Peripheral pULSe Assessment and Arterial pRessure (PULSAR) (PULSAR)
Association Between Palpable Peripheral Pulses and Arterial Blood Pressure in Patients With Circulatory Shock: An International Prospective Multicenter Observational Cohort Study
This prospective multicenter observational study aims to investigate the relationship between palpable peripheral pulses and simultaneously measured arterial blood pressure in adult patients with circulatory shock or impending circulatory failure. Peripheral pulse palpation is routinely used in emergency medicine, trauma care, critical care, and cardiopulmonary resuscitation as a rapid clinical assessment of circulation. However, the association between palpable pulses and actual arterial blood pressure remains poorly validated.
Patients treated in emergency departments, intensive care units, operating rooms, and other acute care settings will undergo routine pulse palpation at predefined anatomical locations including carotid, femoral, and radial arteries. Simultaneously measured non-invasive and/or invasive arterial blood pressure values will be recorded from routine clinical monitoring systems. Additional clinical variables relevant to circulatory status will also be collected.
The study seeks to define blood pressure thresholds associated with pulse palpability and evaluate the agreement between invasive and non-invasive blood pressure measurements in patients with circulatory shock.
調査の概要
詳細な説明
The presence or absence of palpable peripheral pulses is widely used as a rapid bedside indicator of circulatory status during trauma care, emergency medicine, intensive care, and cardiopulmonary resuscitation. Advanced Trauma Life Support (ATLS) teaching traditionally assumes that palpable pulses at different anatomical sites correspond to specific systolic blood pressure thresholds. However, these assumptions are based on limited evidence from small observational studies.
This international multicenter prospective observational cohort study aims to investigate the relationship between palpable carotid, femoral, and radial pulses and simultaneously measured arterial blood pressure in adult patients with circulatory shock or impending circulatory failure.
Patients receiving routine hemodynamic monitoring with non-invasive blood pressure (NIBP) and/or invasive arterial blood pressure (IBP) monitoring will be included. Pulse palpation will be performed during routine clinical care without altering treatment or management.
The primary objective is to determine the association between pulse palpability and measured systolic blood pressure. Secondary objectives include identifying blood pressure thresholds associated with pulse palpability, evaluating agreement between invasive and non-invasive blood pressure measurements, and assessing whether patient factors such as vascular disease or vasoactive medication use influence pulse palpability.
