English to Spanish Medical Medical: Health Care Dying process

Hola! Quisiera saber cómo traducir "release" en el siguiente contexto. Habla de los últimos momentos de vida de los pacientes terminales. Aquí va el párrafo:

WITHDRAWAL - The person may seem unresponsive, withdrawn, or in a comatose-like state.This indicates preparation for release, a detaching from surroundings and relationships, and a beginning of letting go. Since hearing remains all the way to the end, speak to your loved one in your normal tone of voice, identify yourself by name when you speak, hold his or her hand, and say whatever you need to say that will help the person let go.

¿Puede traducirse como "liberación"?

Muchas gracias!
