A patient may die when an oxygen mask is removed if they have a critical underlying condition, such as severe respiratory failure or chronic obstructive pulmonary disease (COPD), that requires supplemental oxygen to maintain adequate blood oxygen levels. Without the mask, their oxygen saturation can drop rapidly, leading to hypoxia, organ failure, and potentially death. Additionally, if the patient is unable to breathe effectively on their own, the sudden removal of oxygen support can be life-threatening. Immediate medical intervention is essential in such situations.
The oxygen mask is typically used with either an oxygen tank or a wall-mounted oxygen supply in medical settings to deliver oxygen to individuals who are experiencing respiratory distress or low oxygen levels. The mask is connected to the oxygen source via tubing to provide a controlled flow of oxygen to the patient.
A bag valve mask is a bag used to resuscitate a patient by supplying air or oxygen directly into the trachea and into the lungs.

Oxygen is delivered directly to the patient through oxygen therapy devices such as nasal cannulas, oxygen masks, and oxygen tanks. These devices provide a controlled flow of concentrated oxygen for the patient to breathe in, helping to increase the oxygen levels in their blood.
There are two ways to give oxygen to a patient. You can deliver it through a face mask, connected to a tank of oxygen, or you can place the patient in a room which has its own pure oxygen atmosphere, often at high pressure as well. High pressure (technically called hyperbaric) oxygen will enter the blood even if the patient is not breathing.
Using a non-rebreathing oxygen mask at under 10 lpm of oxygen flow can cause carbon dioxide to build up and be re-inhaled by the patient.
non-re-breather mask
A non-rebreather mask can deliver 60-80% oxygen when used with a flow rate of 10-15 liters per minute. This high concentration is achieved because the mask has a reservoir bag that fills with oxygen to ensure a constant supply of oxygen to the patient.
A Venturi mask is used to deliver a precise concentration of oxygen to patients. To use it, first select the appropriate color-coded adapter to set the desired oxygen flow rate (usually between 2 to 15 liters per minute). Attach the adapter to the mask and connect it to the oxygen source. Ensure a snug fit on the patient's face for effective delivery, and monitor the patient's oxygen saturation levels regularly.
A non-rebreather mask increases SpO2 by delivering a high concentration of oxygen directly to the patient. It features a reservoir bag that fills with oxygen, allowing the patient to inhale a mixture that is approximately 90-100% oxygen while preventing room air from entering. The one-way valves on the mask prevent exhaled air from re-entering the bag, ensuring that the patient receives a consistent supply of oxygen. This effective delivery system enhances oxygen saturation levels in the blood, making it particularly useful in emergencies.
The lowest flow rate typically used for a simple oxygen mask is around 5 liters per minute. This flow rate helps ensure that the mask is delivering a sufficient amount of oxygen to the patient while also preventing carbon dioxide buildup within the mask.
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.
