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
