Summary
This study found a significant link between anaemia severity and sensorineural hearing loss. Moderate to severe anaemia correlates with a higher incidence of hearing impairment, suggesting anaemia management may protect auditory health.
Area of Science:
- Otorhinolaryngology
- Hematology
Background:
- Anaemia is a widespread condition with known cardiovascular and respiratory impacts.
- The effect of anaemia on the auditory system is not well understood.
Purpose of the Study:
- To evaluate pure-tone audiometry in individuals with anaemia.
- To determine the relationship between anaemia severity and hearing impairment type.
Main Methods:
- A cross-sectional study of 100 diagnosed anaemia patients.
- Included general examination, tuning fork tests, and pure-tone audiometry.
- Statistical analysis to correlate anaemia degree with hearing loss.
Main Results:
- 46.8% of moderate and 62.9% of severe anaemia patients had sensorineural hearing loss.
- A significant correlation (p<0.05) exists between anaemia degree and hearing loss.
- Moderate and severe anaemia showed higher hearing impairment rates than mild anaemia.
Conclusions:
- Findings suggest a potential link between anaemia and auditory impairment.
- Early anaemia detection and management may prevent hearing loss.
- Further research is needed to understand mechanisms and interventions.

01:30Equipments Used To Measure Blood Pressure
Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

01:28Special considerations while measuring blood pressure
When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

01:15Heart Sounds
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

01:25Assessment of the Abdomen I: Inspection and Auscultation
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen

01:25Assessment of the Cardiovascular System IV: Auscultation
Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
