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.
Body Temperature Scale The Body Temperature scale displays a patients hypothermia or fever range, and interconverts Fahrenheit to Centigrade Body Temperature ranges are displayed for three types of thermometers – Eardrum scan, Oral, and Rectal. In this example, the patients body temperature of 102.9°F (39.4°C) is a low grade fever by rectal thermo- meter but a mid grade fever by ear or oral thermo- meter.
Annual Calendar Scale Month - 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.
Fixed Holiday Markers Fixed holidays are marked by color dots on the Calendar Scale to assist clinical scheduling near certain holidays. Christmas – red dot Halloween – orange dot Forth of July – blue dot St Patrick's Day – green dot Valentines Day – red dot New Years Day – black dot
Average Cycle Length Scale The Average Cycle Length scale automatically adjusts the position of the Last Menstrual Period (LMP) marker to compensate for variations in Menstrual Cycles In this example: LMP on January 7 for 36 day cycles LMP on January 15 for 28 day cycles LMP on January 21 for 22 day cycles
Average Cycle Length Scale The Average Cycle Length scale automatically compensates for cycle variations to greatly improve accuracy in Gestational Age and Due Date Due Date is on November 3 rd Example: LMP is on January 25 for average cycle length of 28 days
Average Cycle Length Scale Example: For LMP on January 26 th Due Date is on November 13 th if average cycle length is 38 days Due Date is on October 28 th if average cycle length is 22 days 38 22
Sperm Exposure Scale 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. Example: Intercourse between April 17 and April 25 may result in pregnancy.
Early Pregnancy Landmarks Example: For LMP on May 16 Embryo Implantation is on June 6 Missed next Menstrual Period would have been on June 13 Pregnancy test would be positive between June 10 and June 19 Ovulation is on May 30
Mid Pregnancy Landmarks Biochemical Screen – August 5 to Sept 6 Chorionic Villus Sample - August 11 to August 25 Nuchal Translucency August 22 to Sept 8 Amniocentesis Sept 8 to Sept 31 Tri/Quad Screen AFP Sept 22 to October 7 Level II Ultrasound Oct 7 to Oct 28 Early Viability – Nov 4 to Nov 18 GTT, RPR, H/H, Ab ---- Nov 18 to Dec 16 RhoGam injection Dec 16 to Dec 31 Group B strep Feb 4 to Feb 18 Example: LMP=June 3 28 day cycles
Infant Age in Days Example 2: For Birthday on October 5, infant age on June 26 is 263 days Example 1: For Birthday on October 5, infant age on December 17 is 73 days Birthday Calculate Infant Age by aligning the Birthday Marker (also the LMP 28 day marker) with babys 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. Birthday
Gestational Age Crown-Rump Length and Fetal Weight Example: On March 20 the gestational age is 8 weeks 3 days This is Day 59 of gestation, and Fetal Heart Motion should be visible on ultrasound The Crown Rump Length (CRL) should be 18 mm Fetal weight is approximately 1.5 gms 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.
Gestational Age Biparietal Diameter and Fetal Weight Example: On September 5 the gestational age is 32 weeks 2 days This is Day 226 of gestation, and CBC should be ordered. Biparietal Diameter (BPD) should be 8.3 cm Fetal Weight is approximately 1800 gms Displays the average Biparietal Diameter (in mm) and Fetal Weight (in gms) for gestational age range from 12 weeks 4 days to 42 weeks for each gestational age and corresponding calendar date.
Menstrual Period Predictor Example: For LMP on June 1, in 2 cycles the expected MP will start July st dot 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 1 st, 2 nd, 3 rd, 4 th, etc red dot to predict Menstrual Dates for 1, 2, 3, 4, etc cycles in the future. 2 nd dot Expected MP in 2 cycles
Menstrual Period Predictor Example: For current Menstrual Period on July 27, the Menstrual Period two cycles ago started on June 1. 1 st dot 2 nd dot Current MP To calculate past calendar dates of Menstrual Periods, align the cursor marker on the appropriate (1 st, 2 nd. 3 rd,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. MP 2 cycles ago
Body Mass Index Calculator Calculates the Patients 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 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/m 2 in the Overweight range
Respiration Rate Calculator Calculates patient's rate of respiration from total number of inspirations during a time period ranging from 10 seconds to 45 seconds. 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
Pulse Rate Calculator 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. 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) 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
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.
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
ECG Pulse Rate Calculator This scale calculates a patient's heart rate by measuring the distance between one or two QRS complexes on a standard ECG strip. Align the first QRS complex with the reference arrow on the scale. 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. Read heart rate (in bpm) at the position of the First or Second QRS complex, depending upon ECG paper speed.
ECG Pulse Rate Calculator 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. For Low Heart Rates (Bradycardia) Align the first QRS complex with the reference arrow on the scale.
ECG Pulse Rate Calculator 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 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 xx xx xx xx xx xx for Bradycardia for Normal Range or Tachycardia
Inch to Centimeter Converter Interconversion of Inches to Centimeters is done using the Waist-to-Hip Ratio scale in the pink field on side B. 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. 47 inches equals 120 cm
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. Calculates the Waist to Hip Ratio (WHR) from the patient's Waist Circumference and Hip Circumference (in inches or centimeters)
Waist to Hip Ratio Mortality Risk and Population Percentile by Sex 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 Example: For a Waist-to-Hip Ratio of th 55 th 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.
Pound to Kilogram Converter This feature interconverts body weight from Pounds to Kilograms, or vice versa. Align the patients body weight at the Weight in Pounds marker, then read the patient's metric body weight at the Weight in Kilograms marker. Example: 70 kg equals pounds In this example, a 154 pound patient weighs 70 kilograms.
Drug Dose Calculator by Body Weight 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. 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.
Drug Dose Calculator by Syringe Volume Rapid determination of the Syringe Volume of an injectable drug is accomplished by aligning the patient'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. Example: A patient who weighs 280 pounds needs a Pharmatropin injection. The calculated volume of Pharmatropin is 0.60 ml.
