Q

What is the one-way valve on the on the nonrebreather mask for?

A

The valve enables the patient to draw required oxygen from the reservoir bag, while the flaps prevent room air from entering through the exhalation ports. During exhalation, air exits through these ports, and the one-way valve prevents exhaled air from re-entering the reservoir bag.

A

breathe both through the tube and the upper airway

278
Q

If the patient is tolerateing the deflated cuff, what should happen next?

A

the tube is exchanged for an uncuffed tube

279
Q

If the patient tolerates the uncuffed tube and the changes that comes with the different airway, what happens next?

A

the tube size is progressively reduced

280
Q

After the patient tolerates the smaller tube what kind of tube comes next in the weaning process?

A

a small fenestrated tube

281
Q

When the patient is introduced to a smaller fenestrated tube during the weaning process, what do patients have to get used to with this particular tube?

A

when the tube is capped, it allows all air to pass through the upper airway and fenestrations with none passing through the tube

282
Q

What should be assessed when patients are introduced to the fenestrated tube during the weaning process?

A

assess the patient to ensure adequate airflow around the capped tube

283
Q

When does tube removal become feasible in the weaning process?

A

once the patient successfully tolerates more than 24 hrs of capping

284
Q

After the removal of the tubing, what should happen with the stoma site?

A

a dry dressing is applied over the stoma, which gradually heals naturally

285
Q

What is an alternative device for facilitating the transition from tracheostomy to natural breathing?

A

the tracheostomy button

286
Q

What does the tracheostomy button maintain?

A

the stoma’s patency while supporting spontaneous breathing

287
Q

Upon discharge, what should the patient be able to perform?

A

self-care taskts, such as tracheostomy care, nutritional care, suctioning, and communication

288
Q

While some education is provided before the tracheostomy surgury, when does the majority of the self-care instructions take place?

A

during hospitalization

289
Q

Who needs to be instructed on trach tube care, clean suctioning technique, airway maintenance, cleaning techniques, abd signs of infection or impaired tissue integrity?

A

the patient and caregiver

290
Q

What should you teach the patient regarding showering?

A

use a shower shield over the tracheostomy tube to prevent water from entering the airway

291
Q

What should be used during the day to filter the air entering the stoma, maintain humidity in the airway, and enhance overall appearance?

A

a small cotton cloth should be used to loosely cover the tube

292
Q

What should be taught to be increased in the home when the patient is discharged home?

A

the humidity within the home environment

293
Q

What should be worn by the patient that communicates their inability to speak and ensures appropriate awareness in emergency situations?

A

a medical alert bracelet

294
Q

KEY POINTS for quick studying: chapter 25

A
  • Never allow water condensation in an oxygen delivery system to drain back into the system
  • Use sterile technique when performing endotracheal or tracheal suctioning
  • Assess tissue integrity of the oral mucous membranes for injury or infection each shift for anyone who has an endotracheal tube
  • Keep a tracheostomy tube (and obturator) and tracheostomy insertion tray at the bedside, and ensure that tracheostomy care is performed with two licensed personnel for the first 72 hours after a tracheostomy has been created
  • Verify safe use of oxygen delivery systems and tracheostomy equipment
  • Keep the tracheal cuff pressure between 14 and 20 to prevent loss of tissue integrity
  • Teach the patient and caregivers about home management of oxygen therapy, including the avoidance of smoking or open flames in rooms in which oxygen is being used
  • Teach the patient and caregivers how to perform tracheostomy care
  • Ensure that the patient and caregiver(s) know whom to contact about needed supplies and durable medical equipment
  • Allow the patient and family to express concerns about a change in breathing status or the possibility of intubation and mechanical ventilation
  • Teach caregivers and family members ways to communicate with a patient who is intubated or being mechanically ventilated
  • Reassure patients who are intubated that the loss of speech is temporary
  • Apply oxygen to anyone who is hypoxemic
  • Monitor arterial blood gases (ABGs) and oxygen saturation of all patients receiving oxygen therapy
  • Assess the skin under the mask and under the plastic tubing every shift for patients receiving oxygen by mask
  • Assess the tissue integrity of the nares and under the elastic band every shift for patients receiving oxygen by nasal cannula
  • Assess patients receiving oxygen at a 50% concentration or higher for early indications of oxygen toxicity (i.e., dyspnea, nonproductive cough, chest pain, GI upset)
  • Use a manual resuscitation bag to ventilate the patient if the tracheostomy tube has dislodged or become decannulated
  • Assess the new tracheostomy stoma site at least once per shift for purulent drainage, redness, pain, and swelling as indicators of infection or loss of tissue integrity
