Respiratory rate (pulmonary ventilation rate or ventilation rate, breathing frequency (BF)) is the number of breaths a living being, such as a human, takes within a certain amount of time (frequently given in breaths per minute).
- Newborns: Average 44 breaths per minute
- Infants: 40-60 breaths per minute
- Preschool children: 20–30 breaths per minute
- Older children: 16–25 breaths per minute
- Adults: 12–20 breaths per minute
- Adults during strenuous exercise 35–45 breaths per minute
- Athletes' peak 60–70 breaths per minute
It is simply possible to measure number of cycle per minute.
- this take more time
- accuracy depend upon user
2. Multi measurement monitor
RR Imp Respiration Rate measured using change of Impedance across the ECG leads RA (Right Arm) and LL (Left Leg)
|Proper Leads placement|
|Three Leads Placement|
- If values not shown on monitor Check RA and LA properly place as shown above
2.2 Side stream CO2
This also widely used to measure RR of ventilated patients.
