What are some strategies to help clear the lungs before doing chest x ray?

There are no specific strategies needed to help clear the lungs before a chest x-ray. Chest x-rays are a simple and painless imaging test that uses a small amount of radiation to produce images of the chest. In most cases, no preparation or special breathing techniques are required. You may be asked to remove any jewelry or clothing that could interfere with the x-ray, but otherwise you can relax and remain still while the x-ray is taken.
