Cardiac arrest requires a rapid, highly coordinated team response that goes beyond basic cardiopulmonary resuscitation (CPR). Standard, sequential CPR often fails due to delays and inefficiencies. A high-performance resuscitation team overcomes these limitations by implementing a structured, simultaneous approach to patient care. This system relies on clearly defined roles, known as the Resuscitation Triangle, to maximize efficiency and ensure every life-saving task is executed without delay.
Principles of High-Performance Resuscitation
The success of the Resuscitation Triangle model rests on foundational concepts that transform individuals into a unified team. The most important principle is the immediate assignment of specific roles to every arriving team member to eliminate confusion and hesitation. This ensures that all necessary interventions begin concurrently, rather than sequentially.
Another fundamental concept is closed-loop communication, where a team member repeats an instruction back to the Team Leader to confirm receipt and understanding. This mechanism reduces errors and ensures tasks are completed as directed. The overarching goal of this structured teamwork is to maximize the Chest Compression Fraction (CCF), which is the percentage of time spent actively performing chest compressions. High-performance teams aim for a CCF of 80% or greater to ensure continuous, adequate blood flow.
The Three Hands-On Roles
The Resuscitation Triangle is composed of three hands-on positions that actively deliver patient care. Each role has a distinct, time-sensitive primary objective that must be maintained with high quality throughout the event.
The Compressor
The Compressor provides high-quality, uninterrupted chest compressions to manually pump blood. This involves pushing hard and fast on the center of the chest at a rate between 100 and 120 compressions per minute and to a depth of 2 to 2.4 inches in adults. Full chest wall recoil must be permitted after each compression to allow the heart to refill with blood.
Because high-quality compressions are physically demanding and quickly lead to fatigue, the Compressor must rotate roles with another team member every two minutes, or after five cycles of CPR. This pre-emptive rotation ensures the quality of compressions remains high throughout the resuscitation attempt.
The Airway/Ventilation Manager
The Airway/Ventilation Manager maintains a patent airway and ensures effective oxygen delivery. This person stands at the head of the patient and uses techniques like a bag-valve mask (BVM) to provide ventilations. When an advanced airway is not yet in place, the Airway Manager coordinates ventilations with the Compressor, typically providing two breaths after every 30 compressions.
When an advanced airway is inserted, ventilations transition to a continuous rate of one breath every 6 seconds (10 breaths per minute), while compressions continue without pause. This coordination is essential to prevent excessive ventilation, which can increase pressure in the chest and decrease blood return to the heart.
The Monitor/Defibrillator Operator
The Monitor/Defibrillator Operator manages cardiac monitoring equipment and is responsible for prompt rhythm analysis and defibrillation when indicated. This team member attaches the monitoring pads and positions the screen so the Team Leader can easily view the patient’s heart rhythm. They must be prepared to charge the defibrillator and deliver a shock immediately following rhythm analysis if a shockable rhythm is present.
This role often handles obtaining vascular access, such as establishing an intravenous (IV) or intraosseous (IO) line for medication administration, or delegates this task to another team member. The Monitor/Defibrillator Operator typically switches with the Compressor every two minutes, taking over compressions after the rhythm check to maintain the flow of care.
The Central Coordination Role
The Team Leader occupies the Central Coordination Role, which involves decision-making and oversight rather than direct, continuous hands-on patient care. This person is the “conductor” of the resuscitation effort, ideally standing back from the patient to maintain a clear view of the entire scene and all team members.
The Team Leader’s first duty is to assign all other roles immediately upon the start of the event, ensuring every task is covered. They are responsible for making all treatment decisions, including interpreting rhythm changes and determining which medications to administer based on established protocols.
Effective time management is a primary function of this role, as the leader must actively manage the resuscitation timeline, often with the help of a timekeeper or recorder. This includes calling for the 2-minute compression cycle rotations and ensuring medication administration aligns with clinical guidelines. The Team Leader must use clear, concise language and closed-loop communication to delegate tasks and confirm completion.
The leader maintains situational awareness, constantly evaluating the quality of CPR, the patient’s response, and adherence to Advanced Life Support (ALS) protocols. They are also prepared to step in and assume the duties of any unassigned role, or provide coaching to a struggling team member.
