Flashcards
Simple Face Mask
Simple Face Mask
Delivers low-flow oxygen at 28-50% concentration at 5-10 LPM, suitable for mild to moderate respiratory distress.
Partial Rebreather Mask
Partial Rebreather Mask
Delivers a higher oxygen concentration, 40-70% at 5-15 LPM, addressing conditions like hypoxia and shock.
Non-Rebreather Mask
Non-Rebreather Mask
Delivers a high oxygen concentration, almost 80-100% at 12-15 LPM, for patients breathing unassisted but needing maximum oxygen support.

Study Notes
- There are multiple types of masks to deliver added oxygen to a patient
- Each deliver a different concentration of oxygen
Simple Face Mask
- Delivers low-flow continuous oxygen
- Delivers oxygen at a concentration of 28-50%
- Flow rate of 5-10 LPM (liters per minute)
- It is indicated for mild to moderate respiratory distress
- It has a metal piece to conform to the nose shape
- Exhalation ports are included as well as a strap
Partial Rebreather Mask
- Delivers higher concentrations of oxygen than a simple mask
- Partial rebreather delivers oxygen up to a concentration of 40-70%
- Flow rate of 5-15 LPM
- Indications include Hypoxia, Respiratory disease, Cardiac disease, Shock, Trauma, Severe blood loss and Seizures
Non-Rebreather Mask
- Used to deliver high concentration of oxygen without dilution from exhaled or atmospheric air
- Delivers close to 80-100% oxygen concentration
- Flow rate of 12-15 LPM
- Only used in patients who can breathe on their own as those who require assistance should receive mechanical ventilation
- Indications include severe physical trauma, carbon monoxide poisoning, smoke inhalation and chronic airway obstruction
Venturi Mask
- Air-entrainment mask that delivers fixed oxygen concentrations
- Delivers 24-50% oxygen concentration
- Appropriate for patients who have a hypoxic drive to breathe, but also need supplemental oxygen
- Used for patients with chronic obstructive pulmonary disease (COPD)
- Prevents O2 toxicity for patients with chronic respiratory diseases
Tracheostomy O2 Mask
- Type of mask to deliver added oxygen to a patient through a tracheostomy
