When possible, what is the preferred method of CPR?
- Compression-only 2. Single-person 3. Two-person 4. Rescue-breath-only
The Correct Answer and Explanation is :
The preferred method of CPR (Cardiopulmonary Resuscitation) when possible is Compression-only CPR (Option 1).
Explanation:
Compression-only CPR, also known as hands-only CPR, focuses solely on chest compressions without the incorporation of rescue breaths. This method has been shown to be effective, particularly for adults who suffer from sudden cardiac arrest. The rationale behind this approach is that when a person experiences cardiac arrest, blood flow to vital organs needs to be restored as quickly as possible. Chest compressions help maintain circulation by pushing blood through the heart and into the rest of the body, especially the brain, which is critically sensitive to a lack of oxygen.
Studies have demonstrated that compression-only CPR is as effective as traditional CPR (which includes rescue breaths) for adults in out-of-hospital cardiac arrest situations. This is particularly important because many bystanders hesitate to perform CPR due to concerns about giving mouth-to-mouth breaths, which can be uncomfortable or unfeasible in some situations. By simplifying the process to only chest compressions, more people are likely to intervene in emergencies, thereby increasing the overall survival rates.
The recommended technique for compression-only CPR involves placing the hands at the center of the chest and performing compressions at a rate of 100 to 120 per minute, with a depth of about two inches. It is crucial to allow full recoil of the chest between compressions to maintain blood flow.
While two-person CPR and rescue breath techniques may be beneficial in specific situations, such as pediatric cases or in cases involving drowning, compression-only CPR is generally preferred for adults. It is important for bystanders to recognize the importance of acting quickly and confidently, as immediate intervention can significantly improve outcomes for cardiac arrest victims.
