Manifestations: Breathing patterns are often irregular and shallow. The infants respiration rate should be between 30 and 60 breaths per minute with preference for nasal breathing. Ribs expands horizontally. Breath sounds should be clear and equal in both lungs. Abdominal breathing is normal. Acrocyanosis is a normal finding. [1]
This gives the lower of the average rate at 12 breaths per minute. Average resting respiratory rates by age are: [11] [self-published source] [12] birth to 6 weeks: 30–40 breaths per minute; 6 months: 25–40 breaths per minute; 3 years: 20–30 breaths per minute; 6 years: 18–25 breaths per minute; 10 years: 17–23 breaths per minute
After first 5 breaths, if effective, it is also advisable to search for signs such movements, coughing, shortness and possibly only the presence of pulse, for less than 10 seconds. [citation needed] if there are signs of circulation or a heart rate greater than 60 continue ventilations with a rate of 20 per minute.
The set frequency is displayed on a digital meter on the face of the ventilator. One Hertz is (-/+5%) equal to 1 breath per second, or 60 breaths per minute (e.g., 10 Hz = 600 breaths per minute). Changes in frequency are inversely proportional to the amplitude and thus delivered tidal volume. Breaths per minute (f)
CPR consists of chest compressions followed by rescue breaths - for single rescuer do 30 compressions and 2 breaths (30:2), for > 2 rescuers do 15 compressions and 2 breaths (15:2). The rate of chest compressions should be 100-120 compressions/min and depth should be 1.5 inches for infants and 2 inches for children.
TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)
A normal minute volume while resting is about 5–8 liters per minute in humans. [1] Minute volume generally decreases when at rest, and increases with exercise. For example, during light activities minute volume may be around 12 litres. Riding a bicycle increases minute ventilation by a factor of 2 to 4 depending on the level of exercise involved.
