The term "internal CPAP" is not a standard medical term. Based on the provided reference, it appears to be referring to an implanted device used to treat sleep apnea, which works differently from a traditional CPAP machine.
Understanding the Implanted Sleep Apnea Device
Unlike a standard CPAP machine that uses air pressure, an implanted device tackles sleep apnea from within the body.
- Nerve Stimulation: The core mechanism involves an implanted device that stimulates the hypoglossal nerve.
- Tongue Muscle Movement: This nerve is connected to your tongue. By stimulating it, the device directly moves your tongue muscles.
- Airway Opening: This targeted movement of the tongue helps to open your airways, preventing the collapse that causes sleep apnea episodes.
This method is a form of upper airway stimulation therapy, offering an alternative for some individuals who cannot tolerate traditional CPAP.
Implanted Device vs. Traditional CPAP
Here's a comparison based on how each method works to keep the airway open, drawing from the provided reference:
| Feature | Implanted Device (Often referred to as "Internal CPAP") | Traditional CPAP Machine |
|---|---|---|
| Method | Nerve Stimulation | Pressurized Air Stream |
| Action | Stimulates the hypoglossal nerve; directly moves tongue muscles | Delivers constant air pressure into the airway |
| Mechanism | Directly stimulates your nerves or tongue muscles | Doesn't directly stimulate your nerves or tongue muscles |
| Goal | Open airways by controlling tongue position | Open airways by holding them open with air pressure |
| Technology | Implanted electronic device | External machine with mask and hose |
In summary, while both aim to open the airway to treat sleep apnea, the implanted device (what might be called "internal CPAP") achieves this by electrically stimulating a nerve to move the tongue, whereas a traditional CPAP machine uses continuous air pressure.
