airway

Four patterns of airway obstruction can be recognised on CXR: (i) airway narrowing; (ii) ball-valve effect; (iii) expansile pneumonia; and (iv) lobar collapse.

Peritonsillar abscess is most common in persons 20 to 40 years of age (13); however, it is less likely to cause upper airway obstruction, unless it is bilateral.

In the total general population sample, airway obstruction characterized by pulmonary function studies was more common in subjects with SZ and ZZ genotypes than in subject with the MM genotype, whereas frequency of airway obstruction was unaffected in subjects with the MZ genotype (Table 1).

The mass, which occurred in a 19-year-old woman of Asian descent, caused nasal airway obstruction in the setting of cervical lymphadenopathy that was initially ascribed to mononucleosis.

Mechanical airway obstruction secondary to retropharyngeal haematoma is a life-threatening emergency that should be anticipated in all patients with cervical spine injuries, regardless of the severity of trauma or surgery.

s Manual Jet Ventilator and Transtracheal Catheter may be the emergency intervention of choice for the patient with facial trauma, partial airway obstruction, upper airway bleeding, or otherwise difficult airway access and management.

In the previous case series, most South African women had mild and moderate airway obstruction (16 of 22) and a decreased diffusion capacity (13 of 17), whereas the remainder had normal (5 of 22) or mild restriction (1 of 22) (Grobbelaar and Bateman 1991).

As our case illustrates, upper airway obstruction is seen in IM, which sometimes may mimics nasopharyngeal lymphoma.

A study conducted at the New York University School of Medicine found that urban elderly with asthma were most commonly sensitized to CR allergens and that CR sensitization was associated with increased airflow limitation, hyperinflation, and irreversible airway obstruction.

Asthma is caused by inflammation of the lower airways and airway obstruction that can be caused by mucus or muscle spasms.

Anthonisen of the University of Manitoba in Winnipeg and his colleagues at 10 clinical centers in the United States and Canada began the Lung Health Study by recruiting 5,887 smokers, age 35 to 60, with mild airway obstruction but no noticeable breathing trouble.

Asthma is a chronic lung disorder characterized by reversible airway obstruction and a pathologic finding of airway inflammation.

Myxomas of the vocal fold are rare benign tumors often presenting with chronic dysphonia and less frequently with airway obstruction.

Previously, one of the authors (KBG) reviewed the coronial inquest of the death of a patient from acute airway obstruction from Ludwig's angina (5).

The MVV test is most useful in the verification of the degree of airway obstruction in patients suspected of not giving maximum effort, for example, in industrial legal testing.
