Trust your instincts. If you feel something is wrong with your patient, activate the rapid response team. Studies show nurses often sense deterioration 6–8 hours before vital signs fully reflect it. You are the patient's last line of defense.
When to Activate the Rapid Response Team
Call RRT for ANY of the following (varies slightly by institution):
| Parameter | Threshold |
|---|
| Heart rate | <40 or >130 bpm |
| Respiratory rate | <8 or >28 breaths/min |
| SpO2 | <90% on room air; not responding to supplemental O2 |
| Systolic blood pressure | <90 mmHg |
| Level of consciousness | Acute change (confusion, agitation, unresponsive) |
| Urine output | <50 mL over 4 hours (<0.5 mL/kg/hr) |
| Acute chest pain | Any unrelieved or new chest pain |
| Nurse concern | "Something is just not right" — gut feeling is VALID |
Don't wait for all parameters to be met. Partial deterioration + nursing instinct = good enough reason to call. It is always better to over-call than to under-call.
Early Warning Signs of Patient Deterioration
The 6 Signs Most Often Missed
- Subtle behavior change: "He's just not himself today" — family and nurses often notice this first
- Mild respiratory rate increase: RR of 22 when baseline is 14 — easy to dismiss; often first sign of sepsis
- Skin changes: Mottling, pallor, diaphoresis disproportionate to activity
- Restlessness/agitation in a previously calm patient: Often hypoxia before SpO2 drops
- Declining urine output: Starts hours before hypotension in many shock states
- Worsening labs over the shift: Trending creatinine, rising lactate, worsening anion gap
NEWS2 Score (National Early Warning Score)
Many hospitals use NEWS2 to standardize deterioration risk:
| Parameter | Score 3 | Score 2 | Score 1 | Score 0 |
|---|
| RR | ≤8 or ≥25 | 21–24 | 9–11 | 12–20 |
| SpO2 | ≤91% | 92–93% | 94–95% | ≥96% |
| HR | ≤40 or ≥131 | 111–130 or 41–50 | 51–90 or 91–110 | 91–110 |
| SBP | ≤90 | 91–100 | 101–110 | 111–219 |
| Temp | ≤35°C | — | 35.1–36.0 or 38.1–39.0 | 36.1–38.0 |
| LOC | Any change | — | — | Alert |
NEWS2 ≥7 = emergency response; 5–6 = urgent review; 1–4 = increased monitoring.
SBAR Communication for RRT Call
Use SBAR to communicate clearly, concisely, and completely when activating RRT:
| Letter | Content | Example |
|---|
| Situation | What is happening right now? | "This is Nurse Maria on 4 North. I'm calling RRT for Mr. Johnson in room 412 — he has acute respiratory distress." |
| Background | Relevant history & reason for admission | "He's a 68-year-old male, POD 2 after a right hip replacement. No history of respiratory issues." |
| Assessment | Your clinical assessment | "His SpO2 dropped to 88% on room air, RR is 28, he's diaphoretic and confused. I'm concerned about PE or fluid overload." |
| Recommendation | What you need | "I need you at the bedside now. I've placed him on 4L NC — SpO2 is 92%. He needs to be seen immediately." |
RRT Team Members & Roles
- RRT RN (charge nurse/supervisor): Leads the response; additional assessment; helps floor nurse escalate
- MD/ACNP/PA: Orders diagnostics and interventions; decides if transfer to ICU needed
- Respiratory Therapist: Manages airway/ventilation; ABG; BiPAP/CPAP
- Bedside nurse: Gives full report; executes orders; knows the patient best
- Charge nurse: Facilitates logistics; coordinates ICU transfer if needed
Immediate Nursing Actions Before RRT Arrives
- Stay with the patient; do NOT leave
- Apply supplemental O2 immediately (NC 2–4L or NRB if severe)
- Obtain full set of vital signs: HR, BP, RR, SpO2, temp, blood glucose
- Ensure IV access patent; have normal saline available
- Perform focused assessment: neuro (AVPU/GCS), respiratory (work of breathing, breath sounds), cardiovascular (cap refill, pulse quality)
- Pull chart: review recent labs, medications, allergy list
- 12-lead EKG if chest pain or new arrhythmia on telemetry
- Document your findings and time of RRT activation
- Notify attending or covering MD after calling RRT (per protocol)
Preventing Escalation to Code Blue
Every 5 minutes of delay in treating a deteriorating patient statistically increases mortality. Early RRT activation has been shown to reduce code blue rates by 17–65% in hospitals with mature rapid response systems.
Common Reasons Nurses Delay Calling RRT (and why they're wrong)
| Common Hesitation | The Reality |
|---|
| "The doctor already knows about this" | Doctors manage dozens of patients; deterioration may have occurred after last update. Always notify of acute change. |
| "I don't want to seem like I'm overreacting" | Your license and your patient's life outweigh any social awkwardness. The RRT exists to be called. |
| "His vitals are technically in normal range" | Trending is what matters. A creatinine going from 0.9 to 1.8 is significant even if both are "normal." |
| "I'll wait to see if it improves" | Watchful waiting during early deterioration is the most common precursor to preventable codes. |
NCLEX High-Yield Points
- RRT is for deteriorating but NOT yet arrested patients — code blue is for arrest
- Trust your nursing instinct — "something is wrong" is a valid reason to activate RRT
- SBAR: Situation → Background → Assessment → Recommendation
- First nursing action for any deteriorating patient: apply O2, stay at bedside, call for help
- SpO2 <90%, RR >28, HR <40 or >130, SBP <90 are all standard RRT triggers
- Early activation prevents code blue — it is better to over-call than under-call
