The ratio of cardiopulmonary resuscitation (CPR) compressions to ventilation is the ratio of the number of chest compressions to the number of artificial respirations during CPR resuscitation of a patient in cardiac arrest.
When a patient suffers from respiratory arrest, emergency CPR is essential to save the patient’s life. Its main procedures include chest compressions, opening the airway, and artificial respiration. These actions can help establish basic life support for the patient and ensure essential blood and oxygen supply to the body’s vital organs.
When performing cardiopulmonary resuscitation current guidelines recommend two artificial breaths for every 30 cardiac compressions, at which point the compression-ventilation ratio is 30:2, and care should be taken to keep the airway open during the process at the same time. CPR can be continued at this ratio until the patient awakens or receives more advanced life support.
If you encounter a patient with suspected cardiac arrest, it is recommended that you call for help immediately and dial 120.
