Learn about the VO2 max exercise test. </p><p>Your child's doctor has asked that your child complete a VO2 max exercise test. This information explains what the test is, how to prepare for it and how it is done. Parents can use this information to help their child prepare for the test.</p><h2>What is an exercise test?</h2><p>The exercise test tells your child's doctor if your child's heart beats in a regular way when they do things like walk, run and ride a bicycle. These tests give information your child's doctor cannot measure while your child sits or rests. The doctor can also see how your child's heart works compared with how other children's hearts work.</p><h2>What is the VO2 max exercise test?</h2><p>The VO2 max exercise test measures how well your child's heart and lungs send oxygen to the muscles during heavy exercise. Your child will be asked to either pedal a special bicycle or walk on a treadmill, which is like a moving sidewalk. Your child's heartbeat, blood pressure and oxygen level will be measured while they exercise.</p> <figure class="asset-c-80"><img src="https://assets.aboutkidshealth.ca/akhassets/Exercise_test_VO2_max_MED_ILL_EN.jpg" alt="Child pedaling while wearing a saturation monitor, mouthpiece, blood pressure cuff and electrocardiograph sensor" /><figcaption class="asset-image-caption">1: Blood pressure cuff, 2: Electrocardiograph (ECG) Sensor, 3: Blood pressure monitor, 4: Bicycle, 5: ECG monitor, 6: Mouthpiece, 7: Saturation monitor</figcaption> </figure><h2>Key points</h2> <ul> <li>The VO2 max exercise test measures how well your child's heart and lungs send oxygen to the muscles during heavy exercise. </li> <li>The test uses machines to measure your child's oxygen levels, blood pressure and heartbeat while your child rides a special bike or walks on a treadmill. </li> <li>Your child should let the technologist know right away if they have chest pain, trouble breathing, dizziness, irregular heartbeat or tired legs during the test. </li> </ul><h2>Who will give the test?</h2> <p>Two technologists will give your child the VO2 max exercise test. Technologists are people who are trained to give the test on the machines in the hospital. </p> <h2>First your child will be asked to do a breathing test</h2> <p>Before the VO2 max exercise test, your child will be asked to do a breathing test called a pulmonary function test. The pulmonary function test is done in two parts: </p> <ul> <li>The first part of the test is like blowing out the candles on a birthday cake. It measures how much and how fast your child can blow air out. </li> <li>The second part of the test measures how much air your child can breathe in and out in 15 seconds. </li> </ul> <p>Before the test, your child will be given a clip to put on their nose. The nose clip makes sure that your child's breath comes out only through the mouth. It also makes it easier to measure the amount of air going in and out of the mouth. </p> <p>Your child will be given a mouthpiece to blow in. Your child will breathe through the mouthpiece into a machine called a spirometer. The spirometer measures your child's breathing. </p> <p>These tests use a clean, sterilized mouthpiece and nose clip.</p> <h2>Machines will measure your child's oxygen levels, blood pressure and heartbeat</h2> <p>To prepare your child for the VO2 max exercise test, the technologist will do the following things:</p> <ul> <li>The technologist will put a device called a saturation monitor on your child's forehead. It measures the amount of oxygen in your child's blood. The device is kept in place with a headband. </li> <li>The technologist will put a sleeve called a blood pressure cuff on your child's arm. The blood pressure cuff will be used to check how hard your child's heart is pumping during the test. </li> <li>Your child will be hooked up to a computer called an electrocardiograph (ECG). The ECG makes pictures of how your child's heart beats during physical activity. </li> </ul> <h2>Connecting your child to the ECG</h2> <p>Here are the steps the technologist will follow to hook up your child to the ECG:</p> <ol> <li>The technologist will wipe the skin on your child's chest with water. This is to make sure the skin is very clean.</li> <li>The technologist will gently rub the cleaned skin with a scratchy pad. This will make it easier for the stickers to stay on and provide a good picture of your child's heartbeat.</li> <li>The technologist will put 10 stickers, called electrodes, on your child's chest.</li> <li>The technologist will attach one end of a wire to each electrode and the other end of each wire to the ECG machine.</li> </ol> <h2>Your child will ride a special bicycle or walk on a treadmill</h2> <p>Most VO2 max exercise tests are done on a special bicycle, but sometimes the test is done using the treadmill. If your child is using the bicycle, the technologist will adjust the seat to fit your child's height. The bicycle does not move and your child does not have to balance on it. </p> <p>Before starting the test, your child will be given a nose clip and a rubber mouthpiece to breathe into. The mouthpiece is connected to a machine called a metabolic cart. It tests how well your child's body takes in oxygen and sends it to the muscles.</p> <p>The technologist will then tell your child how fast to pedal. It will feel like riding a bike up a hill that gets steeper and steeper. Your child will be asked to pedal for between five and 10 minutes. </p> <p>When your child cannot pedal any more, the technologist will make the bike easier to pedal. After one minute the technologist will remove the mouthpiece and nose clip. Your child will then be asked to pedal slowly for two minutes to cool down. </p> <p>Your child's heart rate and blood pressure will be monitored at rest, during exercise, and during the cool down period.</p> <p>It is important that your child follows the directions the technologist gives for the test. Encourage your child to try their best. This way, the doctors can get the most accurate results. They will have a clearer picture of your child's heart and how it works. </p> <h2>Your child should let the technologist know if they have problems during the test</h2> <p>Your child should let the technologist know right away if they have any problems during the test. The technologist will show your child how to use hand signals. Your child can use the hand signals to let the technologist know if they have any of the following problems:</p> <ul> <li>pain in the chest </li> <li>trouble breathing </li> <li>dizziness </li> <li>heartbeat feels irregular </li> <li>tired legs </li> </ul> <p>If the technologists see a problem during any of the tests, they will tell the cardiologist right away.</p> <h2>You may be able to stay with your child during the test</h2> <p>You can discuss with the technologist if it is best for your child if you stay. You must not talk to your child during the test so that they can concentrate.</p><h2>Your child should sleep well and eat a good breakfast before the test</h2> <p>To get ready for the exercise test, your child should do the following:</p> <ul> <li>Your child should be well rested the night before the test. </li> <li>Your child should eat a good breakfast on the day of the test. A good breakfast includes servings of grains, protein and fruit. One example of a good breakfast is egg, peanut butter or cheese; toast; juice or fruit; and milk. </li> <li>Your child should finish eating one to two hours before they start the test. </li> <li>Your child should wear or bring a T-shirt, shorts, non-slip, closed toe, running shoes and socks for the test. </li> </ul><h2>At SickKids</h2> <p>The test is done on the 4th floor of the hospital on ward 4B.

Vous en apprendrez davantage sur le test d’exercice de Vo2 max. </p><p>Le médecin de votre enfant a demandé que votre enfant fasse un test d’exercice qui mesure le Vo2 max. Les renseignements ci-dessous expliquent ce qu’est le test, comment s’y préparer et comment il se déroule. Les parents peuvent utiliser ces renseignements pour aider leur enfant à se préparer. </p><h2>Qu’est-ce qu’un test d’exercice?</h2><p>Le test d’exercice montre comment fonctionne le cœur de votre enfant pendant qu’il fait des choses comme marcher, courir et faire de la bicyclette. Ce test fournit des renseignements que le médecin ne peut pas mesurer quand votre enfant est assis ou au repos. Le médecin peut aussi voir comment fonctionne le cœur de votre enfant en comparaison à celui d’autres enfants. </p><h2>Qu’est-ce que le test d’exercice du Vo2 max?</h2><p>Le test d’exercice du Vo2 max mesure la capacité du cœur et des poumons d’envoyer de l’oxygène aux muscles pendant l’exercice intense. On demandera à votre enfant de pédaler sur une bicyclette ou de marcher sur un tapis roulant, qui ressemble à un trottoir en mouvement. Le rythme cardiaque, la tension artérielle et le niveau d’oxygène de votre enfant seront mesurés quand il fera de l’exercice. </p> <figure class="asset-c-80"> <img src="https://assets.aboutkidshealth.ca/akhassets/Exercise_test_VO2_max_MED_ILL_EN.jpg" alt="Enfant pédalant en portant un moniteur de saturation, une embouchure, un capteur d’électrocardiographe et un brassard" /> <figcaption class="asset-image-caption">1 : Brassards pneumatiques pour évaluer la pression artérielle, 2 : Capteur d'électrocardiographe, 3 : Moniteur de pression artérielle, 4 : Bicyclette, 5 : Moniteur d'électrocardiographe, 6 : Embouchure, 7 : Moniteur de saturation</figcaption> </figure><h2>À retenir</h2><ul><li>Le test d’exercice de Vo2 max mesure la capacité du cœur et des poumons de votre enfant d’envoyer de l’oxygène aux muscles pendant l’exercice intense. </li><li>Pendant le test, des appareils mesurent les niveaux d’oxygène, la tension artérielle et le rythme cardiaque de votre enfant pendant qu’il pédale sur une bicyclette spéciale ou qu’il marche sur un tapis roulant. </li><li>Votre enfant doit mentionner immédiatement au technologue s’il a des douleurs à la poitrine, de la difficulté à respirer, des étourdissements, un rythme cardiaque irrégulier ou de la fatigue dans les jambes pendant le test. </li></ul><h2>Qui fera passer le test?</h2> <p>Deux technologues feront passer le test à votre enfant. Les technologues sont des personnes formées pour faire passer le test sur des machines de l’hôpital. </p> <h2>Votre enfant devra d’abord faire un test de respiration</h2> <p>Avant le test de Vo2 max, votre enfant pourrait devoir faire un test de respiration appelé test de fonction pulmonaire, qui comprend deux parties.</p> <ul> <li>La première partie ressemble à souffler des chandelles sur un gâteau. Elle mesure la quantité d’air que votre enfant peut expirer et à quelle vitesse. </li> <li>La deuxième partie du test mesure la quantité d’air que votre enfant peut inspirer et expirer en 15 secondes. </li></ul> <p>Avant le test, votre enfant recevra une pince qu’il devra mettre sur son nez. Cette pince fait en sorte que la respiration de votre enfant sort seulement de la bouche. Elle facilite aussi la mesure de la quantité d’air qui entre dans la bouche et qui en sort. </p> <p>Votre enfant recevra un embout buccal dans lequel il devra expirer. La respiration captée par l’embout se rendra à un appareil appelé spiromètre. Ce spiromètre mesure la respiration de votre enfant. </p> <p>L’embout et la pince sont propres et stériles. </p> <h2>Des machines mesureront les niveaux d’oxygène, la tension artérielle et le rythme cardiaque de votre enfant </h2> <p>Pour préparer votre enfant pour le test d’exercice du VO2 max, le technologue fera ce qui suit.</p> <ul> <li>Le technologue installera un appareil appelé saturomètre sur le front de votre enfant. Il mesure la quantité d’oxygène dans le sang. Cet appareil est maintenu en place au moyen d’un bandeau. </li> <li>Il placera un manchon appelé brassard sur le bras de votre enfant. Ce brassard mesure l’intensité des battements du cœur de votre enfant pendant le test. </li> <li>Votre enfant sera branché à un ordinateur appelé électrocardiographe, qui prend des images des battements du cœur de votre enfant pendant l’activité physique. </li></ul> <h3>Brancher l’enfant à l’électrocardiographe</h3> <p>Voici ce que fera le technologue pour brancher votre enfant à l’électrocardiographe.</p> <ol> <li>Il frictionnera la poitrine de votre enfant avec de l’alcool à friction, pour bien nettoyer la peau. </li> <li>Le technologue frottera doucement la peau propre avec un tampon rugueux, ce qui facilitera l’adhérence des timbres collants et donnera une meilleure représentation des battements du cœur. </li> <li>Le technologue placera 10 timbres collants, appelés électrodes, sur la poitrine de votre enfant.</li> <li>Le technologue attachera l’extrémité d’un câble à chaque électrode et l’autre à l’électrocardiographe. </li></ol> <h2>Votre enfant pédalera sur une bicyclette spéciale ou marchera sur un tapis roulant</h2> <p>La plupart des tests d’exercice de VO2 max se font sur une bicyclette spéciale, mais parfois, le test se fait sur un tapis roulant. Si votre enfant utilise la bicyclette, le technologue ajustera la hauteur du siège. La bicyclette ne bouge pas et votre enfant n’aura pas à faire preuve d’équilibre. </p> <p>Avant de commencer le test, votre enfant recevra une pince pour le nez et un embout buccal en caoutchouc où il pourra respirer. L’embout est branché à un appareil appelé instrument de mesure du métabolisme. Il teste la capacité du corps de votre enfant à absorber l’oxygène et à l’envoyer dans les muscles. </p> <p>Le technologue dira à votre enfant la vitesse où il doit pédaler. Le test ressemble à monter un chemin montagneux dont la pente devient de plus en plus grande. On demandera à votre enfant de pédaler entre cinq et dix minutes. </p> <p>Quand votre enfant ne pourra plus pédaler, le technologue rendra les mouvements plus faciles. Après une minute, le technologue retirera l’embout et la pince. Votre enfant pédalera ensuite pendant deux minutes pour récupérer. </p><p>Le rythme cardiaque et la tension artérielle seront examinés au repos, pendant l’exercice et pendant la période de récupération. </p> <p>Il importe que votre enfant suive les directives du technologue pendant le test. Encouragez votre enfant à faire de son mieux. De cette manière, les médecins pourront obtenir les résultats les plus justes et auront une meilleure représentation du cœur de votre enfant et de son fonctionnement. </p> <h2>Votre enfant doit le signaler au technologue s’il a des problèmes pendant le test </h2> <p>Votre enfant doit mentionner immédiatement au technologue s’il a l’un ou l’autre des problèmes suivants. Le technologue montrera à votre enfant comment utiliser des signaux de la main. Votre enfant pourra les utiliser pour signaler l’un ou l’autre de ces problèmes. </p> <ul> <li>douleur à la poitrine;</li> <li>difficulté à respirer;</li> <li>étourdissements; </li> <li>battements cardiaques irréguliers;</li> <li>fatigue dans les jambes.</li></ul> <p>Si le technologue voit un problème pendant le test, il le signalera immédiatement au cardiologue. </p> <h2>Vous pouvez rester avec votre enfant pendant le test</h2> <p>Vous pouvez observer votre enfant pendant qu’il fait la marche de six minutes. Cependant, le technologue vous demandera de ne pas parler à votre enfant. </p><h2>Votre enfant doit bien dormir et manger un bon déjeuner avant le test </h2> <p>Voici ce que votre enfant devrait faire pour se préparer.</p> <ul> <li>Votre enfant doit avoir une bonne nuit de sommeil. </li> <li>Votre enfant devrait manger un bon déjeuner le matin du test, qui comprend des portions de céréales, de protéine et de fruits. Par exemple, votre enfant peut manger des œufs, du beurre d’arachide ou du fromage, des rôties, du jus ou des fruits, et du lait. </li> <li>Votre enfant doit avoir cessé de manger d’une à deux heures avant le test. </li> <li>Votre enfant doit apporter un chandail à manches courtes, des pantalons courts et des souliers de course. </li></ul><h2>À l'hôpital SickKids</h2><p>Le test se fait au quatrième étage, dans l’aile 4B. Pour cette partie du test, veuillez vous enregistrer au poste des soins cardiaques, à l’aile 4B.</p>
