Answer:
False.
Explanation:
Ultrasonic devices should not be used on patients with pacemakers, even shielded ones.
While a shielded pacemaker may be less susceptible to electromagnetic interference (EMI) from ultrasonic devices, there is still some risk of interference, which could potentially disrupt the proper functioning of the pacemaker and put the patient's health at risk.
Here's why:
Shielding isn't perfect: No pacemaker shielding is 100% effective in blocking EMI. Even a small amount of interference could be enough to disrupt the pacemaker's rhythm.
Different types of ultrasonic devices: The risk of interference varies depending on the type of ultrasonic device being used. Magnetostrictive ultrasonic devices, which are commonly used in dentistry, pose a higher risk than piezoelectric devices.
Individual variations: Patients with pacemakers also have varying levels of sensitivity to EMI. Some patients may experience no problems with ultrasonic devices, while others may experience significant interference.
Therefore, it is always best to avoid using ultrasonic devices on patients with pacemakers, regardless of whether the pacemaker is shielded. This is the safest approach to ensure patient safety and avoid any potential complications.
It's important to consult with a medical professional before using any type of medical equipment on a patient with a pacemaker to ensure their safety and avoid any potential risks.
