PHTY300 Lecture Notes - Lecture 1: Hypercapnia, Infection Control, Pulmonary Compliance
Document Summary
Introduction to the icu environment: who needs to be in intensive care, post-operative care. Support of normal body functions: intubation and mechanical ventilation, cardiovascular support (e. g inotropes) Definition: when the patient loses the ability to ventilate adequately (co2) or to provide sufficient oxygen to the blood and systemic organs: arterial blood gas (abg) analysis. Lung disease is severe enough to interfere with o2 exchange. Hypercapnic: (pump, co2 gas movement, effective minute ventilation, overall ventilation) The respiratory system pump is inadequate and cannot maintain ventilation to eliminate the co2 produced by metabolism. Acute: rapid onset, short course and pronounced symptoms. Chronic: long duration of poor abg values, with (metabolic) compensation: what is the ve, va & does the co2 increased or decreased, nor(cid:373)al (cid:373)ale, post a(cid:271)do(cid:373)i(cid:374)al surger(cid:455, dbe (cid:449)ith the ph(cid:455)siotherapist, pe 2 weeks post discharge. Reduced gas going to areas with perfusion: low lung volume (o2 movement problem)
