiration rate measurements and blood sample for biochemical par...
