Control of breathing: neural drive

摘要: Breathing is a complex behaviour, governed by control systems hierarchically arranged to regulate ventilation. Their aim respond optimally the prevailing metabolic needs and various demands on respiratory apparatus. Two aspects can grossly be identified. On one hand, there an automatic system permanently aimed at maintaining arterial pH, O2 CO2 pressures (PaO2, PaCO2) within normal range. This regulation remarkably precise cope with major rapid variations in or oxygen consumption. other disrupt order use non tasks: speech main humans, but also include activities such as singing, swallowing, sucking, sniffing, sneezing, hiccough, vomiting, coughing, yawning, defaecating, straining posture control.
