MH CI (7) |
Haemodynamic Instability Suspected or undrained pneuomothorax Large bullae Severe bronchospasm or asthma Obstructive lung disease High positive end expiratory pressure (PEEP>10cmH2o on ventilator) Severe head injury with ICP < 20 mmHg |
|
|
Why is Haemodynamic Instability a CI for MH |
Decreases in cardiac output and blood pressure put patient at risk if already hypotensive |
|
|
Why should you be careful with a treated pneuomothorax when preforming MH |
If leakage is large with UWSD hyperinflation may worsen presentation
|
|
|
Why is large bullae a CI for MH |
Reduce risk of rupture |
|
|
Why is severe bronchospasm and asthma a CI for MH |
Delivery of un humidified gas may worsen bronchospasm and incerase risk of barotrauma |
|
|
Obstructive lung disease eg COPD - why CI for MH |
Patients with COPD are at risk of gas trapping - need sufficient expiratory time |
|
|
Why is high PEEP and CI for MH |
Patient may not tolerate discconecting from ventilator |
|
|
Indications for MH (3) |
Mobilise and facilitate clearance of secretions Recruit/ Reinflate atelectaic areas of lung Improve lung compliance |
|
|
Suction CI (6) |
Unexplained haemoptysis Severe coagulopathies Severe bronchospasm Laryngeal spasm Compromised cardiovascular system Head injuries with CSF leak into nasal passage - if done via nasopharyngeal |
|
|
Suction Indications |
Stimulation of cough (ineffective cough) Removal of secretions (Retention clearance) |
