<unk>  is any mode of mechanical ventilation where every breath is<unk>  (i.e., patient triggered and patient cycled).<unk>  breathing is defined as the movement of gas in and out of the lungs that is produced in response to an individual's respiratory muscles. In a nutshell,<unk>  breathing is natural breathing. while at rest, a typical adult will take an average of 18 breaths per minute. Most people are unaware of their breathing patterns unless something interferes with the efficiency of this process. In extreme cases, mechanical ventilation is used when<unk>  breathing is inadequate or ceases entirely.
