What is the VAM (Voice Assisted Manikin)

Voice-Assisted Manikin (VAM) Training is a CPR training manikin that provides instant, standardized feedback. As learners practice, the manikin gives corrective audio prompts (and often visual cues) to ensure proper technique.

VAM technology is a key feature in many blended-learning programs, including the American Heart Association’s HeartCode® courses. In these programs, students first complete the online portion, then demonstrate hands-on skills with a VAM. Acting like a personal coach, the VAM objectively guides and evaluates essential CPR skills such as compression depth, rate, recoil, hand placement, and ventilation timing and volume.

Research shows that automated voice feedback not only improves initial CPR skill learning but, in some cases, performs just as effectively as instructor-led training for specific skills. Because of this, VAM is recognized as a reliable tool for verifying CPR competency in blended courses and as a valuable complement to instructor-based training.

What is the AHA HeartCode® program?

The American Heart Association’s HeartCode® programs are blended-learning courses for BLS (Basic Life Support), ACLS (Advanced Cardiovascular Life Support), and PALS (Pediatric Advanced Life Support). cpr.heart.org+2cpr.heart.org+2

Rather than doing the entire course in person, HeartCode allows learners to complete the cognitive (knowledge) portion online—at their own pace—before attending a hands-on skills session where CPR, AED use, airway management, and other life-support procedures are practiced and tested. cpr.heart.org+3cpr.heart.org+3cpr.heart.org+3

Key features & benefits

Self-paced online learning: Students can log in/out, work in segments, and proceed when ready. elearning.heart.org+3cpr.heart.org+3cpr.heart.org+3
Adaptive / scenario-based content: The 2020 version uses a “True Adaptive™” algorithm to personalize the path through content, plus “Cognitive Assessment Activities” (CAAs) rather than full-blown eSimulations. cpr.heart.org
Hands-on skills session: After completing the online portion, learners must attend an in-person or simulation-based session to demonstrate psychomotor skills. cpr.heart.org+2cpr.heart.org+2
Consistent learning outcomes: The learning objectives align with those in traditional instructor-led courses, so students receive the same foundational knowledge and skills. cpr.heart.org+1
Flexibility & efficiency: Because much of the instruction is online, organizations and learners gain flexibility in scheduling and resource use. RQI Partners, LLC+1
Certification / eCard: Upon successful completion of both the online and hands-on portions, learners receive an AHA provider card (often an eCard) valid for two years.

When should I start CPR, and how do I know someone needs it?

If a person is unresponsive, not breathing, or breathing abnormally (gasps), you should start CPR.
Don’t waste time trying to find a pulse—lay rescuers are discouraged from extended pulse checks; start compressions promptly. Sarver Heart Center+2Mayo Clinic+2
The “Chain of Survival” emphasizes early recognition, early CPR, early defibrillation, and early advanced support. Wikipedia

What is the difference between CPR, BLS, ACLS, and PALS?

CPR (Cardiopulmonary Resuscitation) is the basic life-saving technique of chest compressions (and sometimes rescue breaths) used when someone’s heart stops.
BLS (Basic Life Support) builds on CPR and is for healthcare providers: it includes use of an AED, two-rescuer CPR, and airway management.
ACLS (Advanced Cardiovascular Life Support) is more advanced, covering arrhythmia recognition, pharmacology, advanced airway, and team leadership during cardiac emergencies in adults.
PALS (Pediatric Advanced Life Support) is similar to ACLS but focused on infants and children — including pediatric rhythms, pediatric dosing, pediatric airway, and shock/respiratory failure in children.

Who needs to be certified in BLS, ACLS, or PALS?

BLS is generally required for most healthcare providers (nurses, EMTs, paramedics, medical assistants) and often is a prerequisite to more advanced courses.
ACLS is required for those working in adult critical care, emergency departments, ICUs, or any setting that deals with adult cardiac emergencies.
PALS is required for those working in pediatrics, pediatric ICUs, ERs, or any environment where you might treat critically ill children.

According to Everything Nurses Need to Know About ACLS, BLS & PALS, “The Basic Life Support (BLS) certification is required for all registered nurses. Advanced Cardiovascular Life Support (ACLS) is required for RNs working in the ICU or with adults. Pediatric Advanced Life Support (PALS) is required for RNs working with pediatric patients.” Nurse.org

What’s the success rate of CPR in real life?

Survival rates vary, but out-of-hospital cardiac arrest survival is about 10% on average.
However, immediate bystander CPR can double or triple survival chances.
High-quality chest compressions and early AED use are the most important factors.

How does CPR work to help someone in cardiac arrest?

Cardiopulmonary resuscitation (CPR) keeps blood and oxygen flowing through the body when the heart stops beating. Chest compressions manually pump the heart, moving oxygen-rich blood to the brain and vital organs. Rescue breaths (or ventilations) add oxygen to the lungs, which then circulates with each compression.

While CPR does not restart the heart, it buys precious time by keeping the brain alive until advanced care (like defibrillation or medications) can restore a normal heartbeat. Without CPR, brain damage can begin in as little as 4–6 minutes.
