Well test needs to measure pressure changes under the condition of well shut-in, which will influence regular production.
The difference in the time of maximal hyperaemic response between the Framingham study and our report might be related to the fact that finger PAT measures pressure changes while PPG measures changes of the relative amount of blood volume.
In the selected papers drift was assessed by two methods: a) verifying the pressure read by the catheter at atmospheric pressure once it was removed from the patient [ 8, 9]; and b) measuring pressure changes over time in an artificial hydraulic model [ 10, 11].
We measured cuff pressure changes at the expiratory pauses for roughly 30 seconds at each position.
We measured airway pressure changes stimulated by exogenously infused ACh to represent airway responses expressed as APTI, a widely used parameter to quantify AHR (Ewart et al. 1995, 1996; Grinnan et al. 2006).
It is frequently used in the fields of aerodynamics, plasma physics and heat transfer to measure pressure, density, and temperature changes in gases.
The change in pore pressure in the surrounding strata during mining has a direct link with the type of strata fractures, making it possible to estimate the extent of various fracture zones by measuring water pressure changes.
The majority of studies on this subject have inferred a circulatory role after measuring hemolymph pressure changes associated with abdominal contractions using invasive techniques that physically inserted probes into the hemocoel or techniques that detected outer cuticular movements [22], [23], [26].
We included 31 trials measuring blood pressure changes (figures 4 and 5).
To monitor sniffing activity, we implanted a pressure sensor in nasal dorsal medial meatus of 12 rats, allowing us to measure the pressure changes between inspired and expired air (Fig. 1A).
