main Spirometry Image LungVolume.jpg thumb 600px Output of a spirometer Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inspiration. It is equal to the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume. A person s vital capacity can be measured by a spirometer which can be a wet or regular spirometry spirometer . In combination with other physiological measurements, the vital capacity can help make a diagnosis of underlying lung disease. The unit that is used to determine this vital capacity is the millilitre ml . A normal adult has a vital capacity between 3 and 5 litres. After the age of 20 the vital capacity decreases approximately 250 cc per ten years.

A bronchial challenge test is a medical test used to assist in the diagnosis of asthma . ref PMID 6827612 ref The patient breathes in nebulizer nebulized methacholine or histamine . Thus the test may also be called a methacholine challenge test or histamine challenge test respectively. Both drugs provoke bronchoconstriction , or narrowing of the airways. Whereas histamine causes nasal and bronchial mucus secretion and bronchoconstriction via the H1 receptor , methacholine utilizes the M3 receptor for bronchoconstriction. The degree of narrowing can then be quantified by spirometry . People with pre existing airway hyperreactivity, such as asthmatics, will react to lower doses of drug. Sometimes, to assess the reversibility of a particular condition, a bronchodilator is administered to counteract the effects of the bronchoconstrictor before repeating the spirometry tests. This is commonly referred to as a reversibility test , or a post bronchodilator test post BD , and may help in distinguishing asthma from chronic obstructive pulmonary disease . False positives and negatives are possible in the bronchial challenge test. In addition, asthma may be temporary due to an exposure to noxious stimuli or exercise. The bronchial challenge test is physically demanding, and the results can be affected by muscular weakness or exhaustion. The inhaled drug can stimulate the upper airway sufficiently to cause violent coughing. This can make spirometry difficult or impossible. This test is contraindicated in patients with severe airway obstruction due to the obvious worsening of the obstruction.

A lung function test or pulmonary function test PFT is a test to measure the functionality of the human lung lungs . Examples Spirometry , using a spirometer , is the most common of the pulmonary function tests, measuring lung function, specifically the measurement of the amount volume and or speed flow of air that can be inhaled and exhaled. Body plethysmography is a very sensitive lung measurement used to detect lung pathology that might be missed with conventional pulmonary function tests. This method of obtaining the absolute volume of air within one s lungs may also be used in situations where several repeated trials are required or where the patient is unable to perform the multibreath tests. Peak expiratory flow may, in addition to the spirometer , be measured with a more handy peak flow meter . Nitrogen washout or Fowler s method is a test for measuring dead space in the lung during a respiratory cycle, as well as some unique parameters related to the closure of airways. A ventilation perfusion lung scan , also called a V Q lung scan, uses scintigraphy and Nuclear medicine medical isotopes to evaluate the circulation of air and blood within a patient s lungs , ref http www.umm.edu ency article 003828.htm ref in order to determine the ventilation perfusion ratio .

Infobox Disease Name Airway obstruction Image Caption DiseasesDB ICD10 ICD9 ICDO OMIM MedlinePlus eMedicineSubj eMedicineTopic MeshID D000402 Unreferenced date June 2008 Airway obstruction is a Respiration physiology respiratory problem caused by increased resistance in the bronchiole s usually from a decreased radius of the bronchioles that reduces the amount of air inhaled in each breath and the Breathing gas oxygen that reaches the Pulmonary artery pulmonary arteries . It is different from airway restriction which prevents air from diffusing into the pulmonary arteries because of some kind of blockage in the lungs . Diagnosis Obstruction can be measured using spirometry . A decreased FEV1 FVC ratio versus the normal of about 80 is indicative of an airway obstruction, as the normal amount of air can no longer be exhaled in the first second of expiration. An airway restriction would not produce a reduced FEV1 FVC ratio, would produce a reduced vital capacity . The ventilation is therefore affected leading to a ventilation perfusion mismatch and hypoxia.

Image LungVolume.jpg thumb 400px Lung Volumes Functional Residual Capacity FRC is the volume of air present in the lungs , specifically the parenchyma tissues, at the end of passive expiration . At FRC, the elastic recoil forces of the lungs and chest wall are equal but opposite and there is no exertion by the thoracic diaphragm diaphragm or other respiratory muscles. FRC is the sum of Expiratory reserve volume Expiratory Reserve Volume ERV and Residual Volume RV and measures approximately 2400 ml in a 70 kg, average sized male. It can not be estimated through spirometry , since it includes the residual volume. In order to measure RV precisely, one would need to perform a test such as nitrogen washout , Helium dilution technique helium dilution or body plethysmography . A lowered or elevated FRC is often an indication of some form of respiratory disease . For instance, in emphysema , the lungs are more compliance physiology compliant and therefore are more susceptible to the outward recoil forces of the chest wall. Emphysema patients often have noticeably broader chests because they are breathing at larger volumes. The helium dilution technique is a common way of measuring the functional residual capacity of the lungs.

This article is about the physical measurement. For other uses of the term, see Reach Arm span or reach also known as wingspan is the physical measurement of the length from one end of an individual s arm s measured at the finger tips to the other when raised Parallel geometry parallel to the ground at shoulder height at a one hundred eighty degree angle. The average reach correlates to the human height person s height . Advantages An above average reach is advantageous in sports such as basketball , boxing , and Human swimming swimming . For instance, boxer Sonny Liston had an convert 84 in cm 0 adj on reach despite being only convert 72 1 2 in cm 0 in height. This unusually long reach allowed him to hit opposing boxers from relatively safe distances where they could not reach him. Disadvantages Because any decrease in height will cause an increase in the ratio of arm span to height, a large span to height ratio may sometimes be an indicator of a health problem that has caused a decrease in height Procedure To measure the arm span, the person must be standing up against the wall with their arms extended sideways at a ninety degree angle. A person with a length measuring tool usually a tape measure will measure from one end of the tip of the finger to the other. This method can be easily done at home and it is not necessary to see a physician, unless for a checkup. See also Wingspan Reference Cite journal last Tan first P.

Nofootnotes date August 2010 Air trapping , also called gas trapping , is an abnormal retention of air in the lungs after expiration. It is observed in obstructive lung diseases such as asthma , bronchiolitis obliterans syndrome and chronic obstructive pulmonary disease . The cause is obstruction such that the patient is unable to expel air completely. Air trapping is a cause of obstructive pattern spirometry results, leading to an elevated residual volume . Air trapping is often incidentally diagnosed on computed tomography CT scanning. The only way to absolutely differentiate air trapping from emphysema is by taking expiratory images. On expiratory films, retained hyperlucent gas will be visualised in cases of air trapping. Air trapping represents poorly aerated lung, but on its own is clinically benign. It is a common problem for smokers who dive. On diving the lung volume collapses and pushes air into the poorly aerated regions. On arising from a deep depth, these air trapped areas of lung expand. This places great pressure on the lung tissue which can rupture. References Javier Lucaya A. L. Baert Janet L.

orphan date September 2010 The MET call Medical Emergency Team was designed at the Liverpool Hospital , Sydney , Australia in 1990 and has continued to develop and spread around Australia. The MET call is a hospital based system, designed for a nurse or other staff member to alert and call other staff for help when a patients vital signs have fallen outside set criteria. These criteria were designed around studies suggesting that certain vital sign ranges and symptoms occur before poor patient conditions which may lead to death For example, Chest pain , a raise in heart rate and an elevated blood pressure may indicate the patient may be about to have a heart attack . In the original model, the criteria also include and any patient you are seriously worried about , although this is not included in all hospitals. The MET call is generally made by a phone call e.g. to switch . On the ward it may be via an emergency button on the wall, which sounds a siren , and in some hospitals, a red light will begin flashing outside the patients room. Most staff are encouraged to attend and help as required. Interventions and tests that the MET call may include Oxygen via a mask , Blood glucose levels, CPAP Continuous positive airway pressure , X ray , ECG , Vital signs, documentation and Spirometry . Two to three trained professionals arrive at the room of the Emergency, and will work together with staff to assist the patient, as well as Physician doctor s, nurses and anyone who is able to help. Jobs are allocated including someone to record the nature of emergency and what they are doing to fix the problem. Some patients may be transferred to Intensive Care Unit ICU post MET. Implementation of the MET system has been controversial. It generally requires ICU medical and nursing staff to move beyond their traditional boundaries of control. It implies extra work, although arguably reduces the workload of patients arriving in ICU. Studies such as the MERIT study have been inconclusive ... more details
