The jaw-thrust maneuver is an effective airway technique, particularly in patients in whom cervical spine injury is a concern. The jaw thrust is a technique used on patients with a suspected or possible cervical spinal cord injury and is used on a supine patient. The practitioner uses their index and middle fingers to physically pull the ...
Airway clearance therapy is treatment that uses a number of airway clearance techniques to clear the respiratory airways of mucus and other secretions. [1] Several respiratory diseases cause the normal mucociliary clearance mechanism to become impaired resulting in a build-up of mucus which obstructs breathing, and also affects the cough reflex.
The pitot tube can be inserted through a small hole in the duct with the pitot connected to a U-tube water gauge or some other differential pressure gauge for determining the flow velocity inside the ducted wind tunnel. One use of this technique is to determine the volume of air that is being delivered to a conditioned space.
The pitot tube may become blocked, because of insects, dirt or failure to remove the pitot cover. A blockage will prevent ram air from entering the system. If the pitot opening is blocked, but the drain hole is open, the system pressure will drop to ambient pressure, and the ASI pointer will drop to a zero reading. If both the opening and drain ...
The active cycle of breathing techniques (ACBT) is a flexible regimen comprising breathing control, thoracic expansion exercises and the FET, frequently combined with gravity-assisted positioning. Increasing lung volumes during thoracic expansion allows air to get behind distal secretions via collateral ventilatory channels.
In the three-hole kind of instrument, there are two yaw direction tubes which are chamfered and silver soldered symmetrically on the two sides of a pitot tube. It is otherwise similar to the other kinds of yawmeters. In the four- and five-hole configurations, the central pitot tube is surrounded by three or four chamfered tubes, respectively.
Hypoventilation training is a physical training method in which periods of exercise with reduced breathing frequency are interspersed with periods with normal breathing.The hypoventilation technique consists of short breath holdings and can be performed in different types of exercise: running, cycling, swimming, rowing, skating, etc.
A Pitot tube measures the difference between the static pressure and the flowing pressure of the media in the pipe. The volumetric flow is calculated from that difference using Bernoulli's principle , taking into account the pipe's inside diameter. [ 2 ]
