Perme Lecture 5+6 Flashcards
With higher flow rate devices, you need increased ______
Humidification
If flow rate is more than 3L/m -> needs humidification
Nasal canula can give up to 6L/m what can happen if it is increased more than this?
Potentially damages nose
What kind of mask can deliver the HIGHEST concentration of oxygen
Note: very serious if patient has this!
Nonrebreather mask
What is the advantage of a venturi mask?
Can choose the oxygen percentage delivered based on colored valve
For nonrebreather masks, the flow rate needs to be….
High enough to keep the back 1/3 to 1/2 full
A __________ mask is typically the last step after intubating OR the first step after a patient got off intubation
nonrebreather mask
A patient will have a tracheostomy mask (T-collar) if they need….
Prolonged mechanical ventilation
What is paradoxiccal breathing
More accessory muscles working/ diaphragm is tired
These patients must be mechanically ventilated
What are 4 mechanical ventilation indications
- Acute respiratory failure
- protection of airway and lung parenchyma
- Relief of upper airway obstructions
- Improvement of pulmonary toilet (basically improved ability to clear secretions)
Before you work with an intubated patient what should you do?
Have nurse or doctor certify that the intubation is in the right location
What are the 5 most important things to look at on a ventilator display
Mode of ventilation
FiO2
PEEP
Minute Ventilation
Respiratory Rate
EACH PARAMETER TELLS YOU ABOUT YOUR PATIENTS LAST BREATH
What is PEEP
Positive end expiratory pressure
pressure applied by ventilator at the end of each breahte
prevents airway from collapsing
Excessive PEEP may cause….
Reduced cardiac output
Impair oxygen delivery system
_____ helps expand collapsed alveoli
PEEP
What is considered normal PEEP? Moderate PEEP? high PEEP?
3-5 is normal physiological PEEP
Moderate 5-15
High > 15
Note: High PEEP is used only for severe lung injury
