Summary
Sleep-disordered breathing (SDB) affects 92% of acute ischemic stroke patients, often linked to factors like BMI, smoking, and atrial fibrillation. Brain infarcts, particularly in the insula, increase SDB risk.
Area of Science:
- Neurology
- Sleep Medicine
- Cardiology
Background:
- Sleep-disordered breathing (SDB) is increasingly recognized as a significant comorbidity in patients with acute ischemic stroke.
- Understanding the prevalence and risk factors of SDB is crucial for improving stroke outcomes.
Purpose of the Study:
- To evaluate the prevalence, structure, and risk factors of sleep-disordered breathing (SDB) in patients diagnosed with acute ischemic stroke.
Main Methods:
- Prospective study of 54 acute ischemic stroke patients.
- Cardiorespiratory monitoring performed on days 2-5 post-stroke onset.
- Assessment of neurological status using NIHSS and modified Rankin Scale (mRS).
Main Results:
- SDB detected in 92% of patients; 88% had obstructive apneas (OA), 12% central apneas (CA).
- SDB severity was not correlated with neurological deficit severity but associated with BMI, smoking, diabetes, and atrial fibrillation (AF).
- Cardioembolic stroke (CES) and insular infarcts were linked to more pronounced SDB and central apneas.
Conclusions:
- SDB is highly prevalent in acute ischemic stroke patients.
- Risk factors include obesity, smoking, diabetes, AF, and specific brain lesion locations.
- SDB, especially in AF patients, may be a marker for respiratory disorders and warrants further investigation.

01:21Sleep Apnea
667
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.

01:30Alterations in Respiration II
2.1K
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...

01:23Acute Respiratory Failure-IV
638
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...

01:27Physical Assessment of the Respiratory Tract II: Inspection
1.1K
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.

2.2K
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.

3.1K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
