  3. Centimeter Scale The Centimeter Scale located at the top of Side A is used for a wide variety of medical applications, including measurement of skin lesions.

  4. Body Temperature Scale In this example, the patient’sbody temperature of 102.9°F (39.4°C)is a low grade fever by rectal thermo-meterbut a mid grade fever by ear or oral thermo-meter. The Body Temperature scale displays a patient’s hypothermia or fever range, and interconverts Fahrenheit to Centigrade Body Temperature ranges are displayed for three types of thermometers – Eardrum scan, Oral, and Rectal.

  5. Annual Calendar ScaleMonth - to - Month Transitions A small diagonal line marker is used to easily and rapidly identify the first day of each month on the Calendar Scale in order to facilitate easy month-to-month transitions for clinical scheduling.

  6. Christmas – red dot New Years Day – black dot Fixed Holiday Markers Valentines Day – red dot Halloween – orange dot Fixed holidays are marked by color dots on the Calendar Scale to assist clinical scheduling near certain holidays. St Patrick's Day – green dot Forth of July – blue dot

  7. Average Cycle Length Scale In this example: LMP on January 7 for 36 day cycles LMP on January 15 for 28 day cycles The Average Cycle Length scale automatically adjusts the position of the Last Menstrual Period (LMP) marker to compensate for variations in Menstrual Cycles LMP on January 21 for 22 day cycles

  8. The Average Cycle Length scale automatically compensates for cycle variations to greatly improve accuracy in Gestational Age and Due Date Average Cycle Length Scale Example: LMP is on January 25 for average cycle length of 28 days Due Date is on November 3rd

  9. 38 Average Cycle Length Scale Due Date is on November 13th if average cycle length is 38 days Example: For LMP on January 26th Due Date is on October 28th if average cycle length is 22 days 22

  10. Sperm Exposure Scale Example: Intercourse between April 17 and April 25 may result in pregnancy. Rarely, sperm may remain viable for up to 7 days before ovulation. Most conceptions occur with sperm 0 to 3 days old. Eggs are fertilizable for 28 hours after ovulation, so intercourse up to 24 hours after ovulation may result in conception.

  11. Missed next Menstrual Period would have been on June 13 Embryo Implantation is on June 6 Ovulation is on May 30 Early Pregnancy Landmarks Pregnancy test would be positive between June 10 and June 19 Example: For LMP on May 16

  12.

  13. Calculate Infant Age by aligning the Birthday Marker (also the LMP 28 day marker) with baby’s date of birth, then align the cursor marker with the current date. Read the infant's age in days at the cursor marker position on the Light Blue Days Scale. Infant Age in Days Birthday Example 1: For Birthday on October 5, infant age on December 17 is 73 days Example 2: For Birthday on October 5, infant age on June 26 is 263 days Birthday

  14. Gestational AgeCrown-Rump Length and Fetal Weight This is Day 59 of gestation, and Fetal Heart Motion should be visible on ultrasound Displays the average Crown-Rump Length (in mm)and Fetal Weight (in gms)for gestational age range 4 weeks 2 days to 12 weeks 4 days, for each gestational age and corresponding calendar date. Example: On March 20 the gestational age is 8 weeks 3 days The Crown Rump Length (CRL) should be 18 mm Fetal weight is approximately 1.5 gms

  15. Gestational Age Biparietal Diameter and Fetal Weight This is Day 226 of gestation, and CBC should be ordered. Displays the average Biparietal Diameter(in mm)and Fetal Weight (in gms)for gestational age rangefrom 12 weeks 4 days to 42 weeks for each gestational age and corresponding calendar date. Example: On September 5 the gestational age is 32 weeks 2 days Biparietal Diameter (BPD) should be 8.3 cm Fetal Weight is approximately 1800 gms

  16. Calculates past and future expected calendar dates of Menstrual Periods for patients with regular 28 day cycles. Align the LMP 28 day marker with the current date, then align the cursor marker with a red dot on the Light Blue Days scale and read the calendar date indicated by the cursor. Use the 1st, 2nd, 3rd, 4th,etcred dot to predict Menstrual Dates for 1, 2, 3, 4, etc cycles in the future. Menstrual Period Predictor Expected MP in 2 cycles Example: For LMP on June 1, in 2 cycles the expected MP will start July 27. 1st dot 2nd dot

  17. To calculate past calendar dates of Menstrual Periods, align the cursor marker on the appropriate (1st, 2nd. 3rd ,etc) red dot on the date of the current or last Menstrual Period, then read the date of the desired past Menstrual Period at the LMP 28 day marker. Menstrual Period Predictor MP 2 cycles ago Current MP Example: For current Menstrual Period on July 27, the Menstrual Period two cycles ago started on June 1. 1st dot 2nd dot

  18. Example: Patient Weight is 190 lbs Patient Height is 5’ 9” Align 5’ 9” with 190 lbs on the Height & Weight scales The BMI is 28 kg/m2 in the Overweight range Body Mass Index Calculator Calculates the Patient’s Body Mass Index (BMI) from Height and Weight, and displays the result using color coded body type ranges. Use the Pink field on Side A

  19. Calculates patient's rate of respiration from total number of inspirations during a time period ranging from 10 seconds to 45 seconds. Respiration Rate Calculator Example: The patient has 6 inspirations during a 20 second observation period. Align the 20 second marker with the Respiration 6 marker The Respiration Rate is 18 per minute (rpm) In This Case: For a 4-year-old child, this respiration rate is in the Hypoventilation range For a 16-year-old patient, this respiration rate is in the Normal range

  20. Calculates patient's heart rate from total number of pulses during a time period ranging from 10 seconds to 45 seconds. The most common time period used to measure pulse rate is 15 seconds, identified by a bold marker on the time scale. Pulse Rate Calculator In This Case: For a 4-year-old child, this heart rate is in the Normal range For an Adult, this heart rate is in the Tachycardia range Example: The patient has 28 pulses during a 15 second observation period. Align the 15 second marker with the Pulse Count 28 marker The pulse rate (heart rate) is 110 per minute (bpm)

  21. Marketing Space On this demonstration model, there are two blank regions on Side A and one large region on Side B available for marketing information.

  22. SIDE B * ECG Heart Rate calculator– two speeds * Conversion Scale – centimeters to inches * Waist to Hip Ratio calculator * Waist to Hip Ratio mortality risk calculator – male and female * Waist to Hip Ratio population percentile – male and female * Conversion Scale – pounds to kilograms * Drug Dose calculator by Body Weight * Drug Dose Syringe Volume calculator by Body Weight Large surface area for marketing information

  23. Align the first QRS complex with the reference arrow on the scale. Read heart rate (in bpm) at the position of the First or Second QRS complex, depending upon ECG paper speed. ECG Pulse Rate Calculator For ECG paper speed of 25 mm/sec, read heart rate at the Second QRS complex. For ECG paper speed of 50 mm/sec, read heart rate at the First QRS complex. This scale calculates a patient's heart rate by measuring the distance between one or two QRS complexes on a standard ECG strip.

  24. Align the first QRS complex with the reference arrow on the scale. ECG Pulse Rate Calculator For Low Heart Rates (Bradycardia) This scale calculates a patient's heart rate by measuring the distance between one or two QRS complexes on a standard ECG strip. For Bradycardia, use the Dark Green scale at paper speed of 25 mm/sec. Read heart rate at the First QRS complex.

  25. 0 1 2 ECG Pulse Rate Calculator 0 1 xx xx For standard paper speed of 25 mm/sec, this patient has a heart rate of 35 beats/min as indicated at the First QRS complex on the Dark Green scale. for Normal Range or Tachycardia xx For standard paper speed of 25 mm/sec, this patient has a heart rate of 112 beats/min as indicated at the Second QRS complex on the Light Green scale. for Bradycardia

  26. Interconversion of Inches to Centimeters is done using the Waist-to-Hip Ratio scale in the pink field on side B. Inch to Centimeter Converter 47 inches equals 120 cm Lay a straight edge or paper edge, aligned with the center of the calculator, across the scales to inter-convert centimeter measurements to inch measurements.

  27. Calculates the Waist to Hip Ratio (WHR) from the patient's Waist Circumference and Hip Circumference (in inches or centimeters) Waist to Hip Ratio Calculator Example: For a patient with Waist Circumference of 45 in and Head Circum-ference of 50 in: Align the 45 marker on the Waist inches scale with the 50 marker on the Hip inches scale. Read the Waist to Hip Ratio (0.9) in the WHR Window.

  28. The Waist-to-Hip Ratio is useful for determining the a patient's general risk of Mortality. This feature also calculates the Population Percentile for the patient's waist to hip ratio. Waist to Hip Ratio Mortality Risk and Population Percentile by Sex Example: For a Waist-to-Hip Ratio of 0.9 The Relative Risk of Mortality for a woman is 1.4 The Relative Risk of Mortality for a man it is 0.9 Women with a WHR of 0.9 are in the 85th percentile. Men with a WHR of 0.9 are in the 55th percentile 85th 1.4 55th 0.9

  29. This feature interconverts body weight from Pounds to Kilograms, or vice versa. Align thepatient’s body weight at the Weight in Pounds marker,then read the patient's metric body weight at the Weight in Kilograms marker. Pound to Kilogram Converter In this example, a 154 pound patient weighs 70 kilograms. Example: 70 kg - - - - - - - - - - - equals - - - - - - - - - - - - 154 pounds

  30. Rapid determination of a drug dose is accomplished by aligning the patient's Body Weight (in pounds or kilograms) along the outer yellow scale, then reading the Drug Dose (in milligrams) where the appropriate reference line intersects the Dose Scale. Drug Dose Calculator by Body Weight Patient weighs 146 lbs Example: A patient who weighs 146 pounds needs a medication administered at 0.75 mg/kg. The calculated dose is 45 mg.

  31. Drug Dose Calculator by Syringe Volume Example: A patient who weighs 280 pounds needs a Pharmatropin injection. The calculated volume of Pharmatropin is 0.60 ml. Rapid determination of the Syringe Volume of an injectable drug is accomplished by aligning thepatient's Body Weight (in pounds or kilograms) along the outer yellow scale, then reading the Syringe Volume (in milliliters) at the level of the Red Field inside the syringe diagram.
