Q

Suctioning

A

Process of removing foreign matter by means of a mechanical or manual device.

2
Q

How long do we suction for?

A

15 - 30 seconds in an outward motion or until the airway is clear.

3
Q

Suction Tip

A

A flexible or rigid piece of tubing attatched to the end of a suction device and placed in the mouth or throat of a patient.

4
Q

How to Measure a Suction Device

A

Measure the length from the patient’s earlobe to the corner of their mouth.

5
Q

Crossed Finger Technique

A

A way of opening a patient’s mouth by using the index finger and thumb, and pushing in an outward scissor motion.

  • Cross the thumb and index finger
  • Place the thumb on the patient’s lower front teeth
  • Place the index finger on the upper front teeth
  • Open mouth using a scissor motion
6
Q

Suction steps

A
  • Measure the suction tip
  • Remove an OPA if it is in the way
  • Open the mouth using the crossed finger technique (CFT)
  • Suction until the airway is clear in an outward motion
  • Reinsert the OPA
  • Apply oxygen
7
Q

Oropharyngeal Airway (O P A)

A

A device inserted into the mouth of an unconscious patient to keep the tongue off of the back of the throat.

Will not secure or maintain an airway on its own.

8
Q

Measuring an OPA

A

The device should be the length between the patient’s earlobe to the corner of their mouth.

9
Q

Insertion of an OPA

A
  • Open the mouth using the CFT
  • With the curved end of the OPA facing the roof of the mouth, insert the OPA
  • As the tip of the device approaches the back of the throat, rotate it a half turn
  • If patient gags, remove the device
  • If patient does not gag, continue insertion until the flange of the OPA rests on the patient’s lips
  • The OPA should drop in without resistance
10
Q

Oropharyngeal Airways in Babies and Children

A

If the usual method does not work, insert with tip pointing toward cheek, rotating 90 degrees to place it in the throat.

You may need to use a tongue depressor on babies and just insert in position without rotating.

11
Q

Nasopharyngeal Airway (N P A)

A

A tube placed in the nostril to assist in maintaining an airway.

12
Q

Measuring an NPA

A

Measure device from earlobe to the tip of the nose

13
Q

Insertion of an NPA

A
  • Lubricate the airway
  • Insert NPA with the bevel toward the septum
  • Advance it gently and straight in until the flange rests against the nose

DO NOT USE ON HEAD / SPINE TRAUMA

14
Q

Epistaxis

A

Nose Bleed

15
Q

Resuscitation Mask

A

Pliable, dome shaped device placed over a patients nose and mouth to provide a barrier during rescue breathing.

Your RM should be pliable, have a one way valve, and an inlet for supplemental oxygen.

16
Q

Bag Valve Mask

A

A device consisting of a bag, a valve, and a mask. Used for assisted ventilations during rescue breathing.

17
Q

Nasal Cannula

A

A device placed slightly inside the nostril to deliver low flow oxygen to a conscious patient.

18
Q

Non-Rebreather Mask

A

A mask that fits over a patient’s nose and mouth that provides supplemental oxygen. Also has a little bag on it that fills up. Make sure that little bag is full before handing this to the patient.

19
Q

Oxygen Cylinder

A

A tank full of 100% medical grade oxygen characterized by a green or white color and yellow oxidizer placard.

20
Q

Formula to determine how long an oxygen tank will last

A

(((Gauge Pressure) - (200 psi)) x Cylinder Constant) / (L / minute)

ie:
M Tank = ((2000 psi - 200 psi)(1.56 L/psi)) / (15 L/min)
=187.2 minutes

21
Q

Cylinder Constant

A
D = 0.16 L/psi
E = 0.28 L/psi
M = 1.56 L/psi
22
Q

Pressure Regulator

A

Device that reduces the pressure of an O2 tank from approximately 2000 psi to a safe pressure range of 30 - 70 psi

23
Q

Flowmeter

A

Device that controls the amount of oxygen administered in litres per minute (lpm)

24
Q

How to Assemble an Oxygen Tank for Use

A

Inspect the tank for any damage and make sure it is labeled correctly

  • Make sure the cylinder is full
  • Remove the protective covering and keep the O-ring
  • Open the cylinder for a brief second to clear the valve of debris.
  • Position the gasket.
  • Examine the pressure regulator to make sure the pin index corresponds to the O2 tank.
  • Attach the pressure regulator, seating the prongs inside the holes in the valve stem.
  • Hand tighten until snug
  • Open the cylinder one full turn to check for leaks
  • Check to see how much pressure is in the cylinder, full tanks should be around 2000 psi
  • Attach the delivery device to the port
  • Turn on the flowmeter to the desired flow rate
  • Check to see that O2 is flowing through the delivery device.
  • Inflate device bag, and hand to /place on patient
25
Q

Oxygen Cylinder Precautions

A
  • Do not operate around open flame or sparks, or within close proximity to an AED
  • Do not stand tank upright unless it is well secured
  • Do not use grease, oil, or petroleum products to lubricate any parts. A severe chemical reaction could cause an explosion.
