✨️✨️Portacath✨️✨️
A portacath provides continuous access to a large vein in the body, usually the
superior vena cava (SVC). A port is implanted beneath the skin. A catheter runs
from the port to the SVC.

Knowing the pulse locations in the body is important for assessing overall cardiovascular health, effectively responding during medical emergencies, and monitoring blood flow to specific limbs!

Left Side Heart Failure — and how it sets off a chain reaction that affects not just the heart, but also the lungs and kidneys. 💛

Let’s start at the top: the left ventricle, your heart’s main pumping chamber. In a healthy heart, it contracts powerfully to send oxygen-rich blood into the aorta and out to the body. But when disease strikes — such as myocardial infarction (heart attack) or chronic hypertension — the ventricle begins to change.

There are two main types of left heart failure:
1️⃣ Systolic dysfunction – The ventricle becomes dilated and weak. The muscle fibers stretch too much (eccentric hypertrophy), so it can’t contract effectively. Blood pools inside, leading to low cardiac output — meaning your tissues don’t get enough oxygen.
2️⃣ Diastolic dysfunction – The ventricle wall thickens (concentric hypertrophy) due to long-term pressure overload, such as from hypertension or aortic stenosis. It becomes stiff and can’t relax properly, resulting in poor filling during diastole.

Now here’s where things get dangerous 👇
When the left side fails, blood backs up into the lungs, increasing pulmonary pressure. This leads to pulmonary congestion and shortness of breath — a hallmark of left-sided heart failure. If pressure keeps building, it starts to strain the right side of the heart too, leading to biventricular failure.

The effects ripple down to the kidneys, too. 🧠➡️❤️➡️🫁➡️🧠
Because of the reduced cardiac output, the kidneys receive less blood flow. In response, they activate vasoconstriction and fluid retention mechanisms (like the RAAS system), which unfortunately make things worse — increasing blood pressure and fluid overload. The result? Impaired filtration function, swelling, and worsening heart failure.

💡 Key takeaway: Left heart failure isn’t just a heart problem — it’s a whole-body crisis. It affects your lungs, increases venous pressure, and limits kidney function. Early management of hypertension, coronary artery disease, and lifestyle modification can stop this deadly domino effect before it starts.
