Document Summary
Basic airway management: oropharyngeal suctioning, basic airway manoeuvres, airway adjuncts. In order to maintain normal functioning, most tissues of the human body demand a continuous supply of oxygen for energy production. Carbon dioxide is formed as a by-product during this aerobic metabolism and must be eliminated from the human body. The uptake of oxygen and expulsion of carbon dioxide is the primary function of the respiratory system. The respiratory system is composed of the conducting airways, the lungs and the parts of the central nervous system concerned with the control of the muscles of respiration. Cellular survival depends on an appropriate match between oxygen delivery (do2) and oxygen consumption (vo2). Patients suffering critical illness or injury frequently lose the ability to maintain a patent upper airway, thereby compromising ventilation and oxygen. Hypoventilation and especially apnoea are some of the fastest ways to produce hypoxia and subsequent irreversible hypoxic brain injury or death.
