“…Those arresting outside the home were significantly younger, 60.9 -t 14.7, than the at-home arrest victims 67.9 -t 14.7 (p < 0.001). There was also a trend toward younger patients' receiving CPR more often, 64.8 13 reported a study in a geographic region overlapping ours. Their results are strikingly similar to those of the current study, despite a 10-year period between studies.…”

Objective: To identify characteristics associated with provision of bystander CPR in witnessed out‐of‐hospital cardiac arrest cases.Methods: An observational, prospective, cohort study was performed using cardiac arrest cases as identified by emergency medical services (EMS) agencies in Oakland County, MI, from July 1, 1989, to December 31, 1993. All patients who sustained a witnessed arrest prior to arrival of EMS personnel were reviewed.Results: Of the 927 patients meeting entry criteria, the 229 patients receiving bystander CPR were younger: 60.9 ± 14.7 vs 67.9 ± 14.7 years (p < 0.01). Most (76.6%) cardiac arrests occurred in the home. In a multivariate logistic model, only the location of arrest outside the home was a significant predictor of receiving bystander CPR [odds ratio (OR) 3.8; 99% CI 2.5, 5.9]. Arrests outside the home were associated with significantly improved outcome, with 18.2% of out‐of‐home and 8.2% of in‐home victims discharged from the hospital alive (OR 2.5; 99% CI 1.4, 4.4).Conclusion: Patients who have had witnessed cardiac arrests outside the home are nearly 4 times more likely to receive bystander CPR, and are twice as likely to survive. This observation emphasizes the need for CPR training of family members in the authors' locale. This phenomenon may also represent a significant con‐founder in studies of out‐of‐hospital cardiac arrest and resuscitation.

“…The value of early resuscitation initiated by a bystander is recognised [7]. Whilst it may take time to collect a Cardiff wedge, should the hospital be lucky enough to have one, during labour the attendant midwife is instantly available.…”

SummaryThe important part of resuscitation in late pregnancy is the relief of aortocaval compression. A manoeuvre to relieve aortocaval compression (the human wedge) is described and evaluated. Eighteen qualijied midwives performed basic life support in the supine and wedged position employing the human wedge. Performance was assessed using the Laerdal Resusci Anne Skillmeter. There was no diflerence ( p = 0.4761) in performance of mouth-to-mouth expired air ventilation between the two positions. External cardiac compressions were performed significantb better (p = 0.000s) in the wedged position than in the supine position. The human wedge may provide an alternative to other methods of relieving aortocaval compression.

“…Many reports provide data to compare the survival rates of cardiac arrest victims who receive "early" CPR (defined here as CPR initiated by citizens or bystanders) with the survival rates of those who receive "late" CPR (that CPR initiated by emergency responders) (22,25,27,38,46,52,53,64,66,89,90,95,97,(101)(102)(103)112). "Early" usually differs from "late" CPR by about four minutes.…”
