terminology for sleep apnea

Post by mckooi » Tue Aug 28, 2007 6:28 pm

Hi,

Is there a site for sleep apnea terminologies? One of the hardest part to learn is to understand all the new terminologies....shall we start one to help those ramp up the learning curve. Please fell free to add in. the list below in alphabetical order just the teminology and short explanation. Please feel free to add in. Thank you

Terminology-Explanation-(Example)
=========================

A-Flex-Auto Flexible (Example:CPAP machine's air supply auto-adjust function).
AHI-Apnea/Hyperapnea Index (Total in an Hour).
Apnea-Block?
BP-Blood Pressure (Example:Systolic/Distolic?)
C-Flex-Contineous Flexible?
CPAP-Continuous Pressure Air P?
FF-Full Face Mask.
HBR-Heart Beat Rate (Per Minute).
SA-Sleep Apnea.
OSA-Obstructive Sleep Apnea.
O2-Oxigen.
Oximeter-Oxigen level detector.
Zzzz-Sleeping.


Regards,
Mckooi

Stuff seen on a PSG Report:

Arousal: An interruption of sleep lasting greater than 3 seconds.

BR Arousal index: The number of breathing related arousals(apnea, hypopnea, snoring & RERAs)multiplied by the # hours of sleep.

Bruxism: Grinding of the teeth.

Central apnea: A respiratory episode where there is no airflow and no effort to breathe lasting greater than 10 seconds.

EEG/EOG: Comments about sleep stages, brain waves (EEG), or eye movements (EOG)

EKG/ECG: Comments about heart rate, abnormal heart beats, etc.

EMG: Comments about leg movements and or teeth grinding (bruxism).

Hypopnea: A respiratory episode where there is partial obstruction of the airway lasting greater than 10 seconds. Also called partial apnea or hypo-apnea.

Non-supine: Sleeping in any position other than on the back.

NSR: Normal sinus rhythm.

NPSG: Nocturnal Polysomnogram, or sleep study.

(#)Number of Awakenings: The number of pages scored as wake after sleep onset.

Obstructive apnea: A respiratory episode where there is a complete cessation of airflow lasting greater than 10 seconds.
PLMs: Periodic limb movements.

PLM arousal index: The number of periodic limb movements that cause arousals multiplied by the number of hours of sleep.

PSGT: Polysomnographic technologist.

REM latency: Latency to REM(dreaming) from sleep onset.

RERAs: Respiratory effort related arousals. Episodes that are not apneas or hypopneas, often related to loud snoring, that generally do not cause a decrease in oxygen saturation.

Respiratory: Any specific comments about respiratory events.

RPSGT: Registered polysomnographic technologist.

Sleep efficiency: Total sleep time multiplied by time in bed.

Sleep latency: The first 30 seconds (one `epoch' of recording time) of sleep.

Sleep onset: The first 90 seconds (3 `epochs) of uninterrupted sleep.

Sleep stage shifts: The number of incidents of sleep stage changes.

Snoring intensity: Level of snoring loudness determined by the sleep technologist. Ranging in degrees from mild to very loud snoring.

Spontaneous arousal index: The number of spontaneous arousals (e.g. arousals not related to respiratory events, limb movements, snoring, etc) multiplied by the number of hours of sleep.

Stage 1: The lightest stage of sleep. Transitional stage from wake. top

Stage 1 shifts: The number of times the sleep stage changed to stage 1.

Stage 2: The first true stage of sleep.

Stages 3/4: The deepest, most restorative sleep.

Stage REM: The dreaming stage; Normally occurs every 60-90 minutes.

Supine: Sleeping on back.

Time in bed: The time in the study from `Lights Out' to `Lights On'.

Total arousal index: Total number of all arousals multiplied by the number of hours of sleep.

Total # of PLMs: The number of leg movements in sleep that last greater than 0.5 seconds.

Total sleep time: Total time asleep.

WASO: Wakefulness after sleep onset.

WNL: Within normal limits.

someday science will catch up to what I'm saying...
