Key Terms
| Question | Answer |
|---|---|
| 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 |
