An incentive spirometer is a handheld medical device used to help patients improve the functioning of their lungs.By training patients to take slow and deep breaths, this simplified spirometer facilitates lung expansion and strengthening.
Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
In 1960, the European Community for Coal and Steel (ECCS) first recommended guidelines for spirometry. [7] The organization then published predicted values for parameters such as spirometric indices, residual volume, total lung capacity, and functional residual capacity in 1971. [ 8 ]
Wiggers diagram with mechanical (echo), electrical (ECG), and aortic pressure (catheter) waveforms, together with an in-ear dynamic pressure waveform measured using a novel infrasonic hemodynography technology, for a patient with severe aortic stenosis.
Each Holter system has hardware (called monitor or recorder) for recording the signal, and software for review and analysis of the record. There may be a "patient button" on the front that the patient can press at specific instants such as feeling/being sick, going to bed, taking pills, marking an event of symptoms which is then documented in the symptoms diary, etc.; this records a mark that ...

Echocardiography is widely used in an array of patients ranging from those experiencing symptoms, such as shortness of breath or chest pain, to those undergoing cancer treatments.
The device returns a preliminary analysis of the ECG recording, and detailed data can be later on shown to a physician. [15] 6. Lithuanian company ZIVE, created a single-channel ECG monitor (3 channel optional), that transmits data to iOS or Android phone. Live ECG and full ECG analysis options are available. Device is Class II CE EU certified ...
Stress and potential cardiac damage from exercise during the test is a problem in patients with ECG abnormalities at rest or in patients with severe motor disability. Pharmacological stimulation from vasodilators such as dipyridamole or adenosine, or positive chronotropic agents such as dobutamine can be used.
