Answer

Answer

The BVM or invasive airway technique is performed as follows:

  • The provider ensures a tight seal between the mask and the patient’s face.

  • The bag is squeezed with one hand for approximately 1 second, forcing at least 500 mL of air into the patient’s lungs.

Next, the provider checks for a carotid or femoral pulse. If the patient has no pulse, chest compressions are begun.
