Pet Blood Pressure Measurement Methods: The Application and Operation Steps of Doppler Blood Pressure Monitors
Measuring pet blood pressure is crucial for understanding an animal's health. It can help us detect heart disease, kidney disease, and other health problems early and take appropriate treatment measures in time. Doppler blood pressure monitors, due to their ease of operation, affordability, and relatively accurate measurement results, have become the most commonly used method for pet blood pressure measurement. This article will detail the application of Doppler blood pressure monitors in pet blood pressure measurement and the measurement process.
I. Animal Blood Pressure Measurement Methods
Animal blood pressure measurement methods are mainly divided into invasive and non-invasive methods. Invasive methods involve surgically implanting a blood pressure monitor into a blood vessel after the animal has been anesthetized. The values obtained are relatively accurate. However, because it requires anesthetizing the animal, it is not practical for clinical use.
Among non-invasive blood pressure monitors, Doppler blood pressure monitors are widely used in pet blood pressure measurement due to their simple operation, affordability, and accurate readings. Before measuring blood pressure, the animal should be calmed and allowed to familiarize itself with the environment before measurement. Before drawing conclusions about high pressure, the possibility of false positive results due to clinical anxiety in the animal should be ruled out.
II. Application of Doppler Blood Pressure Monitors
Doppler blood pressure monitors have a wide range of applications in pet healthcare, mainly in the following areas:
1. Selection tool for echocardiography: Blood pressure and heart sounds auscultation can be included in routine health checks. Blood pressure represents the pressure of blood pumped by the heart against the walls of the blood vessels. If the blood pressure measured by a Doppler blood pressure monitor is high and heart sounds auscultation is abnormal, this may indicate a serious cardiovascular condition in the animal, requiring echocardiography or regular follow-up.
2. Tracking the use of antihypertensive drugs: When an animal suffers from heart disease or hypertension, blood pressure should be re-measured three days after taking antihypertensive drugs to determine whether blood pressure has returned to normal or to control the dosage of the drugs according to blood pressure values. If blood pressure is normal, blood pressure should be re-measured 3-7 days later to track blood pressure changes. Subsequently, blood pressure should be re-measured at least every 3-6 months.
3. Pre-operative assessment: Before surgery in animals, blood pressure should be measured. If blood pressure is low and albumin is low, surgery should not be performed. Forcing surgery could lead to shock in the animal during surgery, which would be difficult to rescue. During surgery, the systolic pressure should ideally be maintained at 80-100 mmHg to ensure adequate blood perfusion to body tissues. Blood pressure should also be measured after surgery to prevent low blood pressure, which could lead to insufficient blood supply to the heart and kidneys, resulting in tissue hypoxia, decreased resistance, and increased susceptibility to infection.
4. Emergency rescue: During emergency rescue in cases of shock or respiratory arrest in animals, Doppler blood pressure monitors can be used to measure blood flow, which can indicate pulse and blood flow, providing a reference for emergency rescue.
III. Measurement Process with Doppler Blood Pressure Monitors
1. Blood pressure monitor cuff and placement
The blood pressure monitor cuff is filled with an airbag and comes in various sizes. The length of the cuff airbag must exceed 60% of the circumference it wraps around, and the width must be 40-50% of the circumference it wraps around. The cuff should not be too long or too narrow. If the cuff is too short, it will bounce off when glued on and blood pressure cannot be measured. If the cuff is too narrow, it will create excessive pressure and lead to high blood pressure readings. In general, the cuff should be placed between the elbow joint and wrist joint, avoiding bony protrusions.
2. Doppler blood pressure monitor probe
The core component of the Doppler blood pressure monitor is the probe. The probe is placed under the cuff and emits or receives sound waves from the blood vessel wall to measure blood flow in the artery. The frequency change converts the frequency into an audio signal. The probe placement area requires shaving and the use of ultrasound coupling gel to minimize the impact of air between the probe and the placement area. The probe is generally fixed with tape to prevent interference from movement during placement.
3. Doppler blood pressure monitor control buttons
The Doppler blood pressure monitor control buttons are used for listening to sounds, adjusting sound volume, controlling switches, etc.
4. Handle and display
The handle is used to control the inflation of the airbag, and the display shows the blood pressure values. After inflation, press the button to deflate the airbag.
5. Measurement process
Before measuring blood pressure, the animal should be allowed to familiarize itself with the environment and be calmed down. The first time an animal's blood pressure is measured, it may be more sensitive. The first reading can be disregarded, and the measurement can be repeated after the animal has adapted. To minimize errors, at least five measurements should be taken, and the average value should be used as the final reference value.
IV. Precautions
1. Before measurement, ensure that the animal is in a calm state and avoid excessive tension or excitement in the animal, which may affect the measurement results.
2. During the measurement process, carefully observe the animal's reaction. If the animal exhibits discomfort, stop the measurement immediately.
3. After the measurement, clean the measurement area promptly to maintain cleanliness and hygiene.
4. Calibrate the Doppler blood pressure monitor regularly to ensure accurate and reliable measurement results.
Summary of Experience
Doppler blood pressure monitors are a simple and easy-to-use tool that can help us understand our pet's health in a timely manner. When using Doppler blood pressure monitors for measurement, pay attention to calming the animal, ensuring that it is in a calm state, and taking at least five measurements to average as a reference value. Regular blood pressure measurement in pets can help us detect diseases early and take timely treatment measures to improve pet health.
