Heimlich valve: The flutter valve functions by allowing only outwards airflow from the body of the patient. Photo depicting a Heimlich valve. The construction of the flutter valve enables it to function as a one-way valve allowing airflow, or the flow of a fluid, in only one direction along the drainage tube.
In 1962, Heimlich invented the chest drainage flutter valve (also called the Heimlich valve), [11] [12] and was granted a patent for the device in 1969. [13] He said his inspiration came from seeing a Chinese soldier die from a bullet wound to the chest during World War II , a claim that was disputed by Frederick Webster, Heimlich's medical ...
The free end of the tube is usually attached to an underwater seal, below the level of the chest. This allows the air or fluid to escape from the pleural space, and prevents anything returning to the chest. Alternatively, the tube can be attached to a flutter valve. This allows patients with pneumothorax to remain more mobile. [20]
Flow divider valve: a valve providing a plurality of output flows from a single fluid source [2] Flutter (Heimlich) valve: a specific one-way valve used on the end of chest drain tubes to treat a pneumothorax; Foot valve: a check valve on the foot of a suction line to prevent backflow
Ventricular flutter is an arrhythmia, more specifically a tachycardia affecting the ventricles with a rate over 250-350 beats/min, and one of the most indiscernible. It is characterized on the ECG by a sinusoidal waveform without clear definition of the QRS and T waves.
Atrial flutter (AFL) is a common ... and the tricuspid valve. [1] Type I flutter is further divided into two subtypes, known as counterclockwise atrial flutter and ...
"Heart flutter", an abnormally rapid heartbeat: Atrial flutter, a common abnormal heart rhythm; Ventricular flutter, a tachycardia affecting the ventricles with a rate over 250-350 beats/min; Flutter valve, a one-way valve used in respiratory medicine to prevent air from travelling back along a chest tube
Some chest drains may utilize a flutter valve to prevent retrograde flow, but those that do not have physical valves employ a water trap seal design, often aided by continuous suction from a wall suction or a portable vacuum pump.
