Determine the % of O2 being delivered via nasal cannula based upon liter flow rate
The percentage of O2 being delivered via a nasal cannula based on the liter flow rate would be approximately 27-29%
The nasal cannula delivers ambient air mixed with supplemental oxygen, and the percentage of O2 being provided can be estimated by the oxygen flow rate. To calculate the percentage of O2 delivered, start with a baseline of 21% (the oxygen concentration in the air) and add an additional 3-4% for every liter of oxygen flow per minute. For example, if you have a flow rate of 2 liters per minute (L/min), the percentage of O2 being delivered would be approximately 27-29% (21% + 2 × 3-4%). This formula assumes that the patient is taking regular breaths and has a proper seal on the nasal cannula.
Keep in mind that these estimations can vary based on individual factors, such as patient breathing patterns and the fit of the nasal cannula. Additionally, the liter flow rate should be adjusted according to the patient's needs and medical condition to ensure appropriate oxygenation. Consult a healthcare professional to determine the optimal flow rate and O2 delivery for a specific patient. The percentage of O2 being delivered via a nasal cannula based on the liter flow rate would be approximately 27-29%.

why does coarctation of the aorta present with rib notching?
Coarctation of the aorta is a congenital heart defect where there is a narrowing or constriction in the aorta, which is the main artery that carries blood from the heart to the rest of the body.
The narrowing occurs just after the branching of the arteries that supply blood to the upper body. As a result, the blood flow to the lower body is reduced, causing high blood pressure in the upper body and low blood pressure in the lower body.
Over time, the body tries to compensate for the reduced blood flow by developing collateral blood vessels around the area of the coarctation. These collateral vessels are small, fragile vessels that grow between the ribs to try and supply blood to the lower body. As these vessels grow, they can cause notches or grooves in the ribs, which is known as rib notching.
Rib notching is a characteristic sign of coarctation of the aorta and is caused by the collateral vessels that grow to compensate for the narrowed aorta. The notches are usually seen on the underside of the ribs and are more common on the left side of the body. Rib notching is a useful diagnostic tool for identifying coarctation of the aorta, particularly in infants and children, as it can be seen on a chest X-ray.
Coarctation of the aorta presents with rib notching because:
Coarctation is a narrowing of the aorta, the main blood vessel that supplies oxygen-rich blood to the body. Due to this narrowing, blood flow is restricted, and the body compensates by increasing pressure in the arteries before the coarctation site. This causes collateral circulation, which means that the blood finds alternative routes to reach the lower body.
One of these routes is through the intercostal arteries, which run under the ribs. As the blood flow through these arteries increases, they enlarge and erode the underside of the ribs, causing the characteristic rib notching seen in coarctation of the aorta.

Venous irritation associated with the injection of diazepam and lorazepam is secondary to:
the high degree of water solubility of these agents
the presence of propylene glycol as a solvent
the presence of metabisulfite as a preservative
the low pH of these agents
Venous irritation associated with the injection of diazepam and lorazepam is secondary to the presence of propylene glycol as a solvent.
Diazepam and lorazepam are both benzodiazepines that are commonly used to treat anxiety, seizures, and muscle spasms. These medications are often administered intravenously in clinical settings, but they can cause venous irritation and inflammation at the site of injection.
The cause of this irritation is due to the presence of propylene glycol, which is a common solvent used in the formulation of diazepam and lorazepam injectable solutions. Propylene glycol can be a strong irritant to the venous endothelium, which is the inner lining of the blood vessels.
When propylene glycol-containing solutions are injected into the veins, they can cause local inflammation and damage to the endothelial cells. This can lead to swelling, redness, and pain at the site of injection.
In severe cases, propylene glycol can even cause thrombosis, or the formation of blood clots within the veins.
To prevent venous irritation and inflammation associated with the injection of diazepam and lorazepam, it is important to use proper injection techniques and to dilute the medication with saline or other compatible fluids. In some cases, alternative medications may be used that do not contain propylene glycol as a solvent.

A 24-year-old female is scheduled for resection of a cerebral aneurysm. She has no other significant past medical history. Acceptable levels of hypotension would include a mean arterial pressure of:
20 - 30 mm Hg
35 - 45 mm Hg
50 - 60 mm Hg
90 - 100 mm Hg
None of the listed ranges of mean arterial pressure are acceptable for a patient undergoing cerebral aneurysm resection.
Hypotension during surgery can lead to reduced cerebral blood flow and increased risk of stroke, while hypertension can increase the risk of bleeding from the aneurysm.
Maintaining adequate cerebral perfusion pressure (CPP) is critical during the surgery to prevent neurological complications.
CPP is calculated as the difference between mean arterial pressure (MAP) and intracranial pressure (ICP), with a normal range of 60-80 mm Hg.
Therefore, the goal during cerebral aneurysm resection is to maintain a stable MAP within a narrow range around the patient's baseline level, typically within 10-20% of their normal range.
This can vary based on the individual patient's characteristics and the surgeon's preference.
In general, it is recommended to avoid hypotension during cerebral aneurysm resection, as it can lead to decreased CPP and potentially cause ischemic injury to the brain.
The acceptable range of MAP during surgery would depend on the individual patient and the surgeon's preference, but generally, a MAP of 70-90 mm Hg is commonly used to maintain adequate CPP.
Therefore, it is important for the anesthesia team to carefully monitor the patient's blood pressure and adjust medication doses as needed to maintain a stable MAP during the procedure.
The specific target range should be discussed with the surgeon and anesthesia team prior to the surgery.
