About

The study evaluates the effectiveness of ear plug, eye mask and ocean sound on sleep quality among ICU patients. 60 patients were randomly allocated to group 1 and group 2 by lottery method i.e 30 in each group. Group 1 received earplugs and eye masks on the first night followed by washout period on second night and received ocean sound on third night, while the group 2 received ocean sound on the first night followed by washout period on second night and received earplugs and eye mask on third night.

Full description

a comparative study was done to assess the effectiveness of ear plug, eye mask and ocean sound on sleep quality.

Ear plug used in this study is a foam earplug made from polyurethane with noise reduction rating (NRR=29 dB, SNR=37dB). It is inserted into the ear canal to protect the user's ear from loud noise. The earplug used was manufactured by 3 M occupational health and environmental safety division company of India manufactured in Bengalaru560.Ear plug helps to reduce noise intensity which helps to decrease auditory perceptual processing.

Eye mask used in this study is a delicate dark colored cloth (black and blue) of fabric material, length -18.5 cm, width- 8.5cm, height- 30 millimeter filled with soft cushions like substance inside which cover both eyes and 2 elasticized strap that holds the mask on patients head which prevents incoming light away from patient's eyes and induces a state of pure darkness. The product detail of Eye mask was, model number-SM004 and was ordered from Amazon.Eye mask decreases the intensity of the light which enhances melatonin secretion (involve endocrine system). Additionally, eye mask helps to use of cognator subsystem as eye mask also helps to reduce visual perceptual processing.

Ocean sound is a type of white noise which is a soothing sound of waves crashing on the beach which is provided via ear phone for 30 min. It was delivered via the android application name relax melodies meditation of Ipnos software. Ocean sound is a type of white noise which prevents intense auditory stimuli less capable of stimulating the cerebral cortex during sleep which helps to decrease auditory perceptual processing.
