This has created considerable confusion and overlapping terms in the medical literature. The 4 time-honored vital signs include temperature, pulse, blood pressure, and respiration. Two other measurements, blood oxygen saturation, and capnography (end-tidal CO2) are considered the fifth and sixth vital signs, respectively. The authors argue that exercise should be named a vital sign, and several authors have designated it as the fifth vital sign. However, not all symptoms or phenomena, such as exercise, are essential for life. This article traces the origins of the term \u201cvital sign,\u201d reports on the various conditions named the fifth through eighth vital signs, and proposes an objective definition that describes the requirements for designating something as a vital sign.<\/jats:p>","DOI":"10.36518\/2689-0216.2005","type":"journal-article","created":{"date-parts":[[2025,11,1]],"date-time":"2025-11-01T21:57:53Z","timestamp":1762034273000},"source":"Crossref","is-referenced-by-count":0,"title":["Exercise Promotes Health but Is Not a Vital Sign"],"prefix":"10.36518","volume":"6","author":[{"given":"Jacob","family":"Draves","sequence":"first","affiliation":[{"name":"Midwestern University Chicago College of Osteopathic Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Halil","family":"Tekiner","sequence":"additional","affiliation":[{"name":"Erciyes University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven H","family":"Yale","sequence":"additional","affiliation":[{"name":"University of Central Florida College of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eileen S","family":"Yale","sequence":"additional","affiliation":[{"name":"Wellington Regional Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"22435","published-online":{"date-parts":[[2025,10,31]]},"container-title":["HCA Healthcare Journal of Medicine"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,10,31]],"date-time":"2026-10-31T09:49:55Z","timestamp":1793440195000},"score":1,"resource":{"primary":{"URL":"https:\/\/scholarlycommons.hcahealthcare.com\/hcahealthcarejournal\/vol6\/iss5\/1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,31]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2025,10,31]]}},"URL":"https:\/\/doi.org\/10.36518\/2689-0216.2005","relation":{},"ISSN":["2689-0216"],"issn-type":[{"value":"2689-0216","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,31]]}}}
