sleep apnea Flashcards
sleep apnea
what is sleep apnea ?
stop breathing while sleeping
Types of sleep apnea
central sleep apnea
obstractive sleep apnea
obstractive sleep apnea syndrome (daytime sx)
gold standard of diagnosising sleep apnea
PSG
AHI
=number of hypopneas+ apnea / total hours of sleep (> 30–severe_
will a single channel research be accepted as a proper diagnosis for sleep apnea ? Y/N
N
at least how many channel will be used for diagnosising the sleep apnea
7
risk factor for sleep apnea
smoking
alcohol
age
obesity
gender
which group of patient is indicated for CPAP
moderate to severe OSA
can CPAP provide continuous postive airway pressure ? Y/N
Y
phenotype of OSA
pcrit / loop gain / muscle responsiveness (muscle tone) / arousal threshold
can COPD overlap with OSA Y/N
Y
treatment options for pcrit
medications that would improve the muscle tone
treatment options for loop gain
carbonic anhydrase inhibitor
PSG contains
ECG / EMG / SpO2 / EOG /EEG / measurement of repiratory and inspiratory
sleep architecture indicates that sleep can be divided into 2 stages
REM / non-REM
what would happen if patient with COPD and OSA remain untreated for their OSA
higher risk od death and higher risk of acute exacerbation
treatment option for low arousal threshold
zolpidem
sedative
for CPAP it could provide a fixed pressure or an autoset pressure (or combination of both) Y.N
Y (autoset is more common
at least 4 hours of use is required to see the effect for CPAP Y/N
Y
both the mask and the tube for the CPAP have a fixed standard, hence, the patient can purchase the marks and tube from different companies Y/N
