Peak Flow Meter for Asthma What is a peak flow meter? A peak flow meter is a small device that you blow into. It measures the fastest rate of air (airflow) that you can blow out of your lungs. It records airflow in litres per minute (L/min). Your doctor may prescribe a peak flow meter for you if you have asthma. There are different brands of peak flow meter.

- Spirometric values. FVC—Forced vital capacity; the total volume of air that can be exhaled during a maximal forced expiration effort. FEV 1 —Forced expiratory volume in one second; the volume of air exhaled in the first second under force after a maximal inhalation.FEV 1 / FVC ratio—The percentage of the FVC expired in one second.pirometry measures the rate at which the lung changes volume during forced breathing maneuvers. Spirometry begins with a full inhalation, followed by a forced expiration that rapidly empties the lungs. Expiration is continued for as long as possible or until a plateau in exhaled volume is reached.

- An accelerometer is a device that measures proper acceleration. Proper acceleration, being the acceleration (or rate of change of velocity) of a body in its own instantaneous rest frame, is not the same as coordinate acceleration, being the acceleration in a fixed coordinate system.

Spirometry Spirometry is a test that can help diagnose various lung conditions, most commonly chronic obstructive pulmonary disease (COPD). Spirometry is also used to monitor the severity of some other lung conditions, and their response to treatment. Note: the information below is a general guide only.

- Respirometer by Philip HarrisThis investigation involves handling whole living organisms and provides a quantitative method of exploring metabolism. Measurements of gas exchange, particularly the rate of uptake of oxygen, give a clear indication of the activity of respiratory metabolism. The equipment used is called a respirometer – not to be confused with a spirometer. You can use respirometers to measure the uptake of oxygen by respiring mung beans or other small amounts of living material.

Counting Respiration Rate The respiration rate is the rate at which a person breathes. It increases with fever and some illnesses. The best time to count the respiration rate is when a person is resting, perhaps after you take the person's pulse while your fingers are still on the person's wrist.

- Measuring respirations. The respiratory rate is the number of breaths that a patient takes each minute. The rate should be taken when the patient is at rest, and it is assessed by counting the number of times the chest rises in one minute. Common factors that influence respiration rate are as follows:

Pulse oximetry Pulse oximetry is a non-invasive method for monitoring a person's O 2 saturation. In its most common (transmissive) application mode, a sensor device is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of an infant, across a foot.ith the introduction of pulse oximetry, a non-invasive, continuous measure of patient's oxygenation was possible, revolutionizing the practice of anesthesia and greatly improving patient safety.

Pulse oximetry A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram.lthough a pulse oximeter is used to monitor oxygenation, it cannot determine the metabolism of oxygen, or the amount of oxygen being used by a patient. For this purpose, it is necessary to also measure carbon dioxide (CO 2) levels.

Spirometry Spirometry is a simple test used to help diagnose and monitor certain lung conditions by measuring how much air you can breathe out in one forced breath.It's carried out using a device called a spirometer, which is a small machine attached by a cable to a mouthpiece.pirometry can be used to help diagnose a lung condition if you have symptoms of a problem, or your doctor feels you're at an increased risk of developing a particular lung condition.

- Doing a spirometry. Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs), measuring lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.verage values for forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and forced expiratory flow 25–75% (FEF25–75%), according to a study in the United States 2007 of 3,600 subjects aged 4–80 years.

What Tests Can Be Used to Estimate Cardiorespiratory Fitness? Spirometry is a lung capacity test that also measures how quickly you can exhale. Doctors use it to test for a variety of conditions, including asthma, chronic obstructive pulmonary disease and emphysema. However, it also offers a general measure of cardiorespiratory fitness. During the test, a doctor or nurse clips your nose shut and then uses a machine to measure your breathing as you inhale and exhale. You will have to inhale deeply and slowly and then exhale as forcefully as you can several times.

Overview Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale. Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing.Spirometry may also be used periodically to check whether a treatment for a chronic lung condition is helping you breathe better.1  Why it's done.pirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing.

Pulse Oximetry What is pulse oximetry? Pulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs. A clip-like device called a probe is placed on a body part, such as a finger or ear lobe.

Peak expiratory flow The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air.ue to the wide range of ‘normal' values and high degree of variability, peak flow is not the recommended test to identify asthma. However, it can be useful in some circumstances. A small portion of people with asthma may benefit from regular peak flow monitoring.

breath breath volume. may be assessed by observation of degree of chest movement and volume of expired air as felt by the hand. A respirometer is more accurate but is not available nor satisfactory for clinical use with animals unless the subject is trained to use one.

- Peak Expiratory Flow Rate (PEFR) Technique. Peak expiratory flow rate is the measurement of how much the patient can blow out of their lungs in one breath. It is a crude measurement and not as accurate as Spirometry. However it is useful for patients to perform themselves, especially when they are having a flare up of their respiratory disease e.g. asthma.

What is Spectrophotometer? A spectrophotometer is an instrument which is used to measure the intensity of electromagnetic radiation at different wavelengths. Important features of spectrophotometers are spectral band with and the range of absorption or reflectance measurement.pectrophotometry is a quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. It is more specific than the common term electromagnetic spectroscopy which deals with visible light near ultraviolet and near infra-red.
