Webb2 nov. 2016 · #1. Pulse oximetry is a better measurement of oxygen delivery to the tissues. PaO2, the oxygen tension in arterial blood, is the best way to determine how well the lungs are working. However, oxygen saturation is a better measurement of the systemic oxygen delivery to the tissues (DO2) (7): Webb9 okt. 2024 · Average blood pressure and pulse are 120/80 mm Hg and 60 to 80 beats per minute, respectively. 17. Thirty breaths per minute is a normal respiratory rate for children up to 12 years of age. 1 In adults, the normal respiratory rate is up to 18 breaths per minute. A rate of 30 breaths per minute in a resting adult is considered abnormal and …

Webb6 mars 2008 · Introduction Pleth Variability Index (PVI) is a new algorithm that allows continuous and automatic estimation of respiratory variations in the pulse oximeter waveform amplitude. Our aim was to test its ability to detect changes in preload induced by passive leg raising (PLR) in spontaneously breathing volunteers. Methods We conducted … Webb• RDI (Respiratory Disturbance Index) is used to assess the severity of sleep apnea by measuring respiratory efforts, or RERAs (Respiratory Effort Related Arousals). A RERA is an arousal from sleep that follows 10 seconds or more of increased respiratory effort but does not meet the criteria for apnea or hypopnea.
