When someone's heart stops, every second counts. Rescuers must perform chest compressions to keep blood flowing to the brain and vital organs. Because these compressions can be physically demanding for humans, many hospitals use mechanical devices to provide consistent pressure. However, a common concern is whether these machines cause more internal damage than manual chest compressions.
A review of existing data looked at several types of injuries, including broken ribs, sternum fractures, and liver damage. The results showed no statistically significant difference between machine-assisted CPR and manual CPR for any of these specific injuries. This includes complications like bleeding or damage to the lungs and chest cavity.
While the numbers suggest that machines are as safe as human hands in these areas, it is important to note that the evidence quality is currently low to very low. Because the data comes from a limited pool of studies, doctors should still be cautious when interpreting these results. The findings do not officially confirm that mechanical CPR is perfectly safe, but they show no clear increase in injury risk.
