trick to remember pallor
Pallor = PALe coLOR - lack of normal skin/mucosal color due to reduced blood flow or hemoglobin.
Quick memory trick:
"PALLOR" = People Always Look Little Or Red-less
But the more useful mnemonics are for causes of pallor:
Causes of Pallor - Mnemonic: "PALLOR"
| Letter | Cause |
|---|---|
| P | Poor perfusion (shock, heart failure) |
| A | Anemia (any cause) |
| L | Leukemia / blood cancers |
| L | Low temperature (vasoconstriction, cold) |
| O | Obstruction (arterial - PVD, Raynaud's) |
| R | Renal failure (chronic - EPO deficiency) |
Where to Look for Pallor (Exam Sites)
"Can't Miss Checking Every Nail"
- C - Conjunctiva (lower eyelid - most reliable)
- M - Mucous membranes (inside mouth/lips)
- C - Creases of palm
- E - Earlobes
- N - Nail beds
Quick Distinguishing Tips
- Conjunctival pallor = best indicator of anemia (not affected by skin tone)
- Central pallor (tongue, mucosa) = true pallor vs. peripheral (could be cold/shock)
- Lemon-yellow pallor = B12/folate deficiency anemia
- Waxy/greenish pallor = iron deficiency (historically "chlorosis")
The single best trick: pull down the lower eyelid - if the inner rim looks white/pale instead of pink-red, that's significant pallor regardless of the patient's natural skin color.
