An apneic 55 kg (IBW) patient is being ventilated with a volume ventilator in the CMV mode. Her vent settings are as shown: Rate 12, Vt 550, FIO2 60%, Mechanical deadspace 75 mL Her ABG’s show 7.32/52/56 Considering this information, all these individual ventilator adjustments would improve her ABG’s EXCEPT:

A 28 year old man presents in the ER after being involved in an MVA. The patient sustained multiple rib fractures bilaterally. Vital Signs: Spontaneous Ventilatory Parameters HR 120 Vt 200 BP 160/100 VC 500ml Temp 98C. Blood Gas results on RA 7.21/75/50/26/84%.  Thirty minutes after initiating mechanical ventilation, the following ABG’s are obtained on 40% 7.29/58/160/25/99%  Which of the following would be MOST appropriate interventions for this patient?

You are ventilating an adult female with a Hamilton-G5 in APVcmv. Her weight is 120 lb (IBW) and her settings are: Rate 14 (patient is assisting at 20), Vt 800ml, FIO2 30%, Itime 1.2 seconds, PIP 38, Pplat 30, PEEP 5ABG’s on these settings are 7.49/32/58/23/89% What would be the most appropriate change (if any) to correct the PaCO2? What would the new setting be? What change would be the most appropriate (if any) to correct the PaO2 and SaO2? What would the new setting be? What is the static compliance? Is it normal, high or low?

A 35-year-old patient is being mechanically ventilated with SIMV and these settings: rate 12, Vt 850, PS 16, 45% FIO2. He is not breathing spontaneously. Based on these settings, he has the following ABG’s 7.5/29/94/23/98%.  The physician is not pleased with these values. What would you recommend to correct them?

You are working with a 176 lb patient who is apneic after suffering a stroke. He is being ventilated in CMV mode with the following settings: MV 8 L Rate 10 I:E 1:3 FIO2 40% Mechanical dead space 200 ml The ABG’s show 7.3/50/90/24/95% You would recommend which of the following:

A COPD patient receiving CMV A/C ventilation with a rate of 14 and a VT of 750 exhibits clinical signs of air trapping. Which of the following would you recommend to correct this problem? Decrease E time Increase inspiratory flow rate Decrease the A/C rate

A order has been written for RT to  find the optimum PEEP level for a mechanically ventilated patient. Which of the following would be expected to be at its highest value when the optimum PEEP level is reached? Oxygen delivery Static compliance Physiologic dead space Physiologic shunt

Monitoring waveforms during mechanical ventilation is useful for 4 main reasons. Name 2.

Why is the internal MutableStateFlow in a ViewModel declared as private, while a separate read-only StateFlow is exposed (public) to the UI? For example: class AppViewModel : ViewModel() { private val _uiState = MutableStateFlow(AppUiState()) // read/write val uiState: StateFlow = _uiState.asStateFlow() // read-only …
