< 0.70 (FEV1 / FVC)

30% < FEV1 > 50% of predicted

24
Q

What is a Very Severe COPD Classification?

A

< 0.70 (FEV1 / FVC)

FEV1 < 30% of predicted
FEV1 < 50% of predicted in presence of chronic respiratory failure

25
Q

What measurement tool is considered essential for COPD diagnoses?

A

Spirometry

26
Q

A

400 ug Salbutamol

27
Q

In stage 1 of COPD, what are some subjective patient identifiers associated with the symptoms?

A

Patient is usually unaware that his/her lung function is abnormal

28
Q

In stage 2 of COPD, what are some subjective patient identifiers associated with the symptoms?

A

Patients typically seek medical attention b/c of chronic respiratory symptoms or an exacerbation of their disease.

29
Q

A

Symptoms almost have an impact on the patients quality of life.

30
Q

In stage 4 of COPD, what are some subjective patient identifiers associated with the symptoms?

A

Quality of life is significantly impaired and exacerbations may be life threatening.

34
Q

In Exercise Testing for COPD Patients what are some physiological function assessments?

A

GXT (cardiorespiratory) & Spirometry (pulmonary)

35
Q
