Brief Summary
The goal of this randomized crossover physiological study is to evaluate the physiologic effects of asymmetrical nasal cannula and conventional nasal cannula in patients with acute respiratory failure. The main questions it aims to answer are:
- Does the asymmetrical high-flow nasal cannula reduce the diaphragm and parasternal intercostal work activity of breathing measured by ultrasound compared to conventional high-flow nasal cannula?
- What is the effect of the asymmetrical high-flow nasal cannula on breathing pattern, gas exchange, and hemodynamic variables compared to conventional high-flow nasal cannula? Participants will received asymmetrical high-flow nasal cannula or conventional high-flow nasal cannula at a flow rate of 40 and 60 L/min in a random order.

Interventions
Asymmetrical high-flow nasal cannula will be set at 40 and 60 L/min in a random order. Temperature will be set at 37 degree celsius and inspired oxygen fraction (FiO2) will be adjusted to maintain oxygen saturation by pulse oximetry (SpO2) \>/= 94% in acute hypoxemic patients and between 92-94% in acute hypercapnic COPD patients
Conventional high-flow nasal cannula will be set at 40 and 60 L/min in a random order. Temperature will be set at 37 degree celsius and FiO2 will be adjusted to maintain SpO2 \>/= 94% in acute hypoxemic patients and between 92-94% in acute hypercapnic COPD patients
