In mechanically ventilated patients, we investigated how positioning the heat and moisture exchanger (HME) at different places on the ventilator circuit affected inspiratory gas humidification. Methods. Absolute humidity (AH) and temperature (TEMP) at the proximal end of endotracheal tube (ETT) were measured in ten mechanically ventilated patients.

The rate of ETT occlusion decreased after changing humidification practices from universal HME use to evidence-based active and passive humidification. ETT occlusion was associated with more tracheostomy and a longer duration of MV and ICU stay.

Patients with hematic secretions, due to risk of coagulation, they may occlude ETT and/or HME, which would increase work of breathing. Patients with adherents and/or copious secretions, we must deliver high humidity (44 mg/L and 100% RH), to prevent the inspired gas from capturing heat and moisture of large caliber airway drying secretions ...

Aug 8, 2006 · Results: Hygrobac S provided significantly higher AH and TEMP at both sites than Thermovent HEPA. Both Hygrobac S and with Thermovent HEPA provided significantly higher AH and TEMP when placed proximally to the ETT.

Aug 12, 2014 · There are 3 types of HME or artificial nose: hydrophobic, hygroscopic, and a filtered HME.

Jan 14, 2022 · CONCLUSIONS: The rate of ETT occlusion decreased after changing humidification practices from universal HME use to evidence-based active and passive humidification. ETT occlusion was associated...

Feb 1, 2006 · In mechanically ventilated patients, we investigated how positioning the heat and moisture exchanger (HME) at different places on the ventilator circuit affected inspiratory gas humidification....

Jul 6, 2024 · HME with humidification efficiency >30mg.H2O/L; connects to a standard 15mm connector on an endotracheal tube; METHOD OF INSERTION AND/OR USE. placed in line between Y-piece of breathing circuit and ETT; OTHER INFORMATION. Benefits. ease of use; light; can retain their ability to humidify for up to 4 days with minimal change in resistance

Methods: The authors assessed the impact of two humidification systems, a heated humidifier (HH) and a hygroscopic-hydrophobic heat and moisture exchanger (HME), on the ETT patency in patients selected to require mechanical ventilation for more than 48 h.
