  2. Nasal congestion - Wikipedia

    en.wikipedia.org/wiki/Nasal_congestion

    Nasal congestion is the partial or complete blockage of nasal passages, leading to impaired nasal breathing, usually due to membranes lining the nose becoming swollen from inflammation of blood vessels.

  3. Empty nose syndrome - Wikipedia

    en.wikipedia.org/wiki/Empty_nose_syndrome

    Mason called the turbinates "the most important organ in the nose" and claimed they were "slaughtered and removed with discriminate abandon more than any other part of the body, with the possible exception of the prepuce." [25] The term "Empty Nose Syndrome" was first used by Eugene Kern and Monika Stenkvist of the Mayo Clinic in 1994. [3]

  4. Obstructive sleep apnea - Wikipedia

    en.wikipedia.org/wiki/Obstructive_sleep_apnea

    Use of CPAP definitively primarily expands a collapsed upper airway, allowing for nasal breathing – and positive use of CPAP would prove that airway collapse is the cause of OSA.

  5. Human nose - Wikipedia

    en.wikipedia.org/wiki/Human_nose

    There is a reinforcing structure known as the nasal scroll that resists internal collapse from airflow pressure generated by normal breathing. This structure is formed by the junction between the lateral and major cartilages.

  6. Nasal cycle - Wikipedia

    en.wikipedia.org/wiki/Nasal_cycle

    A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the subconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals. This results in greater airflow through one nostril with ...

  7. Continuous positive airway pressure - Wikipedia

    en.wikipedia.org/wiki/Continuous_positive_airway...

    The application of positive pressure may be intended to prevent upper airway collapse, as occurs in obstructive sleep apnea, or to reduce the work of breathing in conditions such as acute decompensated heart failure. CPAP therapy is highly effective for managing obstructive sleep apnea.

  8. Sinusitis - Wikipedia

    en.wikipedia.org/wiki/Sinusitis

    Acute sinusitis can present as facial pain and tenderness that may worsen with staining or bending over, headache, cough, bad breath, nasal congestion, ear pain, ear pressure or nasal discharge that is usually green in color, and may contain pus or blood. [20] Dental pain can also occur.

  9. Müller's maneuver - Wikipedia

    en.wikipedia.org/wiki/Müller's_maneuver

    After a forced expiration, an attempt at inspiration is made with closed mouth and nose, whereby the negative pressure in the chest and lungs is made very subatmospheric; the reverse of a Valsalva maneuver. This technique is designed to look for collapsed sections of airways such as the trachea and upper airways. In this maneuver, the patient ...
