I bought the medical instruments such as thermometer, blood pressure manometer out of my own pocket.
However, to our knowledge, no study has evaluated the impact of discontinuous control of cuff pressure using a manometer on the incidence of complications related to underinflation or overinflation of tracheal cuff in ICU patients.
With the addition of a micro manometer on the 1.4 F conductance catheter, LV pressure-volume relationships can be generated even in small animals allowing continuous hemodynamic evaluation of LV systolic and diastolic function including contractile and relaxation parameters that are relatively independent of loading conditions [ 17, 18].
However, previous studies showed that the connection of manometer to external cuff is associated with a sudden drop in cuff pressure which might result in microaspiration [62, 63].

One of the prototype devices allowed obtaining mists containing 90 99% of droplets smaller than 1 µm, with the minimum arithmetic and Sauter mean droplet diameters of 1.48 µm and 2.66 µm, and the 2.64 ml/min of droplet flow rate for 3.5 bar manometer pressure of atomizing air.
Subsequently the tourniquet was inflated to a manometer pressure of 350 mmHg [ 18] with a maximum application of 2 hours [ 3, 19].
For the heart rate response to the Valsalva maneuver, the ratio of the longest R-R interval to the shortest R-R interval was checked during forced exhalation into the mouthpiece of a manometer to 40 mmHg for 15 s (2, 14).
The pressure was also measured by attaching a manometer to the exit opening of the drainage bottle.
Although this type of manometer used in this study is one of the most convenient and common tool in literatures, the set and measured endotracheal tube cuff pressures are only accurate to within 1 cmH2O.
