allows for calculation ofhemodynamic indices and

limited data storage


3/22

Measure hemodynamic parameters

Closely examine cardiovascular

function

Evaluate cardiac pump output and

volume statusRecognize patterns ( arrhythmia

analysis) and extract features

response to stimuli

Continuously assess respiratory

gases (capnography)

Continuously evaluate blood gasesand electrolytes


5/22

Estimulate cellular oxygenation

Continuously evaluate glucose levels

Store waveformsAutomatically transmit selected data

to a computerized patient database

is the assessment of the

patients circulatory status.

is an essential component of

quality patient care


7/22

to alert the health care team to impending

cardiovascular crisis before organ injury

ensues; it is routinely used in this manner in

the operating room during high-risk surgery.

to obtain information specific to the disease

processes, which may facilitate diagnosis andtreatment and allow one to monitor the

response to therapy.

10/22

- have traditionally involved use of thepulmonary artery catheter (PAC),

which was originally designed formeasurement of pulmonary arteryand wedge pressures

- invasive catheters are typically usedto measure and monitor variouspressures and cardiac output

emboli


13/22

Includes...

pressure measurement using

oscillometric techniques

generation measurement using

pulse oximetry technology

measurement of cardiac output viaDoppler


14/22

Mean Arterial Pressure (MAP):

70-90mmHg

Central Venous Pressure (CVP):2-8mm Hg

Pulmonary Artery Systolic (PAS):

20-30mmHg

Pulmonary Artery Diastolic Pressure (PAD):6-12mm Hg


15/22

Pulmonary Artery Mean Pressure (PCWP,

Wedge):

8-12mm Hg

Cardiac Output (CO):

4-8 L/min Cardiac Index (CI):

2.5-4 L/min.

Stroke Volume (SV):

60-130 ml


16/22

Stroke Volume Index (SVI):

40-50 ml/m2

Systemic Vascular Resistance (SVR):

800-1200 dynes

Systemic Vascular Resistance Index

(SVRI):

2000-2400 dynes Pulmonary Vascular Resistance (PVR):

150-300 dynes


17/22

Cardiac output

- is the heart rate times the stroke

volume and is the amount of blood

pumped by the ventricles each minute.


18/22

Heart rate is the number of heartbeats perunit of time - typically expressed as beats per

minute (bpm) - which can vary as the body's

need for oxygen changes, such as during

exercise or sleep.

Stroke volume is the amount of blood ejected

with each cardiac contraction/heart beat


19/22

Cardiac index

- is the cardiac output adjusted tobody size and is a better parameter

to use than the cardiac output


20/22

SVR (systemic vascular resistance)

- the vascular resistance offered by the

peripheral circulation

Stroke volume variability


21/22


22/22

Clinicians must keep in mind that the

monitor and its information do not

replace clinical judgement or necessarily

imply quality patient care.
