How are medical robots used?
By: Bill Fitzgerald
Imagine a surgeon who can perform surgery with extreme precision, smaller incisions, decreased blood loss, less pain, and quicker healing time. That is one of the primary roles of robotics in modern medicine. Although technically considered to be teleoperated devices, robotic surgical system such as...
Positron emission tomography: The PET scan explained
By: Bill Fitzgerald
Positron emission tomography is an imaging test that uses a small amount of radioactive material (radiotracer) to show how your tissues and organs are functioning. The radiotracer can be injected, taken orally, or inhaled; the method of delivery and the amount of radiotracer will depend...

Middle ear infections are a common ailment for young children, most often between ages six months and two years. Generally, ear infections clear up in a few weeks and some can be treated with antibiotics. However, when a child has recurrent or severe ear infections...
Knowing when to adjust mechanical ventilator settings in the ICU
By: Nicole Evans M.D.
“Knowing when to adjust mechanical ventilator settings” is the third article in a series of articles written to help medical students understand mechanical ventilation. If you already get the basics of mechanical ventilation (FiO2, PEEP, tidal volume, RR), please read on. If you do...
How to determine the initial settings for mechanical ventilation
By: Nicole Evans M.D.
Physicians who find themselves caring for a patient on mechanical ventilation must be familiar with ventilator function and settings. Altering various aspects of the mechanical ventilator will allow a physician to achieve the two basic goals of mechanical ventilation: 1. Control the oxygen and carbon...
Best place to insert a Swan Ganz catheter
By: Nicole Evans M.D.
Flow-directed pulmonary artery catheters are used as an invasive method to monitor hemodynamic status in critically ill patients and in diagnostic and therapeutic procedures in cardiology. Pulmonary artery (PA) catheters are also called Swan-Ganz catheters. The placement of a pulmonary artery catheter is invasive. The...
Uses of pulmonary artery Swan Ganz catheters
By: Nicole Evans M.D.
Flow-directed pulmonary artery catheters are used as an invasive method to monitor hemodynamic status in critically ill patients and in diagnostic and therapeutic procedures in cardiology. Pulmonary artery (PA) catheters are also called Swan-Ganz catheters. PA catheters can directly measure: -Central venous pressure (CVP) -Right-sided...

How brain scans work... *Have you ever had a brain scan? Have you ever had a brain scan? Did they ever explain how the brain scan they were using worked? Doctors order brain scans all the time but "no-one" ever explains to the patient how...
How brain scans work
By: Arlene Miles
Brain scans are imaging tests of the head that are used to diagnose possible injury or disease. The most common rain scan technologies are computed axial tomography (CAT), position emission tomography (PET), magnetic resonance imaging (MRI), Functional MRI (fMRI), Electroencephalography (EEG), and Magnetoencephalography (MEG). Brain...
