A randomized, controlled trial of 69 CPR providers in the United Kingdom recently showed the increased efficacy of using real-time feedback by way of an infant resuscitation manikin.
Resuscitation manikins are commonplace in many CPR training classes. In adult classes “Resuscitation Annie” has been used since 1960 and has helped an estimated 400 million learn CPR. She is fondly referred to as the “Mother of CPR.” In addition to the adult manikin, many training seminars utilize a child and infant manikin. Sometimes, the entire Resuscitation Family can be found on the site. More recently, the traditional Resuscitation Annie has been replaced with a high-tech, instant feedback manikin to help train providers.
There are several benefits to using manikins, especially resuscitation manikins that provide real-time feedback. Thanks to technology, it is now possible to practice on a manikin that simulates correct CPR and provides landmarks to assist the trainee in proper hand placement. These manikins use LED indicators with audio and visual cues to allow medical professionals to see and hear when the compressions they perform are correct and efficient. The chest also rises when the proper head-tilt/chin lift is performed, and the airway is properly opened.
When training for CPR, four key indicators are stressed: Chest compression depth, release force, chest compression rate and compression duty cycle. In this randomized trial, infant manikins were used in 50% of the training. The manikin offered feedback that allowed trainees to see, immediately, if the chest compressions they were performing were accurate and useful. When using the two-finger chest compressions, participants were able to achieve the four key targets 75% of the time. When using the two-thumb chest compressions, participants were able to meet the four key objectives 80% of the time.
According to the results of the study, the use of the real-time feedback infant manikin increased the effectiveness of chest compressions dramatically, increasing efficiency from <0.1% to 75-80%. The use of real-time feedback infant resuscitation manikins has proven useful in CPR training, and medical professionals are hoping that they will be utilized as frequently as possible in order to improve the quality of chest compressions. If this data were to be transferred to a clinical setting, this technology could allow medical providers to learn better how to perform proper CPR, thereby increasing the possibility of positive outcomes in a clinical setting.
So, if these manikins are so useful, why are they not used for every training class? Several companies make these manikins, including Laerdal, Armstrong, and Preston. However, the biggest reason they are not always used comes down to money. One infant manikin can cost over $400, a hefty price for training centers to pay, especially when more than one is needed.
Resuscitation manikins are also useful in training providers in what to do if an infant/child/adult is choking. Despite the high cost of these high-tech manikins, the increased efficacy may prove more beneficial than the price.
