See: venturi mask air-filtering respirator An air-filtering respirator is a breathing apparatus which removes particulates from the ambient air by passing it through a filter. air-purifying respirator An air-purifying respirator is a respirator which uses a filter, cartridge, or canister to remove specific air contaminants by passing ambient air through the air-purifying component ...
The process of forcing air into and out of the lungs is known as ventilation. The process by which oxygen is taken in by the bloodstream is called oxygenation. Lung compliance is the capacity of the lungs to contract and expand. The obstruction of airflow via the respiratory tract is known as airway resistance.
Insufflation, also known as 'rescue breaths' or 'ventilations', is the act of mechanically forcing air into a patient's respiratory system. This can be achieved via a number of methods, which will depend on the situation and equipment available. All methods require good airway management to
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.
Intensive care environments around the world revolutionized in 1971 by the introduction of the first SERVO 900 ventilator (Elema-Schönander), constructed by Björn Jonson. It was a small, silent and effective electronic ventilator, with the famous SERVO feedback system controlling what had been set and regulating delivery.
Continuous positive airway pressure (CPAP) is a form of positive airway pressure (PAP) ventilation in which a constant level of pressure greater than atmospheric pressure is continuously applied to the upper respiratory tract of a person.
1831, Charles Thackrah described a "Pulmometer" similar to that of Kentish. He portrayed the device as a bell jar with an opening for the air to enter from below. There was no correction for pressure. Therefore, the spirometer not only measured the respiratory volume, but also the strength of the respiratory muscles. [2]
The whispered pectoriloquy test is similar to bronchophony, but not so much egophony. [2] In bronchophony, the physician often asks the patient to say "ninety-nine" or "baseball" while listening over a lung field with a stethoscope. The spoken word sounds will be louder in areas where consolidation is present.
