The value of spirometry in this asthmatic patient is that it gives
a non-invasive data that can be used to assess the severity of airway obstruction in patients
with acute exacerbations.
Interpret her spirometry by defining and analyzing each (FEV1, FVC, FEV1/FVC
ratio) individually. According to Pollart and Elward, (2009), Spirometry analysis of FEV1,
FVC, FEV1/FVC ratio FVC is the largest amount of air one is able to forcefully blow out
after deep breathing in. The FVC lower limit of normal (LLN) of people above 81 years is
70%. In Nancy’s case, FVC is 61% which is below the LLN.
FEV1 is the total of air
breathed out of lungs within 1 second. According to the American Thoracic society, normal
FEV1 is >80%. Nancy’s FEV1 is 61% implying that it is moderately abnormal. The normal
FEV1/FVC ratio for people above 18 years is above 70% (Nancy’s ratio is 69%). The low
FVC and FEV1/FVC ratio is an indicator of obstructed airways.
The significance of “atopy” and “one continuous airway” applying Nancy’s scenario.
Nancy’s asthma is most likely atopic.
Atopy is allergic development associated with patient
genetic. It is described by a heightened immune response to allergens. Asthma is not just one
disease but a myriad respiratory disease interaction of the one continuous airway (Pollart and
