An ICU design conceived by CPG for housing patients with infections that are highly virulent. The HLIU unit is designed to manage people and material flow to prevent contamination.
- Staff flow: Staff don additional PPE in clean area before entering patient’s room. If the staff needs anything, someone would pass it through the pass-thru hatch. Upon leaving the room, they doff the additional PPE, shower and change into clean attire before exiting into the ward.
- Patient flow: Patients are masked and move via designated routes that would later be decontaminated.
- Visitor flow: While visitors are not usually allowed, in special cases where they are allowed to enter (e.g. patient is dying or in a critical condition), visitors may be escorted into the ward and communicate with the patient through a viewing window.
- Material flow: Patient waste is treated in Dirty Utility room & decontaminated in the common Decon room in the ward before disposal.

Air Flow & Pressure
AC systems are designed to reduce infections via air transmission. Controlling pressure regime helps in mitigating the spread of infections. Pressurisation moves potentially infectious particles from the clean areas and pushes them out as exhausted air. Exhausted air is treated with HEPA filters.
Sanitary waste from the patient areas go through dedicated sanitary pipes leading to collection tanks where the waste is pumped in for disinfection. The treated waste is then chemically balanced to the appropriate pH levels for discharge to the public sewer.
