P008 Sleep in the ICU: comparing PSG & structured observation Open
Introduction Patients in Intensive Care Units (ICU) frequently suffer from disturbed sleep and are often prescribed sleep-promoting medications. Assessing the effectiveness of these medications in the ICU by polysomnography (PSG) is diffic…

P084 Does OSA endotype impact the incidence of atrial fibrillation and the severity of atrial remodelling? A retrospective cohort study. Open
Background Multiple studies have suggested that the prevalent sleep disorder obstructive sleep apnoea (OSA) plays a key role in initiating and progressing atrial fibrillation (AF) as well as impacting the response to arrhythmia pharmaco- a…

P098 A rare case of immunotherapy induced narcolepsy with cataplexy. Open
Background Narcolepsy is a rare disorder of central hypersomnolence which is often under diagnosed largely owing to a variable clinical phenotype. There is strong evidence that type 1 narcolepsy (NT1) is an immune-mediated disorder given t…

P055 Impact of humidification on bacterial filters and delivered pressures of PAP devices Open
Background In typical sleep laboratories, PAP devices are used on multiple patients in short periods of time. Some manufacturers recommend the use of bacterial filters to prevent cross contamination. Bacterial filters are known to increase…

P007 Evaluating concordance of actigraphy and sleep-diaries in a clinical setting Open
Introduction Actigraphy and sleep diaries are recommended by both the ICSD-3 and AASM. However, actigraphy provides a significant operational burden. We aimed to evaluate concordance between these tests. Methods 60 sleep studies with concu…

P089 12 month experience of a subsidised mandibular advancement splint program. Open
Background Obstructive sleep apnoea (OSA) is a common condition with the potential for significant morbidity and mortality. Mandibular advancement splints (MAS) are an alternative to continuous positive airway pressure in appropriately sel…

P033 Validation of GENEActiv actimeters and Cicada Actigraphy Suite in a clinical sleep laboratory setting. Open
Introduction The use of Actigraphy in clinical settings is an established approach, with the American Academy of Sleep Medicine (AASM) describing actigraphy as a suggested aid in the diagnosis of multiple sleep disorders such as delayed sl…

O057 The Impact of Surgical Weight Loss on the Physiological Endotypes causing Obstructive Sleep Apnea Open
Background Weight loss improves upper airway collapsibility in people with obstructive sleep apnoea (OSA). However, it’s unclear how weight loss affects the other endotypes responsible for OSA (loop gain, arousal threshold and muscle compe…

P036 Rapid oscillatory ventilation seen during positive airway pressure titration studies: A case series Open
We have observed a phenomenon in some patients undergoing positive airway pressure implement/titration studies in our sleep lab, characterised by periods of extremely high respiratory rates of up to 80 breaths/min which appear to be device…

P159 Successful treatment of sleep disordered breathing improves comorbidities in patients with nocturia Open
Introduction Sleep disordered breathing (SDB) has been shown to increase nocturia (waking with the need to void urine) frequency. Nocturia negatively affects sleep, autonomic dysfunction, mental health and mortality. Nocturia and these co-…

O045 Anxiety and daytime sleepiness scores have a weak but statistically significant correlation with apnoea-hypopnoea index Open
Background Previous datasets demonstrate inconsistent relationships between apnoea-hypopnoea index (AHI) and questionnaire measures of daytime sleepiness, anxiety and depression. Methods 1149 consecutive diagnostic polysomnograms at a quat…

P138 Nocturnal oxygen desaturation and MET call criteria during in-laboratory sleep studies Open
Introduction Patients undergoing sleep studies can experience frequent and profound oxygen desaturation. Most hospitals have standard MET (Medical Emergency Team) call criteria which obligate a response to severe oxygen desaturation. At ou…

The effectiveness of a novel sleep clinical pathway in an inpatient musculoskeletal rehabilitation cohort: A pilot randomized controlled trial Open
The sleep clinical pathway did not improve sleep quality compared with standard care. Larger studies and studies with alternate methodology such as "cluster randomization" are needed.

Sleep apnoea in heart failure: To treat or not to treat? Open
Heart failure ( HF ) and sleep apnoea are common disorders which frequently coexist. Two main types of apnoea occur: one is obstructive which, through recurring episodes of snoring, hypoxaemia, large negative intra‐thoracic pressures and a…
