Document Summary

Diseases: pleural effusion, removal of air, very little drainage. To release air, blood, pus, lymph fluid from intrapleural space. Intrapleural space: drain blood and fluid, used after open-heart and chest trauma. Mediastinal: just below the sternum, drains blood or fluid, prevents accumulation. Chest tube safety guidelines: get a patient baseline. Ashley hawthorne: vitals, lung sounds, respiratory status, observe the water seal for. Intermittent bubbling: rise and fall of fluid. Fluid rises with inspiration and falls with expiration. If patient is on a mechanical vetilator, then inspiration will cause a fall and expiration will cause a rise in fluid: sudden stoppage of chest tube activity may. Indicated: note the expected amount of drainage. Sudden decrease in the amount of chest tube. Sudden increase of >250ml / 1hr: constant bubbling in water seal. Pulmonary infarction, severe inflammation: frank blood indicates hemothorax, pus indicates empyema. Ask a senior nurse to walk you through your hospital"s system.

Susan gets shot and experiences a traumatic pneumothorax. The bullet penetrates through her chest wall and lodges in her left lung. When the paramedic arrives, they find that she is barely able to breathe. Why is this? (include what happens to her intra-alveolar and intra-pleural pressures). In addition, discuss her condition in terms of her:A) transmural pressure gradients across her lung wall and thoracic cavityB) intrapleural fluid cohesiveness forces and whyC) intrapleural pressure and whyD) Would her condition have been different if she had experienced a spontaneous pneumothorax, as a result of a respiratory disease process? How? Why?
