Best Respiration Flow Meters Buying Guide
Before choosing the best respiration flow meter you should consider following options:
1. Accuracy: The accuracy of the meter is one of the most important factors to consider. The accuracy of the meter is expressed in terms of the margin of error. It is expressed as a percentage of the reading given by the meter.
A meter with a margin of error of + / – 1% is considered to be an accurate meter.
2. Resolution: Resolution is expressed in terms of the smallest unit of the reading in the meter. It is expressed as a ratio with a denominator of 1000.
For example, if a meter has a resolution of 0.1 L/min, it means that the smallest unit of the reading is 0.1 L/min or 10 ml/min.
3. Calibration: It is always important to check the calibration of the meter before use. If the calibration is not done correctly, the readings could be off.
Inaccurate readings could lead to improper treatment of the patient who is using the meter. The calibration date and the name of the person who calibrated the meter should be clearly printed on the meter.
4. Power source: The type of power source used to operate the meter is also an important factor to consider.
Some meters operate on batteries while others operate on a plug-in connection. Some meters have a combination of both. If the power source is batteries, ensure that the batteries are the right size and that there are enough of them in the meter.
5. Features: The features of the meter are also very important to consider. Some features that are worth considering include alarm buttons and the ability to calculate the SpO2.
6. Ease of use: The meter should be easy to use. The buttons and touchscreen should be easy to operate. The display should also be easy to read.
7. Cost: The cost of the meter is another important factor to consider. The cost could vary depending on the features of the meter and the quality of the meter.
