NURS 245 Lecture Notes - Lecture 18: Shortness Of Breath, Idiopathic Pulmonary Fibrosis, Extracorporeal Membrane Oxygenation
Document Summary
Decrease in o2, is picked up by chemoreceptors that would increase ventilation. In sids, a decrease in o2, decreases ventilation. It is an immature brain response in sids. The dominant control of ventilation is hydrogen ion. Prevents initial partial obstruction and decrease in o2. The air would eventually be absorbed and if the lung is less than 20% collapsed, no further treatment is needed. Can cause scarring that leads to rigidity because of the collagen between the pleura causing restriction on the expansion of lungs. If there is a wound in the lung, some air would come in but if there was a spontaneous closure, it would cause a closed pneumothorax. The wound is open and allows air to come in and out. When the wound opens during inspiration and closes during expiration. The collection of fluid in the pleura. Taking a tube and putting it where the collection of fluid/air in it. Inspiration: air can"t move in because tube.
