Mentioned it in the video. Pulmonary pressure is when blood is freely flowing through the pulmonary circuit. Wedge pressure when the flow is obstructed.

@@alexsheremett3097 Well it means, the concept needs to be revisited. We are not looking for the pressure BEFORE the wedge. We are looking for the pressure BEYOND the wedge. Coz, that’s where lies the left atrium. And this whole exercise is to measure the pressure in the LA.

Thank you Sir I have two questions 1) Is PCWP also a measure of LVEDP ? 2) Why PCWP falls in ARDS ?
@VivekSirsPhysiology
9 ай бұрын
PCWP primarily measures the LA pressure. However, a rise in LVEDP will also increase the LA pressure (due to congestion), and consequently will show up in PCWP. ARDS will compress the pulmonary vessels. Blood flow to LA will decrease. LA pressure will decrease, hence, PCWP will decrease (remember, it’s NOT the pulmonary capillary pressure; it’s the LA pressure.)

thank you professor ! I have a question though (which may be a little ignorant), when measuring PCWP, why is the pressure in left atrium not inferior since its a chamber of a bigger volume compared to the pulmonary capillaries ? (there is more free space, so wouldn't it be more low pressure ?)
@VivekSirsPhysiology
5 ай бұрын
Hello. Yes, that’s the case normally. And hence the blood flows from the pulmonary capillaries to the left atrium (high to low pressure). In measuring of PCWP though, we are creating a wedge and stopping the blood flow. From the point of the wedge up to left atrium, there is no flow for some time. Since no flow, there is no drop of pressure. From the point of wedge to LA, it becomes an equilibrated system or chamber (for a while), with entire distance having the SAME pressure. So, if we measure the pressure just beyond the wedge, it gives us the LA pressure.

@@ishasharma6079 if surfactant is removed, in all probability, water might get filled into alveoli. Surfactant is partly responsible for keeping the alveoli dry. Now, if alveoli are filled with water, the hysteresis will decrease. The pressure-volume relation will become quite linear, and will follow similar path in inspiration and expiration.

sir can you please explain again pul cap wedge pressue if there is no flow then how there is no pressure drop/ change / difference because if there is no flow then there would be fall in presure and sir can you please explain what is pulmonary end diastolic pressure
@VivekSirsPhysiology
Жыл бұрын
Flow, whenever it occurs, is due to the pressure difference. Now imagine that we have created a wedge. The blood flow reaching the wedge can not cross the wedge. All its kinetic energy is dissipated. So whatever pressure was there in the pulmonary vessels, it will be before the wedge. Beyond, there is a continuous path without any flow. So, left atrial pressure will be the pressure in that entire path, beyond the wedge.

Current trends (in Physiology) are - Lifestyle intervention, sports medicine, yoga, aviation physiology. It depends on availability of resources. For example, if a gym is available nearby, or some sports academy, then the topic can be - “Effects of various nutritional supplements on the muscle mass and endurance”. If yoga center is available, then - “effects on pranayam breathing or nostril breathing on neurophysiological parameters”. If hospital is available nearby then - “effects of lifestyle intervention on various lifestyle diseases (like dose reduction, subjective improvement, etc)”
