PALS stands for Pediatric Advanced Life Support. It's an American Heart Association course designed for healthcare providers who respond to emergencies involving infants and children — and it's not a casual credential. You'll leave knowing how to assess a critically ill child, recognize life-threatening conditions before they deteriorate, and execute resuscitation algorithms under pressure.
The AHA developed PALS alongside its sister certifications — BLS (Basic Life Support) and ACLS (Advanced Cardiac Life Support). Each one targets a different patient population and skill level. PALS is specifically for the pediatric patient, from newborns through adolescence, and the protocols reflect how differently kids respond to cardiac and respiratory emergencies compared to adults.
Here's the core reality: children don't die from cardiac causes the way adults do. Pediatric cardiac arrest is usually the end result of respiratory failure or shock — not a sudden heart event. That changes everything about the approach. PALS teaches you to catch the problem upstream, before arrest happens.
Most healthcare employers require PALS for any role that puts you in front of critically ill children. The list is longer than you might expect.
Pediatric nurses — obviously. But also ED nurses who see kids in the mix of general adult volume. ICU nurses. NICU and PICU staff. Pediatricians and family medicine physicians. Paramedics and advanced EMTs. Respiratory therapists working in pediatric or mixed units. Flight nurses and transport teams. Anesthesiologists and CRNAs who cover pediatric surgical cases.
Some outpatient roles require it too — urgent care centers, school-based health programs, and pediatric dentistry offices with sedation protocols have started mandating PALS for clinical staff. If your license puts you anywhere near a pediatric resuscitation, your employer almost certainly wants this card in your wallet.
Check your job description carefully. A lot of RN postings list PALS as preferred on day one but required within 90 days of hire. Don't wait — get it before you start.
These three AHA certifications get lumped together constantly, but they serve distinct purposes. You need to understand where each one fits.
BLS is the foundation. It covers CPR, AED use, and basic airway management for all ages. Every clinical staff member needs it — it's the floor, not the ceiling. BLS doesn't touch advanced algorithms, drug dosing, or systematic assessment.
ACLS builds on BLS for adult patients. Cardiac rhythms, IV/IO access, advanced airway management, team dynamics, and arrest algorithms for adults. If you work in an adult ED, ICU, or cardiac unit, ACLS is your credential.
PALS is the pediatric counterpart to ACLS. Same concept — advanced resuscitation — but completely rebuilt for children. The assessment approach is different (TICLS, the Pediatric Assessment Triangle), the drug doses are weight-based, the respiratory failure categories are pediatric-specific, and the shock recognition criteria differ meaningfully from adults.
Many providers hold all three. An ED nurse covering both adult and pediatric bays, for instance, typically needs BLS + ACLS + PALS. A pediatric ICU nurse might skip ACLS entirely and focus on BLS + PALS instead.
Don't confuse PALS with NRP (Neonatal Resuscitation Program), either. NRP is for newborns in delivery settings — PALS covers infants through adolescents in medical and trauma contexts.
The AHA's PALS curriculum is organized around a systematic approach to sick kids. You're not just memorizing algorithms — you're building a clinical decision framework that works even when a child is crashing in front of you and the room is chaos.
The course hits these major content areas:
The Pediatric Assessment Triangle (PAT): A rapid visual tool — appearance, work of breathing, circulation to skin — that lets you categorize severity from across the room before you even touch the patient. TICLS gives you the appearance component: Tone, Interactivity, Consolability, Look/gaze, Speech/cry.
Systematic Pediatric Assessment: Primary and secondary surveys in sequence. This is where SAMPLE history, vital signs by age group, and the ABCDE approach come in. You need to know normal ranges cold — a heart rate of 140 is normal in a toddler and alarming in a 10-year-old. Take a solid pass through pediatric systematic assessment practice before your course date.
Respiratory Emergencies: PALS breaks respiratory problems into four categories — upper airway obstruction, lower airway obstruction, lung tissue disease, and disordered control of breathing. Treatment differs for each. The BVM technique for infants, proper jaw thrust without head tilt in trauma, CPAP vs. intubation decisions — it's all in here. Brushing up on PALS respiratory emergencies practice is worth your time.
Shock Recognition and Management: Hypovolemic, distributive (septic, anaphylactic, neurogenic), obstructive, and cardiogenic shock all present differently in kids and require different interventions. Fluid bolus dosing (20 mL/kg in most cases), vasopressor choices, and recognizing when fluid is making things worse — all tested.
Cardiac Arrest Algorithms: Shockable vs. non-shockable rhythms. Pediatric defibrillation doses (2 J/kg initial, 4 J/kg subsequent). Epinephrine dosing (0.01 mg/kg IV/IO). The pulseless arrest algorithm, the bradycardia with pulse algorithm, and the tachycardia algorithms. These are not optional memorization — the megacode scenario tests your ability to lead a team through them. Work through some PALS cardiac arrest questions to get comfortable with the decision points.
Tachycardia Management: Narrow-complex vs. wide-complex, stable vs. unstable. Synchronized cardioversion energy dosing (0.5–1 J/kg). Adenosine dosing for SVT. The PALS tachycardia practice questions will show you exactly where this tends to trip people up on the written exam.
Post-Resuscitation Care: What happens after ROSC (return of spontaneous circulation). Target temperature management, avoiding hyperthermia, glucose management, avoiding hyperoxia — the post-arrest period determines long-term neurologic outcome, and the AHA has strong recommendations here.
There are two components to PALS completion: a written exam and a skills evaluation.
The written exam is 30 questions. You need to answer at least 25 correctly — that's 84% — to pass. Questions focus on recognition (what rhythm is this? what category of respiratory distress?), intervention (what's the correct defibrillation dose?), and algorithm sequencing (what comes next in this arrest scenario?). Most people who've done the pre-course work find it manageable. It's the rhythm strips and the drug dose math that catch people off guard.
The skills evaluation includes megacode scenarios — you'll lead a simulated resuscitation with mannequins and an instructor playing team member roles. You'll also demonstrate rhythm recognition, effective CPR technique, and correct AED or manual defibrillation. There's no single massive megacode that tests everything at once; different scenarios cover different algorithm branches.
You can remediate on the day if you don't pass a skills station on the first try. Most instructors give you one or two more attempts before you'd need to reschedule.
The AHA authorizes PALS through a network of Training Centers — hospitals, community colleges, fire departments, and independent training organizations. You can find one at the AHA's website using the course finder. Most major hospital systems run their own training centers and offer courses to staff (sometimes free, sometimes subsidized).
Blended learning is now standard. You complete the online HeartCode PALS module at home — typically 8–10 hours of video, case studies, and online testing — then attend an in-person skills day at a Training Center for the megacode and skills checkoff. The skills day runs around 4–6 hours.
Traditional classroom-only courses still exist, usually as 2-day formats. Some people prefer the hands-on immersion. Both formats produce the same AHA PALS provider card — there's no distinction on the credential itself. One thing worth knowing: independent training centers sometimes schedule weekend skills days, which is useful if you work a standard weekday hospital schedule and can't easily take time off for a 2-day classroom course.
Cost runs between $150 and $300 depending on the training center and format. HeartCode PALS (the online component) costs around $100–$125 from the AHA directly; skills days at independent training centers add another $75–$150. If your hospital is paying for it, you'll often get the full blended course for nothing out of pocket.
Your card is valid for two years from the date of completion.
PALS renewal courses are shorter — roughly 7 hours total, or a condensed HeartCode online module plus a skills day. The written exam is still 30 questions with an 84% pass requirement. Megacode and rhythm recognition stations remain.
What's different is the assumed knowledge level. Renewal courses move faster through the content because you're expected to have maintained familiarity with the algorithms. If you've been practicing in a pediatric or mixed setting, renewal usually feels easier than the initial course. If you haven't used the algorithms regularly — maybe you transferred to a less acute unit — give yourself extra review time. The skills stations don't care how long it's been; they only care whether you can lead a megacode correctly.
Don't let your card lapse. Once it expires, you have to retake the full initial course — not renewal. Most employers won't let you work past expiration; some HR systems auto-flag credentials and pull you from scheduling. Two years goes faster than it sounds.
The people who struggle with PALS aren't the ones who don't know the material — they're the ones who tried to cram algorithms the night before without building any underlying rhythm recognition skill. Don't do that.
Start with the algorithms. Print the AHA PALS algorithms and tape them somewhere you'll see them daily for two weeks before the course. The pulseless arrest algorithm, the bradycardia algorithm, the two tachycardia pathways — know them cold before you walk in. The course builds on them; it won't teach them from scratch.
Practice rhythm strips until identification is automatic. Sinus tach, SVT, VT with pulse, VF, asystole, PEA — you need to call these in seconds, under pressure, with a mannequin on the floor. Flashcards work. Online rhythm drill tools work. Sitting with an EKG textbook does not.
Know your weight-based doses cold. Epinephrine is 0.01 mg/kg (1:10,000) IV/IO. Adenosine for SVT starts at 0.1 mg/kg (max 6 mg first dose). Defibrillation starts at 2 J/kg. These numbers come up in written questions and megacode scenarios — instructors are watching whether you call them out correctly while leading the team.
Do the pre-course self-assessment. HeartCode includes pre-tests that show you exactly where your knowledge gaps are before you start the full module. Take them seriously — don't skip to the answer key.
The megacode is where people get nervous. You're standing in front of an instructor, calling out orders, checking pulses, directing compressions. It feels like a performance. Lead clearly, say your reasoning out loud, and don't freeze on a number you're unsure about — call it out as a question to your team if needed. That's actually good team dynamics, and instructors recognize it.
Short answer: yes, if pediatric patients are anywhere in your career trajectory.
PALS opens doors. Pediatric transport teams, flight programs, travel nursing contracts in pediatric hospitals — most of these list PALS as required, not preferred. Having it before you apply puts you ahead of candidates who'd need a few months to acquire it.
It's also genuinely useful knowledge. The systematic assessment approach — PAT, TICLS, primary survey, ABCDE — is a framework you'll use every time you're in front of a sick child regardless of setting. Most providers who complete PALS say they felt more confident managing pediatric emergencies in their day-to-day work, not just in formal resuscitation scenarios.
If you're a nurse in a mixed adult-pediatric ED and you haven't taken PALS yet, there's really no good reason to wait. Get certified, then use our PALS practice test to keep your knowledge sharp between renewals.
The certification itself is straightforward once you commit to the preparation. Most people who fail do so not because the material is too difficult — but because they underestimated how much active recall the megacode requires. Don't be that person. Prepare methodically, start early, and treat the skills practice as seriously as the written content.
Two weeks out, your preparation should shift from passive reading to active recall. Draw the pulseless arrest algorithm from memory on a blank sheet. Can't do it? That's fine — you've got time. But the goal is to reproduce the key decision points without looking at a reference card. Confident team leaders who know their algorithms earn sign-off faster.
Run through pediatric vital sign ranges by age group daily. The difference between a normal heart rate for a 2-month-old versus a 5-year-old versus a 12-year-old is clinically significant — and written exam questions exploit exactly that kind of age-specific knowledge. Write them out from memory.
Review your pediatric drug dosing the evening before. Not to memorize everything from scratch — just to refresh the key numbers. Epinephrine, adenosine, amiodarone, atropine, cardioversion energy. The megacode doesn't give you a Broselow reference. Know your doses.
Most of all — show up rested. The course is cognitively demanding, the scenarios are stressful, and tired brains don't perform well under simulated emergency conditions. Treat the course day like a real exam, not an afterthought.
Basic Life Support is the required baseline for all clinical staff. It covers high-quality CPR for adults, children, and infants; AED use; and basic airway management. BLS doesn't include advanced airway management, cardiac rhythm interpretation, or IV/IO drug administration. Every nurse, physician, and paramedic needs BLS — it's a prerequisite for both ACLS and PALS.
Advanced Cardiac Life Support builds on BLS for adult patients. Covers cardiac rhythm recognition, IV/IO access, advanced airway management (including intubation), adult arrest algorithms, and team dynamics. ACLS is required for most adult ICU, ED, cardiac, and telemetry roles. It doesn't cover pediatric-specific protocols or weight-based dosing.
Pediatric Advanced Life Support is the pediatric counterpart to ACLS. Covers systematic pediatric assessment (PAT, TICLS), respiratory emergency categories, weight-based drug dosing, pediatric shock recognition, and cardiac arrest algorithms for infants and children. Required for pediatric nurses, pediatric ICU/ED staff, flight nurses, and transport teams.
0.01 mg/kg IV/IO (1:10,000 concentration). Max 1 mg per dose. Given every 3–5 minutes during pulseless arrest.
0.1 mg/kg IV/IO rapid push (max 6 mg first dose). Second dose: 0.2 mg/kg (max 12 mg). Requires rapid saline flush.
5 mg/kg IV/IO for VF/pVT during pulseless arrest. Can repeat up to 15 mg/kg/day. Also used for stable wide-complex tachycardia.
Initial shock: 2 J/kg. Subsequent shocks: 4 J/kg (and may increase up to 10 J/kg for refractory VF/pVT).
0.5–1 J/kg for unstable SVT or unstable wide-complex tachycardia. If ineffective, increase to 2 J/kg.
0.02 mg/kg IV/IO. Minimum dose 0.1 mg, maximum 0.5 mg per dose. For symptomatic bradycardia with pulse when vagal tone is the suspected cause.
