Older adult patients often have poor, fragmented sleep when they are in the hospital. The factors contributing to sleep disturbance in hospitalized elders will be explored, and interventions for promoting sleep among these patients will be discussed.
Sleep-disordered breathing (obstructive and central sleep apnea) is common in persons who have had a cerebrovascular accident (CVA). This article describes both sleep-disordered breathing and CVAs and reviews the related risk factors that link them together. In addition, the article discusses sleep-disordered breathing after CVA. The article concludes by presenting the clinical implications of this topic for nurses.
This descriptive study describes the frequency and severity of sleep-related breathing disorders in men who are hemodynamically stable who have an acute cardiovascular illness and are hospitalized in a critical care unit. Sixty-four males, aged 55-79 years, with an acute cardiovascular illness, stable hemodynamics, and no ongoing chest pain or history of sleep apnea were studied for 1 night in the critical care unit using polysomnography. Forty-seven percent of the sample had an apnea-hypopnea index > or = 5, with events of both obstructive and central etiologies, including Cheyne-Stokes respiration. Oxygen desaturation to < or = 90% occurred in 61% of the sample. There were no episodes of chest pain, ventricular tachycardia, or heart block associated with apneic or hypopneic events; however, dysrhythmias, including sinus bradycardia, supraventricular tachycardia, and premature ventricular beats, were associated with apneic and hypopneic events.
