Effective use of a BVM requires proper technique and practice. Here are the steps: 1. Position the patient supine and ensure the airway is clear. 2. Position yourself at the patient's head. 3. Use the C-E clamp technique to hold the mask securely over the patient's nose and mouth. 4. Squeeze the bag to deliver a breath every 5-6 seconds for adults, and every 3-5 seconds for infants and children. 5. Observe chest rise to confirm effective ventilation.
