This guideline is intended for the provider operating in an austere, limited resource setting. Providers have varying levels of knowledge, training, and experience in basic critical care concepts. It is not intended to be all inclusive, but to spur further thinking and identify areas where resource limitations or known diseases specify changes to usual practices. The management strategy described is designed for a 24-hour hold of a single critically ill patient and is tailored to the equipment and medications typically available in austere operational settings (Role 1 and Expeditionary Role 2). Refer to the most updated DoD COVID-19 Practice Management Guide for recommended clinical management, and CENTCOM COVID-19 Playbook for operational considerations.
