Principles Patient Monitoring Flashcards
What does SpO2 to stand for
Saturation
Pulsatile (pulse)
Oxygen
Non-invasive blood-pressure may reflect only what
Mean blood pressure
What monitors are we monitoring of the patient
ECG Blood-pressure Temperature Oximetry Cardiac output
What monitors are measured by the anesthesia delivery system
Pipeline pressure
Cylinder pressures
Inspired O2
Oxygen failure alarm
What parameters are measured both from the patient and from the anesthesia delivery machine
Peak airway pressure
Airway flow
Tidal volume
Respiratory gas analysis
What is the ASA motto
Vigilance
Which alarm requires awareness and consist of one or two slow pulses
Low (advisory) alarm
What organization sets forth the auditory alarms and priorities
International electrotechnical commission (IEC)
The medium (caution) alarm consists of what
Three faster pulses that may repeat and something that requires prompt response
What auditory sound requires immediate response and consist of ten rapid pulses that repeats in a pattern of five
The high (warning) alarm
How many decibels difference should be between the sound levels High>medium>low
3dB
In the problem resolution chart, the farther along the system from the machines to the pt that a parameter is measured, The delay is greater or smaller?
The greater the delay before the problem is correct
What is the measurement theory
Measured value= True value+ ( Systemic error + Random error)
Which of the values do we not really know In the measurement theory
True value
Systemic errors or biased errors are what
Predictable and may be compensated by adding or subtracting a constant
What is the random error
Unpredictable and when averaging repeated measurement tends to reduce or eliminate random errors
What is the accuracy of the measurement
Closeness of the agreement between the measured value and the true value
What is the degree of consistency between repeated measurements of the same quantity
Precision
Reproducibility is what
The ability to maintain precision during long-term use
What is the likelihood that when an abnormal situation occurs it will be detected
Sensitivity
Specificity signifies what
The likelihood that when the situation is normal no event will be indicated
Which type of monitoring is susceptible to drift
Invasive monitoring
What things determine the sensitivity and specificity in the system
The characteristic of the signal
The mechanics of the sensor
Mechanics of the artifact rejection
Programming by the user
Which type of monitoring is susceptible to ringing
Artline
What is the name of the plot for the comparison of two cardiac output techniques
Bland Altman plot
Cardiac output devices are more often than not what type of device
Thermo dilution device
What is drift when determining the quality of measurement
Slow low-frequency components of the signal and is a lower frequency than the signal
What is the time that it takes for the instrument to get from 10% to 90% of the complete response
Rise time
Any unwanted interference or unwanted signals that may interfere with the measurement is known as what
Noise
60 bpm is equivalent to how many hertz
One hertz
