How Does It Work? Oura derives your respiratory rate exclusively from your nighttime PPG data –the same signal it uses to measure your resting heart rate and heart rate variability. Nighttime is an ideal time to measure respiration because your body is in a consistent state. During the day,...
During physical exercise, respiratory rate depends on the individual and can vary from about 30 to 60 breaths per minute, while minute volume (ventilation) can range from about 50 to 100 liters per minute. How to measure one’s own breathing at rest? In order to define your breathing patte...
In this paper, a new method to measure respiratory airflow rate using the pressure inside a sealed nose has been described. The method is based on the Pitot tube principle and involves using a pressure microsensor connected to the sealed nasal cavity. There is no need to capture the total ...

the measure of how easily the lungs expand under pressure is compliance. breathing is regulated unconsciously by center in the brainstem. these centers adjust the rate and rhythm of breathing according to changes in the composition of the blood, especially the concentration of carbo 24、n dioxide....
Here’s how this feature will work: To measure your respiratory rate, you just need to place your head and upper torso in view of your phone’s front-facing camera and breathe normally. To measure your heart rate, simply place your finger on the rear-facing camera lens. ...
We conclude that the prelimbic prefrontal cortex contributes to generation of tachypnoeic responses to prolonged stressors, but does not contribute to respiratory arousal in response to brief stressors. 展开 关键词: Prelimbic prefrontal cortex Medial prefrontal cortex Respiratory rate Tidal volume Arousal...
