Thermovent T2 Heat and Moisture Exchangers

The Thermovent T2 is a passive heat and moisture exchanger (HME) designed to conserve a patient's own exhaled heat and humidity, then return it on the next breath. For clinicians managing ventilated or intubated adult patients, this matters: the upper airway's natural warming and humidifying function is bypassed once a patient is intubated, and dry, cold gas delivered directly to the lower airway can thicken secretions and irritate delicate mucosa. An HME restores that lost conditioning without electricity, water reservoirs, or heated circuits.

This collection features the Amsino International Thermovent T2 Protex, a sterile, single-patient-use HME built for adult tidal volumes up to 500 mL. It uses a paper hygroscopic media to capture moisture, adds low resistance to breathing at just 0.7 hPa at 1.0 L per second, and includes an integrated suction port on a straight housing — letting caregivers access the airway for suctioning without breaking the circuit and losing accumulated humidity.

A common question is whether the T2 includes a viral/bacterial filter. This particular Thermovent T2 configuration is offered without a filter, so it's suited to situations where breathing-circuit filtration is provided elsewhere or where humidification alone is the clinical goal. Because it's sterile and disposable, it supports infection-control protocols and straightforward single-patient handling in the ICU, operating room, transport, and step-down settings.

When selecting an HME, match the device to the patient's tidal volume range and confirm the connection style fits your ventilator circuit and any inline suction or capnography needs. The straight suction-port design here is a practical choice for adult patients who require regular airway clearance.
