📒 The 1-minute cheat sheet
📌 Low Sugar
Sudden onset
Cool, clammy, fast pulse
Odd behavior
📌 High Sugar
Days to develop
Warm, dry, thirsty
DKA: fruity breath, Kussmaul
✅ Treat
Oral glucose: awake + can swallow
Can't swallow → nothing by mouth
Recheck after
📚 Diabetic Emergencies — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what changes the plan, and what to hand over.
Diabetic emergencies are examined as a contrast: low sugar comes on fast and is fixed fast, high sugar builds over days and needs the hospital. The key EMT decision is whether the patient can safely swallow oral glucose.
🔑
Key points
Understand these first
Hypoglycemia: sudden onset, cool clammy skin, fast pulse, confusion or odd behavior.
DKA: fruity breath and deep rapid breathing (Kussmaul) with abdominal pain.
Oral glucose only if awake, able to swallow and able to protect the airway.
Recheck mental status and glucose after treatment; skipped meals and new insulin doses are clues.
✅
Treatment priorities
What to do, in order
Altered patient: check glucose early — it is quick and changes treatment.
Unable to swallow: nothing by mouth; manage the airway and request advanced care.
Hyperglycemia with shock signs: treat the shock and transport.
🚩
Red flags — report now
Escalate immediately
Unresponsive diabetic patient
Kussmaul breathing with altered mental status
Low sugar in a patient on long-acting medication — it can return
🗣️
Patient teaching
What patients must know
When unsure whether sugar is high or low, glucose for the awake patient does little harm.
An 'intoxicated' patient may be hypoglycemic — check before assuming.
