2. Kneel beside the person with your knees near the person's body and spread about shoulder width apart.
3. Place the heel of one hand in the center of the person's chest, with your other hand on top. Interlace your fingers and make sure the fingers are up off the chest.
4. Position your body so that your shoulders are directly over your hands and lock your elbows to keep your arms straight.
5. Keeping your arms straight, use your body's weight to compress the center of the chest to a depth of at least 2 inches and a rate of between 100 and 120 compressions per minute, or one about every half second. After each compression, let the chest return
to its normal position.
How do you give breaths with a face shield? - answer1. First, place the face shield over the person's face, ensuring the one-way valve is over their mouth.

3. Pinch the nose shut, take a normal breath and make a complete seal over the person's mouth.
4. Blow into their mouth for about 1 second, while looking to see that the chest begins to
rise.
5. Allow the person's chest to fall and the air to exit while you take another breath, make
a seal and give a second breath.

4. Maintain a good seal.
5. Take a normal breath and make a complete seal over the mask valve with your mouth.
6. Blow into the one-way valve for about 1 second, while looking to see that the chest begins to rise.
