Answer 1

Correct Answer: Eupnoea

Rationale:

Eupnoea refers to the normal, unlabored breathing pattern observed in a healthy individual. It is characterized by a regular rhythm and depth, ensuring adequate oxygen delivery and carbon dioxide removal from the body.
In eupnoea, the respiratory rate typically ranges between 12 to 20 breaths per minute in adults, with smooth and consistent inspiration and expiration cycles. This ensures optimal gas exchange in the lungs for maintaining homeostasis.
Eupnoea is essential for maintaining the body’s acid-base balance and is a key indicator of normal respiratory function. It occurs when there is no respiratory distress or abnormalities like shallow or rapid breathing.

Explanation of Other Options:

Apnoea

Rationale: Apnoea is a condition characterized by the temporary cessation of breathing. It can occur during sleep (e.g., sleep apnoea) or due to other medical conditions. Unlike eupnoea, apnoea represents an abnormal or pathological state of breathing.
Apnoea can cause oxygen deprivation and is often associated with symptoms like fatigue, snoring, or choking during sleep. It requires medical intervention in most cases.

Bradypnoea

Rationale: Bradypnoea refers to abnormally slow breathing, with a respiratory rate lower than the normal range (less than 12 breaths per minute in adults). It may result from conditions like drug overdose, brain injury, or metabolic disorders.
Bradypnoea contrasts with eupnoea as it indicates a disturbance in the normal respiratory rhythm that could compromise oxygen delivery to the body.

Tachypnoea

Rationale: Tachypnoea is defined as abnormally rapid breathing, typically exceeding 20 breaths per minute in adults. It can occur due to fever, anxiety, pain, or respiratory conditions such as pneumonia.
Unlike eupnoea, tachypnoea reflects a deviation from normal breathing patterns, often signaling underlying physiological or pathological stress.

Conclusion:

Eupnoea is the term for normal respiratory rhythm and depth, which is vital for maintaining the body’s physiological balance. The other options—apnoea, bradypnoea, and tachypnoea—represent abnormal or pathological respiratory states that deviate from the norm and often require medical evaluation and treatment.
