My university leaves me alone about my unit because it isn't a traditional unit and doesn't require service/calibration unless we've noticed a problem.ģ. It is a pain to send off these units which are essential to lab progress once a year to get them serviced and calibrated. Also, now not a problem with our annual safety evaluation since we don't have compressed cylinders.Ģ. This is nice as inevitably someone in lab fails to let others know that we're almost out. Sharpe, PhD - University of Oklahoma Health Sciences Center - College of Pharmacy Oklahoma, OKġ. ![]() No hot spots like you see with traditional warming pads.įIR warming increases body metabolism, thereby discharging anesthetics and toxins, which aid in faster recovery from surgery.Īmanda L. Your animal can now be warmed over an extended period of time without having to constantly increase the temperature. FIR allows researchers to safely warm animals for a longer period of time without unknowingly overheating the animal. ![]() Less mouse warming is required with FIR than with conventional techniques. Studies have shown that FIR can maintain therapeutic temperatures longer when compared with conventional heating methods. The body can absorb as much as 90% of FIR heat compared to only 20% with conventional warming pads. The energy level of water in the body's cells is gently increased through “resonant absorption” warming the inside of the body. FIR waves resonate with organic matter and penetrate deep into the body. FIR is totally safe in fact, 80% of the sun’s rays are in the low energy, far infrared range. FIR light warms the body without warming the air between the FIR source and the body. Far infrared light is absorbed by cells deep within the body of the animal which safely raise the core body temperature. MouseSTAT Jr.The pads warm the animal through far infrared (FIR) warming. The higher force spring in the sensor clips may cause ischemia in the sensing area from the continuous squeezing pressure.įinally, other pulse oximetry systems also require a dedicated external PC to operate, which takes up valuable lab bench and surgical area space. Placing the sensor in these locations typically requires the extra effort of shaving the area. Therefore, the adapted human pulse oximeter sensors from other manufacturers need to use thick sections of the small laboratory animal body that approximate a human finger, such as the neck or thigh. When the human-sized sensors are attempted to be used on a translucent small laboratory animal paw, there is too much light delivered, which overflows the large light sensor. Since only a small amount of light passes through a finger, a large sensor is required to attempt to collect as much of the minute amount of transmitted light as possible. The large LEDs flood a boney appendage such as a finger with a tremendous amount of light, which is mostly absorbed or blocked by the bones and connective tissue. These adapted human-sized sensors have large LEDs and light sensors that were designed to work on a human index finger or other like appendages. Other small laboratory animal pulse oximeters use human-size sensors mechanically adapted for small animals. Please feel free to contact one of our product specialists to discuss your specific application. *Respiratory rate accuracy may be influenced be your study protocol. We also offer a selection of MRI compatible sensors to choose from. This can be a mouse paw, but more commonly is a rat paw, rabbit ear or small animal tongue. It can be used on any animal and on any appendage with sufficient vascularization and irrigation. ![]() ![]() The larger MouseSTAT Sensor for larger animals (SPO2-LG) is ideal for penetrating thicker tissue, such as that on a rat or larger animal. They use a miniature LED and light sensor to transmit and receive the red and infrared light that are proportional to the size and translucence of the small laboratory paw. The MouseSTAT Paw Sensors for mice and rats (SPO2-MSE and SPO2-RAT) were specifically designed for small laboratory animals.
