Thanks Kath will go get some :) and make him some padding from his xxl t-shirts knew they would come in handy

He just told me that the mask when the pressure is high at full the part of the mask around his nose onto cheek flaps slightly and makes a noise so I think its not sealing correctly and leaking slightly will make sure its tight as comfy tonight and see how he goes

Ive so missed this site cant you tell all the typing im doing ;)

Central apnoeas have significant effects on blood pressure and heart rate in children.

 

Brief central apnoeas (CAs) during sleep are common in children and are not usually considered clinically significant unless associated with oxygen desaturation. CAs can occur spontaneously or following a movement or sigh. The aim of this study was to investigate acute cardiovascular changes associated with CAs in children. Beat-by-beat mean arterial pressure (MAP) and heart rate (HR) were analysed across CAs, and spontaneous and movement-induced events were compared using two-way analysis of variance with post hoc analyses. Fifty-three children (28 male/25 female) aged 7-12 years referred for investigation of sleep-disordered breathing (SDB) and 21 age-matched healthy controls (8 male/13 female) were studied. Children underwent routine clinical polysomnography with continuous blood pressure (BP) recordings. Movement-induced, but not spontaneous, CAs were more frequent in children with mild or moderate/severe obstructive sleep apnoea (OSA) compared with healthy controls (P < 0.05 for both). Movement-induced CAs were associated with significantly larger MAP and HR changes across the event compared with spontaneous CAs. The percentage changes in MAP and HR between late-event and post-event were significantly greater for movement-induced compared with spontaneous CAs (MAP 20.6 +/- 2.3 versus 12.2 +/- 1.8%, P < 0.01; HR 28.2 +/- 2.6 versus 14.7 +/- 2.5%, P < 0.001). This study demonstrates that movement-induced CAs are more common in children with OSA, and are associated with significantly greater changes in HR and BP compared with spontaneous CAs. These data suggest that movement-induced CAs should be considered when assessing the cardiovascular impact of SDB.

Oh Carol..... just remembered something else...... now he's lost the weight his pressures might need adjusting.  Has he had another sleep study since all that weight loss?  Whilst in most cases, loss of weight doesn't cure OSA, it can make a difference to the pressures needed.

Rock...... " This study demonstrates that movement-induced CAs are more common in children with OSA, and are associated with significantly greater changes in HR and BP compared with spontaneous CAs.

That is so interesting I assume its a us study ...... we are so far behind here in the UK how can I take this to there attention and more importantly how do I know if they are affecting his BP and HR overall what long term effects would it have

You truely are fab can you come be our personal sleep tech in chilly scotland :)

 

Kath: No he hasnt Kath its yearly here which is about now but they are so far behind its ridiculous I might call his nurse and chew her ear tomorrow :) thanks for all your suggestions
