In the case the principle investigator (PI) or a member of the study team positively confirms vasospasm based on clinical assessment or follow-up care of the patient during the monitoring period, the patient will be recorded twice daily for up to a consecutive 14 days or for their duration in the ICU. The PI will determine the severity of vasospasm as per the vasospasm severity scale. Increased recording frequency will be implemented only for patients with vasospasm graded as asymptomatic moderate-to-severe or symptomatic mild-to-severe (i.e. those scoring 2a, 3a, 1s, 2s, or 3s).
