An breathing or anesthesia apparatus and a process for operating a breathing or anesthesia apparatus are provided in which only a very low energy consumption occurs outside of the operating times. The breathing or anesthesia apparatus ( 1 ) is put into an energy-saving mode and a function pretest is performed before putting the apparatus into the energy-saving mode. A function self-test is carried out when the breathing or anesthesia apparatus is put into a standby mode.
1. A process for operating a breathing or anesthesia apparatus, the process comprising the steps of:
providing a breathing or anesthesia apparatus;
operating the breathing or anesthesia apparatus in a respiration mode wherein the breathing or anesthesia apparatus provides breathing gas to a patient for respiration;
operating the breathing or anesthesia apparatus in a standby mode wherein the breathing gas is not provided to the patient;
operating the breathing or anesthesia apparatus in energy saving mode wherein the apparatus is less operational than the standby mode, the energy saving mode using less power than the respiration mode and the standby mode;
operating the breathing or anesthesia apparatus in a pretest mode wherein a first plurality of functions of the breathing or anesthesia apparatus is tested;
operating the breathing or anesthesia apparatus in a self test mode wherein a second plurality of functions of the breathing or anesthesia apparatus is tested, the second plurality of functions being different than the first plurality of functions;
automatically changing operation of the breathing or anesthesia apparatus from the respiratory mode to the pretest mode before operation of the breathing or anesthesia apparatus changes from the respiratory mode to the energy-saving mode, before operation of the breathing or anesthesia apparatus changes from the respiratory mode to the self test mode, and before operation of the breathing or anesthesia apparatus changes from the respiratory mode to the standby mode.
2. A process in accordance with claim 1 , further comprising:
automatically changing operation of the breathing or anesthesia apparatus from the energy saving mode to the self test mode before the breathing or anesthesia apparatus changes from the energy-saving mode to the standby mode and/or the respiration mode.
3. A process in accordance with claim 2 , wherein:
the self test mode is performed for a longer time period than the pretest mode;
the self test mode tests more components than the pretest mode;
the pretest mode test more essential functions of the breathing or anesthesia apparatus than the self test mode.
