Air embolism is a rare, but potentially fatal, event that occurs when a bolus of air enters the vascular space. There are two types of air embolism – venous and arterial. To really understand this concept, you need to have a good understanding of cardiopulmonary circulation. So let’s review that pathway.  Deoxygenated blood comes from venous circulation throughout the body and enters the right atrium. From there it flows into the right ventricle and out through the pulmonary artery into pulmonary circulation. This is where gas exchange takes place. The red blood cells offload CO2 and pick ..read more

Local anesthetics are medications that block nerve impulses so that pain signals aren’t transmitted to the brain. The result is that the anesthetized area is numb and pain is controlled.  Just because local anesthetics are “local” doesn’t mean systemic toxicity can’t occur. Local anesthetic systemic toxicity (LAST) occurs when local anesthetics extend into the system at toxic levels. It most typically occurs due to the physician accidentally injecting the medication into the intravascular space. However, it can also be from locally administered overdose, which leads to systemic toxicity ..read more

When the heart rate is irregular or too slow, cardiac output is compromised. A pacemaker may be utilized to support the heart’s electrical system, stabilize arrhythmias, and ensure the heart pumps at a rate that supports tissue perfusion throughout the body.  A pacemaker may be indicated in patients with arrhythmias such as sick sinus syndrome (also known as sinus node dysfunction), symptomatic bradycardia, or high-grade heart blocks. Other indications include post myocardial infarction, heart failure, congenital heart defects, and temporarily after some cardiac surgeries. This episode a ..read more

What is a pacemaker?  When the heart rate is irregular or too slow, cardiac output is compromised. A pacemaker may be utilized to support the heart’s electrical system, stabilize arrhythmias, and ensure the heart pumps at a rate that supports tissue perfusion throughout the body. While there are different types of pacemakers, they all have a pulse generator and electrodes. The pulse generator provides electrical impulses, which are transmitted through the electrodes, causing cardiac muscle to contract. Once the pacemaker is placed it is programmed to set the rate and other parameters. Wha ..read more

A helpful way to establish priorities is to classify them as urgent, intermediate and low priority ..read more
