Constipation is a common complication identified among critically ill patients. Its incidence is highly variable due to lack of definition of such patients. ⋯ Ogilvie syndrome, a major cause of morbidity and mortality in intensive care units was also reviewed. Considering the above cases it was concluded that more attention to this disorder is required in intensive care units as well as development of protocols for diagnosis and management of critically ill patients.

Breathing pattern in weaning patients: comparison of two inspired oxygen fractions.
An inspired oxygen fraction (FiO2) of 40% is often used for weaning patients, but lower FiO2 values are also recommended, if arterial oxygen pressure (PaO2)/ FiO2 >150-200 mmHg. This study aimed to compare respiratory variables and vital data values recorded during use of sufficient FiO2 (ideal) to maintain peripheral oxygen saturation at 92% with values recorded during use of FiO2 established at 40% (baseline) in weaning patients. ⋯ These results suggest that FiO2 levels sufficient to ensure a SpO2>92% did not alter breathing patterns or trigger clinical changes in weaning patients.
