Proposed Clinical Flow

  1. Do not use IC rated ventilations to start off with. When Patients need a kind of respiratory support, use CPAP machines with adapted masks (more later)
  2. Free all IC rated ventilation units for those patients who are not (yet) in a critical state (estimated to 6-10%)
  3. Step from CPAP to IC ventilation only for critical situation

Usage of CPAP Devices

Due to the proposed Clinical Flow, there is a need for supply of CPAP ventilation systems, but then with proper masks to ensure a proper pressure in the lungs and to avoid air leakage and thereby further spreading of the virus. In order to do that, four things are needed (reference and numbered in Picture):

  1. A CPAP machine or hospital air supply which creates enough inflow of approximately 13 l/m (to be checked)
  2. A mask with enough sealing so that the incoming airflow will be directed to the lungs and not leak out.
  3. A connector which separates the inflow from the outflow in the mask (see important comments later)
  4. A Filter to prevent contamination in the outflow
  5. A pressure control valve which ensures that the pressure in the lung will not rise to dangerous values; it should stay between 5 upto 50 cm of water
