Public high school students would be required to learn CPR under a measure before the Maryland General Assembly.
Supporters have scheduled a news conference on Thursday. They will include a Virginia family whose child died as a result of cardiac arrest.
Sen. Catherine Pugh, D-Baltimore, is sponsoring the bill.
The measure would require a public school student to complete instruction in cardiopulmonary resuscitation and the use of an automated external defibrillator to graduate from high school.
The requirement would begin in the next school year.
