As an expert in emergency medical response, I can provide you with a detailed explanation on how often you should stop CPR to check for signs of life. It's crucial to understand the importance of uninterrupted chest compressions in maintaining blood flow to the brain and other vital organs during a cardiac arrest situation. The American Heart Association (AHA) provides guidelines on this matter, which I will outline below.

Step 1: English Answer

When performing CPR, it is essential to maintain a high-quality standard, which includes minimizing interruptions in chest compressions. According to the AHA guidelines, you should perform cycles of 30 chest compressions followed by 2 rescue breaths (referred to as "30:2" ratio). The chest should be compressed straight down about 2 inches (5 cm) for adults, and about 1.5 to 2 inches (4-5 cm) for children.

Frequency of Checking for Signs of Life:


1. Adult Victims: For adult victims, you should check for signs of life, breathing, and a pulse every 2 minutes (or after 5 cycles of 30:2 CPR, which equates to approximately 100 compressions). This 2-minute interval allows for a reasonable duration of CPR to potentially restore a pulse and spontaneous breathing without causing significant interruption to the chest compressions.


2. Child and Infant Victims: In the case of children and infants, the recommendation is similar. You should check for signs of life, breathing, and a pulse every 2 minutes. However, it's important to note that for infants, the primary cause of cardiac arrest is often asphyxiation, and thus, rescue breaths are crucial. The compression-to-ventilation ratio remains the same (30:2) for children and infants to ensure an adequate amount of chest compressions.


3. Interruptions: Minimizing interruptions is key. Any pause in chest compressions for more than a few seconds can significantly reduce the victim's chance of survival. Therefore, checks for signs of life should be brief and should not last more than 10 seconds.


4. Signs to Look For: When checking for signs of life, you are looking for normal breathing, coughing, or movement. A pulse check is also performed, typically on the carotid artery in adults and the brachial artery in children.


5. Continuation of CPR: If there are no signs of life, you should continue with CPR. It's important to reassess the situation regularly, as the effectiveness of CPR can change over time.


6. Professional Help: Always call for professional medical help as soon as possible. CPR is a temporary measure, and the victim will need advanced medical care as soon as an ambulance arrives.
