HEMODYNAMIC MONITORING

OBJECTIVE

04/18/232

1. Describe the three attributes of circulating blood and their relationships.

2. Identify types of clients in which hemodynamic monitoring would be

indicated.

3. Describe the types of catheters used for hemodynamic monitoring.

4. Discuss the normal and abnormal values obtained through hemodynamic monitoring as they relate to specific client

situations.

5. List the potential complications in use of hemodynamic monitoring

devices.

6. Explain nursing responsibilities when caring for patient on hemodynamic monitoring.

7. Describe the procedure for setting up a hemodynamic circuit.

HEMODYNAMIC MONITORING

04/18/233

DEFINITION:Using invasive technology to provide quantitative information about vascular

capacity, blood volume; pump effectiveness, and tissue perfusion

NURSING RESPONSIBILITIES 1. Pre-Insertion:  a. Patient & significant others

teaching. b. Thorough baseline assessment

c. Equipment set-upd. Positioning of the cliente. Equipment check (calibration, zero

etc.)

NURSING RESPONSIBILITIES 3. Post-Insertion  a. Chest X-ray for placemenb. Sterile OCCLUSIVE dressing,

stabilization of the catheterc. Patient comfortd. Assess and document pressures/datae. Catheter maintenancef. Monitor patients response

HEMODYNAMIC MONITORING

04/18/2314

NURSING RESPONSIBILITIES Maintenance of the System: a. Label and date lines, change tubing as per unit policy b. Maintain & change dressing c. Alert for waveform and pressure changes d. Maintain pressure/pressure bag e. Keep balloon deflated between PCWP readings

f. Collaboration and communication with physician

g. Remember to care for the patient as well as your equipment

POTENTIAL COMPLICATIONS  1. Dysrhythmias

2. Infection 3. Pneumothorax4. Pulmonary infarction 5. Balloon rupture and air embolism6. Pulmonary artery rupture

7. Endocarditis  

HEMODYNAMIC MONITORING

04/18/2316

ARTERIAL PRESSURE MONITORING: 1. Indications 2. Assessment data:   * MAP = (diastolic x 2)+(systolic)

3

* MAP - ICP = CPP 

HEMODYNAMIC MONITORING

04/18/2317

ARTERIAL PRESSURE MONITORING:3. Arterial Waveform  a. Aortic valve opens and blood is ejected

from LV and is recorded as an increase in pressure

b. Highest point represents systole

c. Lowest point is diastolic pressure 

HEMODYNAMIC MONITORING

ARTERIAL PRESSURE MONITORING:4. Nursing Responsibilities5. Potential Complications: a. Thrombosis at catheter tip

b. Infection c. Bleeding d. Loss of flow distal to extremity
