It consists of an electrically powered heat controlled with a microprocessor to provide software control of the heating element that transfers heat to the water in a chamber. Breathing tubes enable the humidified gas to be transported to the patient which may also be electrically heated (if connected), by means of a heater-wire placed internally to the tubes, to minimize the loss of humidity. A passive electrical adaptor provides electrical energy from the humidifier to the heater-wire in the breathing circuit. Over-current protection is provided by the SMPS inside the inspired™ VHB20 Heated Humidifier, which incorporates an over-current protection that will be triggered (cut-out) if output power of the SMPS reaches 110% of the rating (100W). The SMPS will recover automatically after fault condition is removed, while the humidifier will restart. This safety feature protects the humidifier from short-circuits in the DC part of the circuit, and prevents voltage and current transients on the heater-wire. The inspired™ VHB20 Heated Humidifier provides heated and humidified gas with flow rates of 5 to 60 lpm (invasive) and 5 to 120 lpm (non-invasive). The inspired™ VHB20 Heated Humidifier is a mains powered device that complies with ES60601-1, IEC 60601-1-2, ISO 80601-2-74 and AIM 7351731. {4}------------------------------------------------ ## Principle of Operation: The inspired™ VHB20 Heated Humidifier is a respiratory humidifier that provides a heat source and temperature control to warm a water container, referred as a water chamber, to heat and humidify dry respiratory gases. #### Indications for Use: The inspired™ VHB20 Heated Humidifier is intended to be used to warm and add humidity to gases delivered to patients requiring mechanical ventilation or positive pressure breathing assistance or general medical gases. The inspired™ VHB20 Heated Humidifier is indicated for use by trained personnel only within a hospital/institutional environment. It is compatible with the Fisher and Paykel MR290 Humidification Chamber (Single Use), RT380 Dual Heated Breathing Circuit and RT265 Dual Heated Infant Breathing Circuit. #### Patient Population: Infant to adult patients. #### Environments of use: Hospital/institutional environment We present the proposed device vs. the predicate in Table 1.
