Episode Description
🧠 Clinical Context:
Blood pressure errors due to bad positioning = misdiagnosis and mistreatment.
We often blame the drug, when the data was flawed to begin with.
🧪 Study Highlights:
104 patients tested with 3 positions:
Hand in lap: BP falsely elevated by 4 mmHg.
Arm unsupported: +6 mmHg (most common real-world scenario).
Arm supported at heart level: accurate.
✅ Gold Standard Technique:
Seated, feet flat on floor, arm supported at heart level, relaxed.
No caffeine, nicotine, or exercise 30 minutes prior.
No talking. Cuff on bare skin, correct size (80% of upper arm).
Wait 5 minutes pre-reading. Repeat if >5 mmHg difference.
⚠️ Clinical Consequences:
Misclassified HTN → overtreatment, hypotension, dizziness.
Standardize BP checks in your clinic—“militant consistency” matters.
