Below is a detailed step-by-step guide on how to handle bleeding based on severity and location. General Steps for Managing Any Type of Bleeding Ensure Safety – Wear gloves if […]

First Aid for an Obstructive Sleep Apnea (OSA) Emergency What is Obstructive Sleep Apnea (OSA)? Obstructive Sleep Apnea (OSA) happens when the airway partially or completely collapses during sleep, causing breathing to stop for several seconds to minutes. Most people with OSA experience brief pauses in breathing multiple times per night, but a severe OSA […]

First Aid for Croup (Common in Children) – Emergency Response What is Croup? Croup is a respiratory infection that causes swelling in the airways, making it hard for a child to breathe. It is most common in children under 5 years old and usually caused by a virus. A child with croup has a distinctive […]

Rescue breathing is needed for drowning victims who are not breathing adequately or have stopped breathing entirely. Here’s when and how it’s applied: When Rescue Breathing Is Needed: No Breathing or Agonal Breaths: If the victim is unresponsive and not breathing or only gasping (agonal breathing), start rescue breathing immediately. Before Starting Chest Compressions: For […]

Rescue breathing can still be effective in a drowning victim, even if their lungs contain water, because only a small amount of water typically enters the lungs during drowning. Here’s how rescue breathing works in this situation: 1. Clearing the Airway: Before giving rescue breaths, check for and remove any visible obstructions in the victim’s […]

The appendix is a small, finger-shaped pouch attached to the large intestine, located in the lower right side of the abdomen. For many years, it was considered a vestigial organ with no significant function, but research suggests it may play a role in the immune system and gut health. Here’s what we currently understand about […]

The spleen is an important organ in the immune and circulatory systems, located in the upper left side of the abdomen, just under the rib cage. While it is not essential for survival (other organs can compensate for its loss), it plays several critical roles in maintaining health. Here’s what the spleen does: 1. Filters […]

The liver is a vital organ with a wide range of essential functions that keep the body healthy. It is the largest internal organ and sits in the upper right side of the abdomen, beneath the rib cage. Here’s what the liver does: 1. Detoxification: The liver filters and removes toxins, drugs, alcohol, and harmful […]

The prostate is a small, walnut-shaped gland in males located just below the bladder and in front of the rectum. It is part of the male reproductive system and plays a crucial role in fertility. Here’s what it does: 1. Produces Seminal Fluid: The primary function of the prostate is to produce a fluid that, […]

Brain death is the complete and irreversible loss of all brain function, including the activity of the brainstem, which controls vital involuntary functions such as breathing, heartbeat regulation, and reflexes like pupil response to light. When brain death occurs, the brain no longer sends signals to the body, and the individual is legally and medically […]

Electrolytes play a crucial role in hydration because they help your body maintain fluid balance, support cellular function, and optimize the absorption of water. Here’s how they differ from water in contributing to hydration: 1. Maintaining Fluid Balance Electrolytes (e.g., sodium, potassium, calcium, magnesium) regulate the movement of water in and out of cells through […]

Bloodborne pathogens (BBPs) are microorganisms present in blood and other bodily fluids that can cause diseases when transmitted to another person. These pathogens include viruses, bacteria, and parasites. Below are the most common diseases associated with bloodborne pathogens: Viral Infections Hepatitis B (HBV) Affects the liver and can lead to chronic liver disease, cirrhosis, and […]

The idea that “sugar feeds cancer” is based on the observation that cancer cells consume glucose (a type of sugar) at a much higher rate than normal cells. Here’s how and why this happens: 1. High Glucose Consumption by Cancer Cells Warburg Effect: Cancer cells preferentially use a metabolic process called aerobic glycolysis, even in […]

ATP (Adenosine Triphosphate) is a molecule that serves as the primary energy carrier in all living organisms. It is often referred to as the “energy currency” of the cell because it provides the energy needed for various biological processes. Structure of ATP: ATP is a nucleotide composed of three main parts: Adenine: A nitrogenous base. […]

Parts of the body that lack access to oxygenated blood may not respond to the nervous system because oxygen is essential for the proper functioning of cells, including neurons (nerve cells) and muscle cells. Here’s why this happens: 1. Oxygen’s Role in Cellular Function: Oxygen is necessary for cellular respiration, the process by which cells […]

The brainstem is a critical part of the brain responsible for controlling many vital and automatic functions necessary for survival. It connects the brain to the spinal cord and acts as a relay center for information between the brain and the body. Here’s what the brainstem controls: 1. Autonomic Functions: The brainstem regulates basic, involuntary […]
