Abstract:
One of the congenital abnormalities encountered in newborns is hearing loss. Birth hypoxia, asphyxia, and ischemia have all been implicated as primary causes of early hearing loss or deafness. Prospective study was done on neonates in NICU having APGAR scoring of < 7 in 5th minute or neonates diagnosed with birth asphyxia. OAEs were measured from both ears from 3rd to 5th day in sound-proof chamber. MRI reports of these neonates were collected and analyzed. The neonates who did not clear the 1st OAE testing further underwent a second OAE testing between 10 and 14th days. Results were further plotted. 21.9% of neonates had hearing loss. 28.1% of mothers had infections amongst which 6.3% were of hypothyroidism. 56% of neonates with normal OAE result had normal MRI findings. 71.4% of neonates showing a 'REFER' in OAE had normal MRI reports. 44% of neonates with normal OAE result had abnormal MRI report. 7 neonates who failed 1st OAE underwent secondary OAE testing after 10-14 days. 28.6% of the neonates with abnormal OAE report had abnormal MRI findings. There is no statistical correlation between OAE findings with MRI findings of the birth asphyxiated neonates. (p value = 0.671). Hence, there exists no correlation between hearing loss and birth asphyxia.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
