The manufacturer's instructions for use list closed suction catheter variants in sizes from 5Fr to 16Fr. Pediatric variants (PA and PP types) are listed in 5Fr to 8Fr. The DW type is listed in 10Fr and 12Fr only. The remaining variants cover the wider range up to 16Fr. The full table is on the closed suction catheter detail page.
How buyers use the size range
Size selection depends on the patient's airway, the tube in place, and the clinical unit's protocol. This guide does not publish a size conversion table and does not recommend a size for any patient group, because no such table is documented in the source. The practical buying steps are: confirm the variant that matches the tube type (endotracheal or tracheostomy), confirm the size range stocked for that variant, and confirm the switch and connector configuration.
What to confirm before ordering
- Confirm the variant and size for your patient group and tube type.
- Confirm the switch type and connector configuration.
- Confirm the packaging quantities for each size.
Follow the clinical unit's own protocol for size selection, and confirm the stocked sizes with the supplier before placing an order.
