what is sleep apnea?
a disorder where breathing is repeatedly interrupted or paused during sleep
SA: pauses can last a few seconds to minutes and are long enough to (3)
- disrupt sleep
- decrease blood oxygen levels
- increase blood CO2 levels
SA: 3 types of sleep apnea
obstructive, central, complex
obstructive sleep apnea =
- Muscles in the throat relax causing the airway to narrow or close, not allowing enough air in.
- Briefly wakes up to reopen airways
- Most common type
central sleep apnea =
- less common
- brain fails to send signals to respiratory muscles
complex sleep apnea =
when obstructive sleep apnea becomes central sleep apnea
sleep apnea symptoms that happen while asleep (4)
- Breathing that starts and stops
- Frequent loud snoring (more common in men)
- Gasping for air
- Night Sweats
sleep apnea symptoms that may go unnoticed (5)
- Daytime sleepiness and tiredness
- Dry mouth
- Waking up often during the night to urinate
- Difficulty with concentration
- Mood changes
sleep apnea symptoms in women (3)
- fatigue
- headache
- insomnia
7 risk factors of sleep apnea
- Older age: > 40 years old
- Obesity
- Large tonsils narrowing the airways
- Family history and genetics
- Heart or kidney failure: increased fluid buildup in the neck
- Lifestyle habits: alcohol + smoking
- Sex: men more common than women
obstructive sleep apnea is present in what percentage of men and women?
- 33.9% men
- 17% women
obstructive sleep apnea affects 936 million adults between the ages of
30-69
obstructive sleep apnea is most common in what generation?
middle-aged and elderly
what nationalities is sleep apnea most seen in?
hispanics, africans, and asian
history of sleep apnea includes
- Frequent loud snoring, gasping for air /choking in sleep, daytime exhaustion, patient stopping/starting breathing multiple times during their sleep
- Greater than 4 obstructive breathing events in one hour classify pt for the possibility of sleep apnea
mild, moderate, severe sleep apnea =
- Mild: 5-15 events per hour of sleep
- Moderate: 15-30 events per hour of sleep
- Severe: greater than 30 events per hour of sleep
physical assessment of risk factors of sleep apnea =
narrowed airway, measure neck circumference, look for deviated septum
SA: home-based sleep studies pros and cons =
- Pros: cost effective, comfort
- Cons: technician doesn't place leads; thus, may be placed incorrectly,
what is the gold standard with diagnosing SA?
polysomnography
SA: polysomnography =
- Completed in a lab for at least 6 hours
- A minimum of 12 channels of recording electroencephalography, electrooculogram, electromyogram, oronasal airflow, chest wall effort, body position, snore microphone, ECG , and oxyhemoglobin saturation
- heart rate, respiratory abnormalities, gas exchange, heart rhythm, oxygen saturation and muscle tone and contraction are measured
- 1st half= monitoring patients sleeping
- 2nd half = given PAP machine and monitor effects to determine proper settings needed
sleep apnea can increase the risk of (9)
- AFIB
- Pulmonary Hypertension
- Cor pulmonale
- Stroke
- Heart failure
- Type 2 diabetes
- Obesity
- Metabolic syndrome
- Depression
SA: upper airway partially or completely collapses leading to
airflow blockage
- individual will continue to try to breathe despite air not being able to pass through
SA: hypoxia and hypercapnia, causing
- The brain wakes the body to reopen these airways
- This cycle repeats itself dozens of time per night
SA: the constant drops in oxygen supply activate the
sympathetic nervous system
- ↑ HR and ↑ BP
SA: one of the most significant consequences is the risk of Afib, because
- Constant changes in intrathoracic pressure and oxygen levels during apneic events stretch atrial walls and disrupt normal conduction (Leading to Atrial remodeling and arrhythmias)
SA: simple treatment =
lifestyle changes such as quitting smoking, change sleep positions, weight loss
SA: continuous positive airway pressure (CPAP) =
·Treats moderate to severe sleep apnea
·Worn during sleep to prevent apnea and snoring
oDelivers air pressure through mask to keep airways open
·Most people find this device uncomfortable to use: with practice, patients may learn to adjust the tensions on the straps to make it more comfortable
·Could get the Inspire Sleep Apnea Treatment that replaces CPAP
oImplanted device that monitors breathing patterns-> stimulates muscles of the airway during sleep
SA: other possible therapy treatments for sleep apnea
- auto CPAP
- BPAP
- oral appliances
SA: surgical treatments for sleep apnea =
- tissue removal
- tissue shrinkage
- jaw repositioning
- implants
- nerve stimulation
- tracheostomy
SA: PT involvement treatments include
- respiratory muscle training
- postural therapy
- orofacial exercises/myofunctional therapy
vaping associated lung injury (VALI) =
an acute or subacute respiratory illness in which a person's lungs become damaged from substances contained in e-cigarettes and vaping products
VALI: what is a e-cig/vape? how do they work?
- A battery-operated device which heats up an e-liquid within the cartridge
- Liquid is converted to an aerosol
- The aerosol is inhaled/"smoked"/"vaped" by users
VALI: what substances are in vape liquid
- Nicotine
- Propylene glycol
- Formaldehyde - known carcinogen
- Acrolein - herbicide
- Diacetyl
- Diethylene glycol - used in antifreeze
- Heavy metals - nickel, tin, and lead
- Cadmium - metal found also in regular cigarettes
- Benzene - found in car exhaust
VALI: what other complications can happen due to chemical compounds being inhaled?
COPD, bronchiolitis obliterans
VALI: has been found in those who
use a variety of different vaping devices and liquids
- nicotine, THC, CBD
VALI: potentially harmful substances present in vapes include
- Vitamin E acetate (VEA)
- Flavorants
- Volatile organic compounds
- Heavy metals
VALI: what has been highly linked to VALI?
VEA (vitamin E acetate)
VALI: symptoms
SOB, fatigue, fever, cough, vomiting, diarrhea, headaches, dizziness, tachycardia, chest pain, fever, chills, tachypnea, or weight loss
VALI: oxygen saturation will be less than
95%
VALI: patient history =
- use of e-cig devices within the last 90 days
- worsened symptoms over days to weeks prior to seeking care
- decreased exercise tolerance
- predominantly younger male adults - median age being 21
VALI: what type of diagnosis?
exclusion
- ruling out other diagnoses
VALI: what imaging could be used?

VALI: labs show what?
- increased WBC can be found on a lab test of someone with VALI
- blood oxygen levels - low levels indicated lung damage
VALI: what will you see in a CT scan?
- Ground glass opacities
- Consolidation
- Septal thickening
- Provides a sensitive to detection of EVALI
VALI: less common findings in a CT scan
- Subpleural sparing (lung tissue closest to the chest wall is normal but abnormalities are present further in)
- Pleural effusions
- Centrilobular nodularity (a pattern of small white spots signifying underlying lung disease)
VALI: treatment
- cessation of vaping
- rule out other pathologies with antibiotics or antivirals
- corticosteroids - decrease inflammation
- supplemental oxygen
VALI: poor prognosis indicators =
- Age > 35 yo
- Comorbidities compromising pulmonary reserve
- Resting SpO2 >95%
- Continued vaping following admission to the hospital & counseling
