Abstract
Methods of sizing a nasal airway by using certain measurements of digits may include (a) pressing a distal portion of a digit of a hand against a resilient, flat surface, such that flesh of the distal portion of the digit spreads laterally on the surface; (b) measuring the digit's width at a digit measuring level, the measuring level being the widest part of the digit distal to a distal-most interphalangeal joint of the digit; and (c) identifying a nasal airway size as that size which correlates most closely to the digit's width as measured at the digit measuring level.
