The venturi mask, also known as an air-entrainment mask, is a medical device to deliver a known oxygen concentration to patients on controlled oxygen therapy. Venturi masks are considered high-flow oxygen therapy devices. This is because venturi masks are able to provide total inspiratory flow at a specified FIO2 to patients therapy. The kits usually include multiple jets in order to set the desired FIO2 which are usually color coded. The color of the device reflects the delivered oxygen concentration, for example: blue = 24%; yellow = 28%; white = 31%; green = 35%; pink = 40%; orange = 50%. The color however varies with different brands and the user must check the instructions to determine the correct color for the desired FIO2.
partial rebreather mask with attached with 1L reservoir bag that saves 1/3 of exhaled air, while rest gets out via ports covered with one-way valve. This allows patient to rebreathe some of the carbon dioxide, which acts as stimulator of breathing.
A nasal cannula is typically provided instead of a rebreather face mask when a patient requires lower levels of supplemental oxygen, generally in situations of mild to moderate hypoxemia or for long-term use. It allows for more patient comfort and mobility, as it does not cover the entire face. Additionally, a nasal cannula is preferred when the patient is able to breathe comfortably on their own and does not require a high concentration of oxygen. In cases where high flow oxygen is necessary, a rebreather mask would be more appropriate.
To set up a partial rebreather mask, first ensure that the mask is clean and free from defects. Connect the mask to an oxygen supply source, typically via a flowmeter, and set the oxygen flow rate to the prescribed level (usually between 6 to 10 liters per minute). Position the mask over the patient's nose and mouth, adjusting the straps for a snug fit to minimize leaks. Finally, check the reservoir bag to ensure it is inflated before use, indicating proper oxygen flow.
The oxygen flow rate for a partial rebreather mask typically ranges from 8-15 liters per minute. This ensures an adequate supply of oxygen for the patient while allowing for some exhaled air to be rebreathed. The specific flow rate may vary depending on the patient's condition and needs.
A nonrebreather mask (NRB) should have an oxygen flow rate of at least 10 liters per minute in order to deliver the maximum oxygen concentration.
The acronym NRB stands for "Non-rebreather mask". These are used in medical emergencies where the patient requires urgent oxygen therapy, as the mask allows higher concentrations of oxygen to enter the body.
You get the rebreather in Nellis Air Force Base and you can use it to breathe underwater. You can either gather supplies to make it or with a certain science level you can skip this step entirely.
There are numerous barriers; some more effective and safe than others. Short answer is 3 types; a mask, a non-rebreather mask, and a BVM. The older microshield and other types without a 1-way valve should no longer be used. At least, you want a CPR mask that has a 1-way valve. The next better would be the CPR mask with the O2 connection (and1-way valve). As you get more into the clinical setting, a non-rebreather and BVM would be the other types.
A non-rebreather mask typically delivers oxygen at a flow rate of 10 to 15 liters per minute. This high flow rate ensures that the patient receives nearly 100% oxygen, as the mask has a reservoir bag that fills with oxygen, allowing for minimal room air to mix in. It is crucial for treating patients with severe respiratory distress or hypoxemia.
As long as the patient needs it to improve oxygenation. The liter flow can be increased to 15L/min with a non-rebreather but if that's not sufficient the patient may need a cpap or bipap machine or even possible intubation.
A non-rebreather mask is generally not recommended for COPD patients due to the risk of delivering excessively high levels of oxygen, which can lead to respiratory distress or hypercapnia. COPD patients often rely on hypoxic drive for their breathing, so maintaining a careful balance of oxygen therapy is crucial. Instead, low-flow oxygen via a nasal cannula or a Venturi mask is usually preferred to ensure adequate oxygenation without the risk of suppressing their respiratory drive. Always consult with a healthcare professional for individualized treatment.
Do not change any of the CPR steps for a quad patient. Having supplemental oxygen, using a BVM, or non-rebreather mask would be helpful.
