What is the pulse rate threshold for initiating chest compressions in adults?

The threshold for initiating chest compressions in adults is significant because it identifies a critical point in patient care during cardiac arrest or severe bradycardia. When the pulse rate is less than 30 beats per minute, the patient is at a heightened risk of inadequate blood circulation, which can lead to organ failure or death if not addressed promptly. In these situations, the heart is not effectively pumping blood to vital organs, making it essential to start chest compressions to restore circulation.

At a rate below 30/min, the likelihood of the patient being hemodynamically unstable is increased, justifying the need for immediate resuscitation efforts. Chest compressions help maintain blood flow to the brain and other vital organs until advanced medical care can take over, such as the use of medications or the application of electrical therapy (such as defibrillation).

Given this critical threshold, it is vital for responders to recognize when the heart rate drops to such a level that immediate intervention is required. Understanding this helps ensure that care is both timely and effective in supporting patient survival during emergencies.
