Cortana weather forecast in Celsius. Cortana learns as it goes. What worked well for me was asking for weather in Celsius in my questions and after a while ( I think 7 - 9 responses) she started to provide the weather in Celsius by default. Other users reported that they asked her to show temperature in Celcius by default and she made it default.
A respiratory profile consists of measurements of different volumes within your lungs. How much air you breathe is determined by your activity level. The amount of air you inhale in a normal breath while at rest is called your tidal volume (TV). Your body needs more oxygen when performing strenuous work or exercise tasks. The inspiratory reserve volume (IRV) is the maximum additional lung volume
Measurement of lung volumes provides a tool for understanding normal function of the lungs as well as disease states. The breathing cycle is initiated by expansion of the chest. Contraction of the diaphragm causes it to flatten downward. If chest muscles are used, the ribs expand outward.The resulting increase in chest volume creates a negative pressure that draws air in through the nose and mouth. Normal exhalation is passive, resulting from ârecoilâ of the chest wall, diaphragm, and lung tissue.In normal breathing at rest, approximately one-tenth of the total lung capacity is used.he resulting increase in chest volume creates a negative pressure that draws air in through the nose and mouth.
