Consequence of the hypoventilation resulting from significant impediment of airflow through the obstructed airways is impaired gas exchange in the lungs. This leads to the increasing hypoxemia (PaO 2 45 mmHg). This condition is called the total respiratory failure. The persistence of hypoventilation ...
In patients with asthma,airway inflammationleads to variable levels of lowerairway obstructionthat affects both the small and large airways. Recurrent airflow limitation is caused bybronchoconstriction, airway edema, chronicmucusplug formation, andairway remodeling. Usually, the obstruction can be improved...
Congenital high airway obstruction syndrome (CHAOS) involves the partial or complete obstruction of the fetal upper airways, usually caused by atresia or stenosis of the larynx or trachea. The obstruction of bronchial tree leads to lung distension, diaphragmatic eversion, and cardiac dysfunction, which...
Tracheomalacia is a rare tracheal problem that leads to collapse of the airway and expiratory flow obstruction. Expiratory CT scans are the diagnostic test of choice in adults. Chronic obstructive pulmonary disease is the most common cause of adult tracheomalacia. Plication of the membranous wall to...
A UHS spokesman explained that the condition, known as chronic rhinosinusitis, leads to inflammation of the upper airways and causes nasal obstruction, facial pain, nasal discharge, catarrh, and a reduction in sense of smell. Nose bacteria may be resistant; UK & WORLD A total of 50 patients ...
Respiratory distress that leads to death is seen in patients with Lassa fever. The development of this respiratory problem was studied using a Pichinde virus model (104 plaque forming units, IP, survival time 20 卤 1 days) in strain 13 guinea pigs (n = 35, 229353 g) of this lethal ...

The growth imbalance in MPS IVA is attributed to the differential effects of the enzyme deficiency and the resultant accumulation of glycosaminoglycans (GAGs) on various tissues and organs [4, 5]. Incomplete ossification, coupled with progressive dysplasia of the bones and cartilage, leads to ...
This leads to carbon dioxide retention and hypoxemia. The client develops respiratory acidosis. Therefore, the PaCO2 level increase, the PaO2 level decreases, and the pH decreases, indicating acidosis. 80. 3. Corticosteroids have an anti-inflammatory effect and act to decrease edema in the ...
The above is important to avoid further airway remodeling. Abstract We aimed to evaluate asthmatic patients with fixed airways obstruction (FAO) and to verify the impact of follow-up in an asthma-dedicated outpatient clinic on symptoms control and spirometry compared to asthmatics without FAO. We...
