Difference between Low flow oxygen and High flow oxygen?
Low flow - Measured in L/ min titrated 1-2L, inspiratory flow not met, and uses Nasal prongs, simple mask, non-rebreather
High flow - Measured in % titrated 5-10% at a time air needs to humidified, inspiratory flow met/exceeded
What is an AquaPak Humidified O2 system? And when does the tubing need to be changed?
An attachment that contains sterile water that humidifies the air and is an AGM not a medication. Tubing needs to be changed every 7 days
What are the three parts of a trach tube?
Outer cannula with flange
Inner Cannula
Obturator
What are the most important safety equipment for a trach tube?
Suction equipment
Oxygen equipment with humidification
Two replacement tracheostomy tubes (one the same size and one smaller)
Obturator and spare inner cannula
10 ml syringe
Less important
Tracheal tube exchanger
tracheal dilator or forceps
Sterile gloves
Water soluble lubricant
spare ties
Normal saline nebule
Manual resuscitation device with appropriate size airway and mask
What does the placement of the chest tube mean?
Upper chest tube means its draining air
Lower chest tube is draining fluid
Is a PICC a Peripheral line or a Central line?
Central line
What size is a CVAD with multiple lumens? and do you have to flush each line?
18 gage with one that is different
Yes
When would you need a PICC?
Administering IV fluids and blood products quickly
Administering Vaso medication
Chemotherapy
Administer medications with extreme PH values like cloxacillin
Obtain venous blood samples
How many ml’s do you need to flush a Central line?
10 mls before
20mls after
How many ml’s do you need to flush a peripheral line?
3mls before
10 ml’s after
Do you need a Heparin flush for Valved PICC line?
No
Why do you need to aspirate a central line?
Because a fibrin sheath can form
How often does a transparent dressing, Securement device, Needless cap need to be changed?
Every 7 days and prn
Transparent dressing- gauze needs to be changed every 2 days
Needless cap should be changed when blood is unable to clear from the needless cap
How often does a transparent dressing, Securement device, Needless cap need to be changed?
Every 7 days and prn
Transparent dressing- gauze needs to be changed every 2 days
Needless cap should be changed when blood is unable to clear from the needless cap
What to do if the external line is different by at least 2 cms?
Report to IV team and document
Complication of a CVAD?
Infection
Occlusions
Phlebitis, thrombophlebitis, infiltration, extravasation
Catheter migration
Air embolism
Catheter embolism
Pneumothorax/ hemothorax
Arrhythmia
How to deal with a venous air embolism?
Lean the patient on the left side and in Trendelenburg position to move air bubble into right right atrium.
If it is an arterial air embolism should be kept in supine position
What ml syringe is the smallest you can use with a peripheral line and why?
10 ml due to the idea it can only exert 8 PSI anything smaller is too much pressure
What to do if an IV push med is incompatible with the IV solution?
Stop IV line, pinch the line, aspirate, flush with 10ml, administer the medication abiding my the time required to administer, and 10 ml post med flush.
What causes a catheter Occlusion? S&S? Interventions?
Clamped or kinked catheter, Tip against wall of vessel, Thrombosis, Precipitate build up in lumen
S&S- Sluggish infusion or aspiration, unable and/or aspirate
Intervention - Check IV line, flush with saline, anticoagulant or thrombolytic agent
What causes an Embolism? S&S? Interventions?
Catheter breaking, Dislodgement of thrombus, entry of air into circulation
S&S - Chest pain, Respiratory distress (dyspnea, tachypnea, hypoxia, cyanosis), hypertension, tachycardia
Interventions - Clamp catheter, place patient on left side with head down( if suspect or emboli), Administer oxygen, notify physician
What is the cause of pneumothorax? S&S? and Interventions?
Inadvertent puncture of the lung at the time of inserting needle in vein
Decreased or absent breath sounds, respiratory distress (cyanosis, dyspnea, tachypnea), chest pain, distended unilateral chest
Interventions - Position in semi Fowler’s position, administer O2, administer analgesic if ordered, Prepare for xray/chest tube insertion
What causes Catheter migration? Signs and Symptoms? Intervention?
Improper suturing, insertion site trauma pressure, changes in intrathoracic pressure, forceful catheter flushing, spontaneous
Sluggish infusion or aspiration, edema of chest for neck during infusion, Client complaint of gurgling sound in ear, Dysrhythmias, Increased external catheter length
Fluoroscopy to verify position, assist with removal and new CVAD placement
Where are Non tunneled CVAD’s located?
Jugular, femoral, and subclavian
When would you want to use a non tunneled CVAD?
Short term emergency therapy, external jugular, or subclavian vein
Requires a sterile dressing
Non valved
Only good for 7 days or less due to risk of infections
When would you use a CVAD?
Used for long term intermittent or continuous access
to Administer …
- Chemo therapy, Vasopressors or dilator, give large volumes of IV and normal IV, irritant medications, Extreme PH values, hypertonic solutions, obtain venous blood samples, and monitor central venous pressure
Proximal end is tunneled subcutaneously from the insertion site 10-15 cm
Have a Dacron Cuff on the tunneled portion of the catheter 3-4 weeks so granulation tissue can form around it
When would you use an IVAD (Implanted Vascular Access device?
Located in the upper chest that connects to the distal third vena cava of superior vena cava
Used for chemo therapy (aka people who need a port very long term outside the hospital)
Requires heparin flush every 8 weeks to maintain patency
When would a hemodialysis cuff would need a cuff?
Uncuffed - used for an emergency or less than 3 months
Cuffed - longer than 3 months
Things to know if giving TPN through CVAD
Total parenteral nutrition is given through CVAD and Partial parenteral nutrition is given with PVAD
Needs a dedicated line and an inline filter
What happens when there is Unilateral dilation in the eyes?
Brain hematoma
Brainstem herniation
Migraine
Compressed cranial nerve 3
Why is there Bilateral Dilation with fixed versus sluggish pupils?
Mid brain injury
Poor prognosis if GCS less than 3
Patient is approaching death
Sluggish -
Eye disease
Illicit substances
Post seizure
What does bilateral Constriction mean?
Brain trauma (pons CVA)
