KOSMOS provides the following sweep speeds: 20 mm/sec, 25 mm/sec, 35
mm/sec, and 50 mm/sec.
• When calculating heart rate, KOSMOS is capable of rejecting tall T-waves (as
false QRS peaks) up to amplitudes that are up to 75% of QRS amplitude.
Ergonomics
KOSMOS is intended for quick-look applications by qualified health
professionals. It is not intended for continual use in radiology or other
departments. If you need to use the device for a continual period, take the
following precautions:
•
Position yourself comfortably, either with a chair with appropriate lower-back
support or by sitting or standing upright.
•
Minimize twisting, relax your shoulders, and support your arm with a
cushion.
•
Hold Kosmos Torso lightly, keep your wrist straight, and minimize the
pressure applied to the patient.
Repetitive ultrasound scanning may cause occasional discomfort in your
thumbs, fingers, hands, arms, shoulders, eyes, neck, back, or other parts
of your body. However, if you experience symptoms such as constant or
recurring discomfort, soreness, pain, throbbing, aching, tingling,
numbness, stiffness, burning sensation, muscle fatigue/weakness, or
limited range of motion, do not ignore these warning signs. Promptly see
a qualified health professional. Symptoms such as these can be linked
with Work Related Musculoskeletal Disorders (WRMSDs). WRMSDs can be
painful and may result in potentially disabling injuries to the nerves,
muscles, tendons, or other parts of the body. Examples of WRMSDs
include bursitis, tendonitis, tenosynovitis, carpal tunnel syndrome, and
De Quervain syndrome.
While researchers are not able to definitively answer many questions
about WRMSDs, there is a general agreement that certain factors are
associated with their occurrence, including preexisting medical and
physical conditions, overall health, equipment, and body position while
performing work, frequency of work, and duration of work.
