• If the MiniONE® feels too loose or too tight, one option is to adjust the volume of water in the balloon (always consult a healthcare professional before adjusting the volume of water in the balloon). Table 1 shows the minimum, recommended, and maximum volume of water for each French size of the MiniONE®.
• Be sure to check the current balloon volume before making any adjustments. To do this, insert an empty slip tip syringe into the MiniONE® balloon fill valve and pull back on the plunger (Fig. 1). Be sure to keep one hand on the device so it stays in place. Use the volume indicators on the syringe to determine how much water you just removed from the balloon and replace it with new water. If you do not have access to fresh water, you can re-fill the balloon with the water that is currently in the syringe. Compare the amount of water you removed from the MiniONE® to Table 1. If the MiniONE® fit is too loose, increase the amount of water in the balloon, but stay within the recommended amounts listed in Table 1. One option is to add an additional 0.5 ml of water to the balloon and see if that improves the fit. For example, you can fill the balloon with 3.0 ml of water instead of 2.5 ml of water. If the MiniONE® fits too tight, decrease the amount of water in the balloon, but stay within the recommended amounts listed in Table 1. One option is to reduce the water volume by 0.5 ml and see if that helps. For example, you could fill the balloon with 2.0 ml of water instead of 2.5 ml.
• If the MiniONE® does not properly fit, even though you increased or decreased the volume of water in the balloon, the stoma may need to be re-measured for a longer or shorter MiniONE® G-Tube.
• The MiniONE® should be able to turn easily without rubbing the patient’s skin. If the MiniONE® does not turn easily or if there is redness/bleeding at or around the stoma, call your healthcare provider. The stoma may need to be re-measured for a longer MiniONE®
• Each time the tube is changed, the stoma length should first be measured with the AMT Balloon Stoma Measuring Device (BSMD).
• NOTE: The MiniONE® should be able to move a little from side-to-side without too much force from the patient’s skin. If the MiniONE® does not move or, if you see redness/bleeding at the stoma or the area directly underneath the MiniONE®, call your provider. The stoma may need to be re-measured for a longer MiniONE®.
