Hands-Only CPR is an effective method for assisting during cardiac emergencies, reducing the risk of disease transmission through mouth-to-mouth contact while still delivering life-saving chest compressions.

CPR that combines rescue breaths with chest compressions can be more physically demanding and complex. It requires remembering the correct breath-to-compression ratio and maintaining the rhythm of compressions, which can be challenging under stress. This complexity has led experts to reevaluate which component of CPR—compressions or rescue breaths—is most critical.

Research shows that continuous chest compressions alone may be more effective than interrupting compressions for rescue breaths.

Sustained compressions ensure consistent blood flow, while pauses for mouth-to-mouth can disrupt circulation, particularly in the crucial first minutes of cardiac arrest.

By focusing on Hands-Only CPR, individuals can deliver more uninterrupted chest compressions, maximizing the chances of survival and simplifying the process for rescuers.

Heart Hub does not collect any personal user information by default. It anonymously tracks the effectiveness of each user's CPR attempt, recording metrics such as compression depth, recoil, rate, and hand position.

Users can opt to receive a detailed performance breakdown by scanning a QR code, which provides the option to share their personal information with Heart Hub. This allows users to access information about first aid courses or location-specific rewards, such as incentives at a supermarket or airport.
