Indications for Use

Heated wire circuits to be used with the SCT 3000 are indicated as breathing circuits for patients under going anesthesia or mechanical ventilation.

Device Story

Heated wire breathing circuits and limbs designed for use with SCT 3000 Heated Humidifier; various configurations for anesthesia and volume ventilation; includes breathing tubes, patient wye connectors, and breathing bags; single or dual heated wire options; available for ventilators with or without internal exhalation valves; may be packaged with accessories like filters, face masks, and gas sampling lines. Used in hospital settings (anesthesia, ICU, respiratory therapy) by clinicians. Provides heated, humidified gas to patients to maintain airway moisture and temperature during mechanical ventilation or anesthesia. Single-use device.

Clinical Evidence

Bench testing only. Device meets ASTM breathing systems standards.

Technological Characteristics

Heated wire breathing circuits; single or dual wire configurations; various lengths and styles for anesthesia and volume ventilators. Materials identical to standard breathing circuits (exempt from PMN). Complies with ASTM breathing systems standards. Single-use.

Indications for Use

Indicated for patients, including adults, pediatrics, and neonates, undergoing anesthesia or mechanical ventilation requiring use of the SCT 3000 heated humidifier.

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.
