Bronchiolar aerosol deposition and clearance.
We have often, and over a long time, thought of the "small airways" as a mystery zone or a quiet zone [1]. Relative to central bronchial generations, the total crosssectional area of each bronchiolar generation is large. Airflow resistance should in consequence be low. Considerable changes due to disease could, thus, occur with little chance of being detected by conventional lung function testi...
متن کاملAerosol properties and lung deposition.
important experiments on total and regional lung deposition for healthy subjects has recently been published by the International Commission on Radiation Protection (ICRP) [2]. The mean values of experimental deposition data are approximated by mathematical expressions, which are then implemented into a computer program [3] that is commercially available on diskette. Since this model is applica...
متن کاملRegional aerosol clearance in smokers and nonsmokers.
alveoli are situated immediately adjacent to small bronchi. While cleansing of these probably would be more readily accomplished I)y the interstitial route proposed, this route does not seem as likely for the majority of spaces which really are as much as 2 or 3 mm from any ciliated epithelium. Grecn replied that when three dimensional ;~natomy is ol~served, shorter routes along the alveolar se...
متن کاملDeposition and clearance of inhaled particles.
Theoretical models of respiratory tract deposition of inhaled particles are compared to experimental studies of deposition patterns in humans and animals, as governed principally by particle size, density, respiratory rate and flow parameters. Various models of inhaled particle deposition make use of approximations of the respiratory tract to predict fractional deposition caused by fundamental ...
متن کاملAppropriate background correction for DTPA aerosol clearance.
Measurement of the clearance rate of inhaled aerosols of 99mTc-diethylenetriamine pentaacetic acid (DTPA) from distal airway to pulmonary capillary is a sensitive technique for the detection of lung injury. As the solute diffuses across the blood-gas barrier, the concentration in circulating blood increases, giving rise to a background signal superimposed on the signal from residual DTPA in the...
