What is the role of PFTs in monitoring adverse effects of surgery, drug treatments, radiation therapy, and during hospitalization?

Measurement of various aspects of pulmonary function is a relatively easy, noninvasive, and inexpensive way to gauge the status of the respiratory system. Interest in using these tests to determine risk from medical and surgical interventions stems from their presumed ability to be more sensitive than history or physical examination in detecting underlying lung disease. When coupled with the assumption that early detection of pulmonary abnormalities will lead to alterations in patient management, the ultimate goal of improved patient outcomes becomes very attractive.

Impending paradoxical embolism presenting as a pulmonary embolism, transient ischemic attack, and myocardial infarction.

A 25-year-old man presented with complaints of nonpleuritic, substernal chest pain, dyspnea, and decreasing exercise tolerance. His vital signs were normal, with the exception of an oxygen saturation level of 93% while breathing room air. During his assessment, he developed transient left facial droop, left arm and leg weakness, and an ataxic gait, which lasted 15 min then resolved spontaneously.

Do specialists differ on do-not-resuscitate decisions?

Study Objective: Opinions regarding do-not-resuscitate (DNR) decisions differ between individual physicians. We attempted to determine whether the strength of DNR recommendations varies with medical specialty and experience.

Design: Written survey.
