Essay

Analyze the following study according to the criteria set by your instructor:
As reported in the Journal of the American Medical Association, 26 surgeons-in-training were studied to see whether sleep deprivation impaired their patient-care ability. For 18 to 19 days the residents kept a sleep diary and underwent five tests each morning to measure cognition, visual and auditory alertness, and hand-eye coordination. Sleep deprivation was defined as less than 4 hours of continuous sleep in the previous 24 hours, which occurred in 89 percent of the on-duty nights studied. When sleep deprivation occurred, total sleep averaged 3 hours, and the longest uninterrupted sleep averaged 2.2 hours.
Residents did show "trivial" improvement on two tests when they obtained some sleep just before testing, but the researchers said repetitive sleep deprivation did not impair the residents' test performances.
The study "does not support arbitrary recommendations to limit working hours of residents," it was said.

Definitions:

Cochlea

A spiral-shaped cavity in the inner ear that plays a key role in the sense of hearing by converting sound waves into nerve impulses.

Tympanic Membrane

Also known as the eardrum, a thin membrane that separates the external ear from the middle ear and vibrates in response to sound waves.

Auditory Fluids

Liquids found within the ear, vital for the process of hearing; includes perilymph and endolymph.

Ossicles

Small bones, particularly the three in the middle ear (malleus, incus, and stapes) that aid in hearing by transmitting sound vibrations.
