What is the best indicator of an obstructive lung disorder?
FEV1 and FEV1/FVC values of the spirometric test are the best indicators for airway obstruction.
What are at least 2 symptoms of chronic obstructive pulmonary disease?

- Shortness of breath, especially during physical activities.
- Wheezing.
- Chest tightness.
- A chronic cough that may produce mucus (sputum) that may be clear, white, yellow or greenish.

What is Dahl’s sign?
Dahl’s sign, a clinical sign in which areas of thickened and darkened skin seen on the lower thighs and/or elbows, is seen in patients with severe chronic respiratory disorders such as chronic obstructive pulmonary disease (COPD), interstitial lung disease, congestive heart failure (CHF), and chronic moderate to severe …
What confirms a diagnosis of COPD?
The most effective and common method for diagnosing COPD is spirometry. It’s also known as a pulmonary function test or PFT. This easy, painless test measures lung function and capacity. To perform this test, you’ll exhale as forcefully as possible into a tube connected to the spirometer, a small machine.
How is obstructive lung disease diagnosed?
Tests may include:
- Lung (pulmonary) function tests. These tests measure the amount of air you can inhale and exhale, and whether your lungs deliver enough oxygen to your blood.
- Chest X-ray. A chest X-ray can show emphysema, one of the main causes of COPD .
- CT scan.
- Arterial blood gas analysis.
- Laboratory tests.
How is COPD diagnosed?
What is Dahl’s sign positive?
Dahl’s sign (also Thinker’s sign or Target sign) is a clinical sign in which areas of darkened (hyperpigmentation) and thickened (hyperkeratotic) skin are seen on the lower thighs and elbows. It occurs in patients with longstanding severe chronic obstructive pulmonary disease.
What are the gold standard diagnostic tests for COPD?
Spirometry is considered the gold standard for confirming the diagnosis of chronic obstructive pulmonary disease (COPD) and assessing treatment response. Studies find that using it can improve the care provided and overall outcomes of COPD patients in primary care settings.
What were your first COPD symptoms?
The early signs and symptoms of COPD can include the below.
- Chronic cough. A persistent or chronic cough is often one of the first symptoms of COPD.
- Excess mucus production. Producing too much mucus can also be an early symptom of COPD.
- Shortness of breath and tiredness.
How do you detect COPD?
a blood oxygen test – a peg-like device is attached to your finger to measure the level of oxygen in your blood. a CT scan – a detailed scan that can help identify any problems in your lungs. a phlegm sample – a sample of your phlegm (sputum) may be tested to check for signs of a chest infection.
What is COPD GOLD classification?
GOLD 1 – mild: FEV1 ≥80% predicted. GOLD 2 – moderate: 50% ≤ FEV1 <80% predicted. GOLD 3 – severe: 30% ≤ FEV1 <50% predicted. GOLD 4 – very severe: FEV1 <30% predicted.
What causes pigeon chest?
One possible cause is when the tissue that connects the breastbone to the ribs grows too much. Another cause might be when parts of the bone itself grow too much. Sometimes it happens following open heart surgery. Pigeon chest seems to run in families.
Does COPD cause barrel chest?
COPD. Chronic obstructive pulmonary disease (COPD) is an umbrella term for several kinds of lung diseases that occur when airflow is blocked from the lungs. This can happen because of lung swelling, scarring, mucus, and other damage. Symptoms include wheezing, difficulty breathing, shortness of breath, and barrel chest …
What is Hoover’s sign in COPD?
Hoover’s sign is a frequent finding in COPD, and the frequency increases with severity. The sign can also be present in patients with congestive heart failure, asthma, severe pneumonia (especially in children), bronchiolitis, as well as seen unilaterally in diaphragmatic paralysis, pleural effusion and pneumothorax.
What is Hoover’s sign?
Jump to navigation Jump to search. Hoover’s sign in pulmonology is one of two signs named for Charles Franklin Hoover. It refers to inward movement of the lower rib cage during inspiration, – instead of outward as is normal – implying a flat, but functioning, diaphragm, often associated with COPD.
Is Hoover’s sign useful in the diagnosis of asthma?
There have been no studies conducted on the sensitivity and specificity of Hoover’s sign in asthma. There is no data available either on the cost savings that may be induced by using Hoover’s sign as opposed to use of chest roentgenography, pulmonary function tests or arterial blood gases, for example.
How persistent is Hoover’s sign persistence?
The duration of persistence of Hoover’s sign, its appearance or disappearance in relationship to exacerbations and remissions and the influence of aggressive therapy on extent of retraction are hitherto unknown.
