The emergency is happening. You are the first person there.
8 scenarios. One protocol: Observe, Decide, Call, Act. The four-line clinician script, the Four Numbers reflex, and every Threshold Line signed by a board-certified ER physician.
I wrote this for the moment
before the ambulance arrives.
Volume 1 gave the household the reflexes. Volume 2 gave the household the pantry. Volume 3 gives the household the protocol for the moments when the decision is not whether to act — it is how. Eight scenarios, one protocol, and a board-certified ER physician who co-signed every Threshold Line in this volume. His signature is the Library's way of saying: this is the call an ER doctor would make at intake.
The household is not nothing. The household sees the patient first, longest, and most often. This guide gives the household the words to describe what it sees — and the line that says when to stop describing and call 911.
License numbers published in the guide. Every Threshold Line carries L.G.N.'s second signature — board-certified Emergency Medicine physician. Updates free, forever.
9 Chapters. 3 Parts.
One protocol that runs eight ways.
Every scenario follows the same four steps — Observe, Decide, Call, Act — so the household runs the protocol once and knows it for all eight emergencies.
🌡️ Fever Spike
Fever is not the enemy — it is the body running a defense. The chapter teaches the household to watch the child, not chase the number. Weight-based dose tables, the Three Months threshold, and the one sentence that ends every action page.
- Green/Yellow/Red by age band — under 3 months is always Red
- Antipyretic dose tables reviewed by ESP, PharmD · KMP, MD
- Febrile seizure protocol — when to observe, when to call 911
🔥 Kitchen Burn
Cool running water, 15-25°C, 20 minutes uninterrupted. Not ice, not butter, not toothpaste. The Cochrane 2020 evidence base. Burn depth recognition and American Burn Association referral criteria on the Action page.
- Depth recognition: superficial, partial-thickness, full-thickness
- Burn Center referral criteria — when the family car is not the answer
- Threshold Line signed by LGN, EM-MD
🏥 The ER Decision
911, urgent care, or clinician callback. The three-column decision card. FAST stroke recognition. The dispatcher is the household's triage partner — when in doubt, call 911 and let the dispatcher lead.
- Three-column card: Callback / Urgent care / 911 with specific criteria
- FAST stroke recognition and anaphylaxis criteria
- Threshold Line signed by LGN, EM-MD and DRS, MD
🤕 Child Fall
The PECARN decision rule adapted for household use. Two age tracks: under 2 and 2 and older. Six observable signs. The child with none of them watches at home for 24 hours. The child with any of them calls the clinician today.
- PECARN checklist — both age tracks on the Action page
- 24-hour home observation protocol with hourly checkpoints
- Suspected spinal injury: do not move — call 911
🤢 Food Poisoning
The risk is fluid loss, not the vomiting. The WHO oral rehydration solution recipe. The half-teaspoon rule. Three signs of clinical dehydration — any two together is a call. Reviewed by MHG, RDN and AJK, CNM.
- ORS recipe from WHO/UNICEF · reviewed by MHG, RDN
- Three dehydration signs — any two is a clinician call
- No honey under 12 months — infant botulism cross-reference

Answers to the questions households ask before they buy.
Is this a substitute for calling 911 or my doctor?
No — and the guide is explicit on every page. The disclaimer is on page one: if a household member is in an active emergency right now, the household calls 911 first and uses this guide afterward. Every Action page ends with the Threshold Line — the specific signs that mean stop home care and call 911 or the clinician now. The Threshold Line was co-signed by L.G.N., a board-certified Emergency Medicine physician, on every chapter in this volume.
What is the four-line clinician script?
It is based on SBAR — Situation, Background, Assessment, Recommendation — the standardized handoff protocol used between clinicians. The guide adapts it into four lines a household can run cold: who, what, the Four Numbers, and what you have done. The script is pre-filled for each scenario in the Lookup section. The household that calls with four numbers and a prepared script gets a faster, more accurate callback than the household that calls with adjectives.
What are the Four Numbers?
Temperature, respiratory rate, heart rate, and oxygen saturation. Normal ranges vary by age and are printed in every Lookup section. A pulse oximeter for oxygen saturation costs $15–$25 at any pharmacy and is listed in the cabinet inventory in Chapter 9. The household that already owns Volume 1 (Family Field Guide) has the Four Numbers reflex from that volume; Volume 3 builds on it.
Why does an ER physician sign every Threshold Line?
Volume 3 is the volume of escalation decisions — whether to handle at home, call the clinician, or go to the ER. L.G.N. is a board-certified Emergency Medicine physician who makes these triage calls professionally. The Library's policy is that the household reading this guide is making a call that an ER doctor would otherwise make at intake. L.G.N.'s second signature on every Threshold Line is the Library's way of acknowledging that weight.
Do I need Volume 1 to use this guide?
No. Volume 3 is complete as a standalone guide. The Four Numbers reflex and the Green/Yellow/Red Safety Filter are both introduced in this volume for readers new to the Library. A household holding Volume 3 alone has the full protocol. A household holding Volume 1 and Volume 3 together has a deeper read — the cross-references are explicit in the text.
What format is it and do I need to print it?
It is a single PDF, instant download, fully readable on a phone, tablet, or laptop. The guide is designed to be read three times: once quietly at the kitchen table, once after a near-event, and once during the event with the Lookup section open. The 8 Decision Cards Binder Kit is meant to be printed and posted. Printing is optional; the cards are the point.
What is the refund policy?
14-day no-questions-asked refund. If the guide does not deliver what we promise, email us within 14 days and we will refund you in full. You keep the PDF. We honor refunds without friction.
