Impact of Sleep Deprivation on Malnutrition in ICU (Intensive Care Unit) Patients

"Polysomnography (PSG) is a comprehensive test used to assess sleep disorders and monitor sleep quality. PSG is typically conducted in specialized sleep laboratories and can simultaneously record various physiological parameters to help doctors diagnose different types of sleep disorders, such as obstructive sleep apnea, insomnia, and periodic limb movement disorder.~The monitored components of PSG usually include:~Electroencephalogram (EEG): Records the electrical activity of the brain to determine different sleep stages.~Electrooculogram (EOG): Records eye movements to identify rapid eye movement (REM) sleep stages.~Electromyogram (EMG): Records muscle activity, typically monitoring the muscles of the jaw or legs.~Electrocardiogram (ECG): Monitors the electrical activity of the heart. Respiratory flow monitoring: Records the flow and frequency of breathing. Oxygen saturation monitoring: Monitors blood oxygen levels using a pulse oximeter."
