Name of the Procedure:

Continuous Positive Airway Pressure Ventilation (CPAP)

Summary

CPAP is a treatment method used to keep the airways open by providing a constant stream of air pressure through a mask. It is commonly used for individuals who have breathing problems during sleep.

Purpose

CPAP primarily addresses obstructive sleep apnea (OSA), where a person's airway collapses, causing interrupted breathing during sleep. The goals of CPAP include improving sleep quality, reducing daytime sleepiness, and preventing serious cardiovascular complications associated with untreated sleep apnea.

Indications

• Obstructive Sleep Apnea (OSA)
• Severe snoring
• Daytime sleepiness or fatigue due to disrupted sleep
• Underlying conditions such as heart failure or chronic obstructive pulmonary disease (COPD) that cause breathing difficulties at night

Preparation

• No specific fasting or dietary restrictions are required.
• It is crucial to undergo a sleep study (polysomnography) to diagnose the severity of sleep apnea.
• Patients may need to adjust medications in consultation with their healthcare provider.

Procedure Description

1. Assessment: Initial setup often includes a fitting session to find a CPAP mask that is comfortable and fits well.
2. Machine Setup: The CPAP machine is set up next to the bed. It includes a motor, a hose, and a mask or other interface device.
3. Mask Fitting: The mask (nasal, nasal pillows, or full-face mask) is placed securely over the nose and/or mouth.
4. Air Pressure Adjustment: The machine is turned on, and air pressure settings are adjusted as prescribed by the healthcare provider. Some machines auto-adjust pressure settings.
5. Monitoring: The patient may be monitored overnight to ensure the machine settings are effective and the patient can use the device comfortably.

Duration

The initial setup and fitting may take about 1-2 hours. However, CPAP is used every night during sleep, which typically lasts 6-8 hours.

Setting

• CPAP therapy initiation and management can occur in a sleep center or at home.
• Follow-up and adjustments can be conducted in an outpatient clinic.

Personnel

• Sleep specialists or pulmonologists
• Respiratory therapists
• Trained technicians for fitting and initial setup

Risks and Complications

• Nasal dryness or congestion
• Skin irritation or sores from the mask
• Aerophagia (swallowing air) leading to bloating
• Rarely, serious complications like mask-induced pressure ulcers

Benefits

• Improved sleep quality
• Decreased daytime sleepiness
• Reduced risk of cardiovascular issues
• Better overall quality of life These benefits are often realized after consistent use over a few days to weeks.

Recovery

• No recovery time is required since there is no invasive procedure.
• Users might take a few nights to adjust to sleeping with the CPAP mask.
• Regular follow-up appointments are essential to monitor progress and make any necessary adjustments.

Alternatives

• Oral appliances designed to keep the airway open during sleep
• Surgical options like Uvulopalatopharyngoplasty (UPPP) or genioglossus advancement
• Positional therapy (avoiding back sleep)
• Lifestyle changes such as weight loss and avoiding alcohol or sedatives

Pros of CPAP: Non-invasive, immediate air pressure adjustment, highly effective Cons of CPAP: Requires nightly use, initial discomfort, ongoing maintenance

Patient Experience

Patients may experience slight discomfort and need time to get accustomed to the sensation of air pressure and wearing the mask. There may be initial challenges in finding the right mask fit. Discomfort can be managed with proper mask fitting, using humidifiers to prevent dryness, and regular cleaning to avoid skin irritations. Over time, most patients find significant relief from their symptoms, leading to improved overall sleep quality.
