In emphysema, the Forced Vital Capacity (FVC) typically remains normal or may slightly decrease, but the key change is a reduction in the Forced Expiratory Volume in 1 second (FEV1). This results in a decreased FEV1/FVC ratio, indicating an obstructive pattern of lung disease. The primary issue in emphysema is the loss of elastic recoil in the lungs, leading to difficulties in exhaling air efficiently.

Would an emphysema patient have larger SVC or FVC?
In emphysema, the forced vital capacity (FVC) is typically reduced due to loss of elastic recoil in the lungs and air trapping, while the slow vital capacity (SVC) may be less affected or even appear normal. However, both measures can vary among patients. Generally, FVC is often smaller than SVC in emphysema patients due to the obstructive nature of the disease. Thus, an emphysema patient would more likely have a larger SVC compared to FVC.
What does emphysema increase?
Basically smoking, as the most common cause of emphysema is smoking itself.
Does emphysema decrease lung volume?
It increases their RV (residual volume) and FRC (functional residual capacity) due to air trapping. It decreases the FEV1 and takes longer to finish their FVC (forced vital capacity) because of decreased flow rates. It also decreases the DLCO (difusion capacity) because of alveolar wall distruction.
Why patient with emphysema thin?
Because emphysema reduce the oxygen perfusion (transfer) from alveoli into the blood thus also reduce the oxygen supply to the muscle and organ. Reduce the oxygen delivery to the periphery cause weight loss and thus they (emphysema patient) look thin.
Is emphysema genetic or inherited?
Emphysema can have genetic components, but it is not typically directly inherited like a Mendelian genetic disorder. Certain genetic factors can increase the likelihood of developing emphysema, particularly in combination with environmental factors like smoking.
How can the spread of emphysema be controlled?
Emphysema does not "spread"-- it is NOT contagious.However, the incidence of emphysema can be reduced if all countries and persons reduce lung irritants and air pollution. ANY strong chemical is a lung irritant. Smoking is just one of a long list of lung irritants.
What lung values changed in the spirogram when the patient with emphysema was selected?
In a spirogram of a patient with emphysema, key lung values typically show a decreased forced expiratory volume in one second (FEV1) and a reduced FEV1/FVC (forced vital capacity) ratio, indicating obstructive lung disease. Additionally, total lung capacity (TLC) may be increased due to air trapping, while residual volume (RV) is also elevated. These changes reflect the impaired airflow and hyperinflation characteristic of emphysema.
Why has your body got bigger now you have emphysema?
If you are on steroids to treat inflammation that causes emphysema, your body can add weight. If you are also retaining fluid from heart disease, your weight can increase.
How does emphysema reduce oxygen in blood?
the tar like substance prevents your lungs from taking in enough oxygen.

What causes diminished breath sounds in emphysema?
The person's lungs are not moving air well in emphysema. Also irritants cause increased production of phlegm, which can reduce air movement, hence, diminished breath sounds.
