Because of this, the 1999 American Thoracic Society (ATS) guideline for methacholine and exercise testing recommended that caffeine-containing products be withheld on the day of testing [1].

A recent American Thoracic Society (ATS) guideline1 recommends two different methods of methacholine challenge testing: the 2-min tidal breathing method, and the five-breath dosimeter method. In the 2-min tidal breath-ing method, up to 10 twofold increases in concen-tration of methacholine are placed in a nebulizer

hensive series of joint American Thoracic Society/European Respiratory Society (ATS/ ERS) statements on lung function testing.2 5 One of the problems arising from those has been the view that patients either pass or fail the criteria set down in those statements. This was not the intention of the group who prepared those statements. Aspects


1999 ATS guidelines outlined the use of Methacholine concentration to define the fall of 20% of FEV1 (PC20). A PC20 of > 16 mg/ml was considered a normal bronchial response, less than 16 were graded as borderline, mild or moderate responses. The new 2017

asthma in adults

The ERS/ATS guidelines on severe asthma published in 2014 define severe asthma as asthma which requires treatment with high dose inhaled corticoster-oids (ICS) plus a second controller or systemic CS, which remains uncontrolled despite this therapy, or to prevent it from becoming uncontrolled [1]. Hence,

ATS GUIDELINES FOR METHACHOLINE AND EXERCISE CHALLENGE TESTING To the Editor: The Guidelines (1) are timely, useful, and well balanced. However, although they are in general evidence-based, the rationale of some recommendations remains unconvincing. 1. The use of PC 20 /PD 20, including the choice of the highest FEV 1 value, is no longer arbitrary.
