2013年10月2日 · Sniff Nasal Inspiratory Pressure (SNIP) is an alternative way to measure inspiratory muscle strength that does not require a mouthpiece and uses a fairly natural maneuver. To perform the test one nostril is blocked with a soft probe attached to either a manometer or a transducer.

Body: Background: Single-point measurements of maximal inspiratory pressure (MIP) are frequently used to suggest inspiratory muscle weakness. Although there is substantial disparity among predicted MIP according to specific regression equations, it remains unclear whether those discrepancies impact on the diagnosis of inspiratory muscle ...

2016年8月20日 · The latter has now to be pushed back with the wire replacer designed for the purpose, and by reversing the instrument full and forcible inspiration may be applied with similar results. The tube being graduated, the relation as well as the power of the inspiratory and expiratory efforts may be ascertained.”

2013年9月7日 · US Patent 26754 by Augustus Eckert of Dayton, Ohio. 1860. A non counter-weighted water-seal spirometer. Two of the patentable features were a guide rod (B) to keep the inner bell straight and an air-filled water-tight chamber in the rim of the bottom of the inner bell (buoy, E) that served the same purpose as a counter-w

2017年6月25日 · Spirometer attributed to Dr. Lance and M. Javary. Exactly how it worked is unclear. It may be a lung exercise device.

2014年11月8日 · I had to point out that the inspiratory flows on the loop in question came from the pre-FVC inspiration that started at FRC, not RV, and that we don’t emphasize maximal inspiratory flow at that point in the test, just maximal inspiratory volume and for these reasons the flow-volume loop was not a reliable indicator of inspiratory obstruction.

2012年12月18日 · “The mouthpiece (M) contains eight rubber flap valves, four on the inspiratory and four on the expiratory side. Its dead space, including the flexible attachment to the mouth, was 75 ml Beyond the expiratory valves, a mixing chamber (n) of 3-1/2 L capacity contains an induction motor drive four propeller blades.
