Continuous Positive Airway Pressure

Meaning

Continuous Positive Airway Pressure, or CPAP, is a non-invasive ventilatory support. It delivers constant, mild air pressure through a mask worn during sleep. This calibrated pressure maintains an open upper airway, preventing collapse and ensuring unobstructed breathing.

Context

Physiologically, CPAP primarily addresses sleep-disordered breathing, notably obstructive sleep apnea (OSA). During sleep, throat muscles can relax excessively, causing airway narrowing or closure. The device acts as a pneumatic splint, counteracting relaxation and preserving airway patency throughout the sleep cycle.

Significance

Clinically, CPAP is vital for mitigating adverse health outcomes of OSA. Effective therapy improves sleep architecture, reduces daytime fatigue, and enhances cognitive function. Consistent use aids in managing systemic conditions like hypertension, cardiovascular strain, and insulin resistance, often exacerbated by nocturnal hypoxemia.

Mechanism

CPAP’s core mechanism involves continuous positive pressure air delivery into the upper respiratory tract. This airflow creates a pneumatic cushion, physically holding pharyngeal tissues apart and preventing obstructive apneas and hypopneas. Maintaining a stable airway lumen ensures consistent oxygen flow to lungs and bloodstream, normalizing blood gas levels.

Application

CPAP is a standard therapeutic intervention for individuals diagnosed with moderate to severe obstructive sleep apnea. Patients typically wear a mask connected to a small bedside device nightly. Optimal pressure settings are determined via a sleep titration study. Regular follow-up assesses adherence and addresses user discomfort.

Metric

CPAP therapy effectiveness is quantitatively assessed through clinical metrics. A primary indicator is Apnea-Hypopnea Index (AHI) reduction, measured during polysomnography or from device data logs. Patient-reported improvements in daytime alertness and sleep quality also provide valuable qualitative assessments. Device usage hours are routinely monitored to gauge adherence.

Risk

While generally safe, CPAP therapy presents potential risks, mainly related to user comfort and adherence. Common issues include mask leaks, skin irritation, nasal dryness, and aerophagia. Claustrophobia can also be a barrier. Non-adherence is a significant concern, negating benefits and leaving the patient vulnerable to untreated sleep apnea risks.
