impedance threshold

Impedance threshold refers to a specific level of electrical resistance that must be reached or surpassed for a device, such as a medical ventilator or electrical system, to operate or trigger certain functions. It acts as a sensitivity setting, helping the system distinguish between normal signals and noise or unintended inputs. Essentially, when an input exceeds this threshold, the system responds or activates. This ensures precise control and avoids false triggers, maintaining proper functioning according to the desired parameters.
