Oxygen Toxicity (11)

causes of oxygen toxicity

• high oxygen concentrations

• long duration of oxygen therapy

• severity of lung disease

common signs/symptoms of oxygen toxicity

• nonproductive cough

• substernal chest pain

• nausea/vomiting

• nasal stuffiness

• fatigue

• headache

• sore throat

how to prevent oxygen toxicity

give the lowest oxygen level needed to get the desired effect

• minimum o₂ for maximum benefit

nursing interventions to reduce oxygen toxicity risk

• use the lowest o₂ possible

• monitor abg

• decrease oxygen as soon as the condition improves

for patients on supplemental oxygen, what must the order include?

rate, delivery mode, and target saturation range

bedside assessments to perform while a patient is on oxygen

• respiratory rate

• skin color

• dyspnea

• use of accessory muscles,

• pulse ox

what hygiene care should we give to patients on supplemental oxygen?

oral and nasal care

how to prevent device related injuries

cushion the body parts touching devices

what should we be doing often when in the room with a patient on supplemental oxygen ?

checking the flow meter

who develops oxygen-induced hypoventilation

clients with copd and chronic hypoxemia/hypercarbia

who has hypoxic drive?

COPD patients

hypoxic drive

when you’re desensitized to CO2 stimulant to breathe

why do we give patients with hypoxic drive less O2?

high o₂ can reduce or eliminate their hypoxic drive to breathe

• they might stop breathing

nursing interventions for oxygen-induced hypoventilation

• monitor respiratory rate, ABG, and SPO₂

• provide the lowest o₂ level

• if possible, give o₂ via a venti mask

why is a venturi mask suggested in oxygen-induced hypoventilation risk?

it delivers a precise oxygen concentration, helping avoid excess o₂ in patients who need tight control (e.g., copd)
