  • Balances: Use and Principles of Operation 
    Malkin, Robert (EWH, 2006)
    Balances are accurate and precise instruments used to measure the weight or mass of a substance or material. The ability to measure material as large as 50kg and as small as 10μg makes them quite common. There are two ...
  • Batteries: Clinical Use and Principles of Operation 
    Malkin, Robert (2006)
    While not a medical device in itself, the battery, like the generator, is often the source of problems in developing world hospital equipment. The battery comes in a wide variety of forms and can be used to provide electrical ...
  • Clinical Laboratory Ovens Use and Principles of Operation 
    Malkin, Robert (EWH, 2006)
    Ovens in laboratories are used to dry samples and for evaporating, dehydrating or sterilizing. On a limited basis some are used as a dry incubator. In many cases, precise temperature control is required. Clinical ovens ...
  • Clinical Use and Principles of Operation of Bottle Gasses 
    Malkin, Robert (EWH, 2006)

  • Clinical Use and Principles of Operation: Ventilators 
    Malkin, Robert (EWH, 2006)
    Many patients in an intensive care and the operating room require the mechanical ventilation of their lungs. All thoracic surgery patients, for example, require mechanical ventilation. Some patients simply need assistance ...
  • Defibrillators: Clinical Use and Principles of Operation 
    Malkin, Robert (EWH, 2006)
    A defibrillator is used to reverse fibrillation of the heart, restoring the heart’s normally coordinated contractions. The uncoordinated contractions of the heart can take place in the atrial, or upper, chamber of the heart ...
  • Electrocardiographs: Clinical Use and Principles of Operation 
    Malkin, Robert (Engineering World Health (EWH), 2006)

  • Equipment Found in OR, ICU and ER 
    Malkin, Robert (2006)
    In the developing world, the biomedical engineer will often be called into an active room to do a quick repair or adjustment. You will need to know what procedures to follow. Procedures will vary from hospital to hospital ...
  • Fetal Monitor and Fetal Doppler Clinical Use and Principles of Operation 
    Malkin, Robert (2006)
    Fetal monitors document two major functions: 1) the heart rate of the fetus, and 2) the contractions of the mother. A normal fetal heart rate is between 110 to 160 beats a minute. The sound of the beat is usually strong ...
