Static Lung Volume: Helium Dilution

Static Lung Volume: Helium Dilution

what are lung volumes and capacities, various lung volumes such as tidal volume etc..
what and why can/cannot be measured by simple spirometery
why are lung capacities calculated by adding other volumes and other capacities
what can be determined by using the helium dilution method – how to carry out the helium technique in order to find out the residual volume of lungs – why is helium used?
why are static lung volumes measured
contraindications for performing static lung volume test are..
the functional residual capacity of the lungs equation.
functional residual capacity of the lungs is compared to the expected value for the patient, depending on their age, height and weight. a young healthy males total lung capacity would expected to be approx. 6 litres. certain factors if smoke. obese etc..
a persons lung volume can be decreased due to….
a persons lung volume can be increase to due to…
emphysema, lung cancer etc
