Oxygen therapy Mechanical stimulator Nasal CPAP / SIMV-CPAP BI-PAP Mechanical ventilation RESPIRATORY SUPPORT
Respiratory Assessment • Is the patient Ventilating well? >>> Normal PCO2 • Normal ventilatory effort • Increase work of breathing • Able to compensate • Is patient getting exhausted >> Impending respiratory failure • Is the patient oxygenating well? >> Normal Pa O2 • Assess oxygen requirement • A-a gradient Vs PaO2/FiO2 >> Hypoxic respiratory failure?
Respiratory Assessment • Mental Status (Is patient being sedated) • RR (according to age) • Work of breathing (retraction, nasal flaring, paradoxic breathing) • Chest movement-Air-entry • Adventitious sounds (Stridor-wheezes, crackles) • Oxygen requirements • Cardiovascular status, (Compensatory mechanisms: HR, BP, perfusion) • Peak Flow • ABG
Respiratory Mechanics • Flow • Compliance (degree of stiffness) Compliance = Volume Pressure • Resistance = = Pressure Flow • Time Constance
ARF In the absence of intracardiac shunt. • Pa02 < 50 mm Hg • PC02 > 50 mmHg • Increase PaO2/Fio2 < 200 (Normal >400) • Increase A-a gradient (>300) (PaO2 60 on FiO2 of 0.6 = 100)
Indication for Intubation • For Airway protection • Facial Trauma • Alter mental status • Recurrent Apnea • Respiratory Failure • Hypoventilatory • Hypoxic • Mix • Cardiovascular instability- Shock
INDICATION FOR INTUBATION AND MECHANICAL VENTILATION IN STATUS ASTHMATICUS • Alter sensorium / Coma • Inability to speak • Increasing pulsus paradosus • Signs of exhautioon (decreasing pulsus paradosus • Respiratory or cardiac arrest • Diaphoresis in the recumbent position • Acute Barotrauma • Severe Lactic Acidosis (specially in infants) • Silent chest despite respiratory effort • Refractory hypoxemia (PaO2 < 60 mmHg on maximal O2) • Increasing PaCO2 (50 mmHg and rising > 5 mmHg/hr)
General Principles Approaches to Lung Protection • Small tidal volumes/pressure limitation • Prevent Barotrauma • Prevent Volutrauma • Recruitment maneuvers, with • Higher PEEP levels • Ventilation in the prone position
OXYGEN THERAPY“Low Flow Oxygen < 35 %” • Nasal Cannula: • No more than 3L/min • Each L/min delivers ~ 4 % Oxygen > RA • At low flows, no need to humidify • Simple Mask • Use for an emergency/ transport • Deliver ~ 30% at 6-8 L/min
OXYGEN THERAPY“Moderate Amount= >35% < 50%) VENTURY MAST: 28% TO 50 % AEROSOLIZED MASK 25% TO 100%
Oxygen Delivery High Flow • Non re-breathing mask • high flow delivered system • with reservoir, • It deliver between 80 to 100% • FiO2. • This deliveringSystem is use • mainly for transport and for • initially emergency care and • patient stabilization.
