Title: [abstract] HIGH CONCENTRATION OXYGEN ADMINISTRATION ON REMOTE LOCATIONS.
Author: Knessl, P; Camponovo, C; Sahinbas, S; Alon, E
Abstract: BACKGROUND: Oxygen administration at FiO2 above 0.8 during the primary resuscitation or on prolonged transfer may pose supply and portability problems. MATERIAL AND METHODS: A lightweight, disposable CO2-absorber equipped "To-and Fro" unit (Intersurgical, Ref. 2136, with adaptations) was evaluated on five female and five male volunteers. The subjective overall distress during the 130 min period has been evaluated by means of 0-100 VAS scale, the physiological parameters (ECG, NIBP, SP02, RR, ax. temperature, breathing gas temperature) of resting subjects and the gas concentrations (FiO2, FetO2, FiCO2, FetCO2) were recorded online. After the initial 10 min. baseline period, the anesthesia type mask was fitted and fixed to the face with straps. Before reducing the O2 flowrate to 0.5 I/min, 10 minutes at 2 I/min, followed by 20 minutes at II/min for denitrogenation were allowed. Another washout phase at II/min (10 min) was interposed after the first hour. RESULTS: The average O2 consumption was 48.6 l/h, including the compensation for leakage. The maximal achieved inspiratory O2 concentration was 95.4% (93.9%), the minimal one 90.1% (81.5%), the values for the male subjects in parentheses. The temperature of the inspired oxygen peaked at 38.0°C (38.3°C). The physiological parameters, including the EtCO2 remained stable, the FiCO2 increased to 0.9% (1.1%) at the end of the trial. The VAS values of subjective discomfort, max. 16.5 (13.2) showed good acceptability (graphics below, mean values).
