The mouth-to-mouth technique is performed as follows (see the video below):

  • The nostrils of the patient are pinched closed to assist with an airtight seal

  • The provider puts his mouth completely over the patient’s mouth

  • The provider gives a breath for approximately 1 second with enough force to make the patient’s chest rise
