Respirators are medical devices that help patients breath on their own, or even completely undertake the breathing procedure entirely if the patient is unable to do so. Respirators are separated into two categories:
- invasive ventilation respirators that are installed after the intubation of the trachea through the endotracheal tube.
- non-invasive ventilation respirators that are applied via a mask. This type of respirators can be activated and interrupted more easily by the patient, while they enable the user to talk, eat, and cough during operation. Moreover, they can be used periodically for a couple of hours a day, and do not require a patient suppression or the hydration of the air.
