Abstract:
In order to provide correct care for newborns it is necessary to determine the arterial pressure, since it is an important physiological indicator of body vitality. We measured blood pressure in 50 healthy, full term infants, born in Zagreb. All blood pressure readings were done by using a Doppler ultrasound. The 4 cm width cuff was used. The mean systolic pressure was 78.76 mmHg (SD +/- 8.6) and the diastolic one 35.78 mmHg (SD +/- 6). The level of systolic pressure was associated with body-mass (r = 0.371; p < 0.01), while sex had no effect on it.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
Assessment of blood pressure in brachial artery(one-step method)
Prepare for the Procedure:
Assessing Blood pressure using a doppler ultrasound
Pre-Procedural Guidelines for Doppler Ultrasound Blood Pressure Assessment:
Preparation of Equipment:
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
