Clinical trials: Respiratory Muscle Blood Flow
Cardiac Surgery With Extracorporeal Circulation, Thoracic Surgery
Evaluation of the Prognostic Value of Preoperative Quadriceps and Respiratory Muscle Thickness by Ultrasound Measurement in Cardiac and Thoracic Surgery Patients
Cardiac and thoracic surgery are major procedures. In order to estimate the operative risk, many scores have been developed, including the Euroscore 2 in cardiac surgery.

Pulmonary Arterial Hypertension
Peripheral Muscle Microcirculation and Exercise-induced Blood Flow Distribution in Pulmonary Arterial Hypertension
Pulmonary artery hypertension (PAH) is a rare, severe disease, characterized by a progressive increase in pulmonary vascular resistance ultimately leading to right ventricular (RV) failure and premature death.

Cystic Fibrosis
Blood Flow and Vascular Function in Cystic Fibrosis
Cystic fibrosis (CF) has many health consequences. A reduction in the ability to perform exercise in patients with CF is related to greater death rates, steeper decline in lung function, and more frequent lung infections.

- Sildenafil (Acute-1 hour), Sildenafil (Subchronic-4 weeks)
- Where
- United States
- Volunteers
- 19 people, healthy volunteers welcome

Hypoxia, Altitude, Blood Flow Restriction
Effects of Low-Intensity Blood Flow Restriction Training in Normoxia and Hypoxia Conditions
One approach to significantly reducing resistance training intensity while maintaining effectiveness in muscle mass and strength development involves conducting training sessions under hypoxic conditions.

Respiratory Muscle Blood Flow
Clinical Respiratory Evaluation Using Spectroscopy Trial
Respiratory muscles (the muscles used to breathe) need more blood (and oxygen) when their workload increases. It is difficult to measure respiratory muscle blood flow (RMBF) without invasive techniques.
- Trial name
- CREST (NCT01321411)
- Testing
- Near Infrared Spectroscopy
- Volunteers
