Evaluating control of breathing utilizing an on-line microcomputer.
This paper describes a system that was designed to evaluate ventilatory responses to hypercapnia, airway occlusion pressure (P100), as well as measuring ventilatory drive and timing. Parameters measured include minute ventilation (VE), breathing rate (f), tidal volume (VT), inspiratory time (TI), fractional inspiratory time (TI/TTot), mean inspiratory flow (VT/TI), and end tidal partial pressure of carbon dioxide (PETCO2). These measurements allow for a thorough analysis of abnormalities of neural and neuromuscular ventilatory drive. The system's architecture was based primarily on currently available microcomputer components designed for the IEEE 696 bus.

Effect of thoracentesis on arterial oxygen tension.
The acute effects of thoracentesis on arterial oxygenation were observed in 19 studies on 17 patients. Arterial blood samples were obtained prior to, immediately after, and 1 h after thoracentesis. Unpredictable changes in the arterial oxygen tension, ranging from -22 to +19 mm Hg were found immediately following thoracentesis. It was concluded that significant hypoxemia may result from thoracentesis due to aberration of ventilation-perfusion relationships. It is further suggested that oxygen therapy be routinely administered during and immediately after the procedure.
