Question

Describe a scenario that could result in microshock. Identify the power source and describe how the current travels through the patient. Describe the conditions under which electrical current can be used to correct the electrical signals of the heart. Mark a list of some of the guidelines related to equipment power cords. Make list of some of the guidelines related to equipment power cords. Make a list of some of the guidelines related to power outlets. Make a chart that shows the currents necessary to trigger the action of a LIM and a CFCI. Include a column that shows whether the circuit is open or closed above the trigger currents. Summarize NFPA 101 requirements. Describe the role of the federal government in medical equipment regulations. Summarize how HIPPA impacts what BMETs do.

Explanation / Answer

(2). An electrically susceptible patient (i.e., one who has a direct, external connection to the heart, such as through a central venous pressure catheter or transvenous cardiac pacing wires) may be at risk from very small currents; this is called microshock. microshock involves relatively small amounts of current applied to the surface of the body. The current is conducted through all the tissues in proportion to their conductivity and area in a plane perpendicular to the current.

(3).   Doctors use a test called an EKG (electrocardiogram) to help diagnose heart block. This test detects and records the heart's electrical activity. An EKG records the strength and timing of electrical signals as they pass through the heart.

From the SA node, the signal travels through the right and left atria. This causes the atria to contract, which helps move blood into the heart's lower chambers, the ventricles (VEN-trih-kuls). The electrical signal moving through the atria is recorded as the P wave on the EKG.

(4). (i) If there is a defect or evidence of damage that might expose an employee to injury, the defective or damaged item shall be removed from service, and no employee may use it until repairs and tests necessary to render the equipment safe have been made.

(ii).   Energized plug and receptacle connections may be handled only with insulating protective equipment if the condition of the connection could provide a conducting path to the employee's hand (if, for example, a cord connector is wet from being immersed in water).
