The Relationship Between Sleep Quality and Hemodynamic Status Among Critical Patients

Abstract

Objective: This study aims to investigate the association between sleep quality and hemodynamic status in critically ill patients admitted to the Intensive Care Unit, focusing on physiological stability and patient outcomes.

Method: A descriptive correlational study with a cross-sectional design was conducted. Sleep quality was assessed using the Richards-Campbell Sleep Questionnaire, while hemodynamic parameters were observed through routine clinical monitoring. The sample included 26 ICU patients who met the inclusion criteria: age ≥18 years, ICU stay of at least 24 hours, and a Glasgow Coma Scale (GCS) score ≥12.

Results: The majority of participants were male (61.5%). Diagnoses included coronary artery disease (42.3%), ST-elevation myocardial infarction (23.1%), congestive heart failure (26.9%), and ventilator-associated pneumonia (7.7%). Over half of the patients had comorbid conditions (53.8%). Poor sleep quality was reported by 38.5%, and very poor sleep by 46.2%. A statistically significant correlation was found between sleep quality and heart rate (p = 0.031).

Conclusion: Heart rate appears to be the most responsive hemodynamic parameter to changes in sleep quality. In contrast, SpO₂ and MAP are more affected by other clinical factors. Continuous monitoring of both sleep quality and heart rate is crucial for optimizing care in ICU patients, especially those with cardiovascular issues.
