Summary
Continuous positive airway pressure (CPAP) for sleep apnea may cause non-severe voice changes. These voice alterations, including roughness and breathiness, become more apparent after six months of CPAP use.
Area of Science:
- Otolaryngology
- Sleep Medicine
- Speech-Language Pathology
Background:
- Obstructive sleep apnea syndrome (OSAS) affects millions globally.
- Continuous positive airway pressure (CPAP) is a primary treatment for OSAS.
- The impact of CPAP on voice quality is not fully understood.
Purpose of the Study:
- To investigate voice parameter alterations in patients undergoing CPAP treatment for OSAS.
- To assess changes in voice quality at one and six months post-CPAP initiation.
Main Methods:
- A cohort of 70 patients with OSAS and no prior voice issues were enrolled.
- Voice parameters were evaluated using videolaryngostroboscopy, Voice Handicap Index-10 (VHI-10), GRBAS scale, and acoustic analysis.
- Comparisons were made between pre-treatment and one- and six-month post-treatment vocal assessments.
Main Results:
- Significant increases in VHI-10 scores were observed after one month of CPAP.
- After six months, VHI-10, GRBAS scores, jitter, shimmer, noise-to-harmonic ratio, and voice turbulence index showed significant negative changes.
- Voice quality alterations became more pronounced over the six-month treatment period.
Conclusions:
- CPAP treatment for OSAS can lead to non-severe voice quality alterations.
- These voice changes, though not severe, warrant consideration due to the long-term nature of CPAP therapy.

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

01:21Sleep Apnea
686
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.

01:16Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
696
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

Chest Physiotherapy (CPT) is a therapeutic technique used in respiratory care to improve ventilation, clear bronchial secretions, and enhance the efficiency of respiratory muscles. This therapy includes three primary procedures: postural drainage, percussion, and vibration. It can be performed on spontaneously breathing patients and those who are intubated and mechanically ventilated.
Purpose
CPT is primarily used for patients with excessive bronchial secretions who have difficulty clearing...

5.5K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

01:25Hyperpnea and Hyperventilation
3.4K
Hyperventilation refers to a higher-than-normal rate and depth of breathing, often associated with anxiety attacks. This excessive breathing surpasses the body's need to expel CO2, leading to a condition known as hypocapnia - an unusually low level of carbon dioxide in the blood. Hypocapnia can constrict cerebral blood vessels, reducing blood flow to the brain, which may result in dizziness or fainting. Early signs include tingling and muscle spasms in the hands and face, caused by falling...
