Common Pitfalls
Translation Traps (for Russian speakers)
- Russian uses a direct calque 'гипотензия' (gipotenziya), which is a perfect equivalent. No major trap, but be aware of the technical register.
Common Mistakes
- Confusing 'hypotension' with 'dehydration' or 'anemia', which can cause it but are not the same. Mispronouncing the 'o' in the second syllable (it's a schwa /ə/).
