Example: MTI 2—You should give by mouth two tablets/capsules. 3. The third (chapter 3, section 3D-3) signifies the frequency of the dose. Example: MTQ 8—You should repeat every 8 hours. The frequency of external applications is coded in chapter 3, section 3D-4. Example: MTU 4—You should apply every 4 hours. Advice concerning diet can be given by using signals from chapter 3, section 3E. Example: MUC—Give water only in small quantities. As an example, two cases of request for assistance and the corresponding replies follow: CASE ONE REQUEST FOR MEDICAL ASSISTANCE. “I have a male age 44 years. Patient has been ill for 2 days.

Patient should be seen by doctor when next in port.” DISTRESS AND LIFESAVING SIGNALS LEARNING OBJECTIVES: List and define distress and lifesaving signals. Explain distress transmitting procedures. Chapter 4 of the International Code of Signals covers distress signals, lifesaving signals, and distress radiotelephone transmitting procedures. DISTRESS/LIFESAVING The following signals, to be used or displayed either together or separately, indicate distress and need of assistance (see fig. 6-2): A gun or other explosive signal fired at intervals of about a minute A continuous sounding with any fog-signaling apparatus Rockets or shells, throwing red stars fired one at a time at short intervals A signal made by radiotelegraphy or by any other signaling method consisting of the group ...---...
