Chest trauma can cause life-threatening injuries to the lungs, heart, and airways. It accounts for 25% of trauma deaths. Key injuries include pneumothorax, flail chest, hemothorax, and cardiac tamponade. Pneumothorax is the accumulation of air in the pleural space and can be simple, tension, or open. Flail chest involves multiple rib fractures leading to paradoxical breathing. Hemothorax is blood in the pleural space and massive hemothorax requires chest tube insertion or thoracotomy for severe bleeding. Prompt diagnosis and management of chest injuries is critical for stabilization.
PNEUMOTHORAX_075811.pptx
Pneumothorax is an abnormal collection of air in the pleural space that separates the lung from the chest wall, which can interfere with breathing and cause lung collapse. There are three main types: spontaneous, traumatic, and tension pneumothorax. Spontaneous pneumothorax occurs without underlying lung disease and is usually caused by a ruptured bleb, while traumatic pneumothorax results from chest wall damage or nonpenetrating trauma. Tension pneumothorax is life-threatening due to increased intrapleural pressure that can compress the lungs and blood vessels. Risk factors include smoking, age, lung disease, and mechanical ventilation. Diagnosis involves physical exam, chest x-ray, and CT
CHEST TRAUMA JANI 2.pptx
This document discusses various types of chest injuries including pneumothorax, haemothorax, flail chest, cardiac tamponade, and tension pneumothorax. It describes the causes, symptoms, diagnosis, and treatment options for each condition. For pneumothorax, it outlines treatment depending on size, including catheter drainage or chest tube insertion. For haemothorax, tension pneumothorax, and cardiac tamponade, immediate decompression or drainage is critical along with treatment for shock. Surgical interventions like VATS or open procedures are described for management of persistent air leaks or failures of non-surgical treatment.
Chest Trauma - Medical and Surgical Treatment.pptx
Chest trauma can occur from blunt or penetrating mechanisms and is classified as such. Signs and symptoms depend on the specific injury but may include pain, difficulty breathing, and decreased breath sounds. Common injuries include rib fractures, flail chest, and pneumothorax. A tension pneumothorax is a medical emergency requiring immediate needle decompression to relieve pressure on the heart and blood vessels. Chest tube placement is the definitive treatment for many chest injuries.
Chest trauma
Chest trauma can represent a major burden and lead to significant morbidity and mortality. Chest injuries require prompt evaluation and management to address life-threatening injuries like tension pneumothorax, hemothorax, and cardiac injuries. The chest is divided into the thoracic cavity containing the lungs, heart, and great vessels which are vulnerable to injury from blunt or penetrating trauma. Common injuries include rib fractures, flail chest, pulmonary contusions, and pneumothorax. Immediate airway control and treatment of life-threatening injuries is essential, followed by management of potential injuries and complications to optimize outcomes.
Pneumothorax & Haemothorax
A pneumothorax is the presence of air in the pleural space, causing partial or full lung collapse. It can be caused by trauma, mechanical ventilation, or ruptured blebs. There are three main types: closed, open, and tension pneumothorax. A tension pneumothorax is a medical emergency where air builds rapidly in the pleural space, compressing the heart and blood vessels. Needle decompression is needed to release trapped air. Hemothorax is the presence of blood in the pleural space, often accompanying an open pneumothorax or lung injury. Diagnosis involves history, exams, imaging, and blood gas tests. Treatment depends on severity but may include aspiration or
pneumothorax-171013103109.pdf
Pneumothorax is defined as air in the pleural space between the lungs and chest wall. It is classified as spontaneous, traumatic, or iatrogenic. A tension pneumothorax occurs when air enters the pleural space during inspiration but cannot escape during expiration, increasing pressure on the lungs and blood vessels. Symptoms include chest pain and difficulty breathing. Diagnosis is made through chest x-ray. Treatment for primary pneumothorax is needle aspiration or tube drainage if symptoms are severe. Secondary and tension pneumothoraces require tube drainage as they can cause respiratory failure. Tube drainage involves inserting a catheter through the chest wall and connecting it to suction to remove air from the pleural space.

Pneumothorax is defined as air in the pleural space between the lungs and chest wall. It is classified as spontaneous, traumatic, or iatrogenic. A tension pneumothorax occurs when air enters the pleural space during inspiration but cannot escape during expiration, causing rising pressure and potential cardiovascular compromise. Symptoms include chest pain and breathlessness. Diagnosis is made through chest x-ray showing increased radiolucency. Small primary pneumothorax may resolve on its own, while secondary pneumothorax requires tube drainage. Tension pneumothorax is a medical emergency treated with needle decompression followed by tube insertion.
Pneumothorax.HR
Pneumothorax is a collapsed lung that occurs when air leaks into the space between the lungs and chest wall. It can be caused by chest injuries, lung diseases like COPD, mechanical ventilation, or ruptured air blisters in the lungs. There are three main types: open pneumothorax involves an open chest wound, closed pneumothorax has no chest wound, and tension pneumothorax traps air in the pleural space. Symptoms include chest pain and shortness of breath. Treatment involves placing a chest tube to drain air and re-expand the lung.
Pneumothorax
Pneumothorax is the presence of air in the pleural space between the lung and chest wall. It can be spontaneous, caused by trauma or medical procedures. Spontaneous pneumothorax is classified as primary, occurring without lung disease usually in young males, or secondary, occurring in older males with underlying lung conditions like COPD. Symptoms include shortness of breath and chest pain. Treatment depends on type and severity but may include needle aspiration, tube drainage, or surgery. Tension pneumothorax is a medical emergency where air builds up in the pleural space, compressing the heart and blood vessels and requiring immediate needle decompression.

Pneumothorax is the presence of air in the pleural space, which can occur spontaneously or due to trauma or medical procedures. It most commonly affects young men. There are two main types: primary spontaneous pneumothorax occurs in those with no lung disease, while secondary occurs in those with pre-existing lung conditions like COPD. Tension pneumothorax is a medical emergency where air enters the pleural space but cannot exit, collapsing the lung. The case scenario describes a stab wound patient brought to the emergency department who is diagnosed with tension pneumothorax based on symptoms and treated with immediate needle decompression followed by chest tube insertion.
Chest trauma
Chest injuries account for 25% of severe injuries and are usually caused by road traffic accidents. The primary survey focuses on the airway, breathing, circulation, disability and exposure to identify and treat immediate life threats like tension pneumothorax. Secondary survey involves a full history, examination and investigations like CXR and CT scan to evaluate injuries. Most chest injuries are managed conservatively but conditions like massive hemothorax or cardiac tamponade may require chest tube insertion or thoracotomy.
ABNORMAL CHEST XRAY in Icu care technology.pptx
Chest X-rays are commonly used to detect abnormalities from trauma. A pneumothorax appears as a lucent area on a chest X-ray from collapsed lung. Trauma can cause pneumothoraces through rib fractures or penetrating wounds allowing air to enter the pleural space. Timely detection of abnormalities on chest X-rays like pneumothoraces is important for diagnosis and treatment.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

chest trauma.pptx
- 1. CHEST TRAUMA Dr. Muhammad Aslam
- 2. INTRODUCTION • Trauma is third leading cause of death but it is first leading cause of death below the age of forty. • 25% of deaths due to trauma are because of chest trauma.
- 3. CLASSIFICATION OF CHEST TRAUMA • Blunt trauma • Penetrating trauma • Compression Injuries. Injuries below nipple are also considered as abdominal injuries as there may be injury to diaphragm and abdominal visceras may herniate into chest cavity.
- 4. CHEST WALL INJURIES • Hematoma • Rib Fracture. • Sternal Fracture. • Flail Chest.
- 5. PULMONARY INJURIES • Pulmonary Contusion. • Simple Pneumothorax. • Tension Pneumothorax. • Open Pneumothorax. • Hemothorax. • Hemo-pneumothorax.
- 6. OTHER INJURIES • Cardiac Temponade. • Tracheo-Broncheal Injuries. • Esophageal Injuries.
- 7. EXAMINATION OF PATIENTS WITH CHEST TRAUMA • Follow protocoal of trauma as; A,B,C,D,E i.e. primary & secondary survey. • Inspection, palpation and auscultation.
- 8. RIB FRACTURES • Rib fractures may cause pulmonary contusion resulting into pneumo or hemothorax. • Fractures on right lower chest may cause liver injury. • Fractures on left lower chest may cause splenic injury • Rib fractures are managed conservatively. Pain is relieved by analgesics.
- 9. FLAIL CHEST –Two or more than two adjacent ribs fracture in two or more places –Serious chest wall injury with underlying pulmonary injury –Paradoxical flail segment movement – Chest tube insersion may be needed if there is hemo or pneumothorax. –Positive pressure ventilation may be needed.
- 10. Simple Pneumothorax • Opening in lung tissue that leaks air into chest cavity • Blunt trauma is main cause • May be spontaneous • Usually self correcting
- 11. Signs & symptoms of Simple Pneumothorax • Chest Pain • Dyspnea • Tachypnea • Decreased Breath Sounds on Affected Side TREATMENT is chest tube insertion & good analgesia.
- 12. TENSION PNEUMOTHORAX – Buildup of air under pressure in the thorax. – Excessive pressure reduces effectiveness of respiration – Air is unable to escape from inside the pleural space – Results in collapse of lung on affected side that results in pressure on mediastium,the other lung, and great vessels
- 13. SIGNS & SYMPTOMS • Severe Dyspnea • Absent Breath sounds on affected side • Tachypnea • Tracheal Deviation • Dilated neck veins
- 14. TREATMENT Needle Decompression • Locate 2nd Intercostal space in midclavicular line • Clean area using aseptic technique • Insert needle in 2nd intercostal space and continue to suck the air then chest tube is inserted.
- 15. OPEN PNEUMOTHORAX • Opening in chest cavity that allows air to enter pleural cavity • Causes the lung to collapse due to increased pressure in pleural cavity • Can be life threatening and can deteriorate rapidly • Wounds are sucking wounds.
- 16. SIGNS & SYMPTOMS • Dyspnea • Sudden sharp pain • Subcutaneous Emphysema • Decreased lung sounds on affected side • Sucking chest wound
- 17. TREATMENT • Apply occlusive dressing to wound • Closure of wound • Insertion of chest tube
- 18. HEMOTHORAX • Occurs when pleural space fills with blood • Usually occurs due to lacerated blood vessel in thorax • As blood increases, it puts pressure on heart and other vessels in chest cavity • Each Lung can hold 1.5 liters of blood
- 19. SIGNS & SYMPTOMS • Tachypnea • Signs of Shock • Diminished Breath Sounds on Affected Side • Tachycardia • Chest tube insertion.
- 20. INDICATION FOR THORACOTOMY • After insertion of chest tube, if 1000cc of blood comes out stat, then 200cc of blood/hr for three hours • If there is esophageal injury • Cardiac temponade
- 21. SAFETY TRIANGLE • Safety triangle is bounded anteriorly by lateral border of pectoralis major, inferiorly at the level of nipple & posteriorly by anterior border of latissimus dorsi. • Chest tube is inserted in 4th intercostal space in mid axillary line.
