ASSESS THIS BLOOD GAS:
PH 7.31 PCO2 52 PO2 58 HCO3 25 (TWO WAYS OF IDENTIFYING) |
NON COMPENSATED RESPIRATORY ACIDOSIS WITH MILD HYPOXEMIA
OR ACUTE VENTILATORY FAILURE |
|
|
ACUTE ALVEOLAR HYPERVENTILATION (ALSO CALLED RESPIRATORY ALKALOSIS IS WHEN WHICH VALUE OF THE BLOOD GAS HAS DECREASED AND WHY?
|
PACO2, HYPOXEMIA
HYPOXIA INCREASES RR CAUSING A BLOW OFF OF CO2 (TRYING TO COMPENSATE) |
|
|
WHAT ARE THE FOUR POSSIBLE WAYS IN WHICH TO RECEIVE A BLOOD GAS IN ORDER OF SAFETY AND WHY?
|
ARTERIAL LINE-IF A PT HAS THIS, SAFER ALSO NO RESTICKS
RADIAL-ALLENS TEST-COLLATERAL BLOOD FLOW BRACHEAL-SAFER THAN FEMORAL FEMORAL-LAST RESORT |
|
|
WHAT IS THE MODIFIED ALLENS TEST AND WHY IS IT IMPORTANT PRIOR TO OBTAINING AN ABG
|
A POSITIVE ALLENS TEST INSURES COLLATERAL BLOOD FLOW FOR SAFETY INCASE ARTERY IS DAMAGED OR SLICED.
|
|
|
EXPLAIN THE MODIFIED ALLENS TEST AND DESIRED OUTCOME
|
HOLD ARM IN THE AIR WHILE PRESSURE IS APPLIED TO THE RADIAL AND ULNER ARTERY-HOLD ARM BACK LEVEL AND RELEASE RADIAL ARTERY. BLANCHING SHOULD ACCURE IN TWO SEC AT MOST
|
|
|
WHEN YOU BLOW OFF TOO MUCH PCO2 YOU ARE_____, YOUR _______ TRYS TO CORRECT THE PROBLEM BY RETAINING________ IN THE BLOOD
|
HYPERVENTILATING
KIDNEYS HCO3, BASE OR BICARB |
|
|
ASSESS THE FOLLOWING BLOOD GAS
PH 7.32 PCO2 50 HCO3 29 PAO2 84 |
PARTIALLY COMPENSATED RESPIRATORY ACIDOSIS
BOTH PACO2 AND HCO3 ARE HIGH PH IS NOT IN NORMAL RANGE YET PARTIALLY COMPENSATED |
|
|
AN UNUSUAL BLOOD GAS REVEALS A PACO2 THAT IS VERY HIGH AND THE PH IS NOT AS LOW AS YOU WOULD EXPECT CONSIDERING THE PACO2. THIS PT IS SAID TO HAVE?
PH 7.21 PACO2 110 HCO3 43 PAO2 34 |
ACUTE VENTILATORY FAILURE SUPERIMPOSED ON CHRONIC VENTILATORY FAILURE
PH WOULD NORMALLY BE AT 7.05 WITH A PACO2 OF 110 |
|
|
ASESS THIS BLOOD GAS
PH 7.52 PACO2 24 PAO2 61 HCO3 22 TWO WAYS TO CALL THIS |
UNCOMPENSATED (ACUTE) RESPIRATORY ALKALOSIS WITH HYPOXEMIA
OR ACUTE ALVEOLAR HYPERVENTILATION WITH HYPOXEMIA |
|
|
WHEN IS A BLOOD GAS OR OXYGEN SATURATION USELSS AND WHY
|
POST FIRE OR CARBON MONOXIDE POISIONING. THIS WILL GIVE A FALSE READING AS THE CO WILL ATTATCH TO THE HEMOGLOBIN.
|
|
|
T OR F
NEVER ATTEMPT AN ABG ON A PT WITH AN INDWELLING DIALYSIS SHUNT RADIAL OR BRACHIAL |
T
USE DIFFERENT SITE |
|
|
WHEN RENAL COMPENSATION, THAT IS WHEN HCO3 HAS INCREASED TO THE POINT THAT THE PH HAS RETURNED TO NORMAL, THE TERM
____________ IS USED |
CHRONIC VENTILATORY FAILURE
PH DECREASED 7.38 PACO2 INCREASED 66 HCO3 INCREASED 35 PAO2 DECREASED 63 |
|
|
WHAT MUST AN RT ALWAYS BE MINDFUL OF PRIOR TO DOING A BLOOD GAS
|
1. ANTICOAGULATION MEDICATION (CLOTT BUSTERS) HEPARIN OR COUMADIN, STREPTOKINASE
2. A PT WHICH HAS AN INDWELLING DIALYSIS SHUNT ON THE ARM YOU ARE CONSIDERING |
|
|
THE TERM USED TO MEAN: A CONDITION IN WHICH THE LUNGS ARE UNABLE TO MEET THE METABOLIC DEMANDS OF THE BODY IN TERMS OF CO2 HOMEOSTASIS
|
VENTILATORY FAILURE
|
|
|
THE DIFFERENCE BETWEEN VENTILATORY FAILURE AND RESPIRATORY FAILURE
|
VENTILATORY FAILURE: CO2 PROBLEM
RESPIRATORY FAILURE: PAO2 OXYGEN PROBLEM |
|
|
WHEN THE PH IS NORMAL AND THE PACO2 IS HIGH A PT IS SAID TO BE IN
|
CHRONIC VENTILATORY FAILURE
|
|
|
HOW CAN AN RT CETCH A PT THAT HAS ACUTE ALVEOLAR HYPERVENTILATION SUPERIMPOSED ON CHRONIC VENTILATORY FAILURE AND REALIZE THAT THE BLOOD GAS IS NOT WHAT IT APPEARS WHICH IS PARTIALLY COMPENSATED METABOLIC ALKALOSIS
|
BY THE PAO2 BEING LOW (HYPOXIA)
WHEN A PT HAS ALKALOSIS THE PAO2 IS NORMALLY IN A GOOD RANGE AS THEY ARE HYPERVENTILATING PH 7.53 PACO2 51 HCO3 37 PAO2 46 <---- DING DING DING |
|
|
HOLD PRESSURE ON A BLOOD GAS SITE FOR
|
2-5 MIN
MORE IF A PT IS TAKING BLOOD THINNERS |
|
|
WHAT RANGES ARE NORMAL FOR A BLOOD GAS
|
PH 7.35-7.45
PACO2 35-45 PAO2 80-100 HCO3 22-26 |
|
|
WHAT TEST IS USED IF A PT IS SUSPECTED OF BEING IN A FIRE
HOW SHOULD THE PT BE TX |
CO-OXIMETER
TX 100% NON REBREATHER, HYPERBARIC CHAMBER |
|
|
POST OBTAINING A BLOOD GAS SAMPLE, ROOM AIR SAMPLE WILL NEED TO BE RAN WITHIN?
ON ICE |
ROOM AIR 10 MIN
ICE 60 MIN |
|
|
