Sleep apnoea is a clinical condition in which there is difficulty in respiration during sleep, resulting in sleep fragmentation.
1. Causes: It can be broadly classified into three categories and each of them have different etiology.
A. Obstructive Sleep Apnoea: It occurs due to the lack of muscle tone of palatoglossus and genioglossus during sleep in some individuals (Colledge, 2014). It results in obstruction of the upper respiratory tract and thus the difficulty in respiration. There are multiple risk factors for this condition viz. obesity; smoking; male; elderly (above 50 years).
B. Central Sleep Apnoea: It is a less common variant. It occurs as a result of decrease in the drive to respire due to less stimulation of respiratory center in the brain. The causes are mostly congenital and it indicates genetic pathology like Congenital Central Hypoventilation Syndrome; Arnold Chiari Malformation etc. or it may also indicate trauma to any area of the brainstem in case of recent onset.
Clinical Manifestations: An elderly with Sleep Apnoea will present with the following complaints:
i. Excessive daytime sleepiness: The client generally complains of waking up asleep even after lying on the bed the whole night.
ii. Difficulty in concentration: Due to fragmented sleep, the cognitive ability of the individual decreases and they also present with fatigue; irritability; depression etc.
iii. Snoring: Due to obstruction, there is also abnormal noise that is produced due to turbulence in the air pathway.
iv. Choking/ Gasping during sleep: Intermittent episodes of choking or difficulty in respiration occurs due to obstruction of the airway tract.(Colledge, 2014)
2. Nursing Tips to the client:
A. Reduce weight: Clients are advised to reduce weight if they are obese or overweight.
B. Regular Exercises: Clients are advised to exercise regularly that can help them to develop the resistance in the respiratory muscles and improve breathing (Colledge, 2014).
C. Avoid alcohol or sedatives regularly: They can relax the muscles that can obstruct the airway.
D. Maintain proper sleep schedule: Clients are advised to maintain a disciplinary sleep routine.
E. Elevation of the head side: To prop-up the head using a pillow.
F. Open nasal passages during sleep: Clients are advised to use nasal dilator or breathing strips to keep the airway patent.
G. Avoid caffeine during bedtime
H. Try chewing gum or holding pen between the jaws so that the muscles that keep the mouth closed are tightened.
Avoiding activities that involve concentration like driving; swimming etc.is advised.
