What is some home care considerations for suctioning a ETT or tracheostomy

encourage client to cough to clear airways first
instruct how to determine if suctioning is needed
instruct proper process for suctioning
stress the importance of adequate hydration bx it thins out secretions

reservior nasal cannulas also called oxymizer oxygen conserving devices

What are some home care considerations for suctioning

to clean– suction boiling water then suction air until the tube is dry
if cleaned this way, catheters can be reused up to 24hrs
teach to wash hands to prevent infection

they have a greater risk for infections

What is a special consideration for a partial rebreather mask and nonrebreather masks

the reservoir bag attached cannot deflate completely during inpiration

What are some techniques to decrease the risk of developing suction complications

suction only when needed
use sterile technique
dont use saline instillations
use hyperinflation and hyperventilation before and after suctioning
use hyperoxygenation

What are some lifespan considerations for suctioning a ETT or tracheostomy for older adult

oral antiseptic rinses reduce the rate of infection

perform thorough lung assessment before and after to determine the effectiveness of the suctioning

Why is 2L of O2 per NC usually the max delivered in emergency situations

bx a higher concentration could stop their respiratory drive

What are the steps for using a wall outlet oxygen system

attach flow meter to wall outlet
fill humidifier then attach to flow meter (if needed)
attach prescribed oxygen tubing and delivery device to the humidifier
regulate the flow to prescribed level

What are Non-invasive positive pressure ventilation used the most for

obstructive sleep apnea (OSA)

What are some lifespan considerations for children for suctioning

use a catheter

What are some considerations with suctioning a trach tube

only suction on the way out, limit to 5 to 10 seconds | use sterile technique

What are oro and nasopharyngeal airways used for

keeping the upper airways open in patient who might have secretions or a tongue that causes onbstruction like comatose, sedated, or patients with altered LOC

What amount of oxygen can a cannula deliver

25-45% at flow rates of 2-6L/min

What needs to be added to a dry oxygen supply

a humidifier essentially for liter flows over 4L/min

What conditions require Non-invasive positive pressure ventilation

chronic/acute respiratory failure pulmonary edema COPD obstructive sleep apnea

What are some oxygen therapy safety precautions

always smoke away from the oxygen supply place cautionary no smoking signs near the oxygen supply make sure electrical equipment is working to prevent sparks avoid materials that generate static electricity Avoid using volitile materials near the oxygen supply Teach location of fire extinguishers

What are some safety precautions for cylinder oxygen

store away from heat and high traffic | secure to something

Whats the difference between CPAP and BiPap

BiPap has two pressure settings while CPAP doesnt

Why is humidification for reservior nasal cannulas not required

because the moisture from the patient exhaling is capture and then redelivered on the next inspiration

What are some nursing interventions for clients with endotracheal tubes

Assess clients respiratory status q2h maintain a cuff pressure of 20-25 mmHg provide a picture board or note pad for communication provide oral and nasal care every 2-4hours unless contraindicated, elevate bed to 30-45 degrees

Is humidification required for reservior nasal cannulas

What are the limitations of masks

finding the right size | poor tolerance of them by the client

What are some lifespan considerations for infants for suctioning

use a bulb syringe

When can the nurse administer oxygen tharapy

with an order from the PCP | during emergencies without a PCP order

What is a special consideration for venturi masks

they have multiple sizes for tubing which are typically color coded for a specific O2 concentration so make sure you have the right tube

How do you determine the correct size suction catheter for ETT (endotracheal tubes) or tracheostomys

double the millimeter size of the artificial airway being used. for example if a 8mm tracheostomy is used the max size catheter that should be used is size 16

What kind of patients usually get face tents

anesthesia patient s

How does CPAP and BiPap work

they keep the alveoli and airways open

Because oropharyngeal airways stimulate the gag reflex they are only used on who

patients with altered LOC like anesthesia, head injuries, and overdoses

What are some lifespan considerations for older adults for suctioning

watch for signs of hypoxemia, stop and hyperoxygenate if you see signs

What does some nursing care of trachs involve

cleaning and suctioning

What are the two types of tracheostomy's

normal | cuffed

What is the advantage of cuffed trachs

their Airtight seal prevents aspiration and air leakage

Are humidifiers required for normal cannula

yes

What are the two types of reservior nasal cannulas

pendant style | mustashe style

What are the four most common artificial airways clients can have

oropharyngeal nasopharyngeal endotracheal tracheostomy

What are the limitations of cannula

they cant deliver high concentrations of oxygen | they can dryout mucous membranes

What does FiO2 mean

fraction of inspired O2

How much oxygen concentration can a simple face mask deliver

40-60% at liter flows 5-8L/min

What does BiPap stand for

bilevel positive air pressure

What are the complications associated with suctioning endotracheal or tracheostomy tubes

hypoxemia infection cardiac dysrythmia

What fraction of O2 can a reservior nasal cannula deliver

0.5 or greater

What O2 concentration can face tents deliver

30-50% at liter flows of 4-8L/min

What type of schedule is suctioning usually on

as needed based on respiratory distress or inability to expectorate
