Rationale: The preferred solution for the flush bag is a 0.9% sodium chloride solution. Consider using an arterial blood conservation system with the arterial pressure line. Follow the organization’s practice regarding the use of a 0.9% sodium chloride solution or a heparinized 0.9% sodium chloride solution in the flush solution for the pressure monitoring system.Explain the procedure and ensure that the patient agrees to treatment.ĭisposable Pressure Transducer System Setup.Don appropriate PPE based on the patient’s need for isolation precautions or risk of exposure to bodily fluids. Place the patient in the supine position with the head of the bed flat or elevated up to 60 degrees.Assess the patient for conditions that may warrant the use of a hemodynamic monitoring system, including hypotension, hypertension, cardiac failure, shock, hemorrhage, respiratory failure, fluid imbalances, and sepsis.Verify the correct patient using two identifiers.Don appropriate PPE based on the patient’s need for isolation precautions or the risk of exposure to bodily fluids. Perform hand hygiene before patient contact.Encourage questions and answer them as they arise.Provide the patient and family with an explanation of the equipment and the procedure.Provide developmentally and culturally appropriate education based on the desire for knowledge, readiness to learn, and overall neurologic and psychosocial state.6 Forced connections or workarounds could indicate that the connection should not be made. 3 Connections should not be forced, and equipment should only be used for its intended purpose. Labeling the tubing reduces the chance of misconnection, especially in circumstances where multiple IV lines or devices are in use. The external reference point of the atria is the phlebostatic axis. All hemodynamic values (PA, RA, and arterial) are referenced to the level of the atria. With this system, arterial pressure, PA pressure, and RA pressure can be obtained. A triple-pressure transducer system is commonly used to measure pressure from the arterial and PA catheters ( Figure 3). A double-pressure transducer system is used to measure pressure from two catheters (e.g., arterial and central venous) or two ports (e.g., PA and RA) from a single catheter (e.g., PA catheter) ( Figure 2). ![]() Invasive measurement of intracardiac (right atrial and pulmonary artery ) pressure requires insertion of a catheter into the PA.Ī single-pressure transducer system is used to measure pressure from a single catheter (e.g., arterial or central venous) ( Figure 1). Invasive measurement of intravascular (arterial) pressure requires insertion of a catheter into an artery. ![]() Intravascular and intracardiac pressure transducers detect the pressure generated in various areas of the cardiovascular system and convert that pressure wave into an electrical signal, which is transmitted to the monitoring equipment for representation as a waveform on the oscilloscope. ![]() The transducer detects a biophysical event and converts it to an electronic signal.įluid-filled pressure monitoring systems used for bedside hemodynamic pressure monitoring are based on the principle that a change in pressure at any point in an unobstructed system results in similar pressure changes at all other points in the system. Transducer systems provide a catheter-to-monitor interface so intravascular and intracardiac pressure can be measured. ![]() Route tubes and catheters having different purposes in different, standardized directions (e.g., IV lines routed toward the head enteric lines toward the feet). The transducer system must be leveled and zeroed to provide accurate hemodynamic values. Transducer System Setup and Zeroing - CE ALERTĭon appropriate personal protective equipment (PPE) based on the patient’s signs and symptoms and indications for isolation precautions.
