Calling a code
Formal Definition
The act of activating the institutional cardiopulmonary arrest / resuscitation response (often called a "code blue" or equivalent) — announcing or paging the medical response team to a specific location for an unresponsive, pulseless, or critically unstable patient; involves identifying the patient, location, and clinical status, communicating clearly to the page operator, and initiating basic resuscitation (CPR, defibrillation if shockable rhythm, airway management) before the team arrives when the situation demands.
How It's Used on the Ward
"Calling the code" or "code blue called" — when a patient is found unresponsive or pulseless, the first responder activates the institutional rapid response by calling the operator or pressing the code button; the entire resuscitation team (typically ICU MD/RN, respiratory therapy, anesthesia, sometimes cardiology) responds within minutes; the announcement overhead often is "code blue, [location], [location]" repeated.
Example
""Floor nurse finds 78-year-old patient unresponsive in bed, no pulse, calls for help. Within 90 seconds: chest compressions started, defibrillator pads placed, code blue called via overhead page. "CODE BLUE, 7 EAST, ROOM 714, CODE BLUE 7 EAST ROOM 714." Resuscitation team arrives within 4 minutes. Rhythm on monitor: ventricular fibrillation. 200J shock delivered. Patient converts to sinus rhythm with ROSC after 8 minutes of CPR.""
Clinical Context
When to call a code: patient unresponsive, not breathing normally (or only gasping), no pulse within 10 seconds of palpation. Hesitating to call because "we're not sure" is the wrong instinct — the dispatcher activates the team based on the assessment provided, and the team can downgrade the response if the patient is found stable. Resuscitation sequence: (1) Call for help, (2) Begin CPR, (3) Attach defibrillator / pads, (4) Analyze rhythm — shock if VF/pulseless VT, (5) Resume CPR immediately, (6) IV/IO access, epinephrine 1mg q3-5min, (7) Airway management, (8) Identify and treat reversible causes (Hs and Ts). Calling a code does not mean the patient is DNR/DNI by default — DNR must be established in advance and documented; if no code status is documented, the patient is full code and must be resuscitated. Teams often practice "slow code" with family present which is medically and ethically fraught — full code or comfort care based on patient wishes, never a half-effort.
