Computer-aided emergency telecommunications for the deaf
Annals of Emergency Medicine
|June 1, 1982
Abstract:
Computer-aided telecommunications provide deaf teletypewriter users with 24-hour toll-free access to emergency services. An interface and software link the deaf caller's teletypewriter (TDD) with a microprocessor by reducing and inverting voltage levels between the two devices. This system facilitates rapid transmission of linguistically controlled triage questions to meet the communication needs of deaf patients.

01:19Contact-dependent Signaling
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

01:23Cardiopulmonary Resuscitation III: AED Use
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...
