QuestionAnswer
atmospheric pressure absolute (ATA) measure of pressure used in hyperbaric medicine; 1 ATA equals 760 mmHg or 101.32 kPa
bronchopneumonia acute inflammation of the lungs and bronchioles, characterized by chills, fever, high pulse and respiratory rates, bronchial breathing, cough with purulent bloody sputum, severe chest pain, and abdominal extension
bronchopulmonary dysplasia chronic respiratory disorder characterized by scarring of lung tissue, thickened pulmonary arterial walls, and mismatch between lung ventilation perfusion; it often occurs in infants who have been dependent on long
croup infectious disorder of the upper airway occurring chiefly in infants and children that normally results in subglottic swelling and obstruction
cyclic guanosine 3’,5’monophosphate (cGMP) a cellular nucleotide that causes vascular smooth muscle relaxation
exudative relating to the oozing of fluid and other materials from cells and tissues, usually as a result of inflammation or injury
fixed (O2 delivery) oxygen therapy equipment supplies inspired gases at a consistent preset oxygen concentration, also called high flow system
heliox therapy low density therapeutic mixture of helium with at least 20% oxygen; used in some centers to treat large airway obstruction
high flow system oxygen therapy equipment that supplies inspired gases at a consistent preset oxygen concentration
hyperbaric oxygen (HBO) therapy therapeutic application of oxygen that pressures greater than 1 atmosphere, also called hyperbaric oxygenation
low flow system variable performance oxygen therapy device that delivers oxygen at a flow that provides only a portion of the patient’s inspired gas needs, also called variable performance system
neovascularization formation of new capillary beds
neutral thermal environment (NTE) ambient environment that prevents or minimizes the loss of body heat
nitric oxide used as inhaled therapy to reduce pulmonary artery pressure and improve arterial oxygenation
reservoir system oxygen delivery system that provides a reservoir oxygen volume that the patient taps into when the patient’s inspiratory flow exceeds the device flow
retinopathy of prematurity (ROP) abnormal ocular condition that occurs in some premature or low birth weight infants who receive oxygen, previously called retrolental fibroplasia
variable (O2 delivery) oxygen therapy device that delivers oxygen at a flow that provides only a portion of the patient’s inspired gas needs, also called low flow system
