diagnosis:
The case is most likely Chronic Obstructive Pulmonary disease (COPD) especially emphysema

-Pt is smoker which is important risk foctor for developing emphysema
-Arterial blood gases are law and CXR shows hyperinflated chest

-Close relatives of people with emphysema are more likely to develop the same disease
-Older age is a risk factor for emphysema Lung function normally declines with age

Other close differential diagnosis is lung cancer due to age + smoking

Correct answer  Dr kasem and Dr hersi  the diagnosis is COPD (chronic bronchitis in this case).
COPD has two types: Emphysema, Chronic bronchitis.but my question about  this case ABG shows pao2=16kpa, Paco2=9kpa, ph=7.20 but in COPD patient ABG shows hypoxia, low pao2, normal or raised Paco2.
The diagnosis is deterioration of COPD (chronic bronchitis due to supplemental of high concentration of oxygen mostly in ambulance which lead to hypoventilation , hypercapnia and impairment of the level of consciousness.


SO AVOID HIGH OXYGEN CONCENTRATION IN COPD PATIENT
