Adult Cardiopulmonary Resuscitation (CPR)

Heart symbol indicates Physio-Control discussion points and commentary, including helpful links to supporting data.

Adult CPR Highlights

  • Lone healthcare provider (HCP) compression-to-ventilation ratio of 30:2 for all victims.
  • Two-rescuer HCPs perform 30:2 ratio on adult victims
  • Lay rescuers no longer perform checks for signs of circulation and use a 30:2 compression ventilation ratio (for all victims).
  • All rescuers no longer perform pulse checks during the use of an AED
  • No pauses for ventilation during compressions with an advanced airway in place. Ventilations are delivered at a rate of 8-10 breaths/minute (approximately).
  • "Effective" chest compressions are essential for providing blood flow during CPR. The rule is: "push hard & push fast."
  • New recommended energy levels for monophasic and biphasic defibrillation.

Adult CPR — Healthcare Provider

There are new statements about doing two minutes of CPR after each shock and in some cases providing two minutes of CPR before shock for unwitnessed out-of-hospital VF.

It is now recommended a compression-to-ventilation ratio of 30:2 be used for single rescuers treating victims of all ages and 2 - rescuer CPR for adults. Healthcare providers should use a 15:2 ratio for 2 rescuer CPR for infants and children." Class IIa. (p. IV-25).

"...recommend that all rescuers minimize interruptions of chest compressions for checking the pulse, analyzing rhythm, or performing other activities. Class IIa. (p. IV-25).

There is a growing body of evidence indicating any interruptions are detrimental to outcome. cprMAX technology will greatly assist in addressing this area of the Guidelines.

During 2 rescuer CPR with an advanced airway, rescuers provide continuous compressions (100 compressions/minute) and the rescuer giving the rescue breaths does so at a rate of 8 - 10 breaths/minute. Class IIa.(p. IV-22)

"Effective" chest compressions are essential for providing blood flow during CPR (Class I). The rule is: "push hard and push fast." Rescuers must provide compressions of an adequate rate (100/minute) and depth (1.5-2 inches) and allow complete chest recoil with minimal interruptions. Also, the compression/relaxation ratio of each compression should be 50:50. Class IIb. (p. IV-24)

Fatigue is a major factor in compression quality. When 2 or more rescuers are performing CPR, it is reasonable to switch the compressor every 2 minutes. Class IIb. (p. IV-25)

The emphasis on more CPR, more effective CPR, more consistent CPR and on rescuer fatigue makes mechanical CPR assist devices an important consideration, especially for ouot-of-hospital cardiac arrest situations.
