WebbThe "Shark fin" waveform on EtCO2 is the hallmark of bronchospasm-common in bronchitis, asthma, emphysema. Phase I: When you read your waveform, you start from the baseline, (lowest level of the waveform), which represent the "Inspiratory Phase", which is when the CO2 in your airways is at it's lowest and it is not hitting the sensor. WebbIn brief, the dimmer uses an astable 555 timer to produce a "shark fin" waveform which is sent to an op-amp comparator that uses a variable voltage set by the dimmer potentiometer to adjust duty cycle. The output of the comparator goes to a PWM optimized FET to supply the LEDs at the output.
