Accessory pathways are often diagnosed using an electrocardiogram, but characterisation and location of the pathway may require an electrophysiological study. Accessory pathways may not require any treatment, but those causing symptoms may be treated with medication including calcium channel antagonists , beta blockers or flecainide . [ 3 ]
The Mynx vascular closure device is an extravascular vascular closure device (VCD) whose deployment system is designed to minimize the discomfort commonly associated with closing the small hole in the artery following catheterization procedure.
A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
Control panel for a Boeing 737-800 ECS. In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics, smoke detection, and fire suppression.
A dull, muffled sound may replace resonance in conditions like pneumonia or hemothorax. Hyper-resonance: Very loud, very low pitch, and longer in duration. Abnormal. [14] Hyper-resonance can result from asthma or emphysema; Tympany: Loud and high pitched. Common for percussion over gas-filled spaces. [14] Tympany may result in pneumothorax. [15]
The most basic form monitors the heart's native electrical rhythm. When the pacemaker wire or "lead" does not detect heart electrical activity in the chamber – atrium or ventricle – within a normal beat-to-beat time period – most commonly one second – it will stimulate either the atrium or the ventricle with a short low voltage pulse.
One component of the heart-lung machine is the oxygenator. The oxygenator component serves as the lung, and is designed to expose the blood to oxygen and remove carbon dioxide. It is disposable and contains about 2–4 m² of a membrane permeable to gas but impermeable to blood , in the form of hollow fibers. [ 2 ]
Wolff–Parkinson–White syndrome (WPWS) is a disorder due to a specific type of problem with the electrical system of the heart involving an accessory pathway able to conduct electrical current between the atria and the ventricles, thus bypassing the atrioventricular node.
