You should have at least two suction machines before your child goes home from the hospital in case one machine breaks down. At least one of your suction machines should be portable so that you can “suction on the go” when outside your home.</p><p>Many brands of suction machines are available. Your local medical vendor will help you decide which one is best for your child. The vendor will also teach you how to use the suction machine you decide to buy.</p> <figure class="”asset-c-100”"><span class="asset-image-title">Parts of a suction machine</span><img src="" alt="A suction machine with labels for the canister, tubing, filter, pressure gauge and regulator, battery level, power light, AC plug and on and off switch" /> </figure> <p>All suction machines have: </p><ul><li>a filter</li><li>canister</li><li>vacuum gauge</li><li>a way to regulate the pressures</li><li>AC plug and/or a battery and charger</li><li>a power switch.</li></ul><div class="caution"><h3>P​recautions</h3><p>Between suctions, remember to plug the portable suction machine into an AC wall outlet so that it will be ready to use when you need it next. </p><ul><li>When using the machine in AC power mode, the on/off light will appear.</li><li>When using the machine in battery mode, the on/off switch will not light up.​​</li></ul></div><p>The battery on a fully-charged suction machine should last about 45 minutes, but this will vary from machine to machine. Generally, it will take about five minutes to re-charge the battery. Aim to use the battery for only 30 minutes at a time so that it can re-charge more quickly.</p><h2>How do I know the right size catheter for my child or how far I can suction?</h2><p>In general, the recommended suction catheter sizes and suction depth depend on the size and length of your child’s tracheostomy tube.​</p><table class="akh-table" border="1" style="width:100%;"><thead><tr><th colspan="2" scope="colgroup" style="text-align:left;">​Correct suction catheter size</th></tr><tr><th scope="col">Tracheostomy tube size (mm)</th><th scope="col">Recommended suction catheter size (Fr)</th></tr></thead><tbody style="text-align:center;"><tr><td>3.0</td><td> 6</td></tr><tr><td> 3.5</td><td> 8</td></tr><tr><td>4.0</td><td> 8</td></tr><tr><td> 4.5</td><td>10</td></tr><tr><td> 5.0</td><td> 10</td></tr><tr><td> 6.0</td><td> 10-12</td></tr><tr><td> 7.0</td><td> 12</td></tr></tbody></table><h3>Identifying the correct suction depth</h3><ul><li>Use a spare tracheostomy tube the same length as your child’s tube and a measuring tape.</li><li>Measure the distance from the tracheostomy tube connector to the end of the tracheostomy tube.</li><li>Record the suction depth on the tape measure.</li><li>Attach the tape measure to the cot/bedside/suction machine for future use.</li></ul><p>Use pre-measured suction catheters (where available) to ensure accurate suction depth.</p><p>Your child’s healthcare provider will review with you what type of tube and suction catheter your child needs, how far to insert the suction catheter and which setting to use for the suction machine.</p><p></p><table class="akh-table" border="1" style="width:100%;"><tbody><tr><td>Tracheostomy tube size:</td><td></td></tr><tr><td>Suction catheter size:</td><td></td></tr><tr><td>Depth of suction catheter insertion for tube suction:</td><td></td></tr><tr><td>Suction machine setting:</td><td></td></tr></tbody></table> ​​ <p></p> <a class="btn btn-primary" href="">Return to trach-vent learning hub</a><br>Suction machines, catheters and depthTrue
