To provide recommendations and standard operating procedures for intensive care unit and hospital preparations for an influenza pandemic or mass disaster with a specific focus on essential equipment, pharmaceuticals and supplies.Based on a literature review and expert opinion, a Delphi process was used to define the essential topics including essential equipment, pharmaceuticals and supplies.Key recommendations include: (1) ensure that adequate essential medical equipment, pharmaceuticals and important supplies are available during a disaster; (2) develop a communication and coordination system between health care facilities and local/regional/state/country governmental authorities for the provision of additional support; (3) determine the required resources, order and stockpile adequate resources, and judiciously distribute them; (4) acquire additional mechanical ventilators that are portable, provide adequate gas exchange for a range of clinical conditions, function with low-flow oxygen and without high pressure, and are safe for patients and staff; (5) provide advanced ventilatory support and rescue therapies including high levels of inspired oxygen and positive end-expiratory pressure, volume and pressure control ventilation, inhaled nitric oxide, high-frequency ventilation, prone positioning ventilation and extracorporeal membrane oxygenation; (6) triage scarce resources including equipment, pharmaceuticals and supplies based on those who are likely to benefit most or on a 'first come, first served' basis.Judicious planning and adoption of protocols for providing adequate equipment, pharmaceuticals and supplies are necessary to optimize outcomes during a pandemic.
