MAQUET FLOW-I COVID-19 QUICKGUIDE TWO RULES OF FLOW-I 1. Make sure it is switched on 2. READ THE SCREEN FLOW-I Membrane buttons for quick access to special windows on screen eg trends, silence alarms etc Screen with touch Rotary knob for selecting, changing display area for and confirming values on the screen.

USING THE MACHINE Fresh gas flow should be set to 4l min. The is a compromise between low flow (which conserves oxygen, heat and moisture) and high flow (which conserves soda-lime and reduces the build-up of condensation in the circuit) In the case of sudden desaturation, set O2 to 100% Note that the O2 concentration selected may differ slightly from the inspired fraction of oxygen (FiO2) measured at the patient end of the circuit (see next point)
DAILY CHECKLIST Back up cylinder (mounted on the back of the machine) Alternative means of ventilation (Bag Valve Mask) must be kept with every machine Tube clamp A HEPA filter should always be present at the machine end of the breathing circuit on the expiratory limb of the circle breathing circuit.
VENTILATION MODE Patients should be ventilated using Pressure regulated Volume Control (PRVC) unless otherwise specified by an intensivist Triggering of breaths by the patient can be seen by a red line on either the pressure or flow waveforms, or both CONDENSATION PAY PARTICULAR ATTENTION TO THE BUILD-UP OF CONDENSATION IN THE BREATHING CIRCUIT.

PAUSING If a pause of longer than 60 seconds is required then either: (a) Press new pause (b) Select manual ventilation (NB PEEP will be lost – consider clamping the tube) DOCUMENTATION Ensure the following are documented in the ICU records Last machine check (date and time) Last soda lime change (date and time) –...
