Key result
This review describes how obesity alters normal respiratory and cardiovascular physiology and affects outcomes in patients facing critical illnesses.
Why the study?
Obesity is a global epidemic and risk factor for many health problems, posing a significant economic and health burden with complex effects on normal physiology and critical illness outcomes.
This review summarizes how obesity alters respiratory and cardiovascular physiology and affects outcomes in critically ill patients.
Altered physiology in obesity may affect critical care; leaves open outcome controversies including the obesity paradox.
In the last few decades, obesity became one of the world's greatest health challenges reaching a size of global epidemic in virtually all socioeconomic statuses and all age groups. Obesity is a risk factor for many health problems and as its prevalence gradually increases is becoming a significant economic and health burden. In this manuscript we describe how normal respiratory and cardiovascular physiology is altered by obesity. We review past and current literature to describe how obesity affects outcomes of patients facing critical illnesses and discuss some controversies related to this topic.
