A mechanical device provides consistent and uninterrupted compressions to the sternum during cardiopulmonary resuscitation (CPR). This consistent pressure helps maintain blood flow to vital organs when the heart is unable to pump effectively. An example is the LUCAS device, which is strapped to the patient’s chest and performs automated compressions.
These devices offer several advantages. They eliminate provider fatigue, ensuring consistent depth and rate of compressions throughout a resuscitation attempt. This consistency can improve the chances of return of spontaneous circulation (ROSC) and minimize interruptions during critical interventions like defibrillation or intubation. Historically, manual CPR has been the standard, but the physical demands and variability in performance led to the development of mechanical alternatives. These devices play a vital role in both pre-hospital and in-hospital settings.
