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
Lung volumes are directly measured; Lung capacities are inferred from lung volumes. The average total lung capacity of an adult human male is about 6 litres of air, but only a small amount of this capacity is used during normal breathing.Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath.pecific changes in lung volumes also occur during pregnancy. Functional residual capacity drops 18â20%, typically falling from 1.7 to 1.35 litres, due to the compression of the diaphragm by the uterus.
