Studies have showed that long-term sequelae from COVID-19 may affect human respiratory system, cardiovascular system, nervous system, immune system etc. with a negative impact on the patients’ mental health, well-being and quality of life, but the lungs are the organ most likely to sustain serious impairment from COVID-19.

Indirect calorimetry (IC) is the gold-standard for determining measured resting energy expenditure (mREE) in critical illness. When IC is not available, predicted resting energy expenditure (pREE) equations are commonly utilized, which often inaccurately predict metabolic demands leading to over- or under-feeding.

Long-term effects of COVID-19 are of utmost relevance. This study aims to determine the functional capacity of COVID-19 survivors by cardiopulmonary exercise testing (CPET), the characteristics associated with cardiopulmonary exercise testing (CPET) performance and the safety and tolerability of CPET.

COSMED system (Quark CPET, COSMED, Rome, Italy) with an electronically braked cycle ergometer was used.

COVID-19 can rapidly progress into acute respiratory distress syndrome accompanied by multi-organ failure requiring invasive mechanical ventilation and critical care treatment.

A novel study was published on Current Opinion in Physiology to summarise the impact of COVID-19 infection on pulmonary function and to relate this to disease severity and to the clinico-radiological outcomes.
