How much oxygen does Hudson mask give?

The simple mask or the medium concentration Hudson mask 6 to 10 liters per minute, and you’re giving 35% to 55%. A non-rebreather mask is between 50% and 90%.

How does Hudson mask work?

The mask has a one-way valve system that prevents exhaled oxygen from mixing with the oxygen in the reservoir bag. When you inhale, you breathe in oxygen from the reservoir bag. Exhaled air escapes through vents in the side of the mask and goes back into the atmosphere.

How many liters of oxygen can be given through mask?

The simple face mask can deliver higher flow rates than nasal cannula (6–10 liters per minute) for an FiO2 of 40–60% oxygen. Nasal cannula and simple face masks are described as low flow delivery systems.

What’s the flow rate of the Hudson oxygen mask?

Hudson mask Delivers 30-40%. Flow rate 5-10L/min. Step up from nasal cannula but doesn’t deliver specific % of oxygen like venturi. Venturi (air entrapment) mask Delivers 24-60%. Flow rate (oxygen flow rate is set on the O 2 wall tap. It is shown on mask along with the % O 2 delivery). Often used in COPD. Types:  BLUE = 2-4L/min = 24% O 2

When to use an oxygen mask in a hospital?

These are the most commonly used masks in a ward setting when patients are awake and alert. However, there are other methods to deliver oxygen, especially if the patient is under anaesthesia (example: during surgery) or if the patient is unresponsive (example: during a CPR).

When to use a venturi mask for oxygen therapy?

Do not use a Normal Face Mask with less than 5L/min flow rate, as your patient may ‘rebreathe’ carbon dioxide, which can lead to hypercapnia (high carbon dioxide levels in the body) and even acid-base imbalance. 3. Venturi Mask Venturi masks are ideal if you want to measure the oxygen delivery accurately.

What are the oxygen delivery characteristics of the Hudson oxy-one?

The tightly fitting mask demonstrated an orderly reduction in FIO2 as ventilation increased and oxygen flow rate to the mask decreased. The mean FIO2 at a ventilation of 4.5 l.min-1 and 8 l.min-1 oxygen flow was 78% and this fell to 27% at a ventilation of 16 l.min-1 and oxygen flow of 2 l.min-1.
