Daugherty, A., Rateri, D., Hong, L., Balakrishnan, A. Measuring Blood Pressure in Mice using Volume Pressure Recording, a Tail-cuff Method. J. Vis. Exp. (27), e1291, doi:10.3791/1291 (2009).
코다 8 채널 높은 처리량 비침습 혈압 시스템은 동시에 8 쥐 또는 쥐에 혈압을 측정합니다. 코다 꼬리 즉석 시스템은 꼬리 혈액 볼륨을 결정하여 혈압을 측정하는 볼륨 압력 녹음 (VPR)를 사용합니다. 개별 펄스 신호를 얻기 위해 필요없이 특별히 고안된 차동 압력 변환기 및 폐색 꼬리 즉석 측정 꼬리의 총 혈액 볼륨. 특별한주의는 가장 정확한 혈압 수치를 도출하기 위해 폐색의 즉석의 길이에 여유입니다. VPR 쉽게 같은 C57BL6 생쥐로 어두운 피부 설치류에 판독을 구하고 호환 MRI입니다 수 있습니다. 코다 시스템은 여섯 (6) 다른 혈압 파라미터 측정을 제공, 수축기 및 diastolic 혈압, 심장 박동은, 혈압, 꼬리 혈액 흐름, 그리고 꼬리 혈액 볼륨을 의미합니다. 성능은 깨어 또는 anesthetized 마우스 또는 쥐 중 하나를 만들 수 있습니다. 코다 시스템은 컨트롤러, 노트북 컴퓨터, 소프트웨어, 수갑, 동물 소유자, 적외선 온난 패드, 그리고 적외선 온도계를 포함합니다. 900g 크기로 쥐에 8g만큼 작은 생쥐를위한 7 개의 홀더 크기가 있습니다.

We have used the Kent and Visitech machines. The bottomline is that no system is perfect and they are highly operator dependent. We have found the Kent machines require more training (for humans and mice!) but the data is more better quality and more similar to telemetry.

1) We do stroke surgery. Can we measure the blood pressure continuosly during 1 hour surgery.If not can we measure blood pressure at different time point during the surgery.If i have to measure blood pressure at different time point during the surgery, then do i have to set up the cuff placement on the base of the tail again everytime.
2)In the protocol, occlusion cuff has to placed as close to the base of the tail as possible.During the mice stroke surgery, we insert the rectal probe into the anus. would the placement of the occlusion cuff interfere with the placement of the rectal probe into the anus. we would not use the animal holder because our animals are anesthesized for the stroke surgery.

1)What is the purpose of thermal regulation of the animal?During the stroke surgery, our animals are maintianed at 37 celsius. In our case, do we need to thermoregulate the animals at 32 celsius for measuring blood pressure.Will the maintainance of body temperature at 37 cel interfere the accuracy of the measurement of blood pressure.

Good Day sir/mam,
We are having our research problem about the feasibility of okra extract as therapy to hypertension. and our experimental subject is mice. therefore,i would like to ask if where can we avail this equipment in the Philippines? thank you for more suggestions just contact me at this email dvanirish@yahoo.com thank you.!

I am a pharmacy student one of University in Indonesia.
I'm doing research studies (to pass on degree) about antihypertensive using CODA system.
I've followed the procedure properly.
But, why the time reading in this experiment always shows fail tail volume?
Thank you for more suggestions please contact me at this email nadyanovyani@gmail.com.
Thanks a lot..

I am a pharmacy student from Padjadjaran University in Indonesia.
I'm doing research studies (to pass on degree) about antihypertensive using CODA system. the first time I used this device, it could work very well. the device could read the blood pressure and said "OK". but after a couple of days, it couldn't work very well. everytime I used this device, it always said "fail tail volume" even though I have followed the procedure properly and the rats I used in this experiment are in good condition (no smell and no noise). So, I would like to ask you how to solve this problem.This is the first time our faculty use this device and I would really appreciate it if you could give me the reply as soon as possible. Thanking you in advance.
Sincerenly
Nadya
