A BLS class teaches basic life support skills required for healthcare workers and many emergency responders. BLS (Basic Life Support) certification covers high-quality CPR for adults, children, and infants; use of AEDs (automated external defibrillators); team-based resuscitation; and managing choking emergencies. The American Heart Association (AHA) is the primary BLS provider, but Red Cross and others offer similar training accepted by many employers.
Who needs BLS. Healthcare workers: nurses, doctors, EMTs, paramedics, pharmacists, dentists, dental hygienists, medical assistants, lab technicians. Many healthcare-adjacent roles: respiratory therapists, physical therapists, occupational therapists, social workers in clinical settings. Emergency responders: police, firefighters. Workplace safety: lifeguards, daycare workers, school nurses. Required for nursing school, medical school, EMT certification.
BLS vs CPR vs ACLS. BLS: comprehensive resuscitation skills, ~4-hour course, healthcare-focused. CPR: basic compression-only or with breaths, ~2-hour course, layperson-focused. ACLS (Advanced Cardiac Life Support): advanced rhythm interpretation, drug administration; ~2-day course; for ICU, ED, advanced practice clinicians. BLS is foundation for all higher-level training.
Common BLS scenarios. Hospital code blue. ICU patient cardiac arrest. ER stroke patient. Outpatient clinic emergency. Pre-hospital cardiac arrest (EMTs). Childcare emergency (drowning, choking). Workplace incident.
Why it matters. Cardiac arrest survival depends on rapid CPR and defibrillation. Properly trained workers respond effectively. AHA estimates BLS-trained responders save thousands of lives annually. Hospital cardiac arrest survival rates have improved with widespread BLS training.
This guide covers BLS class content, options for training, costs, online vs in-person, certification process, renewal, and what to expect on the day of class. It's for anyone needing or considering BLS certification.
What you'll learn in a BLS class.
Adult CPR. Recognize sudden cardiac arrest. Activate emergency response system. Perform high-quality chest compressions: depth 2-2.4 inches (5-6 cm), rate 100-120 per minute, allow full chest recoil between compressions, minimize interruptions. Provide effective ventilations (mouth-to-mask or bag-mask): 1 second each, visible chest rise.
Pediatric CPR (1 year to puberty). Adjustments from adult: depth about 1/3 chest diameter (~2 inches), compression-to-ventilation ratio 30:2 (single rescuer) or 15:2 (two rescuer), use AED with pediatric pads if available (under 8 years), can use adult pads if pediatric not available.
Infant CPR (under 1 year). Two-finger technique (single rescuer) or two-thumb-encircling-hands technique (two rescuer). Compress with about 1.5 inches depth. 30:2 ratio (single rescuer) or 15:2 (two rescuer). Mouth-to-nose-and-mouth ventilations. Smaller breaths than adult.
AED use. Turn on AED. Apply pads (specific placement varies by patient size). Follow audio prompts. Ensure no one touches victim during analysis. Deliver shock when prompted (clearly say 'clear' before shocking). Resume compressions immediately after shock.
Team resuscitation. Roles in team: compressor, ventilator, defibrillation specialist, team leader, recorder, IV access (when applicable). Closed-loop communication ('Epinephrine 1 mg given' acknowledged with 'Epi 1 mg received'). Coordinated minute-by-minute rotations during long arrests.
Choking management. Adult: Heimlich maneuver (abdominal thrusts) for conscious adult; back blows alternating with abdominal thrusts for unconscious. Infant: 5 back blows alternating with 5 chest thrusts. Switch to CPR if patient becomes unresponsive.
High-quality CPR principles. Push hard. Push fast. Full chest recoil. Minimize interruptions. Avoid excessive ventilation. Switch compressors every 2 minutes (or earlier if fatigued).
2020 AHA guidelines updates. Compression rate 100-120/min (no longer 'at least 100'). 'CAB' approach (Compressions-Airway-Breathing). Hands-only CPR emphasis for bystanders. Reduced emphasis on pulse check (don't waste time).
Compressions 2-2.4 inches deep, 100-120/min. Ventilations 30:2 ratio.
Smaller depth, 30:2 or 15:2 ratio. AED with pediatric pads if available.
Two-finger or two-thumb technique. 1.5 inches depth. Smaller breaths.
Apply pads, follow prompts, clear before shock, resume compressions.
Defined roles. Closed-loop communication. Compressor rotation every 2 min.
Heimlich for adults; back blows + chest thrusts for infants.

BLS certification and renewal.
Initial certification. Pass written test (84%) and skills check. Receive: AHA BLS Provider eCard (digital) and/or printed certificate. Card includes: name, course completion date, expiration date (2 years), instructor name, signature.
How to verify your eCard. AHA: heart.org/cpr to login and access eCards. Red Cross: certificates available through redcross.org account. Most employers accept digital cards.
Validity period. AHA and Red Cross BLS: 2 years from completion date. Watch expiration carefully — many employers don't allow grace period.
Renewal process. Renewal courses available 60-90 days before expiration. Renewal courses faster than initial (typically 1-2 hours). Cost similar ($50-90). Skills check + written test. Updated to latest guidelines.
If certification lapses. Generally cannot renew expired card. Must take full BLS course again (4-5 hours). Don't let it expire — set calendar reminders 90 days before.
HeartCode BLS Renewal. Online review + virtual skills evaluation. Convenient for currently certified providers. Same renewal price typically.
What's included in renewal. Review of high-quality CPR. Updates to AHA guidelines. AED protocol updates. Team resuscitation refresher. Final skills check. Final written test (typically 10-15 questions for renewal vs 25 for initial).
Employer-specific requirements. Some employers (hospitals especially) require AHA BLS Provider specifically. Verify which course they accept. Some require renewal at exactly 24 months, not 23 or 25.
State-specific. EMT-related: state may require specific BLS course or have state-approved providers. Check your state's EMS regulations. Some healthcare licenses (nursing, advanced practice) have specific BLS requirements.
Multiple cards. Some healthcare workers carry multiple BLS cards (AHA + Red Cross) to satisfy different employer requirements. Inconvenient but sometimes necessary.
Written test 84%+ (typically 25 questions, 21 correct). Skills check on adult/child/infant CPR, AED, choking. Instructor evaluates competency. Most students pass first time.
AHA: digital eCard at heart.org. Red Cross: certificate at redcross.org. Some programs provide printed card. Save digital and physical copies.
Certification valid 24 months from completion. Watch expiration. Most employers don't allow grace period. Set calendar reminder 90 days before.
1-2 hour renewal course before expiration. Faster than initial. HeartCode online + virtual skills option. Cost similar to initial ($50-90).
If expired, retake full BLS class. Most providers don't renew expired cards. Time-cost expensive to let it lapse.
Some employers require AHA specifically. Verify which course they accept BEFORE paying. Some have state-specific requirements.

Common BLS class questions and concerns.
I'm nervous about CPR on manikins. Normal. Everyone feels awkward initially. Instructors expect it. Practice quickly normalizes the experience. By end of class, you'll feel confident.
I have a physical limitation. Some accommodations available. Discuss with instructor in advance. Some skills (especially compressions) may be modified. Confirm acceptability of modified completion with instructor.
I've never done CPR before. That's fine. BLS classes designed for beginners. Instructors will teach from scratch. Hands-on practice cements the skills.
What if I make a mistake in real life. CPR done imperfectly is better than no CPR. Good Samaritan laws protect you in most jurisdictions when acting in good faith. Don't hesitate.
How do I find a class near me. Search heart.org or redcross.org. Check local hospitals. Community colleges and universities. Local fire department.
What's the difference between AHA and Red Cross BLS. Both teach same essential skills. AHA more widely required by healthcare employers. Red Cross more common in general workplace settings. Both accepted by most employers.
Will I forget what I learned. Yes, gradually. That's why renewal every 2 years exists. Many healthcare workers practice mentally and review periodically.
Can I do BLS at home. Studying yes; certifying no. AHA and Red Cross require in-person skills verification. Online-only courses generally not accepted by healthcare employers.
What if I'm pregnant. BLS classes safe for pregnant participants. Modify compressions if needed (different angle). Discuss with instructor.
What if I have a heart condition. Discuss with instructor before class. Avoid prolonged stress. Most can attend with appropriate breaks.
Final thoughts. A BLS class is a 4-5 hour investment that prepares you to save lives. Whether you're a nurse, EMT, physician, or any healthcare worker requiring certification, the skills you learn are immediately applicable and lifelong useful.
Choose your provider carefully. AHA is the gold standard for healthcare. Red Cross is widely accepted. Hospital-sponsored programs are often free for staff. Verify your employer accepts the course you're taking before paying.
Format depends on your situation. In-person works best for first-time learners. HeartCode (online + skills) is convenient for renewing or experienced providers. Both result in the same valid certification.
Prepare for class. Review the AHA BLS Provider Manual. Take practice tests. Memorize key numbers (depth, rate, ratios). Mental practice helps actual performance.
Participate actively in class. Engage with instructors. Practice with all manikins. Ask questions. Make mistakes and learn from them. The classroom is the safe place to develop competency.
Maintain your certification. Set calendar reminders 60-90 days before expiration. Don't let it lapse. Renewal courses are faster and cheaper than starting over.
Use it in real life. BLS-trained responders save thousands of lives annually. When you witness cardiac arrest at work or in community, your training prepares you to act. Confidence comes from preparation and practice.
The BLS class is a small investment with enormous return. Time spent learning these skills could be the difference between life and death for someone someday. Take it seriously, prepare well, and become the person who knows what to do when seconds matter.
