Hemodynamic monitoring- Hemodynamic monitoring refers to the measurement of pressure, flow and oxygenation within the cardiovascular system. Hemodynamic monitoring is amandatory process in all the critical care units to assess the patients progress. This presentation is aimed to create an insight on Hemodynamic monitoring.

the measurement of pressure, flow
and oxygenation within the
cardiovascular system.

10. DEFINITION
BLOOD PRESSURE IS THE MEASSURE
OF THE FORCE EXERTED ON THE ARTERIAL
WALLS BY THE BLOOD CONTAINED WITHIN THE
ARTERIAL SYSTEM.
Mrs. Soumya Subramani, M.Sc. (N) 10
14. OSCILLOMETRIC METHOD
WHEN AN INFLATED CUFF IS PLACED OVER
AN ARTERY, THE PULASTILE PRESSURE
CHANGES IN THE ARTERY WILL BE
TRANSMITTED TO THE INFLATED CUFF
PRODUCING SIMILAR CHANGES IN CUFF
PRESSURE.
Mrs. Soumya Subramani, M.Sc. (N) 14
15. PROPER FIT OF A BLOOD PRESSURE CUFF
Width of bladder = 2/3 of upper arm
Length of bladder encircles 80% arm
Lower edge of cuff approximately 2.5
cm above the antecubital space
Mrs. Soumya Subramani, M.Sc. (N) 15
16. Why A Properly Fitting Cuff?
Too small causes false-high reading
Too LARGE causes false-low reading
Mrs. Soumya Subramani, M.Sc. (N) 16
17. BASIC EQUIPMENTS IN THE PRESSURE MONITORING SYSTEM
TRANSDUCER
AN AMPLIFIER WITH A RECORDING SYSTEM
INVASIVE CATHETER, TUBING & FLUSH SYSTEM
STOP COCKS
Mrs. Soumya Subramani, M.Sc. (N) 17
19. PRINCIPLES OF INVASIVE
PRESSURE MONITORING
TO ACCURATELY MEASURE PRESSURE, EQUIPMENTS
MUST BE REFERENCED AND ZERO BALANCED TO THE
ENVIRONMENT AND DYNAMIC RESPONSE
CHARACTERISTICS OPTIMISED.
Mrs. Soumya Subramani, M.Sc. (N) 19
23. PRINCIPLES OF INVASIVE PRESSURE MONITORING
ZEROING CONFIRMS THAT WHEN PRESSURE WITHIN
THE SYSTEM IS ZERO,THE MONITOR READS ZERO.
OPTIMISING DYNAMIC RESPONSE CHARACTERISTICS
INVOLVES CHECKING THAT THE EQUIPMENT
REPRODUCCES, WITHOUT DISTORTION,A SIGNAL THAT
CHANGES RAPIDLY.
Mrs. Soumya Subramani, M.Sc. (N) 23
25. INDICATIONS FOR CENTRAL
VENOUS CANNULATIONS
ADMINISTATION OF FLUID AND ELECTROLYTES
DRUG THERAPY
VENOUS ACCESS FOR MONITORING CVP
PARENTERAL NUTRITION
INSERTION OF TRANS VENOUS PACEMAKER
ADMINISTRATION OF BLOOD &BLOOD PRODUCTS
LACK OF ACCESSIBLE PERIPHERAL LINE
Mrs. Soumya Subramani, M.Sc. (N) 25
26. TYPES OF CENTRAL VENOUS
CATHETERS
SINGLE LUMEN CATHETER
MULTI LUMEN CATHETERS
Mrs. Soumya Subramani, M.Sc. (N) 26
27. Central venous pressure interpretation
NORMAL CVP : 2-6mmHg OR 2-8cmH2O
HIGH CVP>7mmHg
- NORMOVOLEMIC
RIGHT SIDED HEART FAILURE
CHRONIC BIVENTRICULAR FAILURE
PERICARDIAL DISEASES
PNEUMOTHORAX
PULMONARY STENOSIS
LOW CVP-HYPOVOLEMIC SHOCK
Mrs. Soumya Subramani, M.Sc. (N) 27
28. SOURCES OF VARIABILITY
BODY POSITION
PRESSURE MONITORING
UNIT OF MEASUREMENT
PRESSURE MEASURE IN cmH2O CAN
BE DEVIDED BY 1.36 TO BE EXPRESSED IN mmHg.
Mrs. Soumya Subramani, M.Sc. (N) 28
