ABSTRACT
STUDY OBJECTIVES: To compare the quality of CPR provided by medical students and pre-EMTs performing three-rescuer CPR with that achieved by same students trained to provide standard two-rescuer CPR and to find the most effective method of resuscitation and to educate this methods to students. MATERIAL AND
METHODS:
From July 1 to September 30, 1996, we had trained 60 groups consisted of the medical students, students of EMS technology and pre-EMT. Each group practiced two-rescuer CPR and three- rescuer CPR for 120 minutes with Resusci(R) Anne and performed CPR for at least 3 minutes without feedback. To eliminate any visual cues of performance the mannequin's recorder was hidden. Each actions were recorded by Resusci(R) skillmeter and Laerdal printer. To compare the Quality of two-rescuer CPR and three-rescuer CPR, we analyzed the data by SPSS with paired t-test.
RESULTS:
Three-rescuer teams delivered a mean minute ventilation and a mean minute cardiac compression substantially greater than that produced by two-rescuer teams(11.30 +/-.85 vs 9.09+/-.22, p<0.001, 99.22+/-2.42 vs 95.12+/-5.75, p<0.001). Three-rescuer teams produce the more correct actions in chest compression and ventilation(93.84+/-.56% vs 83.49+/-6.94%, 90.90+/-.33% vs 77.00+/-7.06%).
CONCLUSION:
Three-rescuers can produce better CPR than two rescuers when a bag-valve-mask devices is used and the technique is easily leaned and readily retrained, so we think that repeated education and training of this CPR methods to students is needed.
Key words: Two-rescuer, Three-rescuer CPR
