ASD

atrial

[a´tre-al] pertaining to an atrium.atrial natriuretic factor (ANF) a hormone produced in the cardiac atrium; it inhibits renin secretion and thus the production of angiotensin, and stimulates aldosterone release. Its effect is increased excretion of water and sodium and a lowering of blood pressure, which reduces the workload of the heart.atrial septal defect a congenital heart defect in which the ostium primum or ostium secundum, openings in the septum primum of the embryonic heart, fail to close completely after birth. When an opening remains between the atria, some of the oxygen-rich blood from the left atrium passes into the right atrium and travels back to the lungs without being first transported through the body.

Atrial septal defect. The shunt is from left atrium to right atrium. From Betz et al., 1994.

defect

[de´fekt] an imperfection, failure, or absence.congenital heart defect see congenital heart defect.aortic septal defect see aortic septal defect.atrial septal defect see atrial septal defect.filling defect an interruption in the contour of the inner surface of stomach or intestine revealed by radiography, indicating excess tissue or substance on or in the wall of the organ.neural tube defect see neural tube defect.septal defect a defect in the cardiac septum resulting in an abnormal communication between opposite chambers of the heart. Common types are aortic septal defect, atrial septal defect, and ventricular septal defect. See also congenital heart defect.

BAG MASK DEVICE

bag mask device

A manually operated resuscitator used to ventilate a nonbreathing patient or assist the ventilation of a patient who is not breathing at an effective rate or tidal volume. The device consists of a bag, an oxygen reservoir system, a one-way flow valve, and a clear face mask. It is designed to be attached to an oxygen source by tubing to deliver concentrations approaching 100%. See: illustration

belay device

A device using friction to brake or slow the movement of a rope, or to protect a patient, basket, climber, or other rescuer.

A mechanical device used to engorge and stimulate the clitoris. It is used as a U.S. FDA–approved treatment for female sexual dysfunction.

electronic infusion device

Abbreviation: EID
A device for monitoring intravenous infusions. The device may have an alarm in case the flow is restricted because of an occlusion of the line. In that case, the alarm will sound when a preset pressure limit is sensed. The device can also signal that an infusion is close to completion. The pressure is regulated by the height at which the container is positioned above the level of the heart when the patient is lying flat. A height of 36 in (91 cm) provides a pressure of 1.3 lb/sq in (70 mm Hg). Most EIDs are equipped to stop the flow of the infused liquid if accidental free flow occurs. See: infusion pump

esophageal intubation detector device

A syringe attached to the endotracheal tube immediately after an intubation attempt.

Patient care

If aspiration is difficult or stomach contents are withdrawn, or both, the endotracheal (ET) tube may have been placed in the esophagus and needs to be removed and reinserted. If aspiration is easy and free of stomach contents, it is probable that the ET tube is located in the trachea; the rescuer should then confirm tube placement by other techniques, e.g., a combination of auscultation, x-ray, and pulse oximetry.

femoral compression device

A device used to apply pressure to the large artery or vein in the thigh after it has been cannulated in order to reduce bleeding from the punctured vessel. Femoral compression devices are used, e.g., after angiography.

Abbreviation: LVAD
A pump surgically implanted in patients with severe heart failure to move blood from the left ventricle to the ascending aorta. The LVAD usually augments the heart's function until it heals (following a severe myocardial infarction) or until a heart transplant becomes available, e.g., for patients with heart failure with a markedly diminished ejection fraction. The LVAD also may be used permanently for a patient who does not meet criteria for transplantation.

listening device

A speech amplifier that aids the hearing-impaired in direct person-to-person communication or telephone conversation. Such devices differ from conventional hearing aids in that they reduce interference from background noises.

oxygen-conserving device

Abbreviation: OCR
Any device that reduces the loss of administered oxygen into the environment, e.g., one that releases oxygen to a patient only when the patient inhales.

oxygen-powered ventilation device

A multifunction ventilation devicehat uses high-flow oxygen. This device can often be triggered by negative pressure caused by an inhaling patient; it can also be operated by a button while the operator watches the patient's chest rise.

CAUTION!

During resuscitation, it is necessary to use the positive-pressure aspect of this device and manually trigger or compress the button because the patient cannot open the valve by inhaling. These devices should be fitted with an overinflation high-pressure alarm to avoid gastric distention and/or barotrauma.

personal flotation device

Abbreviation: PFD
A life vest to prevent drowning and near drowning. People engaged in water sports, such as boating or water skiing, or rescuers working on or near the water should wear PFDs at all times. The U.S. Coast Guard sets standards and establishes specifications for the manufacture and use of PFDs. Personal flotation devices may be used to provide added buoyancy for the patient during aquatic therapy.

personal assistive mobility device

Personal mobility device.

personal mobility device

Any assistive device that facilitates individual human transportation. Examples include powered wheelchairs, scooters, bicycles and unicycles. Although many such devices are used by people with activity or mobility restrictions, mobility aids can be employed generally, e.g., for urban transportation in place of automobiles. Synonym: personal assistive mobility device

pointing device

A type of input device for sending commands to a computer. Moving the device results in movement of a cursor on the monitor or computer screen. Pointing devices range from the conventional desktop mouse, trackball, and touch-sensitive screens to infrared and ultrasound pointers mounted on the head. See: light pointer; switch

pubovaginal device

A device fitted for use in the vagina to help prevent urinary incontinence. See: pessary

sequential compression device

Abbreviation: SCD.
A device to reduce edema or prevent the formation of blod clots in an extremity. A chambered nylon sleeve is progressively inflated from its distal segment to the proximal segment, forcing venous and lymphatic return.

Patient discussion about ASD

Q. In the future will he with ASD ever be able to live independently? I have a friend who is staying as a paying guest and is being taken care of by all our family members. In the future will he with ASD ever be able to live independently?A. I am very much moved by your deeds.
• Many people with autism do flourish and go on to hold responsible jobs and live independently. Others have the intellectual abilities to be employed but are held back by their inability to adapt socially to the stresses of everyday life.
• The focus of every intervention program for the person with autism should be to work on helping them adapt to living in society. Their quality of life and ability to function is far more important than how they do on an I.Q. test.
