This pump is compact and lightweight so it takes up very little space and can be easily placed in any emergency bag. The vacuum can be adjusted from 100% (450 mmHg) for the use on adults to 50% (225 mmHg) for the use on children. The pump or handle is reusable but the canister kit is for single use only. The Ambu Res-Cue Pump contains an overfill protection which prevents contamination inside the pump/handle and eliminates the need for flush-through procedures. This feature also prevents exhaust splashing of liquids. The collection container can be easily replaced and reduces the time for making the pump ready again.
