- Complications of Mechanical Ventilation ()
Introduction Barotrauma is damage to body tissue secondary to pressure difference in enclosed cavities within the body. Barotrauma is commonly observed in scuba divers, free-divers, or even in airplane passengers during ascent and descent. The most common organs affected by barotrauma are the middle ear (otic barotrauma), sinuses (sinus barotrauma), and the lungs (pulmonary barotrauma). Pulmonary barotrauma […]
- The Bag Valve Mask ()
Introduction Bag valve mask ventilation is a skill of utmost important for emergency providers. It is not easy and requires practice to master as it will be utilized in emergent settings. Proper patient positioning is critical to the procedure. The tongue often falls to the back of the pharynx which can occlude the airway. The […]
- PETCo2 = Capnometry ()
Capnometry is a non‐invasive monitoring technique which allows fast and reliable insight into ventilation, circulation, and metabolism. In the prehospital setting it is mainly used to confirm correct tracheal tube placement. In addition it is a useful indicator of efficient ongoing cardiopulmonary resuscitation due to its correlation with cardiac output, and successful resuscitation. It helps […]
- Artificial Ventilation ()
Introduction Positive pressure ventilation is a form of respiratory therapy that involves the delivery of air or a mixture of oxygen combined with other gases by positive pressure into the lungs. As gas enters the lungs, the interalveolar pressure increases until a change in flow or pressure are detected by the machine delivering the mixture, […]
- Ventilation Of Protected Airways ()
At some point during the resuscitation, an advanced provider such as a Paramedic or AEMT will place an advanced airway into the patient’s airway. This measure is useful in that it resolves the problem of gastric distention, but it creates another problem: hyperventilation. The increased respiratory cycles will drop a patient’s blood pressure like a […]
- Automatic Transport Ventilator/Resuscitator ()
Transport ventilators, also known as portable ventilators, are mechanical ventilation devices designed specifically for emergency or transport scenarios. Like stationary ventilators, they help patients breathe by delivering either oxygen-enriched gas or room air into a patient’s respiratory system through invasive or noninvasive means. Rescuers around the world still reach for a bag valve mask (BVM) to manually ventilate a […]
- Manually Triggered Ventilation Device ()
Everybody Needs One Of These In Their Truck A flow-restricted, oxygen-powered ventilation device (FROPVD), also referred to as a manually triggered ventilation device (MTV), is used to assist ventilation in apneic or hypoventilating patients, although these devices can also be used to provide supplemental oxygen to breathing patients. It can be used on patients with […]
- Assisting Ventilation ()
The Patient Imagine if you will a patient with difficulty breathing is laying on the stretcher in the back of the ambulance. Their shortness of breath is turning into an inability to speak and the patient has a scared look in their eyes that tells you that they need serious help. The medics can see […]
- What The MOI Means To The Primary Survey ()
EMS personnel should always be on the lookout for a mechanism of injury (MOI). The MOI is force that results in injury to the patient. Injuries are easy to see (if you look for them). Obviously, not all MOI’s are equal. A person that tripped on a rug in the living room probably won’t have […]
- Normal Ventilation vs Positive Pressure Ventilation ()
Air movement In normal ventilation, the lungs are stretched out by the ribs and diaphragm. This creates a vacuum resulting in air filling up the pharynx and filling the lungs with air. In positive pressure ventilation, air is pushed into the patient’s pharynx with great pressure. The air fills the dead space of the airway […]
