Laboratory Tests and values Flashcards
what is the primary measure used for MI
Cardiac troponin (I or T) it most accompany one of the following symptoms
1) symptoms of ischemia
2) new or persumed ST changes on the ECG
3) development of pathological Q waves on ECG
4) new loss of viable myocardium and/ or new wall motion or abnormality
5) evidence of intracoronary thrombus via catherization or autopsy.
Elevation of CK and CPK (serum creatine kinase or creatine phosphokinase) with CKMB but peaks around 12-24 hours and maybe to late to catch and person may already have had a heart attack by then.
Arterial Blood Gases whats approiate values for
SPO2, PaO2, PaCO2, blood ph and what are the indications if they are high or low
SPO2 or SaO2 should be 95 -100% below 88-90 percent Pt. will more than likely need supplemental oxygen
PaO2- 90-100 mmHG he PaO2, is the partial pressure of O2 in arterial blood– typically measured via ABG.
SaO2 measures as a percentage the amount of hemoglobin molecules which are oxygenated (oxyhemoglobin) in arterial blood
PaCO2 - 35 - 45 mmHG - if there is to much CO2 then the person more likely has some form of COPD because they are not getting the CO2 out of the body via the lungs. Then a decrease of PaCO2 would indicative of that a person is getting rid of to much CO2 and is probably hyperventilating, pregnancy, severe anxiety, or pulmonary embolism
blood PH - should be between 7.35 - 7.45. If below 7.35 means its acidic indicating that they can respiratory acidosis (hypoventilation, COPD, respiratory depressants, mysathenia gravis indicating a problem with the diaphargm)
Platelet count??? what is the normal range and what is its signficance
Normal value (150,000-450,000) increased is equal to chronic leukemia, A decrease is indicative of thrombocytopenia, acute leukemia, aplastic anemia, cancer chemotherapy Physical therapy considerations!! increased risk of bleeding with low levels so monitor for hematuria, petechiae, and other signs of active bleeding.
