Important Values

Laboratory Test Values, Cardiac Values, Cardiac terminology

Prothrombin time (PT) 11 - 15 sec, If clotting time is increased by 2.5 times or more than normal, therapy is contraindicated.
INR 0.9 - 1.1 (ratio);
WBC Male and Female = 4,300 - 10,800 cells/mm3. If > 5000, light exercise only. If < 5000, with fever, exercise is contraindicated. If <1000, use mark, standard precautions.
RBC Males = 4.6 - 6.4 x 10^6/uL Females = 4.3 - 5.9 x 10^6/uL
ESR Males up to 15mm/hr. Females up to 20 mm/hr. Increased in infection and inflammation
Hematocrit Males 45-52% Females 37-48%
Hemoglobin Males 13-18 g/dL Females 12-16 g/dL
Platelet count 150,000 - 450,000 cells/mm3. If <20,000 = AROM and ADLs only. If 20,000 - 30,000, light exercise only. If 30,000 - 50,000, use moderate exercise.
Stroke Volume 55-100 mL/beat. Amount of blood ejectd with each myocardial contraction.
Cardiac Output CO = SV x HR; Normal is 4-5 L/mon; Amount of blood from L or R ventricle per minute.
Left Ventricular End-Diastolic Pressure (LVEDP) Normal range 5-12 mmHg; Pressure in L ventricle during diastole.
Ejection Fraction EF = SV/LVEDV; Normal average 60-70%; Percentage of blood emptied from ventricle during systole. Clinically useful measure of LV function. The lower the EF, the more impaired the LV.
Rate Pressure Product HR x SBP
PaO2 Adults: 80-100 mmHg Infants: 75-80 mmHg
PaCO2 Adults: 35-45 mmHg Infants: 34-54 mmHg
Tidal Volume Adutls: 500 mL Infants: 20 mL Volume of gas inhaled or exhaled during normal resting breath.
Residual Volume Volume of gas that remains in the lungs after ERV
Inspiratory Capacity IRV + TV; Amount of air that can be inhaled from REEP
Vital Capacity IRV + TV + ERV; Amount of air that is under volitional control; conventionally measured as a forced expiratory vital capacity (FVC)
Functional Residual Capacity ERV + RV; Amount of air that resides in the lungs after a normal resting tidal exhalation.
Total Lung Capacity IRV + TV + ERV + RV; Total amount of air that is contained within the thorax during maximum inspiratory effort.
