ABC (medicine) Opening the airway with a head tilt-chin lift maneuver. Looking, listening and feeling for breathing. Perform chest compressions to support circulation in those who are non-responsive without meaningful breaths. ABC and its variations are initialism mnemonics for essential steps used by both medical professionals and lay persons ...
Mechanical ventilation or assisted ventilation is the medical term for using a ventilator machine to fully or partially provide artificial ventilation. Mechanical ventilation helps move air into and out of the lungs, with the main goal of helping the delivery of oxygen and removal of carbon dioxide. Mechanical ventilation is used for many ...
1. (medical) Ventilation in which the surface of the thorax is exposed to pressure below the ambient pressure during inspiration. Used as a method of artificial respiration (iron lung). [45] 2. (diving) Breathing where the pressure of the breathing gas at the mouth is lower than the ambient pressure at the thorax.
Carbon dioxide (CO 2) is transferred from returning blood back into gaseous form in the lungs and exhaled through the lower respiratory tract and then the upper, to complete the process of breathing. Unlike the trachea and bronchi , the upper airway is a collapsible, compliant tube.
Respiratory inductance plethysmography (RIP) is a method of evaluating pulmonary ventilation by measuring the movement of the chest and abdominal wall. Accurate measurement of pulmonary ventilation or breathing often requires the use of devices such as masks or mouthpieces coupled to the airway opening. These devices are often both encumbering ...
Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. [1] A machine called a ventilator provides the person air manually by moving air in and out of the lungs when an individual is unable to breathe on their own.
Pulmonary function testing is a diagnostic and management tool used for a variety of reasons, such as: Diagnose lung disease. Monitor the effect of chronic diseases like asthma, chronic obstructive lung disease, or cystic fibrosis. Detect early changes in lung function. Identify narrowing in the airways.
High-frequency ventilation is a type of mechanical ventilation which utilizes a respiratory rate greater than four times the normal value [1] (>150 (V f) breaths per minute) and very small tidal volumes. [2][3] High frequency ventilation is thought to reduce ventilator-associated lung injury (VALI), especially in the context of ARDS and acute ...
