[1] Space-geodetic techniques can detect elastic deformation of the Earth caused by atmospheric pressure loading (ATML). However, it has not yet been demonstrated whether these surface displacements should be accounted for at the time of reduction of the observations or by applying time-averaged values to the coordinates after the analysis of the observations. An analysis of the power spectral ...

It is well established that blood pressure (BP) differs markedly between peripheral (brachial) and central arteries (aorta).1 As the pressure wave travels distally from the heart, mean BP and diastolic BP decrease slightly (1 to 2 mm Hg), but a gradual and significant increase of systolic BP (SBP) and pulse pressure (PP) occurs. This phenomenon is called BP amplification.1 The development of co...

BACKGROUND The purpose of this article is to describe the indications, operative technique, outcomes, and systematic review of the literature on the reconstruction of patients with end-stage pressure ulcers using a fillet flap technique. In this technique, the femur, tibia, and fibula are removed from the thigh and leg, and the soft tissue is used as a pedicled, or free, myocutaneous flap for r...

We have computed 3-D displacements induced by atmospheric pressure loading from 6-hourly surface pressure field from NCEP (National Center for Environmental Predictions) Reanalysis data for all Very Long Baseline Interferometry) and SLR (Satellite Laser Ranging) stations. We have quantitatively estimated the error budget our time series of pressure loading and found that the errors are below 15...

Central Pressure and Pulse Wave Amplification in the Upper Limb To the Editor: The important review of pulse pressure (PP) amplification1 was directed at better understanding of central (ascending aortic or carotid) pressure generated from upper limb measurements of cuff arterial pressure and pressure waveforms. One important issue, not addressed by the authors, is how 2 different noninvasive t...

Because extrafibrillar water content dictates extrafibrillar osmolarity, we aimed to determine the influence of intra- and extrafibrillar fluid exchange on intradiscal pressures and stresses. As experimental results showed that extrafibrillar osmolarity affects intervertebral disc cell gene expression and crack propagation, quantification of the effects of changes in intra- and extrafibrillar f...

Which means that SVV (%) ≈ pulse pressure variation (PPV; %) for FloTracTM. With the present mathematical equation, it can be demonstrated that the SVV calculated by FloTracTM (SVVFT) is not infl uenced by Khi, which means that SVVFT calculation does not include eff ective arterial elastance (Ea). Th e originality of Garcia and colleagues’ fi nding is that they realized that when measuring PPV ...

OBJECTIVE To assess the efficacy of pressure volume loop (PV-L) closure as an indicator of adequate endotracheal tube cuff (ETTc) function, and to compare this with commonly used methods of checking cuff pressure. METHODS We conducted a randomized clinical trial at the Department of Anesthesia, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia from October 2011 to February 2...

BACKGROUND Cardiovascular morbidity and mortality was reduced by 25% when blood pressure (BP) was targeted to 120 mm Hg systolic compared with 140 mm Hg systolic in Systolic Blood Pressure Intervention Trial (SPRINT); however, BP was measured using a research technique. SPRINT specified 5 minutes of seated rest in a quiet room followed by 3 oscillometric measurements without an observer in the ...

The function of the arteries as an elastic reservoir between the heart and the capillaries is reviewed. The appropriateness of selecting the exit from this reservoir as the point for estimating its effective pressure is shown. The technique for taking the pressure here by the method of Gaertner is described and its advantage and certain apparent disadvantages are indicated. The technique of Gae...
