What is the goal of respiratory therapy
in respiratory failure?
- Maintain adequate oxygenation and
ventilation
- Correct acid-base imbalance
What oxygen therapy basics are
important in respiratory failure?
- administer O2 at lowest FiO2 to keep
SpO2 and PaO2 at patient specific
goals

1

,- ALWAYS start on 2L/NC
What is the goal of oxygen therapy in
respiratory failure?
Maintain PaO2 at 55 to 60 mmHg or
more and SaO2 at 90% or more at the
lowest O2 concentration possible
What can occur when a patient
receives a high FiO2 for prolonged
periods?
Adverse effects
What are adverse effects of high FiO2
for prolonged periods?
- Oxygen toxicity (greater than 60% O2
for greater than 48 hours)
- Absorption atelectasis
- Increased pulmonary capillary
permeability




2

,- Decreased surfactant production or
inactivation
- Fibrotic changes in the alveoli
What is the oxygen therapy for COPD
patients, what triggers their hypoxic
drive, and what is considered if they
have an inadequate response to
therapy?
- High CO2 levels do not act as
respiratory stimulant (low hypoxic
drive)
- their trigger is low O2 levels!!
- Provide O2 at low flow (1-2L) with
venturi mask
- Consider mechanical ventilation with
inadequate response
What are respiratory therapy nursing
implementations for respiratory
failure?

- Patient positioning
- Effective coughing
- Chest physiotherapy
- Suctioning
- Humidification
- Hydration

respiratory therapy for respiratory
failure?
