Oxygen Delivery Device Lookup

Humidify above 4 L/min; check nares and the skin behind the ears for breakdown. Patient can eat and talk.

Never run below 5 L/min — exhaled CO₂ accumulates in the mask. Remove for meals (switch to cannula per order).

Reservoir bag should deflate no more than one-third on inspiration — increase flow if it collapses.

The emergency mask — keep the bag inflated and one-way valves intact. A patient on an NRB needs close monitoring and usually an escalation plan.

Delivers an exact FiO₂ regardless of breathing pattern — the device of choice when CO₂ retention makes precision matter (COPD).

Heated and humidified; provides some PEEP-like effect and washes out dead-space CO₂. Watch for worsening work of breathing — the next step is often NIV or intubation.

Loose-fitting — useful with facial trauma, burns, or claustrophobia. FiO₂ is unpredictable.

Always humidify — the upper airway that warms and moistens air is bypassed. Drain condensation away from the patient.

Attaches directly to an ET or trach tube — common during ventilator weaning trials. Watch for fatigue and rising respiratory rate.

Resuscitation device — ensure a tight seal (two-person technique when possible) and watch chest rise.
