Share:
- 1Deep suctioning with rapid withdrawal; suction for 5 seconds in adults; pressure <80 mmHg; saline instillation is mandatory for all routines.
- 2Apply continuous suction without rotation; suction ≤20 seconds; pressure <100 mmHg in adults; large-bore catheter preferred.
- 3Apply suction while withdrawing the catheter with slow rotation; suction ≤15 seconds; pressure 80-120 mmHg; catheter diameter less than 50% of the endotracheal tube inner diameter.✓
- 4Apply suction during catheter insertion; suction for 30 seconds; pressure >200 mmHg; catheter equal to tube diameter.
Correct answer
Apply suction while withdrawing the catheter with slow rotation; suction ≤15 seconds; pressure 80-120 mmHg; catheter diameter less than 50% of the endotracheal tube inner diameter.
