Patients who fail the SBT often do so within the first 10 minutes of the trial.

Low tidal volume strategy is done to reduce the risk of ______, and the target volume is reached when ______ . 

After they had successful tracheostomy cuff deflation, it was time to introduce the bias-closed position no-leak Passy Muir Tracheostomy & Ventilator Swallowing and Speaking Valve (PMV). Noah’s ventilator settings were stable, he wanted to eat and speak again, and they had confirmed his upper airway was patent by hearing whispers of speech after his cuff deflation. However, the team met with similar obstacles when using the PMV as they had with cuff deflation. Noah was hesitant and anxious about something new, which would cause a change in his breathing. The first time they placed the PMV in-line with the ventilator, Noah agreed to use it for 10 minutes. Another consideration for success with children is to have them invested in the therapy; have them agree and assist with planning the goals. While there was much hesitation from Noah, having him assist with the plan, understand it, and using distraction while providing encouragement helped to motivate his use for 10 minutes. While it was not the easiest 10 minutes, Noah enjoyed having his voice back and being able to try tastes of Nutella. The therapist monitors the patient and determines PMV tolerance by observing the following characteristics? (Select all that apply) 

During his hospital stay, Noah was tracheostomized on June 6, 2016 with a #4 Shiley Disposable Cuffed Tracheostomy Tube. In need of intense rehabilitation, Noah was referred to The Children’s Institute of Pittsburgh and transferred to the pediatric rehabilitation hospital on June 29, 2016. The team at The Children’s Institute established several primary goals.  What does a #4 Shiley refer to? 

The unspoken motto in the facility is “slow and steady wins the race.” They needed to set Noah up for success. It was very clear from the beginning of working with Noah that they needed to approach his care with a variety of methods and instituting our keys to success. To increase our chances of success, we began by building trust, explaining the plan, and letting him begin to know the team members. What might be another consideration to help with Noah’s anxiety?

Noah remained paralyzed from the neck down as a result of the stroke. He received a #4 Shiley Disposable Cuffed Tracheostomy Tube. He was on the Trilogy Ventilator with settings of: SIMV/PC, PC 22 cmH2O (centimeters of water pressure), RR 16 bpm (breaths per minute), PEEP 8 cmH2O, PS 8 cmH2O and 2l pmO2. Given Noah’s current status, what might be the next step in moving towards PMV trials?   

As Noah wore the PMV, his ventilator settings were reduced over the next two weeks to BiPAP settings (a spontaneous, weaning mode). Once Noah had been comfortable on the BiPAP settings, it was decided to trial the tracheostomy mask. The RT removed him from the vent and placed him on a room air tracheostomy mask with humidification. Within one minute, Noah’s SpO2 dropped from 98 to 87% and he struggled to breathe. After the RT bagged him and returned his SpO2 to baseline, he was placed back on the ventilator. After several minutes on the ventilator, Noah calmed down and was able to catch his breath. He stated that the feeling was so different off the ventilator, and he was scared because he could not talk. When he finally became comfortable with the idea being off the ventilator again (still on BiPAP settings), we presented him with a new plan. We would remove him from the ventilator and place him on his PMV immediately, skipping the tracheostomy mask. We explained the reasons to him. First, being the most important to him was that he would be able to talk, which would assist with being less anxious. The second main reason to place the PMV immediately was so that his lungs did not lose pressure. How does the PMV keep Noah’s lungs from loosing pressure?

Due to the patient’s underlying issues with anxiety, the initial stages of cuff deflation and vent weaning presented a huge challenge. With the cuff still inflated, Noah was unable to vocalize and did not have an easy method to communicate with staff or family, which added to his frustration. Whenever a member of the team would try to work with him, his respiratory rate and heart rate would increase as he would become tearful and anxious with possible change. Given Noah’s current status (physical and respiratory), what might be one method of communication the SLP could implement?
