1. Animal blood pressure measurement methods
There are two types of animal blood pressure measurement: invasive and non-invasive. The non-invasive method is to measure the blood pressure through surgery after the animal is anesthetized. The meter is implanted in blood vessels and the measured values are relatively accurate. However, because animals need to be anesthetized, it is not very practical in clinical use. Among non-intrusive blood pressure monitors, Doppler blood pressure monitors are widely used because of their simplicity, accurate values, and reasonable price. Before measuring blood pressure, animals should be stimulated to familiarize themselves with the environment before measuring blood pressure. Before making a determination of high blood pressure, it is necessary to eliminate the possibility of false positive results due to clinical anxiety of the animal.
2. Application of Doppler sphygmomanometer
1. Doppler sphygmomanometer can be used as a selection tool for cardiac ultrasound, and blood pressure and heart sound auscultation can be Participating in routine health check-up items, blood pressure represents the pressure value of the blood pumped by the heart against the inner wall of the blood vessels. If the blood pressure value measured using a Doppler sphygmomanometer is high and the heart sound auscultation is abnormal, it indicates serious cardiovascular disease. It is necessary to arrange a cardiac ultrasound examination or regular follow-up.
2. Tracking the use of antihypertensive drugs
When an animal has heart disease or high blood pressure, the blood pressure should be measured again three days after taking the drug to determine whether the blood pressure has returned to normal or not. Patients use blood pressure values to control drug dosage. If blood pressure is normal, blood pressure should be measured again at 3-7 dawn to track, and blood pressure should be measured again at least 3-6 months later.
3. Evaluation before surgery
Measurement of animal blood pressure before surgery. If the blood pressure and albumin before surgery are low, surgery is not suitable. It is not easy to save memories after shock. During the operation, the interruption pressure is best maintained at 80-100mg to maintain sufficient blood perfusion in the body tissue. It is also necessary to measure the animal's blood pressure after surgery to prevent the blood pressure from being too low and insufficient blood supply to the heart and kidneys, resulting in tissue hypoxia and reduced resistance that may easily lead to discomfort.
4. Rescue
When animals suffer from shock or respiratory arrest, Doppler blood pressure measurement can be used to measure blood fluctuations during the rescue process, and the pulse and blood fluctuations can be understood.
3. Measurement process of Doppler blood pressure monitor
Waiting for measurement Blood pressure animals
1. Sphygmomanometer sleeve wearing and storage position
The blood pressure monitor sleeve wears an inflated air bag. total specifications.
The length of the cuff balloon of the blood pressure monitor must exceed 60% of its surrounding circumference, and the width must be 40-50% of its surrounding circumference, and cannot be too long. , and it should not be too wide. If it is too short, the air bag will pop up after sticking and the blood pressure cannot be measured. If it is too narrow, the pressure will be too high and the measured blood pressure will be too high. Under normal circumstances, the sleeve is located between the elbow joint and the wrist joint to avoid the bone overhang.
Doppler sphygmomanometer probe.
The center of the Doppler blood pressure monitor. The probe is placed under the cuff. The probe measures the blood flow in the artery by emitting or transmitting sound waves received from the blood vessel wall. Through the change of frequency, the probe converts the frequency into a sound signal. The place where the probe is placed needs to be shaved, and ultrasonic coupling agent needs to be used to reduce the effect of the air between the probe and the place where it is placed. The probe can generally be stuck with adhesive tape to avoid disturbance caused by moving back and forth.
The control button of the Doppler sphygmomanometer can hear the sound, adjust the sound volume, control opening and closing, etc. .
Handle, instrument panel, negative air bag inflation, The final blood pressure value is reflected in the value on the instrument panel. After inflating, press the button to deflate the airbag.
Another Maltese dog, measuring blood pressure.
The dog was quite agitated when measuring blood pressure, which led to poor control during the blood pressure measurement process, but resulted in incorrect measurement. Animals whose blood pressure has not been measured for the first time are more sensitive. You may not use the first data and measure it after it is consistent. In order to reduce errors, it should be measured at least five times to take the equilibrium value as the final reference value.
