Plethysmographic hyperinflation and well-controlled asthma: contribution and limitations of plethysmography [PDF]

open access: yesBatna Journal of Medical Sciences
Objective: Asthma control is usually assessed through clinical evaluation and spirometry, but these methods may overlook certain abnormalities, particularly air trapping. Plethysmography allows the detection of this pulmonary hyperinflation.
