Study Notes
Thoracic Compliance
- Calculated as Tidal Volume / (Plateu pressure - PEEP)
Work of Breathing on Ventilator
- More with Pressure triggering
Blood Gas Analyzer Standby Mode
- Saves both current and chemicals
Mechanical Ventilator EST
- Performed each time before applying on a new patient
- Also done during servicing
Computer Keyboard and Mouse
- Act as input devices
Window Operating System
- None of the listed options are correct (memory driven, AC driven, voltage driven)
Reference Electrode in Blood Gas Analyzer
- A cathode
Oxygen Concentrator
- Better applied at home
ICU Room Disinfection
- May be done using Ozone gas, UV Germicidal light, or a combination of both
Stochastic Signal
- Example: ECG in multi-channel monitor
NRBM Valve
- One way
Transport Ventilator FIO2
- Achieved by regulation of O2 flow at the source and by using a blender
