Which of the following will assist the RT in predicting sleep apnea

Berlin Questionaire

Which of the following is not likely a symptom of OSA

REM

In which stage of sleep is restorative sleep thought to occur

REM

To meet the difinition criteria for sleep apnea, how many seconds of airflow cessation during sleep must be documented

10 seconds

According to the NHLBI, approximately how many Americans suffer from some type of sleep disorder

40 million

In which stage of sleep does the brain show electrical activity similar to wakefulness on EEG tracings

REM

During which stage of sleep are skeletal muscles partially paralyzed, thus greatly affecting ventilation and maintenance of the upper airway

REM

Which of the following is not a physiologic parameter routinely monitored during the PSG study

Right and left arm

If on assessment the Mallampati score is class 4 the patient would be at high risk fro which type of SDB

OSA

Cheyne-Stokes breathing is most closely associated with which type of SDB

CSA

A patient comment regarding the lack of dreaming could mean the patient is not spending a significan period of sleep in which stage

REM

a reduction in airflow between 4% and 50% of the baseline airflow for at least 10 seconds during sleep defines which of th following

Hypopnea

Which of the following diagnostically defines the presence of moderate sleep apnea

AHI 32

Which of the following is not true regarding SIDS

Peaks at 8 months

which of the following is the first sign of SDB

Snoring

NREM occupies

about 75% of the sleep period normally and includes restorative sleep known as delta sleep

REM occupies

25% of the sleep period and is characterized by active brain activity, dreaming, and partial paralysis of skeletal muscles

Sleep architecture represents

the sleep cycles entered during the sleep period. A histogramof the sleep architecture visually depicts the cycling of sleep stages

The role of the RT

is key during rountine patient assessment through questioning the patient's sleeping habits. Although the physical examination may be normal for the SDB patient

Berlin Questionaire

identifies sleep apnea risk factors

ESS

assesses daytime sleepiness

Montage

A sleep study continously records physiologic data fro at least seventeen sources on the patients head and body. The arrangement of thes data on single page is called a montage

The AHI/apnea-hypopnea index

is the primary diagnostic calculation used to confirm the presence of sleep apnea and to classify it according to mild, moderate, or severe

OSA

occurs when an obstruction of airflow in the upper airway causes air movement into the lungs to cease while thoracic-abdominal efforts to breathe continue.

The Mallampati score

can be easily determined through assessment and a class 3 or 4 score is highly associated with OSA

CSA

results from a lack of physiologic stimulation to breathe causing cessation of airflow and is characterized by the absence of thoracic-abdominal efforts

MSA

is a combination of OSA and CSA. When OSA is treated, CSA renaubs tge cause for sleep apnea

Children with OSA

present with different syptoms thatn expected with adults and may include hyperactivity, aggressive behavior, social awkwardness, poor attention span, poor academic performance, or characteristics of attention deficit/hyperactivity disorder

MSA is

combination of OSA and CSA. When OSA is treated, CSA remains the cause for sleep apnea

RT are valuavle assets to the sleep community beause they are a major segmetn of the workforce conducting

sleep studies in SDC's throughout the con=untry and they have a unique background in ventilation, pulmonary anatomy and physiology, pharmacology, and ardiopulmonary dieseas

Although the results of inspetion, palpation percussion, and auscultation during a physical assessment are frequently nonspecfic and may include

EDS, lethargy, poor concentration, obesity, large or short neck, retrognathia/micrognathia, morning headache, loss of memory or concentrtion, recnt weight gain, erectile dysfunction, nocturnal enuresis, pedal edema, or general tiredness regardless oh how many hours of reported sleep

Diagnostically sleep apnea is defined as the cessation of airflow for at least seconds during sleep caused by an obstruction in the airway, a 4% decrease in Spo2, or producing an EEG arousal for at least seconds.

Although patients may be unaware they have sleep apnea, it is likely they have been told they snore.

Snoring is the noise produced during inspiration during sleep as a result of

soft tissue vibration in the palate andpillar regions of the oropharynx and may eventally lead to the developmetn of significant sleep apnea

EDS is

difficulty staying awake during the day. Patients with sleep apnea will be very conscious of the effects of daytime somnolence on their lifestyle.

The ESS is

an eight-term questionaire that measures daytime sleepiness for the initail screening of sleep disorders.

The Berlin Questionaire focuses on

the risk factors associated with sleep apnea and has a high degree of sensitivity and specificity for predicting sleep apnea.

The two major states of sleep,

NREM and REM, cycle back and forth every 60 to 90 minutes for a total of 4 to 5 cycles during a normal 8 hour sleeping period. Usually, sleep begins at stage 1 NREM, progresses to stage 2, followed by stage 3 NREM as sleep deepens. During NREM the brain is in a state of rest while the body can stillmove and respond to stimuli

As REM sleep is initiated,

the brain becomes more active and the body experiences partial skeletal muscle paralysis with changes in ventilation, blood pressure, and heart rate

What is OSA

obstructive sleep apnea

Sleep Disordered Breathing

OSA-Obstructive sleep apnea, CSA-Central sleep apnea, MSA-Mixed sleep apnea

Assessment of Sleep-Disordered Breathing

Epworth sleepiness scale, Berlin Questionaire, The Polysomnogram

Normal Stages of Sleep

Non-Rapid eye movement sleep, Rapid eye movement sleep
