Gases Humidification During Noninvasive Ventilation : Heat and Moisture Exchanger or Heated Humidifier ?

7. maj 2013 opdateret af: University Hospital, Bordeaux

Prospective Study of the Influence of the Humidification Mode on Ventilation Parameters and Arterial Blood Gases in Non Invasive Ventilation

To humidify gases during non invasive ventilation, both to heated humidifier (HH) and heat and moisture exchanger (HME) are routinely used. Patients receiving non invasive ventilation for acute respiratory failure were randomized to HME or HH. The purpose of this study was to evaluate respiratory parameters and arterial blood gases (ABG) of patients during NIV with small dead space HME compared to HH.

Detaljeret beskrivelse

Objective: Few data are reported in the field of noninvasive ventilation (NIV) regarding humidification devices. It was previously suggested that standard heat and moisture exchangers (HME) had adverse gasometrical and clinical outcomes in acute respiratory failure (ARF) of chronic respiratory failure patients (CRF). This study was performed to evaluate respiratory parameters and arterial blood gases (ABG) of patients during NIV with small dead space HME compared to heated humidifier (HH).

Design: Prospective randomized cross-over study. Setting: A 16-bed medical intensive care unit (ICU) and a 14-bed medico surgical ICU.

Patients: Patients receiving NIV for ARF in the context of CRF or hypoxic ARF and patients with persistent weaning failure receiving NIV just after extubation.

Measurements: HME and HH were randomly compared during 2 NIV periods of 30 minutes separated by a 20 to 30 minutes period of spontaneous breathing with oxygen. ABG were collected at baseline and at the end of each period. As well as respiratory parameters including volumes, pressures, P0.1, a comfort score, capnometry and oxygen saturation. Two sets of patients were successively studied whether they have a flex tube added to the ventilatory circuit or not.
