Using the ECU4™ to Create Airborne Infectious Isolation Rooms
Frequently Asked Questions
Why is the ECU4™ the best choice for creating short-term airborne infectious isolation of patients
and casualties of a bioterrorism event or other public health care emergency?
1. Safety and CDC compliance. According to the information provided by the Centers for Disease
Control and Prevention (CDC) in its Guidelines En
Facilities (MMWR, Vol. 52, June 6, 2003), the safest way to create airborne infectious isolation for patients
is through the use of a negative-pressure anteroom configuration. Many health care facilities do not have
adequate isolation room capacity for emergency situations, and the ECU4™ quickly and safely resolves
this challenge by creating a negative air lock between a standard medical/surgical room and the corridor
that provides a barrier to prevent contaminated particulates from leaving the room and entering the
corridor.
2. Speed and ease of use. The ECU4™ offers a more timely, flexible and cost-effective alternative to
building fixed anterooms by providing a portable, collapsible solution that can be deployed quickly
within the facility or conveniently distributed throughout the region. The ECU4™ safely converts a
standard patient room into a short-term isolation unit in minutes. From a collapsed position, it can
be set up easily and attached to the patient room door frame. Connecting a HEPA- ltered negative
air machine completes the process.
3. Multiple benefits and cost-efficiency. The ECU4™ is a multifunctional containment tool that can
provide a cost-effective solution for the entire health care organization. Unlike some emergency response
equipment, the ECU4™ doesn't have to sit idle in a corner of a storage space. It has
been designed to be used by the maintenance, engineering, and construction sta s and trades to
safely contain airborne particulates when performing dust producing activities in patient-occupied areas.
Everyday usage not only lowers the cost of purchase and increases the return on investment, but also
reinforces training and improves emergency response capability.
How does the ECU4™ compare to other portable technologies that
are placed inside the patient room?
The ECU4™ is the safest method of providing short-term airborne infectious isolation because it
simultaneously protects the patient, caregiver and general patient population from infectious
airborne particulates. By positioning the ECU4™ immediately outside an infectious patient room, three
advantages are created. First, the two doors of the anteroom enable one to remain closed at all times,
thus preventing infectious airborne particulates from escaping. Second, the negative air pressure source
in the anteroom will redirect the air ow of both the hospital corridor and the patient room into the
anteroom, creating a functional air lock. Finally, an anteroom provides a protected area for caregivers to
don and remove personal protective equipment (PPE), such as gowns, masks, etc. Portable air scrubbers
placed inside an infectious patient room may allow airborne infectious particulates to escape the draw
of the machine, either through disturbances in the air ow, such as an ambulatory patient, or when a
caregiver enters or exits the room. This method does not provide a separate area to protect the caregiver
and external environment when donning or removing PPE. There is an additional risk that portable air
scrubbers may create a positive pressure environment in the patient room if the return air vent is
blocked o to prevent recirculation of airborne infectious particulates throughout the hospital.
Alternatively, if the discharge (typically over 500 cfm) is ducted into a return air duct designed to handle
much less volume one of two problems will result: (1) the back pressure may cause the unit to circulate
much less air or (2) the extra pressure may push air into surrounding areas, causing the pressure
relationship of these areas to change. The ECU4™ avoids these hazards as well as prevents the alternative
need to discharge air to the outside to create the negative pressure environment. The exterior envelope
of the building should never be breached to duct a device to the outside, a procedure which can cause
moisture, insects and unsightly problems, and in some states may be prohibited by code.
