## Frequently asked questions

Q: Do I need a GP referral for a private home sleep test?
A: No. You can book directly without a GP referral. We recommend informing your GP of any diagnosis.

Q: How quickly will I get my results?
A: GMC-registered specialist review within 48 hours for all home studies. PSG within 5-7 working days.

Q: Can I do the sleep test at home?
A: Yes. All studies are home-based. Equipment is posted to you and returned by post. PSG requires a technician home visit for setup.

Q: What is the difference between the Pebble and SMED?
A: The Pebble (GBP250) is a first-line screening study for sleep apnoea. The SMED (GBP450) provides more comprehensive respiratory data. Neither measures sleep staging - for sleep staging, the SMED + EEG (GBP600) is needed.

Q: What conditions require a full PSG?
A: Narcolepsy, REM sleep behaviour disorder, nocturnal epilepsy, complex parasomnia, idiopathic hypersomnia, and presentations where simpler tests have been inconclusive.

Q: Does Grace Sleep offer CPAP therapy?
A: Yes. CPAP therapy is available including full provision (Option A) and mask troubleshooting (Option B). A sleep apnoea diagnosis is required first.

Q: What is the difference between CPAP, APAP and BiPAP?
A: CPAP delivers a single fixed pressure. APAP automatically adjusts pressure breath-by-breath based on airway resistance. BiPAP delivers two pressures — higher on inhalation, lower on exhalation — for patients who struggle against fixed pressure or need ventilatory support. Choice is determined by sleep study results and clinical history. See: https://gracesleep.clinic/sleep-apnoea-treatment/

Q: What is the difference between CPAP and APAP?
A: CPAP delivers a single fixed pressure all night. APAP (auto-adjusting positive airway pressure) adjusts pressure breath-by-breath based on airway resistance — delivering lower average pressure and better tolerance for many patients. Both are equivalent for most OSA. APAP suits variable/positional OSA; CPAP suits consistent moderate-severe OSA. Full guide: https://gracesleep.clinic/cpap-vs-apap/

Q: What is the difference between CPAP and BiPAP?
A: CPAP delivers one fixed pressure on both inhalation and exhalation. BiPAP delivers two — a higher IPAP when breathing in and a lower EPAP when breathing out, which makes exhalation significantly easier. BiPAP is prescribed for CPAP intolerance at required pressure, complex or central apnoea, overlap syndrome, and patients needing ventilatory support. Full guide: https://gracesleep.clinic/cpap-vs-bipap/

Q: How do I get CPAP therapy privately in the UK?
A: Private CPAP does not require a GP or NHS referral. The pathway: home sleep study from GBP250, consultant review and prescription, device dispatched, remote setup, then six structured clinical touchpoints. Full guide: https://gracesleep.clinic/private-cpap-uk/

Q: What sleep therapy does Grace Sleep offer after a sleep apnoea diagnosis?
A: Grace Sleep offers CPAP, APAP and BiPAP therapy — all consultant-prescribed, with remote setup, remote monitoring, and six structured clinical touchpoints across the programme. Mask troubleshooting is available for existing device users. See: https://gracesleep.clinic/sleep-apnoea-treatment/

Q: What insomnia treatment does Grace Sleep offer?
A: CBT-I (Cognitive Behavioural Therapy for Insomnia) - delivered by Louise Berger, one of the UK's most experienced CBT-I practitioners.

Q: Does Grace Sleep assess sleepwalking and parasomnias?
A: Yes. Sleepwalking is a non-REM parasomnia. Most cases are benign and diagnosed on clinical history alone. Video polysomnography is reserved for complex, atypical or dangerous cases, new-onset adult episodes, suspected REM Sleep Behaviour Disorder, or suspected nocturnal epilepsy. Full guide: https://gracesleep.clinic/sleepwalking-parasomnias/

Q: What is the difference between sleepwalking and REM Sleep Behaviour Disorder?
A: Sleepwalking is a non-REM parasomnia arising from deep slow-wave sleep, usually in the first third of the night, with little or no dream recall. REM Sleep Behaviour Disorder arises from REM sleep, usually in the second half of the night, and involves physically enacting vivid dreams because normal REM muscle paralysis is lost.
