AHA CPR rules: advanced airway means continuous compressions 100–120/min with async ventilation—adults 10/min, pediatrics 20–30/min.
Once an advanced airway is placed during CPR, compress continuously at 100–120/min and ventilate asynchronously (adults 10/min; pediatrics 20–30/min).
According to American Heart Association (AHA) cardiopulmonary resuscitation guidelines, which statement correctly describes compression and ventilation during cardiac arrest?
Apply neonatal resuscitation guidance separately to newborns at birth.
A common exam miss is mixing adult/pediatric AHA BLS/PALS with neonatal resuscitation (NRP), or incorrectly continuing a 30:2 or 15:2 ratio after an advanced airway is secured. The boards often test the pivot point: “advanced airway placed → no pauses for breaths.”
Per AHA 2020 CPR & ECC Guidelines: with an advanced airway during cardiac arrest, provide continuous compressions at 100–120/min and ventilate asynchronously—adults: 1 breath every 6 seconds (10/min); infants/children: 1 breath every 2–3 seconds (20–30/min). Newborns at birth are handled under NRP, where compressions (when indicated) are typically coordinated 3:1 with a target of ~120 events/min (90 compressions + 30 breaths).
| Option | What It Tests / Implies | Why It’s Wrong Here |
|---|---|---|
| Single rescuer | Single-rescuer ratios; attempts to differentiate infant vs child/adult | Single rescuer for infant/child is 30:2, not 15:2 (15:2 is two-rescuer pediatric). |
| Two rescuers | Overgeneralizes pediatric two-rescuer ratio to all ages | Adults without an advanced airway remain 30:2 regardless of rescuer number (AHA BLS). |
| Newborns with an advanced airway receive continuous, unsynchronized compressions at 120 compressions/minute and 1 breath every 3 seconds. | Misapplies post–advanced airway “asynchronous” concept to newborn at birth | NRP uses 3:1 coordinated compressions:ventilations when compressions are indicated; “continuous compressions + q3 sec breaths” is not the NRP standard. |
| With an advanced airway, adults receive 1 breath every 6 seconds, whereas infants and children receive 1 breath every 2–3 seconds; all receive continuous compressions at 100–120/minute without synchronizing breaths to compressions. | Correct AHA advanced-airway ventilation rates by age group | Correct: continuous compressions 100–120/min + asynchronous ventilation (adult 10/min; pediatrics 20–30/min). |
Advanced airway in CPR = continuous compressions + asynchronous ventilation (adult 10/min, pediatrics 20–30/min)—no 30:2 or 15:2 ratio anymore.
The stem’s “apply neonatal guidance separately” is a deliberate trap: the test wants you to keep adult/peds AHA CPR rules straight while not letting NRP’s 3:1 framework contaminate infant/child arrest management outside the delivery room.
An adult is in cardiac arrest. Two rescuers provide BLS with a bag-mask device and no advanced airway. What compression-to-ventilation ratio should they use?
A 4-year-old is pulseless. Two rescuers begin CPR with a bag-mask and no advanced airway. What ratio is recommended?
An intubated adult remains in VF arrest during ACLS. What ventilation strategy is recommended while compressions continue?
A 2-year-old is intubated during CPR for asystole. Which ventilation rate is most appropriate?
A term newborn has HR 40/min despite effective ventilation. Compressions are started and an endotracheal tube is placed. Which compression–ventilation approach is recommended?
How would your ventilation strategy differ between (1) a 6-month-old in out-of-hospital cardiac arrest after drowning once intubated, and (2) a newly delivered term newborn with persistent bradycardia despite effective ventilation?
Q1: When do you stop using 30:2 or 15:2 during CPR?
A: The ABIM/ABEM-style exams expect you to switch to continuous compressions with asynchronous ventilation once an advanced airway is in place (AHA 2020).
Q2: Why is pediatric ventilation faster than adult ventilation with an advanced airway?
A: Boards test that pediatrics generally require higher ventilation rates during CPR with an advanced airway (20–30/min) compared with adults (10/min) per AHA 2020 pediatric vs adult guidance.
Q3: Does intubation change the neonatal (NRP) 3:1 ratio?
A: No—NRP at birth still prioritizes a 3:1 coordinated pattern when compressions are indicated; exams treat neonatal resuscitation as a separate algorithm (AHA/NRP 2020).
Q4: What compression rate should you target during CPR with an advanced airway in adults and pediatrics?
A: 100–120/min with minimal interruptions; ventilation is delivered asynchronously (AHA 2020).
