Study	Study Design	Study Population	Methods	Significant Findings
Osborne C.A. et al., 2000 [6]	Case-Control Study	23 asymptomatic asthmatics, 17 healthy subjects	Measured various stable state parameters	PaCO2 and PETCO2 lower in asymptomatic asthmatics
Van den Elshout et al., 1991 [7]	Case- Control Study	30 asthmatics, 17 healthy subjects	Induction of hypercapnia and hypocapnia	Hypocapnia induced increases in airway resistance in asthmatic patients
Raimondi et al., 2013 [8]	Case series	314 patients admitted for ASA	ABGs, electrolytes and spirometry results documented	Hypocapnia was prominent in less severe asthma exacerbations

Abbreviations used: ASA = acute severe asthma, ABGs = arterial blood gases, PETCO₂ = end-tidal carbon dioxide.
