Respiratory resistance measured by an airflow perturbation device.
The airflow perturbation device (APD) is an instrument for the measurement of respiratory resistance. The APD is small, lightweight, fast and requires no special breathing manoeuvres. Airflow perturbation determines resistance by superimposing a periodic signal onto spontaneous breathing with a variable resistance device. Respiratory impedance is the ratio of magnitude of pressure perturbation ...
متن کاملDecrease of resistance to air flow with nasal strips as measured with the airflow perturbation device
BACKGROUND Nasal strips are used by athletes, people who snore, and asthmatics to ease the burden of breathing. Although there are some published studies that demonstrate higher flow with nasal strips, none had directly measured the effect of the strips on nasal resistance using the airflow perturbation device (APD). The APD is an inexpensive instrument that can measure respiratory resistance b...
متن کاملTesting Low Doses of Caffeine on Respiratory Resistance Using the Airflow Perturbation Device
Research reports on pulmonary function measurements often mention caffeine abstinence as a condition for testing subjects. Yet, the effects of caffeine on respiration are not well documented. This study was intended to investigate the physiological effects of caffeine on respiratory resistance measurements and the necessity of caffeine avoidance in such testing. Thirty-one subjects were adminis...
متن کاملResistance Measured by Airflow Perturbation Compared with Standard Pulmonary Function Measures
Background: Routine lung function testing requires expensive equipment, or requires maximum expiratory effort. The airflow perturbation device (APD) is a light handheld device, allowing for serial measures of respiratory resistance noninvasively and effortlessly. Methods: In a convenience sample of 398 patients undergoing pulmonary function testing, we compared routine spirometric indices (forc...
متن کاملTesting limits to airflow perturbation device (APD) measurements
BACKGROUND The Airflow Perturbation Device (APD) is a lightweight, portable device that can be used to measure total respiratory resistance as well as inhalation and exhalation resistances. There is a need to determine limits to the accuracy of APD measurements for different conditions likely to occur: leaks around the mouthpiece, use of an oronasal mask, and the addition of resistance in the r...
