The ratio of ICU beds to the general population is a significant indicator of a country's healthcare capacity. In high-income countries, the number of ICU beds per 100,000 people can be considerably higher than in low-income countries. This disparity reflects variations in healthcare infrastructure, funding, and resource availability. Moreover, efficient management of ICU beds is essential for ensuring that patients receive timely care without overwhelming healthcare providers.

Durability and ease of use are also essential factors in the design of these devices. Smart rollators are often made from lightweight yet sturdy materials, making them easy to maneuver both indoors and outdoors. They are designed to fold easily for storage and transportation, catering to the needs of active individuals who may wish to take their rollator on outings or trips.

One of the primary advantages of standard manual wheelchairs is their versatility. They can be used in various environments, from homes and offices to outdoor spaces. With proper maneuverability, individuals can access public transportation, navigate through crowded areas, and participate in community activities. This versatility helps combat social isolation, ensuring that wheelchair users can lead active and fulfilling lives.
