Oximetry: This measures oxygen levels in the blood.Ventilation/perfusion (VQ) scan: Doctors can see airways and blood flow to the lungs.Chest CT scan: To look for tumors, foreign bodies, and much more.Lateral soft tissue X-ray of the neck: This shows adenoids and tonsils when they're enlarged, the oral and nasal airways, part of the trachea (windpipe), and the epiglottis.For example, about 30% of missed lung cancers occur due to scanning errors when reading chest X-rays. Chest X-ray: It's important to note that while a chest X-ray can be very helpful in diagnosis, a negative chest X-ray can't necessarily rule out several lung conditions.Mental status: Confusion or loss of consciousness may occur due to low oxygen levels ( hypoxia).Gum disease/dental decay: Dental infections and decay may suggest a lung abscess or aspiration pneumonia.Lymph nodes: Enlarged lymph nodes just above the collar bones (supraclavicular lymph nodes) or neck (cervical lymph nodes) may be associated with lung cancer or lymphomas in the chest.Use of accessory muscles: The diaphragm is the primary muscle used in breathing, but with respiratory distress, the use of accessory muscles in the neck and chest can sometimes be a telltale sign of trouble.Nasal flaring: Widening of the nostrils with breathing may be a sign of difficulty breathing in children and adults who are unable to describe their symptoms.Clubbing is associated with lung disease, especially lung cancer or interstitial lung disease, though it can sometimes also be seen in healthy people. Clubbing: This describes fingers that take on an upside-down spoon appearance.Cyanosis refers to a bluish appearance of the fingers, lips, and mouth that is associated with low oxygen content in the blood.

Skin color: A glimpse at a person's skin color may demonstrate pallor due to anemia, which can cause rapid breathing.
