Application of New Lineage Tracing Techniques in Cardiovascular ...
2024年2月15日 · We provide detailed examples of how new genetic lineage tracing tools based on orthogonal recombinases circumvent previous technical limitations and address the conundrums in the cardiovascular field.
Normal arterial line waveforms - Deranged Physiology
2015年6月29日 · According to textbooks, the arterial pulse wave does not appear on the monitors until a 160-180 millisecond delay. Most of these timing recordings are made in the cardiac cath lab, using transducer-tipped catheters in the aortic root.
Diagnostic approach for myocardial contusion: a retrospective ...
Myocardial contusion describes a condition of bruising or (microscopically small) hemorrhaging of the heart muscle caused by blunt thoracic trauma. In patients who have sustained blunt thoracic trauma, the prevalence of myocardial contusion ranges from 0 to 76%, depending on the diagnostic criteria used [1 – 10].
Interpretation of abnormal arterial line waveforms - Deranged …
2015年6月29日 · Though the scanned copy of their 1978 article is greatly degraded by time, one can use the tracing they produced to identify the cardinal features. The ventricle struggles to squeeze blood though the stenosed aortic valve, and thus the systolic upstroke becomes less steep. No matter the force of contraction, the pressure rise will not be rapid.
Examples of arterial line tracing before and after AO, with ROSC ...
Light-grey hatched markings represent non-physiologic arterial line tracings/artifact. Dotted line with AO next to it represents aortic occlusion time. [...] Purpose: Aortic occlusion (AO)...
Arterial Line Sources of Error - Periop Concepts
2024年5月9日 · We rely on an accurate invasive blood pressure to ensure our patient is safe, so if you see a problem with your arterial line trace: 🔺 Trace quality (steep rise, curved peak, dicrotic notch) 🔺 Numbers don’t look right. Then use our “TRUE BP” framework to troubleshoot the problem: 👉🏻 Tighten connections.

2024年11月16日 · arterial waveform morphology varies with site of measurement as a result of the physical characteristics of the vascular tree (impedance and harmonic resonance)
"Arterial Lines in Cardiac Arrest" By Dr. Weingart From …
2023年10月28日 · In this episode, Dr. Scott Weingart discusses the role of arterial lines in the management of cardiac arrest patients. He explains the importance of continuous blood pressure monitoring and how arterial lines can provide more accurate and reliable blood pressure readings than non-invasive methods.
Mechanical Cardiac Circulatory Support: an Overview of the …
2021年10月1日 · Alternatively, if the patient has an arterial line, its waveform may be utilized to trigger the balloon pump. In case of loss of pulsatility, such as during CPR, the IABP can be switched to an internal waveform trigger.
Techniques of arterial access - ScienceDirect
2004年1月1日 · Arterial lines may also aid in the assessment of cardiac contractility by examination of the shape of the waveform and upstroke of the tracing, or as a requisite portion of some techniques for the minimally invasive assessment of cardiac output.
