Experimental results demonstrated that a mean correlation of 0.95 and a mean Root-Mean-Square Error (RMSE) of 0.11 breaths per minute (bpm) were achieved when comparing to a reference signal obtained from a spirometer.Lorenz, Anna LenaZhang, Song...

Simulation durations vary: 1 second for a rapid breathing pattern at 60 breaths per minute (BPM), 2 seconds for a median breathing pattern at 30 BPM, and 4 seconds for a slow breathing pattern at 15 BPM, as depicted in Fig. 2. A study by Kolanjiyil and Kleinstreuer (2017) indicates...
63K Breathing rate, or respiratory rate, is an individual's number of breaths per minute. Learn the definition and calculation of breathing rate and discover the mechanism of breathing rate regulation. Related to this Question Ask a Homework Question ...
The accelerometer data correlated closely with veterinary lab vitals monitoring equipment, with mean absolute errors of 0.5 breaths/min for respiratory rate (RR) and 1.6 beats/min for heart rate (HR). MIT researchers achieved the first human trial of the ingestible sensor. Image used cour...
Reardon 2007). Air is one of the most vital needs for human survival. It is an undeniable fact that people cannot exist without air. The quality of the air directly affects human well-being because a person takes breaths per minute. 7000 chemicals are identified in second-hand tobacco smoke...
Mice were anesthetized (5% isoflurane), intubated and kept at 1.75% isoflurane/5% oxygen by active ventilation with constant respiratory frequency (85 breaths per minute; Animal-Respirator-Advanced, TSE-Systems). Magnetic resonance imaging (MRI) was performed at 7 and 9.4T (Bruker Biospin MRI, E...
In case of the 1 liter Tedlar bag, it took about 1 minute to fill it with 4–5 breaths. For each measurement of both groups, the whole gas system was cleaned several minutes by dry air and evacuated down to 10−4 mbar. Tedlar bags were also used for estimating the error bars...
The tidal volume was 2.5 mL, and the respiratory rate was 63 breaths/min. Animals were placed in a supine position on a heating pad. A left lateral thoracotomy at the fourth intercostal space exposed the anterior surface of the heart, after which, the location of the LAD coronary artery ...
The above results indicate that the sensor has a higher frequency resolution than the normal respiratory rate (16-20 breaths per minute) and can be used in practical nursing applications. Figure 5. (a) Experimental setup for monitoring human breath; (b) the response characteristics of the ...
