Pressure From Above

The View from Above

Tangential pressure measurements in above-knee suction sockets.

Tangential pressure (TP) , as defined in this study, is that pressure parallel to and located at the socket inner face. The talrgential pressure resultant (TP,) will possess a horizontal component (TP,) directed along an axis perpendicular to the main socket axis and a vertical component (TP,) directed along the main socket axis (see Fig. 1). The plane in which all tangential pressures exist is...

Determination of Central Venous Pressure from Intraocular Pressure

Background: In many clinical situations, knowledge of central venous pressure (CVP) is important.  Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery.  Those with carotid artery or jugular venous diseases as we...

Reversibility of optic nerve damage in primate eyes subjected to intraocular pressure above systolic blood pressure.

It was shown previously that pressure-induced interruption of axonal transport at the optic nerve head is reversible after 8 hours of raised intraocular pressure (perfusion pressure of 25 to 35 mmHg). Here we report experiments on the nature, location, and reversibility of pressureinduced abnormalities of the optic nerve head, including interruption in axonal transport, in eyes subjected to a m...

Lifestyle recommendations reduced blood pressure in patients with above optimal blood pressure.

Patients 810 generally healthy adults who were ≥ 25 years of age (mean age 50 y, 62% women), had above optimal BP (mean systolic BP 120–159 mm Hg and diastolic BP 80–95mmHg during 3 screening visits), were not taking antihypertensive medication, and had a body mass index of 18.5–45.0. Exclusion criteria were regular use of drugs affecting BP; target organ damage or diabetes; use of weight loss ...
