An adult at rest has a heart rate (HR) between 60 and 100 beats per minute.
(BPM), and a respiratory rate (RR) of 12 to 18 breaths per minute (BPM).
The monitoring system in an Intensive Care Unit (ICU) requires knowing the value of these physiological variables at all times and notifying the staff when these values are outside the normal range, through visual or auditory alarms.
Using a minimum of two stages, design a conditioning circuit to know the value of the respiratory rate by using a sensor with an input range of 0 to 60 RPM, and an output range of 0.5 to 3V. Considerations:
-The output will be measured in a multimeter, using 2 digits, in such a way that the user can
easily know the HR or FR of the patient.
-Only one power supply with two channels is available
-Use only commercial value resistors
-The op-amps must be polarized with 30V. (+15V, -15V)
-The use of buffers is not counted in the total of the stages.
