Vintage Manual Ventilation: The 1,500 mL BVM (Bag-Valve-Mask Manual Resuscitator)

Although the device still works as designed, is still in service and being used by well-intentioned clinicians, it should be on the shelf with the Medical Anti-Shock Trousers, LifePak 5 and Biophone. While change is sometimes slow, and healthcare providers can be described as conservatively fixed, lung protective ventilation is the current standard of care. 

Waveform Assessment & High ETCO2

Capnography is the only tool in the universe that is non-invasive, in real time and simultaneously assesses a patient’s airway patency, quality of breathing, perfusion/shock status and metabolic state.  How does it work?  What does the waveform tell you vs....

Pulse Oximetry, ETCO2 and PaCO2

While quantitative waveform capnography and pulse oximetry are both infrared technologies and may seem like similar measurements, they assess very different things.  Capnography is a direct measurement of ventilation and, indirectly, circulatory and metabolic...
