Fig. 2 pressure-volume diagram of elastic work (curves bcd and hjk) and resistive (non-elastic) work (curves bic and hello’j) executed by the lung throughout respiratory at (a) ambient airway stress and (b) with cpap.
Cpap decreased each elastic and non-elastic work masses as expressed by the world underneath the curves hjk and hello’j in contrast with bcd and bic respectively.
(reproduced with permission from katzjnd,maik§. ,il9§5. ). ). Using in a single day polysomnography knowledge from 1741 randomly-sampled members of the final inhabitants [3, 4], one of many authors (eob) developed a multivariable linear regression mannequin for predicting ahi on the premise of age, intercourse, race, bmi, and menopausal standing.
Based on this mannequin, we have been in a position to evaluate the ahis of our iih sufferers with the imply ahis of a lot of population-based controls “matched” to our sufferers by age, intercourse, race, bmi, and menopausal standing.
