A striking example of perfusion effects can be demonstrated by com- promise of circulation to the arm. A complete or partial occlusion of the artery in the upper arm will result in an immediate drop in hand tem- perature, and detectable in less than 30 seconds from the time of oc- clusion. The rapid response and the simplicity of infrared measure- ments make the technique effective in the hospital environment.

III. Clinical Applications

The following is a brief synopsis of a number of clinical applications for surface temperature measurements. These subjects are not covered in sufficient detail to be used for clinical protocols and are intended to be general indications for the use of infrared temperature measure- ments for clinical purposes. Because of the sensitivity of surface temperatures to the environment, it is important that certain precau- tions be followed in making surface temperature measurements. They are:

1.Provide for adequate equilibration time in the room environment at which the measurements will take place.

2.Protect the patient from drafts and exposure to cold surfaces (win- dows in winter).

3.Consider the use of a skin surface marker to ensure the measure- ment sites are repeatable.

Regional Blocks

The effectiveness of regional blocks can be monitored using the change in surface temperature due to sympathetic vasodilation of the tissue in the blocked area, eliminating the subjective pin prick assessment method. Depending on the type and location of the block, one can expect to see a temperature increase in the order of 1 to 1.5°C on the skin surface of the blocked area in 10 to 30 minutes after the injection of the blockade drug.

Using the DermaTemp to verify the

geography of the block

In a recent study on sympathetic blockade, Chamberlain et al (1986)1 measured the dynamic pattern of skin changes during spinal anesthe

DT 1001-LN, DT 1001-RS, DT 1001, DT 1001-LT specifications

The Exergen DT 1001 series, consisting of the DT 1001-LN, DT 1001, DT 1001-RS, and DT 1001-LT, represents a cutting-edge advancement in non-invasive infrared thermometry technology. These models are designed for accurate and reliable temperature measurement across various settings, making them invaluable tools for healthcare professionals, educators, and individuals monitoring their own health.

A standout feature of the Exergen DT 1001 series is its precision in measuring core body temperature. Utilizing patented infrared technology, these devices detect the thermal radiation emitted by the temporal artery, thus providing an accurate representation of internal body temperature. This non-invasive method is not only safe but also quick, as it can yield results within seconds, making it ideal for both clinical environments and home use.

The DT 1001 series emphasizes ease of use. Equipped with a simple one-button operation, even individuals without technical training can operate the device effectively. The easy-to-read digital display provides clear temperature readings, which can often be coupled with visual and auditory alerts for fever detection, enhancing user experience.

Further enhancing user convenience is the memory function of the DT 1001 series. These models can store multiple readings, allowing users to track temperature trends over time. This feature is particularly useful in monitoring patients with fevers or chronic health issues where regular temperature checks are necessary.

The DT 1001-LN and DT 1001-LT are distinguished by their lightweight and portable design, making them suitable for on-the-go temperature checks. Conversely, the DT 1001-RS is optimized for clinical settings, featuring enhanced durability and robust performance under frequent usage.

Each model has been rigorously validated to meet clinical standards, ensuring that healthcare practitioners can rely on their accuracy. With their advanced technology, user-friendly design, and versatility, the Exergen DT 1001 series stands out as a leading choice in the realm of non-contact thermometers, promoting effective health monitoring for a wide range of users. Their continued popularity highlights a significant trend in modern healthcare towards efficient, precise, and non-invasive diagnostic tools.
