To investigate the evidence for the integration of hyperbaric oxygen therapy (HBOT) as part of interdisciplinary stroke rehabilitation.
Pneumonia complicating stroke is very difficult to manage and has a very poor prognosis, leading to a significantly higher risk of death. Oral opportunistic pathogens have been reported to be associated with the incidence of pneumonia among non-stroke immunocompromised subjects. Preliminary studies found that patients with stroke had higher carriage rates of oral opportunistic pathogens than healthy subjects. Therefore, investigators hypothesize that pneumonia complicating stroke is associated with oral opportunistic pathogens, and hyperbaric oxygen therapy may reduce the incidence of pneumonia complicating stroke by increasing the flow of saliva, which can affect the species and relative abundance of oral opportunistic pathogens. In order to prove this, investigators need to (1) firstly conduct a randomized controlled trial to confirm whether hyperbaric oxygen therapy is able to reduce the levels of plaque, and the incidence of pneumonia complicating stroke at clinical level; (2) secondly employ metagenomics analysis to compare oral rinse samples and respiratory samples, and to identify pneumonia-associated "oral opportunistic pathogens group"; (3) finally elucidate how hyperbaric oxygen therapy influences the species and relative abundance of oral opportunistic pathogens. This proposed study will provide evidence for the integration of hyperbaric oxygen therapy as part of interdisciplinary stroke rehabilitation.

Hyperbaric oxygen therapy is the patient put in airtight oxygen tank, by increasing the air pressure in the environment (1.5 to 3.0) under atmospheric pressure, to give 100% oxygen, the patient treatment time is approximately 60 minutes to 120 minutes in this way, can achieve the purpose of greatly increase the oxygen partial pressure in the organization, so as to achieve reverse brain edema, reduce lipid peroxidation, inhibiting leukocyte hyperactivity, rebuild the blood brain barrier.

Incidence of pneumonia
To calculate and compare the incidence of pneumonia between interventional group and control group, to identify whether the intervention approach could reduce the incidence.
Time frame: 2 months
Metagenomics
To analyze and compare the effect of intervention on the diversity of bacteria in saliva samples and lower respiratory sputum samples.
Time frame: 2 months
Short Form Health Survey 12 (SF-12)
The concise health status scale (SF-12) IS used to assess the systemic health-related quality of life in stroke patients. It covers eight different areas: general health (GH), physical functioning (PF), bodily pain (BP), role-physical (RP), mental health (MH), vitality (VT), social functioning (SF), role-emotional (RE). The SF-12 consists of 12 items, and each of them has its own physical component summary (PCS) and mental component summary (MCS) regression coefficients. The response to each item will be multiplied by its PCS regression coefficient and added together with the PCS constant to provide Physical Health summary scores (SF-12 PCS). Mental Health summary scores (SF-12 MCS) will be calculated likewise. The higher the score, the higher the quality of life.
