Breathing01:05

Breathing

60.4K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

1.8K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Pulmonary Embolism I: Introduction

50
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

338
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Pneumothorax-I01:26

Pneumothorax-I

353
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

371
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Summary

Pulmonary interstitial emphysema (PIE) in newborns is a rare air leak. Conservative treatment showed good short-term outcomes, but long-term follow-up revealed persistent lung sequelae.

Area of Science:

  • Neonatal Medicine
  • Pediatric Pulmonology
  • Respiratory Medicine

Background:

  • Pulmonary interstitial emphysema (PIE) is a rare air leak syndrome in neonates.
  • Characterized by air escaping the tracheobronchial tree into lung tissue.
  • Often presents as worsening respiratory distress in newborns.

Purpose of the Study:

  • To report on three cases of PIE in moderately premature newborns.
  • To describe the clinical presentation, treatment, and outcomes of PIE.
  • To highlight the importance of medium- and long-term follow-up.

Main Methods:

  • Case series observation of three newborns with PIE.
  • Initial presentation and clinical course documented.
  • Conservative management including positioning and oxygen therapy utilized.
  • Medium- and long-term outcomes assessed clinically and radiologically.

Main Results:

  • All three patients were moderately premature.
  • Initial presentation was respiratory distress, which worsened.
  • Conservative treatment led to clinically symptom-free patients.
  • Follow-up CT scans showed persistent sequelae bullae.

Conclusions:

  • Conservative management appears effective for PIE in neonates.
  • Persistent radiological sequelae, such as bullae, can occur.
  • Systematic medium- and long-term follow-up is recommended to monitor for respiratory symptoms and radiological changes.
