    Obesity hypoventilation syndrome (OHS)

    Air is breathed in through the nasal passageways, travels through the trachea and bronchi to the lungs.

    Obesity hypoventilation syndrome (OHS) is a condition in some obese people in which poor breathing leads to lower oxygen and higher carbon dioxide levels in the blood.

    Obstructive sleep apnea

    Massively enlarged tonsils can cause episodes of cessation of breathing known as obstructive sleep apnea.  Cessation of breathing can last 10 seconds or longer, causing extremely low levels of oxygen in the blood.

    With obstructive sleep apnea, your breathing pauses while you are asleep because your airway has become narrowed or partly blocked.

    Occupational Asthma

    Spirometry is a painless study of air volume and flow rate within the lungs. Spirometry is frequently used to evaluate lung function in people with obstructive or restrictive lung diseases such as asthma or cystic fibrosis.

    Occupational asthma is a lung disorder in which substances found in the workplace cause the airways of the lungs to swell and narrow. This leads to attacks of wheezing, shortness of breath, chest tightness, and coughing.
