What lung values changed (from those of the normal patient) in the spirogram when the patient with emphysema was selected?

2 answers:

4 0

The lung values that changed include the following: ERV < IRV < RV < FVC < FEV1%. Spirogram is used to measure pulmonary function test. It is a test that tests the efficiency of the lungs to exchange carbon dioxide and oxygen gases. The vital capacity of the lung is equal to TV +IRV + ERV and the total capacity is equal to the summation of TV, IRV, ERV and RV.

When the patient with emphysema was selected lung values changed (from those of the normal patient) in the spirogram are:

ERV, IRV, RV, FVC, FEV1, FEV1 %

<span>The reason behind the changes of these values are due to the loss or inability of electric recoil. A spirogram (graph like structure obtained by the respiratory movements) is measured by spirometer.</span>

Procreation comes from pairing. In different phrases you have 2 codes for each little thing. you have the code from the father and the code from the mother. evaluate the code for blood. you're attentive to that there are 4 varieties of blood variety O, variety A and variety B and variety AB. If mom has 2 codes for her blood, enable us to declare O and O and father has 2 codes for his blood enable us to declare O and A There are a sequence variety of combinatins the 1st mom O can combine with father O, OO The 2d mom O can combine with father A, OA. the 1st mom O can combine with father A, OA The 2d mom O can combine with father O, OO the baby is going to have the two OO or OA. If the baby has OO the the baby has no selection different than to have blood variety O because of fact the expressed phenotype. If the baby has OA the A is dominate and it takes expression. subsequently the only way a recessive allele could be expressed is that if and on condition that there are 2 recessive allele as interior the case of OO. Now do the different combinations mom OO mom OA mom AA mom OB mom BB mom OO can combine with father OO making OO mom OO can combine with father OA making OA mom OO can combine with father AA making OA mom OO can combine with father OB making OB mom OO can combine with father BB making BB The recessive allele is expressed if and on condition that the two codes are recessive. What if mom is dominant A. mom AA mom OA can a recessive allele be produced particular If and on condition that the recessive O of the mother combines with a recessive O of the father. subsequently a mom dominant A might desire to be coded as OA and a father dominant A might desire to be coded as OA. the baby can get carry of mom O blended with the father O and be OO, the recessive. the baby is recessive even whilst the mothers and dads are dominant because of fact the mothers and dads carried the recessive allele. this might ensue if and on condition that the two mothers and dads carry the recessive allele. pass via the mixture mom OA Father AA you will by no capacity get a recessive phenotype expressed

It has a charge shift, which basically means, since there are 2 charges, that it'll filp it's charge:
