Medical
Thirty-seven lessons on medical emergencies seen before the hospital, including shock, sepsis, stroke, glucose emergencies, toxicology, and environmental illness. The lessons separate what a paramedic can recognize from treatment that belongs in the hospital.
37 lessons
Each lesson is 15 minutes or less, including a self-check drawn only from that lesson. A passed quiz is saved on this device.
Shock Categories
12 min
Volume, distributive, cardiogenic, or obstructive shock — matching fluids and destination to the category instead of treating every low blood pressure the same.
Start lesson →Sepsis Recognition in the Field
12 min
Infection plus new organ dysfunction or hypoperfusion: screen, pre-notify, fluids per protocol (30 mL/kg is a hospital three-hour target), and qSOFA is not a rule-out.
Start lesson →Stroke Recognition & Last Known Well
12 min
Last known well as last seen normal, a brief stroke screen, glucose, NPO, scene-time discipline, and destination per local endovascular and transfer rules.
Start lesson →Altered Mental Status Framework
12 min
A field AMS framework: glucose, stroke, seizure, toxin, trauma, and infection — treat life threats, then the cause that can be found.
Start lesson →Anaphylaxis Recognition
10 min
Anaphylaxis without waiting for hives: intramuscular epinephrine in the mid-anterolateral thigh, airway and fluids, and why diphenhydramine is not the priority drug.
Start lesson →Diabetic Emergencies: Hypo & Hyper
12 min
Hypoglycemia, DKA, and HHS in the field: check glucose early, D10 versus oral versus glucagon framing, and when “intoxication” is a glucose problem.
Start lesson →Overdose and Toxidromes
12 min
Opioid, sympathomimetic, anticholinergic, cholinergic, and sedative patterns — airway first, antidotes only as authorized, and bringing the containers.
Start lesson →Seizure & Status Epilepticus
12 min
Protect the head, nothing in the mouth, glucose, the five-minute status threshold, IM or IN benzodiazepine if no IV, and Todd’s paralysis as a stroke mimic.
Start lesson →CHF & Pulmonary Edema
12 min
Hypertensive flash pulmonary edema versus COPD: sit the patient up, CPAP if the airway is protected, nitroglycerin if authorized, and no trauma-style fluid boluses.
Start lesson →Syncope in the Field
10 min
A high-risk syncope screen: 12-lead, glucose, cardiac, hemorrhage, and neurologic clues, and why hospital scores do not clear a patient on scene.
Start lesson →Pulmonary Embolism: Field Suspicion
12 min
Sudden dyspnea, hypoxia, or syncope with PE risk: supportive care, 12-lead, and not treating it as simple anxiety or pneumonia. Diagnosis is hospital-based.
Start lesson →Hypertensive Emergency vs High BP
10 min
A high cuff reading versus a failing organ: do not lower asymptomatic hypertension on scene; stroke, ACS, heart failure, and pregnancy own the path.
Start lesson →Heat Stroke vs Heat Exhaustion
12 min
Heat stroke as CNS dysfunction plus hyperthermia: cool immediately, sweat does not rule it out, ice-water immersion when available; antipyretics do not treat it.
Start lesson →Eclampsia & Preeclampsia
12 min
Seizure in pregnancy or up to six weeks postpartum: magnesium first, left lateral or uterine displacement, glucose, and an OB-capable hospital.
Start lesson →GI Bleed in the Field
10 min
Upper versus lower GI bleed clues, shock recognition, airway if the patient vomits blood, TXA only if protocol, and a destination that can endoscope or operate.
Start lesson →Carbon Monoxide in the Field
10 min
Multiple patients, generators, and unreliable pulse oximetry: high-flow oxygen, remove from the source, and pregnant patients as a destination priority.
Start lesson →Accidental Hypothermia (Not Arrest)
10 min
Accidental hypothermia with a pulse: gentle handling, insulation, and not declaring death on a cold patient your protocol says to rewarm.
Start lesson →Dialysis Emergencies
10 min
Missed dialysis: hyperkalemia, volume overload, access-site bleeding, and a destination that can dialyze.
Start lesson →Abdominal Pain Red Flags
10 min
Field red flags in abdominal pain: shock, peritonitis, AAA, ectopic pregnancy, and why gastroenteritis is a dangerous first label.
Start lesson →Severe Agitation in the Field
10 min
De-escalation, glucose and hypoxia, no prone restraint or hobble, and monitoring after sedation — describing severe agitation without “excited delirium” as a diagnosis.
Start lesson →Alcohol Withdrawal in the Field
10 min
Withdrawal versus intoxication: seizures, delirium tremens, glucose, benzodiazepines per protocol, and not leaving a withdrawing patient to sleep it off.
Start lesson →Vaginal Bleeding in the Field
10 min
Pregnant and non-pregnant vaginal bleeding: shock, ectopic and miscarriage thinking, pads in place, and not packing the vagina.
Start lesson →Meningitis & Fever With Stiff Neck
10 min
Fever, stiff neck, photophobia, or petechiae: isolation thinking, sepsis support, and not waiting for a hospital lumbar puncture to treat the patient as sick.
Start lesson →Sickle Cell Crisis in the Field
10 min
Vaso-occlusive pain, acute chest syndrome, and stroke in sickle cell disease: oxygen, analgesia per protocol, and taking pain seriously.
Start lesson →Hypoglycemia Refusal & Capacity
10 min
After correcting hypoglycemia: capacity, a real meal, why the glucose fell, and when a refusal requires medical control.
Start lesson →Pediatric Septic Shock in the Field
12 min
Compensated pediatric shock: tachycardia, cap refill, and mentation before hypotension. Bolus, reassess the lungs, pediatric-capable emergency department.
Start lesson →Stroke Mimics
11 min
Hypoglycemia, post-ictal Todd’s paralysis, migraine, and functional presentations as stroke mimics — still run the stroke path when criteria are met.
Start lesson →Adrenal Crisis in the Field
11 min
Adrenal crisis from the steroid list and shock picture: glucose, fluids, and steroid if protocol allows — not unexplained hypotension.
Start lesson →Thunderclap Headache & SAH
11 min
Thunderclap or worst-headache-of-life presentations and subarachnoid hemorrhage thinking: ABCs, glucose, no improvised blood-pressure drop, and a hospital that can image.
Start lesson →Field Death Notification
12 min
After termination of resuscitation: one speaker, the word died, a pause, and a short script — not euphemism and not leaving the family without a statement.
Start lesson →Imminent Childbirth
12 min
Crowning on scene: stay, control the head, nuchal cord, dry, stimulate, and warm the newborn, delayed cord clamping if the infant is well, and two patients on the radio.
Start lesson →Weakness and Dizziness in Older Adults
12 min
Weakness and dizziness in older adults: ACS, stroke, hemorrhage, infection, and medications — a high-risk screen instead of a dismissive label.
Start lesson →Cognitive Bias in Field Decisions
10 min
Anchoring on dispatch, confirmation bias, and premature closure: treat the first story as a hypothesis and reassess after the first intervention.
Start lesson →Serotonin Syndrome vs NMS
12 min
Clonus and serotonergic drugs versus rigid muscles and an antipsychotic. Cool, support the airway, benzodiazepines per protocol, and bring the medication list.
Start lesson →Thyroid Storm and Myxedema
11 min
Thyroid storm: hot, fast, altered — cool and support, and do not use aspirin for the fever. Myxedema: cold, slow, altered — airway, glucose, gentle warming.
Start lesson →BRUE: The Resolved Infant Event
10 min
The infant looks fine now after a color, breathing, or tone change. That is not a field clearance. BRUE low-risk rules belong to the clinician after a full exam.
Start lesson →Refractory Anaphylaxis
12 min
Anaphylaxis that persists: repeat IM epinephrine per protocol, airway early, supine if hypotensive. Never IV-push the IM concentration. Glucagon does not replace epinephrine.
