pafl 6 phys lab values

normal adult range of hematocrit for male and female

male: 42-52%

female: 37-47%

how does the normal adult range of hematocrit change as one ages?

slightly decrease

resistive/intensive exercise as tolerated for hematocrit

greater than 30%

moderate to light exercises as tolerated for hematocrit

greater than 25%

very light exercise as tolerated for hematocrit

less than 25%

LOW CRITICAL VALUES hematocrit

cardiac failure or death, less than 15-20%

HIGH CRITICAL VALUES hematocrit

spontaneous clotting, greater than 60%

normal adult ranges for hemoglobin

male: 14-18 g/dL

female: 12-16 g/dL

prenant: >11 g/dL

resistive/intensive exercise as tolerated for hemoglobin

greater than 10 g/dL

moderate to light exercises as tolerated for hemoglobin

8-10 g/dL

very light exercise as tolerated for hemoglobin

less than 8 g/dL

LOW CRITICAL VALUES hemoglobin

cardiac failure or death, less than 5-7 g/dL

HIGH CRITICAL VALUES hemoglobin

spontaneous clotting, greater than 20 g/dL

normal adult range for platelets

150,000-400,000 mm3

limit activity range for platelets

less than 20,000, fall risk

low levels: thrombocytopenia

less than 150,000, risk of spontaneous hemorrhage

high levels: thrombocytosis

greater than 450,00, risk of venous thromboembolism

normal adult range for prothrombin time ( determines coagulability)

11-12.5 sec

limit activity for prothrombin time

possible critical value is more than 20 seconds, activity may be contraindicated

normal adult range for INR

0.8-1.1 ratio= normal target therapeutic ranges vary by goal of treatment

limit activity for INR

if greater than 2.0-3.0, consult with the MD

what activity can you do with a platelet count less than 20,000?

active ROM, ambulation, ADLs

physician approval is recommended

what activity can you do with a platelet count between 20,000 and 50,000?

vigorous activity is contraindicated, IF there are no signs of bleeding, individual can do active ROM, ambulation, mild intensity cardiovascular exercise, light strength training, no prolonged stretching

what activity can you do with a platelet count between 50,000 and 150,000?

light restrictive exercise as tolerated, aerobic activities (swimming, cycling flat surfaces, avoid high intensity)

when to seek medical attention?

bleeding!!!

how does HR range per 1 MET?

10 bpm

how does systole change per 1 MET?

7-10

how does diastole change per 1 MET?

it shouldnt change
