Shunt/deadspace

Front 1

A passage between two natural body channels, such as blood vessels, especially one created surgically to divert or permit flow from one pathway or region to another; a bypass.

GENERAL MEDICAL DEFINITION OF SHUNT

Front 2

WHAT ARE THE 3 COMMON CAUSES OF A CAPILLARY SHUNT

Back 2

1 ATELECTASIS (ALVEOLAR COLLAPSE)
2 ALVEOLAR FLUID ACCUMULATION
3 ALVEOLAR CONSOLIDATION

Front 3

A PT WITH AN INCREASED VQ RATIO IS SAID TO HAVE? WHAT ARE SOME DISEASES THAT MAY HAVE THIS

Back 3

DEAD SPACE VENTILATION
BECAUSE THE EXCESS WILL BE WASTED

Front 4

SHUNT IN RESPIRATORY REFURS TO? COMMON DISEASES?

Back 4

DECREASED VQ RATIO (VENTILATION TO PURFUSION)
ASTHMA, PNEUMONIA
DECREASE VENTILATION IN BLOOD FLOW

Front 5

NORMAL VQ RATIO AND WHAT IT REFURS TO

Back 5

4:5 OR.8
VENTILATION TO PREFUSION
REFURS TO THE ALVEOLAR VENTILATION 4LPM TO PULMONARY CAPILLARY BLOOD FLOW 5LPM

Front 6

PHYSIOLOGICAL DEAD SPACE IS THE COMBINATION OF WHAT TWO TYPES OF DEAD SPACE'S

Back 6

ANATOMICAL AND ALVEOLAR

Front 7

DEAD SPACE IN SHORT MEANS

Back 7

WASTED VENTILATION
DOESN'T PARTICIPATE IN GAS EXCHANGE

Front 8

EXPLAIN SHUNT AS FAR AS RESPIRATORY WISE, IN THE TWO BROAD BRANCHES

Back 8

BRANCH 1 RIGHT TO LEFT
A BYPASS BETWEEN THE VENOUS (RIGHT) AND ARTERIAL (LEFT) SIDES OF THE CIRCULATION. POORLY OXYGENATED VENOUS BLOOD INTO THE ARTERIAL BLOOD CAUSING A DECREASE IN OXYGENATION.
BRANCH 2 LEFT TO RIGHT
OXYGEN CONTENT OF THE ARTERIAL BLOOD IS NOT AFFECTED. HOWEVER CARDIAC WORKLOAD IS SIGNIFICANTLY INCREASED.

Front 9

THE TWO RIGHT TO LEFT ANATOMICAL SHUNTS WHICH EXIST IN THE NORMAL HUMAN BEING
AND HOW DO THESE SHUNTS WORK

Back 9

1THE BRONCHIAL VENOUS DRAINAGE
2THE THEBESAIN VENOUS DRAINAGE

BY DIVERTING POORLY OXYGENATED VENOUS BLOOD INTO THE ARTERIAL CIRCULATION CAUSING LOWER OXYGEN CONTENT IN THE ARTERIAL BLOOD

Front 10

EXPLAIN SHUNT AS FAR AS RESPIRATORY WISE IN THE TWO BROAD BRANCHES

Back 10

RIGHT TO LEFT BRANCH 1
A BYPASS BETWEEN THE VENOUS (RIGHT) AND ARTERIAL (LEFT) SIDES OF THE CIRCULATION. POORLY OXYGENATED VENOUS BLOOD INTO THE ARTERIAL BLOOD CAUSING A DECREASE IN TOTAL OXYGENATION.
LEFT TO RIGHT BRANCH 2
OXYGEN CONTENT OF THE ARTERIAL BLOOD IS NOT AFFECTED. HOWEVER CARDIAC WORKLOAD IS SIGNIGICANTLY INCREASED

Front 11

SHUNT EXPLAINED IN ITS SIMPLEST FORM

Back 11

A PATH
SURGICALLY A PHYSICIAN WILL REROUTE FOR A NEW PATH FOR FLUID ETC

Front 12

DEADSPACE: RESPIRED GAS VOLUME THAT DOES NOT PARTICIPATE IN GAS EXCHANGE (THE PORTION THAT IS RE-ENTERED NOT FRESH) CAN BE EITHER ANATOMIC, ALVEOLAR, OR MECHANICAL. EXPLAIN ALVEOLAR

Back 12

ANATOMICAL-NORMAL FOR EVERYONE
FOR EVERY POUND A PT WEIGHS, IS HOW MANY ML OF OXYGEN THAT DOESN'T PARTICIPATE IN GAS EXCHANGE AS IT IS REBREATHED
EX: 150POUND PT 150ML DEAD SPACE

Front 13

EXPLAIN THE ALVEOLAR DEADSPACE

Back 13

THE ALVEOLI ARE NOT PREFUSING WITH VENOUS BLOOD. PULMONARY EMBOLISM WILL CAUSE THIS BY BLOCKING A PORTION OF THE PULMONARY CIRCULAION

Front 14

WHAT TYPES OF SHUNTING IS REFRACTORY TO OXYGEN THERAPY AND WHY

Back 14

CAPILLARY SHUNT
BECAUSE THE ALVEOLI ARE UNABLE TO PROVIDE ANY 02/CO2 EXCHANGE FUNTION. IN OTHER WORDS NO BENIFIT

Front 15

THE SUM OF WHICH TWO SHUNTS IS CONSIDERED A TRUE OR ABSOLUTE SHUNT

Back 15

ANATOMIC SHUNT

2-5%

Front 16

ALVEOLAR- A SECOND KIND OF DEAD SPACE MEANS

Back 16

THAT THE ALVEOLI ARE NOT PERFUSING WITH VENOUS BLOOD. A PULMONARY EMBOLIS WILL CAUSE THIS BY BLOCKING A PORTION OF THE PULMONARY CIRUCULATION
