CCF during resuscitation may improve if there is a focus on improving these factors and requires validation in multicentric settings.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jets.jets_36_21","type":"journal-article","created":{"date-parts":[[2021,11,23]],"date-time":"2021-11-23T06:15:12Z","timestamp":1637648112000},"page":"41-46","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":12,"title":["Chest Compression Fraction and Factors influencing it"],"prefix":"10.4103","volume":"15","author":[{"given":"Deo","family":"Mathew","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
