You place a patient on SIMV with a preset rate of 8/min, a Vt of 500 ml and 10 cmH2O of PEEP. You notice a peak pressure of 25 cmH2O for each breath. Which of the following alarm settings would be appropriate?I. low exhaled minute ventilation alarm at 5 L/mII. low PEEP/CPAP pressure alarm at 5 cmH2OIII. high inspiratory pressure limit at 40 cmH2OIV. low exhaled volume alarm at 500 ml

For the above patient, what is recommended?

A patient in ER is in severe respiratory distress. The patient is a known COPD patient who is normally on home oxygen at 1 L/m. The patient is placed on a nasal cannula at 4 L/min. After 4 hours, the patient is lethargic and breathing slow and shallow. ABGs reveal a Ph of 7.25, PaCO2 of 70 and a PaO2 of 80 mmHg. The patient is most likely suffers from:
