3. Reference is made to the procedure signals “C”, “N”, or “NO” and “RQ” which, when used after the main s

its meaning into affirmative, negative and interrogative, respectively. (See Chapter 1, Section 6, Paragraph 3.(j), 

Example:

“MFE N” = “Bleeding is not severe”.

“MFE RQ” = “Is bleeding severe?”

INSTRUCTIONS TO MASTERS

Standard method of case description

1. The master should make a careful examination of the patient and should try to collect, as far as possible, informa

the following subjects:

(a) Description of the patient (Chapter 3, Section 2., Page 109);

(b) Previous health (Chapter 3, Section 2., Page 110);

(c) Localization of symptoms, diseases, or injuries (Chapter 3, Section 2., Page 110);

(d) General symptoms (Chapter 3, Section 2., Page 110);

(e) Particular symptoms (Chapter 3, Section 2., Page 114);

(f) *Diagnosis (Chapter 3, Section 3., Page 125).

2. Such information should be coded by choosing the appropriate groups from the corresponding sections of th

would help the recipients of the signal if the information is transmitted in the order stated in Paragraph 1.

3. Chapter 3, Section 2., Page 109, contains signals which can be used independently, i.e. with or without the desc

case.

4. After a reply from the doctor has been received and the instructions therein followed, the master can give a pr

by using signals from Chapter 3, Section 2., Page 123.

INSTRUCTIONS TO DOCTORS

1. Additional information can be requested by using Chapter 3, Section 3, Page 125.

Example:

“MQB” = “I cannot understand your signal, please use standard method of case description”.

2. For diagnosis*, Chapter 3, Section 3., Page 125, should be used.

Example:

“MQE 26” = “My probable diagnosis is cystitis”.

3. Prescribing should be limited to the “List of Medicaments” which comprises Table M-3 in Chapter 3, Section 

and 135, of the Code.

4. For special treatment, signals from Chapter 3, Section 3., Pages 125 through 127, should be used.

Example:

“MRP 4” = “Apply ice-cold compress and renew every 4 hours”.

5. When prescribing a medicament (Chapter 3, Section 3., page 127) three signals should be used as follows:

(a) the first (Chapter 3, Section 3., Page 127, and Table M-3 in Chapter 3, Section 4, Pages 134 and 135) to si

dicament itself.

* Chapter 3, Section 3, Page 125 , “Diagnosis”, can be used by both the master (“request for medical assist

and the doctor (“medical advice”).

CHAPTER 3.—MEDICAL SIGNAL CODE

Example:

“MTD 32” = “You should give aspirin tablets”.

(b) the second (Chapter 3, Section 3, Page 127) to signify the method of administration and dose.

Example:

“MTI 2” = “You should give by mouth 2 tablets/capsules”.

(c) the third (Chapter 3, Section 3, Page 127) to signify the frequency of the dose.

Example:

“MTQ 8” = “You should repeat every 8 hours”.

6. The frequency of external applications is coded in Chapter 3, Section 3, Page 128.

Example:

“MTU 4” = “You should apply every 4 hours”.

7. Advice concerning diet can be given by using signals from Chapter 3, Section 3, Page 128.

Example:

“MUC” = “Give water only in small quantities”.
