Invasive Ventilatory Support Modes
where PR is the pressure required to overcome RAW and PE the pressure required to overcome E. During PPV, the driving pressure for air to flow is applied by the…
Pulse Oximetry, Plethysmography, Capnography, and Respiratory Monitoring
Rearranging the equation to employ the measured ratio of transmitted to incident light, we can define absorbance (A) as: The absorption coefficient (a) is unique value for each wavelength and…
Mechanical Ventilation
FIGURE 102.1 The effects of gravity on ventilation–perfusion ratio (VA/Q). In the upright subject, gravity affects VA, Q, and concomitantly, the VA/Q ratio. Gravitational forces pull on both the gases…
Important Intensive Care Procedures
