As noted above, patients considering DNR mention the risks of CPR. Physical injuries, such as broken bones, affect 13% of CPR patients,<ref name="boland">{{cite journal | vauthors = Boland LL, Satterlee PA, Hokanson JS, Strauss CE, Yost D | title = Chest Compression Injuries Detected via Routine Post-arrest Care in Patients Who Survive to Admission after Out-of-hospital Cardiac Arrest | journal = Prehospital Emergency Care | volume = 19 | issue = 1 | pages = 23–30 | date = January–March 2015 | pmid = 25076024 | doi = 10.3109/10903127.2014.936636 | s2cid = 9438700 }}</ref> and an unknown additional number have broken cartilage which can sound like breaking bones.<ref name="creighton">{{Cite web |url=http://heartsavercpromaha.com/cpr-review---keeping-it-real.html |title=CPR Review - Keeping It Real |website=HEARTSAVER (BLS Training Site) CPR/AED & First Aid (Bellevue, NE) |access-date=2018-12-12 |archive-date=2018-12-15 |archive-url=https://web.archive.org/web/20181215222028/http://heartsavercpromaha.com/cpr-review---keeping-it-real.html |url-status=dead }}</ref><ref name="emt">{{Cite web |url=http://emtlife.com/threads/cpr-breaking-bones.23116/ |title=CPR Breaking Bones |website=EMTLIFE |date=25 May 2011 |access-date=2018-12-12}}</ref>

Mental problems affect some patients, both before and after CPR. After CPR, up to 1 more person, among each 100 survivors, is in a coma than before CPR (and most people come out of comas<ref name="katz">{{Cite journal |last1=Katz |first1=Douglas I. |last2=Polyak |first2=Meg |last3=Coughlan |first3=Daniel |last4=Nichols |first4=Meliné |last5=Roche |first5=Alexis |date=2009-01-01 |editor-last=Laureys |editor-first=Steven |editor2-last=Schiff |editor2-first=Nicholas D. |editor3-last=Owen |editor3-first=Adrian M. |title=Natural history of recovery from brain injury after prolonged disorders of consciousness: outcome of patients admitted to inpatient rehabilitation with 1–4 year follow-up |series=Coma Science: Clinical and Ethical Implications |publisher=Elsevier |volume=177 |pages=73–88}}</ref><ref name="neurol">{{Cite journal |last1=Giacino |first1=Joseph T. |last2=Katz |first2=Douglas I. |last3=Schiff |first3=Nicholas D. |last4=Whyte |first4=John |last5=Ashman |first5=Eric J. |last6=Ashwal |first6=Stephen |last7=Barbano |first7=Richard |last8=Hammond |first8=Flora M. |last9=Laureys |first9=Steven |date=2018-08-08 |title=Practice guideline update recommendations summary: Disorders of consciousness |journal=Neurology |volume=91 |issue=10 |pages=450–460 |doi=10.1212/WNL.0000000000005926 |pmid=30089618 |pmc=6139814 |issn=0028-3878}}</ref>).

* ''In US hospitals'' a study of 12,500 survivors after CPR, 2000–2009, found: 1% more survivors of CPR were in comas than before CPR (3% before, 4% after), 5% more survivors were dependent on other people, and 5% more had moderate mental problems but were still independent.

* ''Outside hospitals'', half a percent more survivors were in comas after CPR (0.5% before, 1% after), 10% more survivors were dependent on other people because of mental problems, and 21% more had moderate mental problems which still let them stay independent. This study covered 419 survivors of CPR in Copenhagen in 2007-2011.  {{doi|10.1016/j.resuscitation.2013.10.033}} and works cited.</ref>
