Sleep disordered breathing in hospitalized patients
1Johns Hopkins University Hospital and Bayview Medical Center Baltimore, MD 21205, USA.
Summary
Sleep disordered breathing (SDB) is common in acutely ill inpatients, affecting 77% of those studied. Higher BMI and female sex were associated with increased SDB severity, particularly in those with heart failure.
Area of Science:
- Pulmonary Medicine
- Sleep Medicine
- Cardiology
Background:
- Sleep disordered breathing (SDB) literature in acutely ill inpatients is limited.
- Assessing SDB prevalence and associated factors in hospitalized patients is crucial.
Purpose of the Study:
- To determine the frequency of SDB in acutely ill inpatients referred for polysomnography.
- To identify patient characteristics associated with SDB in this population.
Main Methods:
- Retrospective chart review of 100 inpatient polysomnograms and medical records.
- Data collected between January 2003 and September 2004 at two tertiary care centers.
- Analyzed associations between SDB and age, sex, BMI, and admission diagnosis.
Main Results:
- A high frequency of SDB (77%) was observed in the study sample.
- Increased body mass index (BMI) correlated with higher odds and severity of SDB.
- Women and patients with decompensated congestive heart failure (CHF) showed significant associations with SDB.
Conclusions:
- SDB is highly prevalent in hospitalized patients undergoing polysomnography, especially those with cardiopulmonary conditions.
- Further research is needed to understand SDB's impact on acute exacerbations of cardiopulmonary disease.

01:30Alterations in Respiration II
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

01:23Acute Respiratory Failure-IV
Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...
01:21Sleep Apnea
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

01:15REM Sleep Behavior Disorder
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

01:26Respiratory Volumes and Capacities I
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
01:27Physical Assessment of the Respiratory Tract II: Inspection
Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.
