OSA, or Obstructive Sleep Apnea, is a sleep disorder characterized by repeated interruptions in breathing during sleep due to blocked or narrowed airways. This obstruction can lead to fragmented sleep, daytime fatigue, and other health complications if left untreated. Treatment options include lifestyle changes, CPAP therapy, and in some cases, surgery.

4. INTRODUCTION TO OBSTRUCTIVE
SLEEP APNEA
DEFINITION
Obstructive sleep apnea (OSA) is characterized by episodes of a complete
(apnea) or partial collapse (hypopnea) of the upper airway and associated with
decrease in oxygen saturation or arousal from sleep.
OSA is often classified as mild, moderate and severe according to the
AHI(Apnea-Hypoapnea Index).
A common scheme is 5 to 15(mild),15 to 30 (moderate),
>30 event/h (severe)

5. PREVALENCE
 According to various studies and estimates, the prevalence of OSA in India
ranges from 9% to 13% among adults.
 In India 5% to 10% of people affected by mild OSA.
 In India 2% to 5% of people affected by moderate OSA.
 In India 1% to 3% of people affected by severe OSA.
 In India, as in other parts of the world, OSA prevalence tends to increase
with age, with middle-aged and older adults being more commonly
affected.
 However, OSA occur in younger individuals, including children and
adolescents.

6. ANATOMY OF SLEEP APNEA
 The anatomy of OSA involves various structures in the upper airway:
1.Soft palate and uvula:
The soft palate and uvula can collapse backward during sleep,partially or
completely blocking the airway
2.Tongue:
The tongue can fall back against the soft palate or the throat.
3.Tonsils and adenoids
Enlarged tonsils and adenoids especially in children can contribute to airway
obstruction

7. CONT…
4.Throat muscles:
Relaxation of the muscles in throat and tongue during sleep can lead to the
collapse of these tissues into the airways
5.Nasal passages:
Narrow or congested nasal passages can increase the resistance of airflow,
exacerbating the obstruction.
6.Jaw and oral cavity:
The position of the jaw and the structure of the oral cavity can affect the size
and shape of the airway.
7.Neck size:
A large neck circumference, often associated with obesity, can be risk factor
for OSA as it may indicate excess soft tissue in the throat.

8. CAUSES OF OBSTRUCTIVE SLEEP
APNEA
 Age
 Endocrine disorder or any changes in hormone
 Family history and genetics
 Heart or kidney failure
 Large tonsils and thick neck
 Lifestyle habits
 Obesity
 Gender

9. SYMPTOMS OF OBSTRUCTIVE SLEEP
APNEA
 Loud snoring
 Episodes in which you stop breathing during sleep — which would be
reported by another person
 Gasping of air during sleep
 Awakening with dry mouth
 Morning headache
 Difficulty staying asleep, known as insomnia
 Excessive daytime sleepiness, known as hypersomnia
 Difficult paying attention while awake
 Irritability

10. COMPLICATION OF UNTREATED
OSA
 Cardiovascular problem
 Daytime fatigue and sleepiness
 Metabolic disorder
 Mood disorder
 Memory and cognitive impairment
 Decreased quality of life
 Increased risk of accidents

11. DIAGNOSIS OF OSA
 Physical examination
 Polysomnography (PSG) or sleep study
 Home sleep apnea testing (HSAT)

12. SCREENING AND ASSESSMENT
 To identify the risk of the patient, there are several screening tools they are:
1.Berlin questionnaire
2.STOP-BANG questionnaire
3.Preoperative questionnaire
 STOP-BANG is a easily administrable tool for high sentivity

13. STOP-BANG
SCORE
Patient with score of 0 to 2
will be in low risk of OSA,
whereas the patient with the
score of 5 to 8 will be in
moderate to high risk of
OSA

14. TREATMENT OPTIONS
 We can treat the obstructive sleep apnea in three ways they are:
1.PAP therapy (CPAP)
2.Oral appliances
3.Surgical interventions

15. CONT….

16. CPAP THERAPY
 CPAP is applied to the upper airway act as
a pneumatic splint and prevent the collapse
of upper airway during inspiration.
 Nasal CPAP is first describe in 1981 and
has since first line therapy in OSA
 The device is applied to nasal or oronasal
mask, overnight or sleeping hours at set
positive pressure.

17. SURGICAL INTERVENTION
 There are two types of surgeries
1. Uvulopalatopharyngoplasty(UPPP)
2. maxillomandibular advancement (MMA)

18. UVULOPALATOPHARYNGOPLASTY
(UPPP)

19. MAXILLOMANDIBULAR
ADVANCEMENT (MMA)

20. EXERCISE FOR OSA
 YOGA exercise
1. Nadi shodhana
2. Brahmari
3. Ujjayi breathing
 Myofunctional therapy exercise
1. Push up the tongue
2. Touch the nose
3. Touch the chin
4. Push tongue left
5. Push tongue right
6. Roll tongue
7. Click the tongue
8. Push tongue against the spoon
9. Hold a spoon

21. LIFESTYLE MODIFICATION
 Weight loss
 Exercise
 Avoiding alcohol and sedatives
 Quitting smoking
 Sleeping position
 Establishing a regular sleep schedule
 Elevating the head of the bed
