  • 2.Apply a simple stop-and-escalate rule.
  • 3.Communicate an escalation clearly and with the right urgency.
🎯

Purpose

Most cardiac emergencies announce themselves with recognizable warning signs. Your job is to catch them early and move fast — escalation is not a last resort, it’s the right first move when a red flag appears.

🚩

Red flags — escalate now

  • •Chest pain/pressure that is ongoing, severe, or with sweating, nausea, or shortness of breath.
  • •Severe or sudden shortness of breath, or inability to speak in full sentences.
  • •Fainting (syncope), especially with exertion or no warning.
  • •Palpitations with chest pain, lightheadedness, or near-fainting.
  • •One-sided weakness, facial droop, or slurred speech (stroke).
  • •Very high or very low blood pressure with symptoms; signs of poor perfusion (cold, clammy, confused).

Stop and escalate

If a patient has any of these, do not work through the rest of your questions first. Get the provider now, and for severe or unstable symptoms direct the patient to call 911 / go to the ED.

🧭

The simple rule

  1. 1.Recognize the red flag.
  2. 2.Decide urgency: emergency (911/ED) vs. urgent (provider now) vs. same-day.
  3. 3.Act: route the patient and notify the provider with a clear ask.
  4. 4.Document what you saw and did.

How to escalate clearly

  • •Say who the patient is and what’s happening right now.
  • •Give one line of relevant history.
  • •State your concern: "I’m worried about ___."
  • •Make the ask explicit: "I need you to talk to them now."
⏱️

When to escalate urgently vs. emergently

  • •Emergent (911/ED): active severe chest pain, severe dyspnea, syncope, stroke signs, unstable vitals.
  • •Urgent (provider now): concerning but stable symptoms that shouldn’t wait for routine callback.
  • •Same-day/routine: mild, stable, non–red-flag concerns per protocol.
🗣️

Spanish phrase

If your chest pain comes back or gets worse, call 911 right away.

Si el dolor de pecho regresa o empeora, llame al 911 de inmediato.

see el doh-LOR deh PEH-cho reh-GREH-sah oh em-peh-OH-rah, YAH-meh al noo-EH-veh OO-noh OO-noh deh een-meh-DYAH-toh

Mini case

A patient calls with chest pressure for the last 20 minutes, now sweaty and a little short of breath.

What do you do?

Show answer

This is an emergency red flag. Direct them to call 911 / go to the ED now, notify the provider immediately, and document. Don’t finish a long symptom questionnaire first.

Checklist

  • I can name the cardiac red flags from memory.
  • I know the difference between emergent, urgent, and routine.
  • I escalate on recognition, not after exhausting my questions.
