The pandemic led to unprecedented increases in healthcare delivery costs, widespread disruption in medical supply chains, workforce instability, and a loss of typical inpatient caregiver support. These challenges affected all levels of care, from primary health services to highly specialized intensive care units (ICUs). Before vaccines were available, ICUs were overwhelmed by critically ill patients requiring mechanical ventilation, saturating capacity and straining staff.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>This article seeks to examine the effect that COVID-19 had on ICUs globally, acknowledging its impact with an aim to identify solutions that can be used to help mitigate the overburdening of this limited resource in future pandemics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A narrative review approach was used, drawing on published literature, observational data, and institutional responses from 2020 to 2025, to analyze structural, operational, and clinical adjustments in ICU design and function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Key adaptations included physical redesigns, rapid infection-control upgrades, the use of negative pressure rooms, expansion of tele-ICU systems, and virtual family engagement strategies.
