Cessation of breathing for 20 seconds is known as?

Appeared in: HPSSC Staff Nurse - 2021

Explanation

Apnea is clinically defined as the cessation of breathing for a period of 20 seconds or longer.
Alternatively, a shorter respiratory pause accompanied by significant clinical signs like bradycardia (heart rate less than 100 bpm), cyanosis, or pallor is also considered apnea.
This condition is most frequently observed in premature infants because their central nervous system, which regulates breathing, is not fully developed.

Option A: Respiratory arrest is the complete and prolonged cessation of all breathing activity. It is a life-threatening emergency that does not resolve spontaneously and requires immediate resuscitation.
Option B: Respiratory Distress Syndrome (RDS) is characterized by difficult and labored breathing, not the cessation of breathing. Signs include tachypnea (rapid breathing), nasal flaring, grunting, and chest retractions.
Option D: Transient tachypnoea of the newborn (TTN) involves rapid, shallow breathing (a respiratory rate greater than 60 breaths per minute), which is the opposite of apnea.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of Neonatal Apnea as background academic context rather than a clinical decision trigger.
Nurses in neonatal units must be vigilant in monitoring at-risk infants for apnea, as prolonged episodes can lead to hypoxia and bradycardia, potentially causing brain injury.
It is crucial to differentiate between benign periodic breathing (short pauses followed by rapid breaths, common in infants) and clinically significant apnea that requires intervention.
Nursing interventions for apnea begin with gentle tactile stimulation. If the infant does not respond, more advanced support like positive-pressure ventilation may be necessary.

How to Approach the Question

First, identify the key terms in the question stem: "cessation of breathing" and "20 seconds".
Recognize that this is a definition-based recall question asking for the specific medical term for this sign.
Systematically evaluate each option based on your knowledge of respiratory conditions.
Eliminate 'RDS' and 'Transient tachypnoea' as both involve tachypnea (rapid breathing), the opposite of cessation.
Differentiate between 'Respiratory arrest' (a complete, sustained stop) and 'Apnea' (a temporary pause, often defined by a specific time frame like 20 seconds).
Select 'Apnea' as it precisely matches the clinical definition provided in the question.
