The peak flow meter will accurately measure the peak expiratory flow rate (PEFR), or how quickly air is leaving the lungs. Instant readings help track changes in airflow. Compact design for Discreet use. Assists detection of a pending asthma attack. The dual-flow range accurately measures for both adults & children. There will be a serious shortage of oxygen supply, resulting in adverse reactions such as headache, dizziness, chest tightness, listlessness, etc.

Quality Material - Peak flow is a portable, handheld device for measuring your ability to exhalate air from the lungs, and can provide correct data to reflect the ventilation of the trachea.
The importance of vital capacity - The vital capacity of the lung is closely related to human respiration. Physiological studies show that the organs, systems, tissues, and organs of the human body.
Easy to use - Peak expiratory flow indicating that the body oxygen uptake and exhaust, the oxygen supply inside the body is not sufficient, once the body needs a lot of oxygen consumption situation (such as long-time learning, work, strenuous exercise) there will be a serious shortage of oxygen supply, resulting in adverse reactions such as headache, dizziness, chest tightness, listlessness, inattention, memory loss, insomnia, this will not only affect the learning and work, and will cause many irreparable losses to health.
Vital capacity - This refers to the total amount of gas that can be exhaled at a time when you try to breathe in. Adult men's vital capacity is about 3500-4000 milliliters, and women are about 2500-3000 milliliters. The better the health is, the greater the vital capacity is.
Easy to clean & reusable - Accurate handheld respiratory flowmeter gives a direct readout of maximal expiratory flow rate (MFR) from a single forced exhalation. Measures respiratory flow up to 900 L/min; cleans easily with soap and water. It comes with a reusable mouthpiece and instruction manual.
