Introduction
Knowing when pauses in compressions occur during CPR (Cardiopulmonary Resuscitation) can be a lifesaver in CPR. Pausing too often can interrupt blood flow, impacting the victim’s chance of survival. Whether you’re a healthcare professional or a bystander, these guidelines can help increase the chance of survival. Keep reading to learn when pauses are necessary while performing high quality CPR and to keep it as effective as possible.
When Do Pauses in Compressions Occur During CPR?
When someone experiences sudden cardiac arrest, chest compressions are one of the most effective actions a bystander can take to increase their survival chances. However, in many situations, compressions aren’t continuous from start to finish. There are moments when you may need to pause, depending on the situation. Below are the common scenarios where pauses occur:
-
Checking for Signs of Life or Pulse
One instance when you stop compressions is to check if the person has started showing signs of life, such as normal breathing or a pulse. Typically, this happens after every two minutes of continuous compressions. You’ll stop briefly to assess whether the person’s condition has changed.
This step allows you to decide whether to continue CPR or adjust your actions. If a pulse or normal breathing is present, chest compressions may no longer be needed. On the other hand, if no signs of life are detected, resuming compressions quickly is required. Pauses during this check should not exceed 10 seconds, as prolonged gaps can reduce the effectiveness of CPR. Timing these checks efficiently is important.
-
Defibrillation Using an AED
Pauses also occur when using an Automated External Defibrillator (AED). After attaching the AED pads to the person’s chest, the device will analyze their heart rhythm and determine if a shock is needed. During this analysis, you’ll be prompted to stop compressions.
If the AED advises a shock, pausing compressions prevents interference with the analysis and allows the device to deliver the shock safely. Once the shock is delivered, you must resume compressions right away. Following the AED’s prompts and handling these pauses smoothly helps maintain effective care.
-
Delivering Rescue Breaths or Ventilations
When performing CPR as part of a two-person team or using a bag-mask device, pauses are needed to deliver breaths. This is done in cycles using the approach of 30 chest compressions followed by 2 breaths.
These brief pauses allow oxygen to be delivered to the person’s lungs. Proper coordination between the person giving compressions and the one providing breaths is key to keeping the process smooth. Syncing compressions with ventilations ensures that pauses are brief and effective.
-
Switching Rescuers
If CPR continues for an extended period, fatigue can set in, making it difficult to keep compressions at the right depth and speed. Switching roles with another rescuer helps maintain high-quality compressions. These role changes introduce brief pauses, but with proper coordination, they can be done quickly.
Switching every two minutes is a common approach to avoid fatigue and maintain steady compressions. Communication between rescuers is essential during these moments to keep the process flowing.

Technique for Compressions
Chest compressions are designed to mimic the heart’s pumping action, pushing blood through the body to prevent brain and organ damage. This section covers the key techniques involved in chest compressions. These are detailed below:
Hand Placement and Body Position
Placing hands correctly on the chest ensures that compressions effectively circulate blood. The correct position is the center of the chest, right on the lower half of the breastbone. Rescuers should place one hand over the other, interlocking their fingers, and use the heel of the bottom hand to apply pressure. This position allows compressions to reach the depth needed to pump blood effectively. Maintaining this position also reduces the risk of rib fractures, a common concern in CPR.
Body position also matters greatly. Rescuers should position themselves directly above the victim’s chest, keeping their arms straight. This allows for more controlled, effective compressions and prevents rescuer fatigue, especially when performing CPR for extended periods. Using body weight instead of arm strength ensures compressions remain consistent, improving the odds of survival.
Compression Depth and Rate
The recommended depth for adults is about 2 inches, which helps ensure that each compression pumps sufficient blood to vital organs. Shallow compressions, on the other hand, do not create enough blood flow. Compressions at or near the recommended depth improve survival chances significantly. However, compressions should not be too deep, as excessive force may cause injuries.
The rate of compressions also matters. Experts recommend a pace of 100 to 120 compressions per minute.
Avoiding Pauses and Minimizing Interruptions
Pausing too often during CPR can quickly decrease its effectiveness. It’s important to minimize the time when pauses in compressions typically occur to avoid reducing blood flow. Ideally, compressions should only be paused briefly for actions like switching rescuers, analyzing with an AED, or delivering rescue breaths if trained to do so.

Impact of Unnecessary Pauses
In CPR, every second matters. Unnecessary pauses in chest compressions can quickly reduce the chances of survival for someone in cardiac arrest. It’s important to know while performing high-quality CPR when do pauses happen, as this can impact the effectiveness of compressions.
Disrupted Blood Flow and Oxygen Delivery
When chest compressions are interrupted, blood flow to the brain and vital organs decreases almost instantly. During CPR, compressions act as the heart’s pump, delivering oxygen to the body. A brief pause in compressions can lead to a significant drop in blood pressure, reducing oxygen levels in the brain. This reduction impacts the victim’s chance of recovery, as prolonged oxygen deprivation can cause permanent brain damage within just a few minutes.
Keeping blood flow steady is especially important because each time compressions resume, it takes several compressions to build blood pressure back up. In a real emergency, consistently delivering blood and oxygen is what helps prevent further harm, making continuous compressions a vital part of effective CPR.
Lowered Chances of Return of Spontaneous Circulation (ROSC)
ROSC is the point when the heart resumes an effective rhythm on its own, often seen as a key goal during CPR. Frequent pauses in compressions lower the chances of achieving ROSC because they disrupt the steady blood flow that supports heart function.
Even brief pauses can make it harder to achieve ROSC, as the heart may struggle to restart its own rhythm when blood flow is irregular. Knowing this, professional CPR guidelines strongly emphasize maintaining the flow of compressions whenever possible.
Increased Fatigue in Rescuers
Pauses in compressions typically occur and contribute to rescuer fatigue, especially in prolonged resuscitation efforts. Switching rescuers is necessary to keep compressions strong and effective, but unplanned pauses or extended breaks can disrupt this process, leaving rescuers feeling more exhausted. Rescuer fatigue can make CPR less effective. Studies using manikins (fake models) show that after 1 to 3 minutes of performing chest compressions, the quality of compressions drops. This happens because the person giving CPR becomes tired, which can slow down or weaken their compressions, making it harder to keep blood flowing properly.
To combat fatigue and avoid unnecessary pauses, CPR guidelines recommend switching rescuers approximately every two minutes. Practicing smooth transitions during training allows rescuers to step in seamlessly, reducing the time compressions are paused and helping maintain their quality. This teamwork approach not only supports the victim’s chance of survival but also ensures that rescuers can sustain their efforts for as long as needed.
Tips for Minimizing Pauses During CPR
In CPR, every second of continuous chest compressions matters. Unnecessary pauses disrupt the flow of blood, reducing oxygen to the brain and heart. Professionals should focus on keeping pauses brief to maximize the effectiveness of CPR. In this section, you will learn while performing high-quality CPR when do pauses in CPR occur to help you minimize interruptions, ensuring each compression counts when it matters most.
Prepare Equipment and AED in Advance
When do pauses in compression happen during CPR is when, rescuers switch or when using an AED. When an AED is accessible, place it beside the victim and attach the pads as soon as possible. This readiness allows you to quickly analyze the heart rhythm without significantly delaying compressions.
Communicate and Coordinate with Other Rescuers
Clear communication with other rescuers helps avoid overlap or confusion, which can lead to unnecessary pauses. If more than one person is performing CPR, agree on a set rhythm and decide who will take over at specific intervals. Effective coordination can decrease transition times between rescuers by seconds, maintaining blood flow consistency. This teamwork allows each rescuer to rest briefly without losing compression quality.
Limit Pauses to Essential Actions Only
When pauses in compressions typically occur they should be reserved for tasks, such as analyzing with an AED or administering rescue breaths if trained to do so. Avoid stopping for non-critical reasons, as every pause lowers blood pressure, which then takes time to rebuild.
Practice Proper Compression Techniques Regularly
Frequent practice helps build muscle memory, allowing you to perform compressions consistently and confidently. CPR courses often include simulation-based training that prepares rescuers to act swiftly under pressure.
Use Feedback Devices When Available
Feedback devices, which are sometimes included in AEDs or CPR manikins, can help improve the quality of compressions. These devices provide real-time guidance on depth, rate, and recoil, helping you maintain optimal compression standards. Feedback devices can improve compression consistency and reduce unnecessary pauses, ultimately increasing the chances of a successful outcome.
Minimizing Pauses in Compressions During CPR
Pauses in compressions during CPR can significantly impact the victim’s survival chances. The right techniques, like preparing equipment, coordinating with rescuers, and practicing proper techniques, will help you minimize the interruptions. Even brief pauses reduce the oxygen supply to vital organs, so every second counts. Knowing when and how pauses in compressions occur during CPR can make a life-saving difference.
