beaty is a novel device that allows effective chest compressions by providing audible indications when reaching a depth of 5cm.
Many studies have shown that the depth of chest compressions is related to the improvement in survival rates and favorable functional results of OHCA, the results suggest that applying the 51 mm depth recommended in the current AHA guideline can improve outcomes in victims of PCEH.
The objective of this study is to evaluate the relationship between chest compression depth and survival to arrests Р(СЕН.) Of 593 out-of-hospital victims, 13 patients (22,9%) recovered spontaneous circulation, 63 patients (10,6 .50%) survived and 8,4 achieved favorable functional results (53.6%) mean compression depth was significantly greater in survivors (95 mm, 50.5% CI: 56.7-47.6) than in non-survivors CI: 50.0- XNUMX).
Out-of-hospital cardiac arrests
The study demonstrated that the depth of chest compressions is related to improved survival rates and favorable functional results in OHCHR, the results suggest that applying the 51mm depth, recommended in the current AHA guidelines, can improve results. in PCEH victims.
The purpose of this study was to measure the quality of PCR performed outside hospitals by ambulance personnel, measured according to international CPR guidelines.
The defibrillators used in these cases recorded chest compressions via a sternal pad fitted with an accelerometer, and ventilation via changes in chest impedance, in addition to standard events and ECG recordings.
In this study of CPR during out-of-hospital cardiac arrests, chest compressions were not performed in numerous cases, and when they were performed, most were too superficial. Specifically, the mean depth of chest compressions was 34 mm (95% CI, 33-35 mm).
Untrained rescuers should perform compression-only (hands-only) CPR, with or without the assistance of the 112 emergency telephone operator, for an adult cardiac arrest victim.
During manual CPR, rescuers should perform chest compressions to a depth of at least 5 cm in an adult of normal build.
Most monitoring signals obtained through CPR feedback devices indicate that chest compressions are more likely to be too shallow than too deep.
The depth of compressions can be difficult to assess without feedback devices.
