Inspiratory Reserve Volume: Function, Role & Diseases

Inspiratory reserve volume represents the air that a patient can take in after normal inspiration during forced breathing. Together with expiratory reserve volume and respiratory volume, inspiratory reserve volume gives vital capacity. Lung volumes are measured in spirometry. What is the inspiratory reserve volume? Inspiratory reserve volume refers to inspiration and corresponds to the volume … Inspiratory Reserve Volume: Function, Role & Diseases

Breathing Depth: Function, Tasks, Role & Diseases

This article is about the depth of breath. In addition to the definition of the term, it is on the one hand about the functions and benefits. On the other hand, it will be illuminated which diseases and complaints can occur in humans in connection with the depth of breath. What is the depth of … Breathing Depth: Function, Tasks, Role & Diseases

Respiratory Time Volume: Function, Tasks, Role & Diseases

Respiratory time volume is the volume of air at ambient pressure that is inhaled and exhaled per unit time. Technically, it is the flow rate of air through the lungs per unit time, which can be measured directly or calculated as the product of respiratory volume and respiratory rate. Respiratory time volume varies widely, depending … Respiratory Time Volume: Function, Tasks, Role & Diseases

Respiratory Rest Position: Function, Tasks, Role & Diseases

The respiratory rest position exists when the opposing retractive forces of the thorax and lungs reach equilibrium and the compliance or distensibility of the lungs is at its highest. In the respiratory rest position, the lungs contain only their functional residual volume. When the lungs are overinflated, the respiratory rest position changes in a pathologic … Respiratory Rest Position: Function, Tasks, Role & Diseases

Breathing Easy: Function, Tasks, Role & Diseases

Breathing easy is a regulatory measure of the body to avoid pain. It leads to impaired performance and can result in serious complications. What is rescue breathing? Breathing gently is a regulatory action taken by the body to avoid pain. Sparing breathing is characterized by reducing the depth of breathing to avoid increasing pain by … Breathing Easy: Function, Tasks, Role & Diseases

Pulmonary function test

During the lung function test, the doctor can determine whether the lungs are working properly. Depending on the type of examination, it is measured how much air is moved through the lungs, at what speed and pressure this occurs and in what ratio the respiratory gases oxygen (O2) and carbon dioxide (CO2) are exchanged. In … Pulmonary function test

Values | Pulmonary function test

Values In order to understand which findings the physician obtains through a lung function test, one should look at the values determined. Respiratory volume (AZV): The amount of air the patient moves during normal, calm breathing (approx. 0.5 l). Inspiratory capacity (IC): The maximum volume of air the patient can breathe in after exhaling normally … Values | Pulmonary function test

Spirometry | Pulmonary function test

Spirometry Spirometry is also called the “small lung function test”. Spirometry enables the doctor to determine the vital capacity (i.e. the maximum amount of air that a person can breathe in and out) and the one-second capacity (how many liters of air are moved in one second during a strong exhalation). The measuring device, the … Spirometry | Pulmonary function test

Peak Flow | Pulmonary function test

Peak Flow Peak flow pulmonary function testing is less meaningful, but has the advantage that it can be performed by the patient himself. All the patient has to do is put his lips around the Peak Flow device, inhale and exhale as much as possible. The determined value is then read off in l/min either … Peak Flow | Pulmonary function test

Respiratory Threshold: Function, Tasks, Role & Diseases

The respiratory threshold value is the maximum respiratory time volume to be achieved and is usually calculated to one minute. Normal values average 120 to 170 liters, with age-specific variations in particular. A severely decreased respiratory threshold indicates ventilatory disorders such as hypoventilation. What is the respiratory threshold? The respiratory limit value is the maximum … Respiratory Threshold: Function, Tasks, Role & Diseases

Diffusion: Function, Tasks, Role & Diseases

Diffusion is when liquids or gases mix by means of Brownian molecular motion. In the body, diffusion occurs for the exchange of substances between cells and for the exchange of gases in the lungs. Diffusion disorders in the lungs cause respiratory insufficiency. What is diffusion? Diffusion occurs in the body for the exchange of substances … Diffusion: Function, Tasks, Role & Diseases

Breath Volume: Function, Tasks, Role & Diseases

Breath volume is the volume of air that is normally inhaled and exhaled, usually unconsciously, per breath. At rest, the volume of breath is about 500 milliliters, but it can increase to about 2.5 liters when muscles are required to work hard. Breath volume can be significantly increased by voluntary activation of the inspiratory and … Breath Volume: Function, Tasks, Role & Diseases
