PHOENIX, Oct. 8 (UPI) — U.S. researchers recommend bystanders use compression-only cardiopulmonary resuscitation to manually pump blood through the heart.
Conventional CPR also includes artificial respiration — exhaling into the patient to ventilate the lungs and pass oxygen into the blood.
Dr. Bentley Bobrow of the Arizona Department of Health Services in Phoenix and colleagues evaluated out-of-hospital bystander-CPR outcomes and found compression-only CPR associated with approximately 60 percent improved odds of survival versus conventional CPR or no CPR.
The study, published in the Journal of the American Medical Association, finds the survival rates for patients receiving compression-only CPR was 13.3 percent, 7.8 percent for those receiving conventional CPR and 5.2 percent for those with no CPR.
“Among patients who received bystander CPR, the proportion with compression-only CPR increased significantly over time, from 19.6 percent in 2005 to 75.9 percent in 2009,” the study authors write in a statement. “Overall survival also increased significantly over time: from 3.7 percent in 2005 to 9.8 percent in 2009.”
The study involved 4,415 cardiac arrest patients — 2,900 had no bystander CPR, 666 received conventional CPR and 849 had compression-only CPR.
