Summary
Noise levels in neonatal units (NU) often exceed recommended standards. This study found conversations and handwashing equipment in the morning, and equipment changes at night, were primary noise sources, impacting infant well-being.
Area of Science:
- Environmental Health
- Neonatal Care
- Acoustics
Context:
- Neonatal units (NU) are critical care environments for vulnerable infants.
- High noise levels in healthcare settings can negatively impact patient outcomes.
- This study was conducted in a public institution in Fortaleza-Ceará, Brazil.
Purpose:
- To identify the primary sources of noise in a neonatal unit.
- To measure the sound pressure level in decibels (dB) within the NU.
- To compare measured noise levels against established ABNT (Brazilian Association of Technical Standards) recommendations.
Summary:
- A descriptive study measured decibel sound pressure levels in a neonatal unit across morning, afternoon, and night shifts.
- Noise levels peaked during the morning (80.4 dB) due to conversations and handwashing equipment, and at night (78.1 dB) due to equipment changes.
- The average noise level recorded in the NU exceeded the ABNT-recommended limits.
Impact:
- Findings highlight the need for noise reduction strategies in neonatal intensive care units.
- Elevated noise levels may pose risks to neonatal development and well-being.
- Results provide data for improving acoustic environments in critical care settings.

01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:30Respiratory System Abnormal Finding I: Inspection and Percussion
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

01:23Mechanical Ventilation III: Noninvasive Ventilation
Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

01:31Respiratory System Abnormal Finding II: Palpation and Auscultation
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

01:23Assessment of Respiration
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

01:18Nightmares and Night Terrors
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.
