Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'интенсивная терапия отделение'. The correct Russian equivalent is 'отделение реанимации и интенсивной терапии' (OРИТ) or commonly just 'реанимация'. 'Интенсивная терапия' refers to the treatment, not the place.
Common Mistakes
- Using uncountably (e.g., 'He is in intensive care unit' – missing article).
- Confusing 'intensive care' (the treatment) with 'intensive care unit' (the place).
- Misspelling as 'intensive *car* unit'.
