The only difference between normal persons and persons with a collapsed lung is that the latter when called upon to increase their ventilation reach their limit a little sooner than the former.<\/jats:p>\n               <jats:p>From these findings we might deduce that there will be no dyspnea except after moderate exertion. And this deduction is borne out by the histories of the patients.<\/jats:p>\n               <jats:p>In other words, in the lungs, as in other organs, there is a large factor of safety, one lung being as efficient as two, except when the work done calls for more than a threefold increase in the normal ventilation.<\/jats:p>","DOI":"10.1084\/jem.24.6.671","type":"journal-article","created":{"date-parts":[[2004,6,17]],"date-time":"2004-06-17T23:20:47Z","timestamp":1087514447000},"page":"671-681","update-policy":"http:\/\/dx.doi.org\/10.1084\/jem.crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["THE VARIOUS FACTORS OF RESPIRATION IN PERSONS WITH PNEUMOTHORAX"],"prefix":"10.1084","volume":"24","author":[{"given":"J.
