Obstructive sleep apnea Effort but no airflow due to upper airway obstruction
Causes:
-obesity
-tonsillar hypertrophy
-small chin
During sleep, upper airway dilatory muscle relax, allowing narrowing or closure in
one to many sites
** can lead to pulmonary HTN **
Pickwickian syndrome obesity hypoventilation syndrome, daytime sleepiness, snoring
-HIgh CO2 levels
Sleep apnea Repeated episodes of complete cessation of airflow for 10 seconds or longer
Mixed apnea Elements of obstructive and central apnea
Usually begins as central apnea followed by the onset of obstructive apnea
Hypopnea A significant decrease in breathing without complete cessation of airflow
Effort detected with minimal airflow, with or without desaturations
30% decrease in flow with 3% desaturation for >10 seconds
, Central sleep apnea No flow, no chest movement
Cheyne-Stokes respiration
Overlap syndrome COPD patients with coexisting OSA
PaO2 less than 60
and FEV! greater than 30% - COPD patient most likely has obstructive sleep
apnea as well
Hypoventilation syndromes Patients with neuromuscular disorder such as ALS or muscular dystrophy
-Noninvasive is used for treatment
High CO2
Clinical features of Sleep apnea -Tend to be men
- >40 year of age with HTN
-Reported snoring becomes worse
-Tied to sensation of choking, gasping, snorting
-Bad mallampati score
-BMI of 28 cm or above = obesity
Polysomnogram Overnight study required for definitive diagnosis
-Full night - Watched throughout the whole night
-Split night - First half of the night they watch you apnea, second half of the night
you wear CPAP
Shows whether you have obstructive, central or mixed sleep apnea
Central apnea, obstructive apnea, mixed apnea
Apnea hyponea index (AHI) is calculated by AHI = # of apneas and hypopneas / TST hours
Normal: AHI <5
Mild: AHI 5-15
Moderate: AHI 15-30
Severe: AHI >30
Portable cardiopulmonary testing Used to confirm OSA
- Does not record, EEG, EOG, EMG
Advantage: their comfort, convenient, can do it multiple night in a row
Disadvantage: May be set up wrong, no brain waves or eye movements
