Transient symptomatic hypotension occurs commonly (up to 70%) both in association with regular medication and in the absence of constant hypertension management. Thus, medication used in therapy is a highly unlikely cause for hypotension.
Hypotension is a decrease in systemic blood pressure below accepted low values. While there is not an accepted standard hypotensive value, pressures less than 90/60 are recognized as hypotensive. Hypotension is a relatively benign condition that is under-recognized mainly because it is typically asymptomatic.
Transient hypotension is a temporary drop in blood pressure that can cause dizziness, fainting, and other symptoms. While typically not a cause for alarm, understanding the underlying factors that lead to transient hypotension is essential for managing and preventing episodes.
Low blood pressure is a condition in which the force of the blood pushing against the artery walls is too low. It's also called hypotension. Blood pressure is measured in millimeters of mercury (mm Hg). In general, low blood pressure is a reading lower than 90/60 mm Hg.
Orthostatic hypotension is defined as a decrease in blood pressure of 20 mm Hg or more systolic or 10 mm Hg or more diastolic within three minutes of standing from the supine position or on...
The 2011 guidelines on the definition of OH, neurally mediated syncope, and postural tachycardia, which were updated by a multidisciplinary panel of experts, have established a standard definition of OH.
So your patient said they were hypotensive but now their bp is fine. What are you supposed to do now? Do you just anchor on his or her bp meds as the cause of the hypotension? In this EMEd lecture we review a systematic approach for these patients.
Hypotension has two definitions: Absolute hypotension: Your resting blood pressure is below 90/60 millimeters of mercury (mm Hg). Orthostatic hypotension: Your blood pressure stays low for longer than three minutes after you stand up from a sitting position.
Use this equation to think through the differential diagnosis of hypotension: MAP - mean arterial pressure; SVR - systemic vascular resistance - HR, heart rate; SV - stroke volume. History and physical exam (especially volume status) are the most important initial steps to narrowing down the diagnosis and determining initial treatment.
Hypotension occurs when the cardiac output decreases and/or the systemic vascular resistance decreases. Hypotension is usually due to: Decreased effective circulating volume (hypovolemia)
