What is the recommended BLS compressions rate to ensure adequate circulation?

The recommended compressions rate for Basic Life Support (BLS) to ensure adequate circulation in an adult patient is 100 to 120 compressions per minute. This range is optimal for maintaining blood flow and ensuring that enough oxygen-rich blood reaches the vital organs during cardiopulmonary resuscitation (CPR).

The rate of 100 compressions per minute is specifically emphasized in guidelines to balance the efficiency of achieving adequate blood flow without compromising the quality of compressions. At this rate, the rescuer can effectively perform deep, firm compressions while allowing for adequate recoil between compressions, which is crucial for maintaining blood circulation.

Higher rates, such as 120 or 140 compressions per minute, although they may sound appropriate in terms of urgency, can lead to fatigue and ineffective compressions. If compressions are too rapid, they may not be deep enough to create sufficient pressure to circulate blood effectively, which can hinder the chance of successful resuscitation. Therefore, the priority in BLS is to maintain a compressions rate of around 100 per minute to achieve optimal results.
