Numbers you need to remember for diagnosing pulmonary artery hypertension (PAH) 🧵

• mPAP > 25 mm Hg
• PCWP/PAOP < 15 mm Hg
• TPG > 12 mm Hg
• TRV > 3.0 m/sec
• TAPSE < 16 mm
• Woods unit > 3 (mPAP - PCWP/CO)
• CT angio chest : PA size > 29 mm

#Cardio #PulmCrit Image mPAP is mean pulmonary arterial pressure which can only be accurately measured by right heart catheterization

Pressures more than 25 mm Hg, means there is clinically/hemodynamically significant resistence at the level of pulmonary arterioles/capillaries

What is meant my Pulsus Paradoxus ?
A one-stop pathophysiology thread you’d ever need 🧵

#MedTwitter #MedStudentTwitter #MedEd #FOAMed #CardioEd #USMLE #ICU #EMTwitter Image To understand Pulsus Paradoxus in detail,

It is essential to realise for a fact that, 1. Pleural pressure, 2. Abdominal pressure, 3. Heart chamber pressures & 4. Lung pressures, are all interconnected, interact & react among each other.

A thread on mechanics, logistics and reasons behind positive end expiratory pressure (PEEP) significance while handling patients on mechanical or non-invasive ventilation 🧵

#MedTwitter #EDTweeter #PulmTwitter @PulmPEEPs Image PEEP is the air pressure that stays “WITHIN” the lungs after a person finishes exhaling. Now, this PEEP pressure is always greater than atmospheric pressure. It essentially prevents the alveoli’s to collapse and maintains the airways open.

Progesterone challenge test for secondary amenorrhea.

Core points 🧵🪡

#obgyntwitter #MedTwitter While assessing 2ndary Amenorrhea ⏬

Give progesterone > bleeds | It was the one lacking on board (anovulation/PCOS)

Give progesterone > doesnt bleed | try adding estrogen & simulate a menstrual cycle >> If then Bleeds🩸> something’s wrong with the FSH/LH fine tuning

AV dissociation, capture beats and fusion beats are all hallmarks of ventricular tachycardia

A simple understanding 👇

#CardioTwitter #Cardiology #Medtwitter What’s a “capture beat” ?

During ventricular tachycardia, sometimes the SA nodal firing takes control of independent ventricular depolarization for brief moment, as this happens, “CAPTURE BEATS” appear. They are nothing but a brief moment of normal looking P-QRS pattern Image
