|---|---|---|---|---|---|
| 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.
🗑

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.
🗑
