Was found to be hypoxic and required 6 L of oxygen to saturate normally.  Was vaccinated with MRA vaccine but not posted.  Was started on Rocephin and doxycycline.  Inflammatory markers followed carefully.  Was started on Decadron and remsdesivir and would complete the course of the latter but be maintained on Decadron secondary to clinical issues as delineated below.  Was followed by pulmonology and Infectious Disease service.  On 01/23/2022 after initially having some improvement had worsening hypoxia and shortness of breath.  Required significant titration of his oxygen to 14 L to saturate normally.  He was transferred to the ICU.  CT scan showed worsening pneumonia.  Secondary to his myasthenia gravis diagnosis and contributions from that issue neurology consult was obtained.  Was requiring BiPAP as well.  Oxygen was titrated to high-flow.  Was started on plasmapheresis on 01/29/2022.  Completed a course of that but did not seem to have any alleviating affect on my senior gravis symptoms.  Was positive for pneumomediastinum on 02/01/2022.  Subsequently found to have pneumothorax 02/09/2022.  Had pneumopericardium as well.  Right chest tube was placed and he was taken urgently to the OR where he underwent median sternotomy, mediastinal exploration, pericardial window placement, chest tube insertions.  Return to the ICU on pressors and hemodynamically unstable.  Had been intubated and was not possible to extubate at that point.  He remained intubated throughout the rest of his hospital stay.  Blood pressure remained labile throughout the rest of his hospital stay he required intermittent pressor.  Was on Dilaudid drip and other pain medications throughout the rest of his hospital stay but not paralyzed secondary to the myasthenia gravis and worries that it would exacerbate.

There were difficulties with breathing over the vent and when his pain medication/sedation would be turned down he would have issues with the synchronizing with the ventilator.  He underwent tracheostomy and PEG tube placement on 02/17/2022.  His mental status never improved.

There were frequent meetings with family members in particular patient's wife to apprise her of the ongoing issues.  Patient showed no improvement clinically through the end of February.  Continued to have difficulties with weaning from sedation because he would become tachypneic.  Was having intermittent arrhythmia is requiring atropine.
