Flow Rates
- max flow rate in cc/min
- massive transfusion: 150 cc/min
- IO: typically 18
- French sizes are larger than gauge and starts from 4F after 16G
- Triple lumen: flow rate is decreased because increased length, total 100 cc/min:
IV Infusion
- IV infusion can be done via 2 ways
- gravity with roller clamp, dial-a-flow
- infusion pump: this is what our hospital does
Central Lines
- Non-tunneled catheter: usually what we think as central lines. E.g. triple lumen. The line comes out of skin where it is inserted.
- Tunneled catheter: passes under the skin with separate exit site, usually the chest. Tunneling helps prevent infection and improves stability
- Cuffed catheter: cuff that allows skin to grow around it
- Triple Lumen: usually non tunneled three lumen catheter. Usually has one 16G and two 18G. Usually 7 French.
- Vas cath: aka HD cath, large diameter catheters, up to 16 French, allow flow rate 200-300 cc/min, usually has 2 lumen, one for blood coming out and one for blood returning to patient
