Changes in transmural central venous pressure in man during hyperventilation.
We demonstrated that large amounts of blood shift from the forearm veins during hyperventilation (2). If this effect were generalized in the periphery of the body the volume of blood in the central venous reservoir might increase. An increase in pressure in the central veins would be evidence to support this suggestion. The fall in peripheral venous pressure which occurs during hyperventilation...
متن کاملDetermination 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...
متن کاملIntermittent positive pressure respiration after open-heart surgery.
(1) A description has been given of the use of tracheostomy and IPPR in the treatment of twenty-five cases suffering from respiratory and circulatory complications after open-heart surgery. (2) In patients suffering from respiratory abnormalities, results were good. In those with a derangement of the circulation results were poor. However, it was concluded that therapy in this group is often ju...
متن کاملIntermittent positive-pressure breathing.
Why the continued confusion over the issue of intermittent positive-pressure breathing (IPPB) as related to therapeutic benefits? Welch’s’ communication in response to the article by Loren et a12 comparing simple nebulization and IPPB in asthmatic children fails again to identify specific criteria for therapy with IPPB. Welch and Loren are both correct in identifying the ineffectiveness of ther...
متن کاملeffect of positive end-expiratory pressure on central venous pressure in patients under mechanical ventilation
introduction: finding the probable governing pattern of peep and cvp changes is an area of interest for in-charge physicians and researchers. therefore, the present study was designed with the aim of evaluating the relationship between the mentioned pressures. methods: in this quasi-experimental study, patients under mechanical ventilation were evaluated with the aim of assessing the effect of ...
