This creates an oxygen saturation of over 95 per cent. However, if your child has a heart or lung condition that prevents red blood cells from picking up oxygen, their oxygen saturation will be lower. </p><p>Your child's healthcare team will let you know the target oxygen saturation range for your child.</p><h2>What is oximetry?</h2><p> <em>Oximetry</em> is the measurement of oxygen saturation in your child’s blood. You will use oximetry to check that your child's oxygen saturation levels are in line with the target set by your child's healthcare team. </p><h2>What is an oximeter?</h2> <figure> <img src="https://assets.aboutkidshealth.ca/akhassets/trach_oximeter_portable_EN.jpg" alt="A portable oximeter" /> </figure> <p>An <em>oximeter</em> is a machine that monitors your child’s oxygen saturation (SpO<sub>2</sub>) as well as their heart rate. </p><p>An oximeter can be used at home and when travelling, as most oximeters are portable. The machine has an internal battery and alarms for drops in SpO<sub>2</sub> levels and heart rate.</p><h2>Why does my child need an oximeter?</h2><p>Your child's healthcare team might recommend an oximeter to:</p><ul><li>alert you and other caregivers to sudden drops in your child’s SpO<sub>2</sub> and/or heart rate</li><li>alert you and other caregivers to potential oxygen or equipment failures</li><li>monitor your child so that you and your child’s healthcare team can make better informed healthcare decisions (for example whether your child can stop oxygen therapy or reduce the amount of oxygen they use).</li></ul><div><h2>How does an oximeter work?</h2><p>While in use, the oximeter continuously calculates and gives a reading of your child's oxygen saturation and heart rate. </p><p>The measurement is taken by placing a probe (a clip or a wrap) on your child at a point where a pulse can be detected easily. This is usually the fingertip for older children and the hand or foot for babies and younger children.​ </p><p></p><p>The probe has a small red light on one side and a detector on the other side. The red light shines through your childs finger or toe and is seen by the detector on the other side. The detector then measures the blood's oxygen saturation. ​</p> <figure class="asset-c-100"> <img src="https://assets.aboutkidshealth.ca/akhassets/trach_ox_sat_monitor_EN.jpg" alt="Numbered parts of an oxygen saturation moniter" /> </figure> <table class="akh-table"><thead><tr><th colspan="3" scope="colgroup" style="text-align:left;">​Parts of an oximeter</th></tr><tr><th>Number</th><th>Control indicator</th><th>Description</th></tr></thead><tbody><tr><td>1</td><td>AC power indicator</td><td>Lights up when oximeter is plugged into AC power</td></tr><tr><td>2</td><td>Power button</td><td>Turns the oximeter on and off</td></tr><tr><td>3</td><td>Up/down button</td><td>Changes the volume of the alarm tone</td></tr><tr><td>4</td><td>Alarm limits button</td><td> Changes the alarm limits</td></tr><tr><td>5</td><td>Signal IQ/pulse bar</td><td>Indicates the quality of the pulse signal</td></tr><tr><td>6</td><td>Oxygen saturation display</td><td>Displays the oxygen saturation (SpO<sub>2</sub>) measurement</td></tr><tr><td>7</td><td>Alarm silence button</td><td>Silences all alarms (for example SpO<sub>2</sub>, heart rate and low battery alarm)</td></tr><tr><td>8</td><td>Alarm light</td><td>Flashes to indicate an alarm condition</td></tr><tr><td>9</td><td>Perfusion bar</td><td>Indicates the quality of <em>perfusion</em> (blood flow around the body); the higher the bar, the better the perfusion</td></tr><tr><td>10</td><td>Heart rate display</td><td>Displays the heart rate measurement</td></tr><tr><td>11</td><td>Enter button</td><td>Accesses the setup menu</td></tr><tr><td>12</td><td>Brightness button</td><td>Changes the level of brightness</td></tr><tr><td>13</td><td>Battery charge bar</td><td>Indicates the level of battery charge</td></tr><tr><td>14</td><td>Speaker</td><td>Allows you to hear any alarms</td></tr><tr><td>15</td><td>Patient cable connector</td><td>Connects to the oximeter sensor</td></tr></tbody></table><p></p><h2>How long does the oximeter battery last?</h2><p>The oximeter should be plugged in whenever possible to charge the internal battery. When the internal battery is fully charged, the oximeter can work for up to seven hours. All models are different, however, so please refer to the user manual for your particular machine.</p><p>During normal patient monitoring, the battery charge bar will light up green from left to right to indicate the available battery charge when the oximeter is unplugged.</p><h2>Where do I get an oximeter and the related equipment?</h2><p>You can borrow the oximeter and all the related supplies (probes, cables and wrap) through the <a href="http://ontvep.ca/w/" target="_blank">Ventilator Equipment Pool (VEP)</a>. This is funded by the Ontario Ministry of Health’s <a href="https://www.ontario.ca/page/assistive-devices-program" target="_blank">Assistive Devices Program (ADP)</a>, to which you need to apply.</p><p>Your healthcare team will guide you through the application process and help you understand the oximeter.</p><h2>How do I know when and how to return the oximeter?</h2><p>Your child’s doctor will tell you when you can return the oximeter. Once you get confirmation, call the VEP (the number is on the oximeter) for information on how to return it.</p><p></p> <a class="btn btn-primary" href="https://www.aboutkidshealth.ca/trachvent">Return to trach-vent learning hub</a><br></div>Oxygen saturation monitoring: General knowledgeTruehttps://www.aboutkidshealth.ca/Article?contentid=2963&language=Englishhttps://www.aboutkidshealth.ca/Article?contentid=2961&language=English
