Pneumothorax-II01:27

Pneumothorax-II

120
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
Clinical Manifestations:

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

1.5K
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 Ventilation: Inhalation

3.2K
Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.

Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

206
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Physical Assessment of the Respiratory Tract III: Percussion01:29

Physical Assessment of the Respiratory Tract III: Percussion

216
The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.
Percussion in Respiratory Assessment
Percussion evaluates underlying tissue composition with audible and tactile vibrations,...

Pneumothorax-I01:26

Pneumothorax-I

170
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.

Summary
This summary is machine-generated.

Diaphragmatic elevation affects 11.14% of cardiac surgery patients, often resolving within a year. Topical cold slush is a key risk factor, especially for coronary artery bypass grafting patients.

Area of Science:

  • Cardiology
  • Thoracic Surgery
  • Pulmonary Medicine

Background:

  • Diaphragmatic elevation is a recognized complication post-cardiac surgery.
  • Understanding its incidence, prognosis, and etiological factors is crucial for patient management.

Purpose of the Study:

  • To investigate the incidence, prognosis, and etiology of diaphragmatic elevation after cardiac surgery.
  • To identify risk factors and clinical outcomes associated with diaphragmatic elevation.

Main Methods:

  • Retrospective analysis of 888 cardiac surgery patients (February 2019 - December 2019).
  • Chest X-rays used to detect diaphragmatic elevation.
  • Propensity score matching employed to identify independent risk factors.

Main Results:

  • Diaphragmatic elevation occurred in 11.14% of patients, with 85% recovery within a year.
  • Topical cold slush identified as an independent risk factor, increasing incidence and hospitalization.
  • Higher incidence observed in coronary artery bypass grafting (CABG) patients; associated with diabetes mellitus and left internal mammary artery harvesting.

Conclusions:

  • Diaphragmatic elevation is common after cardiac surgery, particularly in CABG patients with diabetes.
  • Concomitant chronic obstructive pulmonary disease (COPD) and diaphragmatic elevation lead to prolonged mechanical ventilation.
  • Reducing topical cold slush use and considering beating heart surgery may mitigate risks in high-risk patients.
