What is a central venous pressure?
Central venous pressure (CVP) is a measurement of how much blood they return to the heart through the thoracic vena cava. This provides important information about the heart function that can be used to monitor the patient and adjust the care plan over time. Intensive care units may require continuous measurement of central venous pressure to assess the health of patients and generate the protocol of responses to treatment. The measuring device is available to facilitate secure and efficient data collection and logging. A simple water column can be used to measure pressure changes during the heart cycle. It can feed a device that generates a digital or paper protocol that can be checked for information about the patient's heart function. This recorded data can also be stored in the graph for the future link.
know how much blood is the heart of the heart can help determine how much blood the heart is able to pump into circulation. Changes in central venous pressure can reflect various processes in the body such as dilatation of blood vessels, afterdecrease of blood volume and shifts in heart expenditure. Specific patterns may be indicators of positive or negative reactions to treatment, such as such as heart input support in response to intravenous fluid therapy to increase the total blood volume.
Before procedures, it may be necessary to check the central venous pressure to see if the patient can tolerate the proposed treatment. If it seems unusually low or high, the patient may be stabilized first. Specific devices may have protocols for solving these measurements and responses to CVP changes. These standardizes the treatment provided and increase the chances that patients receive in time and anexional interventions in response to health problems.
The location of the monitoring device requires the patient to hold at rest. Local anesthetic may reduce pain at the point of catheter insertion and also need to sterilize and cover the area to reduce the risk of infectionsce. Once the line is in place, the patient may need an X -ray to confirm that he is in the correct position. Patients must remain relatively inactive to prevent the catheter from being pulled out and the line may need to be rinsed regularly to prevent clots.
