The Blue Star of Life is recognized by the medical community as a medical emergency symbol. NNEMS has included this symbol to bring wholeness to both the Navajo culture and Emergency Medical Services.

There are seven colors used in the shield: blue, red turquoise, flesh, black and white. Each color has a meaning in the shield.

The Navajo Twin were born to protect the Navajo people. Therefore the Navajo Twins represent protection of the Navajo people. NNEMS acknowledges and includes this cultural aspect. NNEMS is the protector of the people as well, by providing quality health care.

The four sacred mountains are also symbolized. Mt. Blanca located in Alamosa, Colorado represents the east. The San Francisco Peak Located in Flagstaff, Arizona represent the west. Mt. Taylor near Grants, New Mexico represents the south, and the north is pre presented by Hesperus Mountain located near Durango, Colorado. The Navajo people are blessed to have their ancestral land with the Four Sacred Mountains surrounding them, giving them strength.

The Twins are in a "wrapping" symbolizing protection and or stabilization, such as an infant is wrapped in a cradle board. The three lines surrounding the shield represent the rainbow and the sovereign immunity.
