    The main advantage of qualitative fit test methods is the low cost of equipment, while their main drawback is their modest precision, and that they cannot be used to test tight-fitting respirators that are intended for use in atmospheres that exceed 10 PEL (due to the low sensitivity). To reduce the risk of choosing a respirator with poor fit ...

    Respiratory pressure meter Measuring respiratory muscle strength is a long-established method of assessing the mechanics of breathing. Respiratory muscle dysfunction (i.e., reduced strength or endurance) should be distinguished from lung function abnormalities and measured separately.

  6. Pulmonary alveolus - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_alveolus

    Secondary septa are responsible for the final division of the sacculi into alveoli. Majority of alveolar division occurs within the first 6 months but continue to develop until 3 years of age. To create a thinner diffusion barrier, the double-layer capillary network fuse into one network, each one closely associated with two alveoli as they ...
