Indications for Use
The RT380/RT385 'Adult Evaqua 2' dual-heated breathing circuits are intended to deliver humidified breathing gases for administration to an adult patient. The RT385 differs only from the RT380 in that the RT385 is supplied with a ventilator pressure line and connector port. Gases available for medical use do not contain sufficient moisture and may damage or irritate the respiratory tract, or desiccate secretions of patients whose supraglottic airways have been bypassed. Thus humidified gases via a heated breathing circuit may be indicated for patients requiring mechanical ventilation, positive pressure breathing assistance, or general medical gases. These gases may be delivered by facemask or through bypassing the upper airways via an endotracheal tube.
Device Story
RT380/RT385 'Adult Evaqua 2' are dual-heated breathing circuits for adult patients; function as conduits for humidified breathing gases; integrate into respiratory humidification systems. Circuits feature inspiratory and expiratory limbs with embedded heater wires to minimize condensate formation. Expiratory limb utilizes water vapor permeable 'Evaqua 2' technology; foaming technique creates tiny air bubbles in tube walls for thermal insulation and structural robustness. RT385 includes ventilator pressure line and connector port. Used in clinical settings for patients on mechanical ventilation or positive pressure support. Healthcare providers connect circuits to humidification systems to prevent respiratory tract damage or secretion desiccation. Benefits include consistent gas temperature and reduced condensate accumulation. Verified for 14 days continuous use.
Clinical Evidence
No clinical data. Safety and efficacy established via bench testing including condensate performance, humidity performance, pneumatic testing, single fault conditions, patient leakage current, enthalpy, connector strength, duration of use (14 days), shelf life (5 years), and biocompatibility.
Technological Characteristics
Dual-heated breathing circuit; corrugated polymer tubing; heater wires in inspiratory and expiratory limbs; water vapor permeable expiratory limb; foaming technique for thermal insulation and wall robustness; 14-day duration of use; 5-year shelf life.
Indications for Use
Indicated for adult patients requiring mechanical ventilation, positive pressure breathing assistance, or general medical gases via facemask or endotracheal tube to deliver humidified breathing gases and maintain inspired gas temperature.
Regulatory Classification
Identification
A breathing system heater is a device that is intended to warm breathing gases before they enter a patient's airway. The device may include a temperature controller.

#### 5.1 Description
The RT380/RT385 'Adult Evaqua 2' dual heated breathing circuits are classified as 'Breathing System Heater' according to 21 CFR §868.5270.
The RT380/RT385 breathing circuits form part of a respiratory humidification system in which the inspiratory limb delivers humidified gas to the patient and the expiratory limb carries the Heater wires in the inspiratory and expiratory limbs expired gas away from the patient. minimise the formation of condensate.
#### 5.2 Intended use
The RT380/RT385 'Adult Evaqua 2' dual-heated breathing circuits are intended to deliver humidified breathing gases for administration to an adult patient. The RT385 differs only from the RT380 in that the RT385 is supplied with a ventilator pressure line and connector port. Gases available for medical use do not contain sufficient moisture and may damage or irritate the respiratory tract, or desiccate secretions of patients whose supraglottic airways have been bypassed. Thus humidified gases via a heated breathing circuit may be indicated for patients requiring mechanical ventilation, positive pressure breathing assistance, or general medical gases. These gases may be delivered by facemask or through bypassing the upper airways via an endotracheal tube.
{1}------------------------------------------------
#### 5.3 Indications for use
The RT380 and RT385 'Adult Evaqua 2' dual-heated breathing circuits are intended as conduits of breathing gas for ventilation of adult patients, and to maintain the temperature of humidified inspired gas.
#### Technological characteristics comparison 5.4
The new adult breathing circuits (RT380/RT385) have been developed based on the cleared RT265/RT266 infant breathing circuit device. The RT380/RT385 are dual-heated adult breathing circuits that, like the predicate device (RT265/RT266), utilize corrugated polymer tubing, with a heater wire in both the inspiratory and expiratory limb.
The intended use of the RT380/RT385 is the same as that of the predicate device, differing only in the population indicated.
The RT380 and RT385 have a water vapor permeable expiratory limb. Permeability allows water vapor to pass into the environment, minimizing the amount of condensate that might form within the expiratory limb and also minimizing the amount of humidity delivered to a ventilator.
The inspiratory and expiratory limbs of the RT380/RT385 are made using a foaming technique that creates tiny air bubbles in the tube wall. In the case of the inspiratory limb the air bubbles improve the limb thermal insulation properties and thus reduce condensate formation. In the case of the expiratory limb, the air bubbles allow a thick tube wall for robustness against physical damage without compromising the water vapor permeability.
The RT380 and RT385 use the same expiratory limb technology and construction ('Evaqua 2') as the RT265/RT266 expiratory limb, but in an adult sized circuit.
Duration of use for the RT380/RT385 has been verified and labeled for 14 days continuous use, compared with 7 days for the predicate device.
Both the RT380/RT385 and the RT265/RT266 predicate device have been verified and labeled for a shelf life of 5 years.
#### Non-clinical tests 5.5
Verification tests were performed to establish the safety and efficacy of the RT380 and RT385. These included condensate performance, humidity performance, pneumatic testing, single fault conditions, patient leakage current, enthalpy, connector strength, duration of use testing, shelf life verification and biocompatibility. Testing was performed to the same standards as used for the predicate device.
#### 5.6 Conclusion
The RT380 and RT385 are considered to be substantially equivalent to the RT265/RT266 breathing circuit. The comparison of features, performance, materials and intended use demonstrate that the RT380 and RT385 'Adult Evaqua 2' dual-heated breathing circuits are safe and effective for their intended purpose.
