Summary
Central sleep apnea (CSA) can emerge after obstructive sleep apnea (OSA) treatment. Positive airway pressure therapy resolved CSA in a patient post-surgery, highlighting the need for long-term monitoring.
Area of Science:
- Sleep Medicine
- Respiratory Medicine
- Otolaryngology
Background:
- Central sleep apnea (CSA) is characterized by a lack of respiratory effort during sleep.
- Treatment-emergent central sleep apnea (TECSA) can occur after treatment for obstructive sleep apnea (OSA).
Observation:
- A 23-year-old male developed CSA following pharyngeal and nasal surgery for severe OSA.
- The patient experienced frequent arousals leading to increased ventilation and high loop gain, contributing to central apneas.
Findings:
- Positive airway pressure (PAP) therapy effectively resolved the patient's CSA.
- PAP therapy likely reduced residual airway obstruction and improved ventilatory stability.
Implications:
- This case underscores the importance of long-term follow-up with polysomnography for OSA patients.
- Identifying patients at high risk for TECSA is crucial for effective sleep apnea management.
- Careful monitoring is essential to ensure the sustained effectiveness of OSA treatments.

128
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.

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).

01:15REM Sleep Behavior Disorder
145
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.

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

159
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
