NURS 245 Lecture Notes - Lecture 17: Pulmonary Heart Disease, Pulmonary Embolism, Blood Gas Tension
Document Summary
Lecture #17 pt 2: respiratory system (course pack #17) Effect of respiratory disorders: inadequate gas exchange. Coughing up blood from lungs; light red (cid:1543) right sided failure due to respiratory failure (cid:1543) diffusion for co2 is 20x faster than for. O2, therefore at any given change, o2 will be affected first. Using local control (cid:1543) diseases balanced continuously disrupt balance causing cor pulmonale (cid:1543) abnormally low level of oxygen in the blood (cid:1543) condition of abnormally elevated (high) carbon dioxide levels in the blood. D = diffusion coefficient specific for gas. If the walls of the alveoli were broken down, the surface area for diffusion would decrease. The vascular surface area needs adequate blood flow. (cid:1542) hpc, right side heart failure (cid:1543) against pulmonary edema. Hpc, left heart failure (cid:1543) pulmonary edema. Acid base balance: metabolic acidosis if hypoxemia is extreme. Cns suppression at paco2 > 70 mmhg. Effects of chronic ventilatory disorders: cor pulmonale.
