Filter by:A study of how supplemental oxygen helps patients with acute pulmonary embolism (PE). Hypothesis: Oxygen affects right ventricular dysfunction (RVD) in patients with acute pulmonary embolism (PE) primarily by relieving hypoxic pulmonary vasoconstriction and reducing pulmonary pressure (PA) pressure, and that this process is metabolically driven.
This study is meant to compare the amount of oxygen required for hypoxemia relief between current standard of care (oxygen only) and oxygen with the addition of high flow air for Chronic Obstructive Pulmonary Disease (COPD), Interstitial Lung Disease (ILD), and Pulmonary Hypertension (PH) patients during rest. Subjects will be titrated from 0 L/min until they maintain 95% SpO2 for each of the following delivery methods: 1. Pulses of pure oxygen (control) 2. Constant high flow air with pulses of pure oxygen 3. Out of phase pulses of high flow air and pure oxygen
Long term oxygen therapy (LTOT) is proven to increase the survival of patients with respiratory failure, most commonly from diseases such as Chronic Obstructive Pulmonary Disease (COPD). At least 15 hours' usage per day is needed to improve mortality. Most patients on LTOT utilise bulky oxygen concentrators (OC) which run on continuous Alternating Current (AC) power. This intervention, however, limits patient mobility and social engagement as patients are tethered to their device and confined to their homes. Reduced physical activity levels have been shown in COPD patients to be associated with reduced quality of life (QoL), increased admission rates to hospital and survival even after adjustment for severity of COPD. Significant benefits stand to be made by improving physical activity levels in LTOT patients. Pulmonary Rehabilitation (PR), which is traditionally conducted in a healthcare setting, is an established intervention that addresses this by improving exercise tolerance but uptake and completion rates have been low due to reasons such as cost and difficulty with transport. LTOT usage is also cited as an independent barrier to PR. The investigators propose the establishment of a 10-week home-based physiotherapy programme as a novel community-centric and resource-lean intervention that seeks to improve the physical activity level of LTOT patients. Patients will be prescribed an ambulatory oxygen device and receive education on its usage in conjunction with a home exercise regimen which includes a home visit and subsequent telephone support by a physiotherapist in partnership with a community-based healthcare provider. A prospective pilot study of 30 patients is proposed. The outcome measures include mobility function, activity levels, generic and disease-specific QoL. If successful, our programme may revolutionize the approach to LTOT patients in Singapore and improve their ability to function independently in the community greatly; in addition, the reduction in hospital-based healthcare utilisation is greatly advantageous.
